Oxford: Oxford University Press. French pronouns in cognition Abstract This chapter applies a cognitive theory of language – Word Grammar – to the analysis of French pronoun clitics, with default inheritance as the underlying logic. It outlines the relevant cognitive apparatus that seems to be available in general cognition, then shows in general terms how this apparatus supports autonomous morphology, default morphology and the treatment of clitics as words realized by affixes. It then turns to French pronouns, with separate formal network analyses for enclitics, proclitics, and clitic-climbing to auxiliaries (arguing that other kinds of clitic-climbing are syntactic rather than morphosyntactic). Finally it draws the following five general conclusions and two specific ones about French clitics: 1. The formal apparatus of general cognition is sufficient for an analysis of French clitics. 2. Default inheritance and ‘isa’ hierarchies provide just the right amount of flexibility to accommodate all the French facts into a unified analysis which makes no distinction between grammar and lexicon. 3. Language is a symbolic network, so linguistics needs a network model. 4. Relational concepts can be created as needed, giving important extra flexibility in analysis. 5. Morphology is an autonomous level of analysis defined by units and relations. 6. French unstressed pronouns are clitics rather than inflectional affixes. 7. French enclitics (with affirmative imperatives) are simple clitics, in contrast with the complex proclitics. This being so, they are a syntactically non-default category with a morphologically default realization. 1 French pronouns in cognition This chapter focuses on one particularly well-studied and apparently well-understood area of morphology: the unstressed pronouns of French, illustrated in (1). (1) Je te le donnerai I to.you it will.give ‘I will give it to you’ The aim of the chapter is to suggest ways in which a ‘cognitive’ orientation affects the analysis. The chapter will assume a set of assumptions that have evolved since 1980 under the name ‘Word Grammar’ (Duran-Eppler 2011; Gisborne 2010; Hudson 1984; Hudson 1990; Hudson 1998; Hudson 2007; Hudson 2010; Sugayama 2003; Sugayama and Hudson 2006; Traugott and Trousdale 2013), which is one of the theoretical models in the tradition called ‘cognitive linguistics’ (Croft and Cruse 2004; Evans and Green 2006; Geeraerts and Cuyckens 2007), alongside Cognitive Grammar and Construction Grammar. As its name suggests, cognitive linguistics aims to model language as a cognitive system – in other words, as knowledge of language, or as Chomsky’s ‘competence’ or ‘Ilanguage’; and to some extent the same could, of course, be said of almost every modern theoretical approach. But the distinctive characteristic of cognitive linguistics lies in the second of what we might call the ‘cognitive assumptions’ in (2). (2) The cognitive assumptions: a. The reality which cognitive linguistics tries to model is the individual user’s knowledge of language. b. Knowledge of language is an example of domain-general knowledge. In other words, ‘knowledge of language is knowledge’ (Goldberg 1995:5), so, as a scientific hypothesis, the mental apparatus needed for learning and processing language is the same apparatus that we use in other parts of our mental life – for remembering people and their relationships, for recognising places, for organising our social behaviour, and so on. The present paper aims to show that, in the analysis of linguistic systems such as morphology, the cognitive assumptions matter. There are three reasons why they are important. First, they predict that every structural pattern found in language can be matched by a non-linguistic pattern with the same formal properties, so, as a methodological principle, we should try hard to avoid ‘special’ structures that have no equivalent outside language. If we fail, then we shall have found really strong evidence for the uniqueness of language, whereas if we build uniqueness into the framework from the start, we shall learn nothing. A truly minimalist linguistic theory makes no special formal assumptions about language knowledge at all. This principle challenges any theory to produce non-linguistic analogues for linguistic structures, in contrast with most current practice. The second consequence of the cognitive assumptions is equally important: that the full range of domain-general cognition should be made available for language. This principle is in direct conflict with the widely accepted principle of limiting the available apparatus. To take a syntactic example (which will only be marginally relevant below), phrase structure assumes that the only possible apparatus for showing relations between co-occurring words is the mother-daughter relation between a phrase and its constituents, ignoring the obvious fact that general cognition allows us to establish direct links between co-occurring events or objects, without needing to postulate ‘mother’ entities. The third important consequence of the cognitive principle is that it guarantees the ‘graceful integration’ that will eventually be needed between any theory of language structure and existing theories of cognition: a theory that aspires to account for language as a biologically based human faculty should seek a graceful integration of linguistic phenomena with what is known about other human cognitive capacities and about the character of brain computation (Jackendoff 2011:586) If we see our theories of language knowledge as part of a much more general study of cognition, then the sooner we try to reconcile the two, the better. 2 The cognitive apparatus What, then, is the cognitive apparatus that we can take for granted as the basis for linguistic analyses? The following list includes the assumptions that are relevant to the rest of this paper. Networks Knowledge consists of a symbolic network of atomic concepts, each of which is simply the meeting point of links to other concepts. This ‘network notion’ (Reisberg 2007) is inspired by Stratificational Grammar (Lamb 1966; Lamb 1998) but is incompatible with other current views of language structure, including those which view language as a network of lexical items, constructions or attribute-value matrices (Langacker 2007; Goldberg 2006; Pollard and Sag 1994). The network notion is massively supported by evidence from priming experiments which show how activation ‘spills over’ from active concepts to their neighbours in the network. Node creation The network is highly dynamic, and allows us to create new nodes to handle our experiences as perceivers or actors; so for example we create a new node for an observed object before we ‘recognise’ it by attaching it to a permanent node in the network, thereby integrating this new node in the total network. Most new nodes fade away and die within seconds, but some turn into permanent memories. The evidence for these temporary nodes lies in memory experiments which show our unsurprising tendency to recall recent events more easily than more distant ones. Recycling Recent research in graph theory (Barabási 2003; Barabási 2009) has revealed a curious fact about the networks that humans build, from social networks to airport networks and the internet: they tend strongly to be ‘scale-free’, meaning that they have far more richly-linked ‘hubs’ than would be expected if the links were distributed randomly. The obvious explanation for this fact is that when we innovate we always have to start where we already are, with our existing concepts and infrastructure; and consequently we tend to innovate by ‘recycling’ existing structures, with a strong preference for structures that are already well developed – i.e. richly networked. The principle behind this is well known: (3) The rich get richer. We tend to enrich existing structure and to favour richly linked nodes. For example, if we need an airport, it is easier to use one that already exists than to build a new one; and similarly, if we want to add a new concept, we have to link it to existing concepts. This will have consequences for the theory of morphology in section 4. Classification Most concepts are classified as examples of more general concepts by the elementary ‘isa’ relation, e.g. ‘robin isa bird’. This is the relation not only between specific and general categories in the permanent network, but also between newly-created nodes and their permanent models. The term ‘isa’ comes from AI, where it is assumed to facilitate generalisation, so the massive evidence for generalisation also supports the ‘isa’ relation. It also supports the idea of ‘isa’ hierarchies, e.g. ‘robin isa garden-bird isa bird isa creature’. Relations The links between concepts are not mere associations, but are typed – classified so that we can distinguish our friends from our enemies, opposite and adjacent sides, preceding and following events, and so on and on. The most obvious evidence for this classification lies in our relational vocabulary, but everyday experience confirms that we distinguish relations even when we are not talking about them – e.g. we can systematically locate knives and forks on opposite sides of a plate. If relations can be classified, then they must also allow ‘isa’ links, just like ordinary concepts, so the easiest conclusion is that they are a special kind of concept: relational concepts. The distinctive characteristic of a relational concept is that it has two elementary relations: ‘argument’ and ‘value’, bringing the total of elementary relations to three: argument, value and isa. Binding and quantity Two further elementary relations are relevant to node creation. Suppose I see an object in the sky, and wonder what it is. I start by creating a node for it, which we may call N. But this node, like every other node, is the meeting point for a set of relations to other nodes, so it has links not only to all the known properties (its location, its size, its colour) but also to two ‘logical’ properties: its classification and its quantity. Its classification is simply an ‘isa’ link to to an unknown concept, for which the obvious notation is ‘?’. We can be sure that this isa link exists because that is what it means to wonder what N is. But ‘?’ has the special property of needing to be bound to some other concept, its permanent model. The search for this model is driven by activation spreading through the network from N’s known properties, so the ‘best-fit principle’ (Winograd 1976) chooses the most active node as the winner, and binds N to it. But this means that all, or at least most, of N’s properties must match those of its eventual model. This is where the quantity relation applies. The quantity of N is simply ‘1’ – i.e. it exists as an entity. Like its other known properties, this needs to be compatible with the properties of the model, so ‘?’ can’t bind to a node whose quantity doesn’t unify with 1. It is the quantity relation that allows Word Grammar to distinguish obligatory, optional and impossible values. Defaults As in other chapters of this book, the analysis assumes default inheritance as the underlying logic – in other words, generalisations that allow exceptions. Default inheritance is widely accepted in AI (Luger and Stubblefield 1993), and the same logic explains the ‘prototype’ concepts of cognitive psychology (Rosch 1978), so non-linguistic examples are plentiful: penguins as exceptional birds, ash-trays as marginal furniture, and so on. Critics have noted a number of potential weaknesses in the logic such as its ‘non-monotonicity’ (meaning that any inference in a series of dedunctions is in danger of being overturned later), but all of these weaknesses vanish if we make one simple assumption: that inheritance is part of the process of creating and enriching new nodes, and only applies at that point (Hudson 2010, 43). Landmarks One obvious fact about a network is that it has no left-right dimension, so it forces us to treat linear ordering in terms of relations. Fortunately, Cognitive Grammar offers a name for spatial and temporal relations: ‘landmark’ (Langacker 2007), which links a ‘trajector’ to the entity from which it takes its position. For example, in thinking about my nose I take my face as its landmark, and similarly I know that our house is in London, so London is its landmark. Since ‘landmark’ is a relational concept, it can be further subclassified into ‘before’ and ‘after’, which will provide the basis for specifying the order of morphemes or words in a linguistic structure (Hudson 2007, 130). This list defines the ‘mental apparatus’ that Word Grammar assumes to be available for linguistic analysis. Every item seems to be part of general cognition, so the challenge is to apply the apparatus to complex linguistic data, such as the French pronoun system. 3 The notation However, before embarking on this analysis I need to introduce the Word Grammar notation for networks. Inevitably, network analysis requires network diagrams. We start with Figure 1. meaning purrer purring cat CAT Smudge Figure 1: A network for 'cat' The rectangles contain names for non-relational concepts (or ‘entities’) while the ellipses contain the names for relations. The small triangle signals the ‘isa’ relation iconically, with its broad base on the supercategory and its narrow apex linked (by a dotted line) to the example. ‘CAT’ is a lexeme, while the other labels have their ordinary meanings. In words, Smudge isa cat, a cat (typically) purrs (i.e. it is the ‘purrer’ in the typical act of purring), and the concept ‘cat’ is the meaning of the lexeme CAT. Figure 2 shows how default inheritance works. It assumes a ‘token’, an object that I have seen and classified as a penguin. The only additional notation is the ‘#’ label, short for ‘quantity’, and the fact that boxes may have no name. (Indeed, one of the consequences of the network notion described above is that labels are irrelevant, because a node’s links to other nodes exhaust its properties.) When a box has no name, it is notationally convenient to put the quantity label into the box, thereby saving one box and one link; so a box containing, say, ‘0’ is equivalent to an empty box with a ‘#’ link to another box containing ‘0’. According to this diagram, then, my token isa penguin, which isa bird; but whereas the typical bird (‘bird’) may fly (is the flier in more than 0 occurrences of flying), penguins cannot. So if my token had been flying, the quantity of its flying would have been 1, and its classification as a penguin would at least have been problematic. (If it looked like a penguin and was in the right location for a penguin and behaved otherwise like a penguin, then maybe I have discovered a new variety of penguin that flies.) This diagram also shows how relational concepts are linked, like entities, in an isa hierarchy. # flier bird flying penguin 0 token 0 >0 Figure 2: Penguins as an exception in WG notation Finally, we have two diagrams which apply this notation to language, starting with an example from morphology, Figure 3. This network fragment does not introduce any new notation, but shows a slightly higher degree of complexity. In prose, the lexeme BE isa verb, and so is the category ‘present’. (This is obviously a simplification.) By default, a present-tense verb has an inflected form or ‘infl’ (called ‘fif’ for ‘fully inflected form’ in earlier Word Grammar work) which inherits all the properties of its base, so given that the base of BE is the morpheme {be}, we might expect a token of [BE, present] to be {be}, but exceptionally it is {are}, so this is the infl that the token inherits. verb base base {be} BE present infl [BE, present] {are} token Figure 3: By default, a verb’s present form is its base, but BE is an exception The next diagram shows how the ‘landmark’ relation can be combined with default inheritance. As mentioned earlier, once we recognise ‘landmark’ as a relation, we can make it more precise by distinguishing two sub-cases: ‘before’ and ‘after’; for example, if my birthday is before Christmas, Christmas is its landmark but more precisely Christmas is its ‘before’. Now suppose we want to use these relations to define the order of a series of objects which can occur together in random combinations but a fixed order – in other words, a series such as the letters of the alphabet or, indeed, a morphological template. What we can’t do is simply to link adjacent pairs; for instance, to define the order A B C D, we cannot simply show B as the before of A, C as the before of B and D as the before of C. The trouble with this analysis is that, as it stands, it doesn’t generalise to partial strings such as A C. To solve this problem we could ‘overspecify’ by listing every possible pair: A before B, A before C, A before D, and so on. But although this solution would work, it would miss the simple point that the relations are transitive: for any items x, y and z, if x before y and y before z then x before z. A transitive analysis is shown in Figure 4. This figure presents the same analysis twice. On the left side, the letters A, B, C and D are shown in the desired order, in contrast with the diagram on the right, where they are in random order. The point of this diagram is that the two diagrams are exactly equivalent, because all that counts in a network is the relations, and not the left-right orientation. In prose, C and D belong to a category ‘cd’, which isa ‘bcd’ along with B. These isa relations guarantee transitivity, because if A is before bcd, it is necessarily before all of them. A B C D B C D A before cd cd before bcd bcd Figure 4: Landmarks in transitive ordering The last example illustrates a further consequence of the cognitive principles, which is that we are trying to model the mind of individual people. Since our minds reflect our experience of life and (in language) of usage, and since different people inevitably have different experiences and may construe similar experiences in different ways, we may expect considerable variation from one mind to another even within a homogeneous community. This variation applies to the ordering of A, B, C and D because orders can be analysed either in terms of ‘before’ or in terms of ‘after’, with exactly the same result. It would be very hard to find evidence for one analysis rather than the other, so any analysis is simply a currently untestable hypothesis that some minds have this structure, while others may have the alternative and others again may even have both, or some other combination. 4 The architecture of language If language really is a sub-network within the super-network of cognition, can we recognise any kind of ‘architectural’ structure comparable with the traditional ‘levels’ of grammar, semantics, phonology and the lexicon (Jackendoff 1997)? One of the points on which all cognitive theories agree is that there is no cognitive basis for the traditional distinction between ‘the lexicon’ and ‘the grammar’. Rather, we have a continuum of generality with very general categories such as ‘word’ at one end and very specific ones such as ‘the word KICK as used in kick the bucket’ at the other end, and no formal boundary between the two. This can be seen in the fragment of morphology presented above in Figure 3. In this diagram, both the lexeme BE and ‘present’ isa ‘verb’, although traditionally the lexeme would belong in the lexicon and the inflectional category in the grammar. Moreover, the exceptional realization {are} for [BE, present] has just the same status (and formal structure) as the default realization of ‘present’ which it overrides. Even more strikingly, the same diagram even includes a transient token of [BE, present], with its inherited structure which (precisely because it is inherited) has the same formal structure as the type from which it inherits. In this analysis, then, there is a clear hierarchy of generality from ‘grammatical’ categories through ‘lexical’ categories down to the least general categories of all, the tokens; but there are no natural boundaries in this hierarchy which might justify a division between the lexicon and the grammar. In this respect, cognitive theories such as Word Grammar are sharply at odds with more traditional theories, whether transformational or not. In relation to morphology in general, and clitics in particular, this conclusion rules out any ‘lexicalist’ analysis, whether generative or not, in which morphology and cliticization are handled ‘in the lexicon’, prior to insertion into a structure generated by ‘the grammar’ (Scalise and Guevara 2005; Miller and Sag 1997). On the other hand, a network can distinguish the traditional ‘levels of analysis’ by means of classified relations, just as in an attribute-value matrix. Consider a conservative analysis of words in which a word has a meaning and a realization; for example, the lexeme CAT (a word) means ‘cat’ (an animal) and is realized by /kat/ (a sound-sequence). The only part of this analysisis which is at all controversial is the claim that CAT is autonomous of its meaning and its realization, in contrast with the claim in Cognitive Grammar that words are merely Saussurean signs which relate meanings directly to sounds (Langacker 2007). The conservative view distinguishes three ‘levels’ of linguistic analysis: semantics, grammar and phonology (or graphology), which are clear consequences of the general cognitive process of ‘representational redescription’ (Karmiloff-Smith 1992) whereby children build increasingly abstract representations of their experience. (And of course, phonology and graphology are in turn redescriptions of less abstract levels such as acoustic and articulatory phonetics; in a network approach it makes no sense at all to debate whether or not these are ‘truly’ levels of language structure, just as it makes no sense to ask similar questions about the status of semantics.) Each level is distinguished by: a vocabulary of elementary units of a particular kind (e.g. words for syntax, phonological segments for phonology) a particular relation to neighbouring levels (e.g. ‘meaning’ and ‘realization’ relating words to meanings and realizing forms) a vocabulary of categories, relations and structural types for organising elements at that level. Similar distinctions of level apply across cognition, as in the familiar levels of physics, chemistry, biology and psychology, each of which is a more abstract redescription of the level below it. What is more controversial in linguistics is the status of morphology. Is morphology a separate level of representation, mediating between the words of syntax and the segments of phonology? Or do syntax and phonology meet directly, either by means of processes that relate words directly to phonology (Anderson 1992), or by syntactic rules which organise morphemes inside words (Halle and Marantz 1993)? For instance, is the internal structure of, say, dogs simply /dogz/, without any morphological division into root and suffix, or a combination of two morphemes, {dog}+{Z}; and in the latter case, is it the rules of syntax that are responsible for this combination or do we need a separate level of morphology with its own combinatory principles and vocabulary of elements? The status of morphology thus breaks down into two questions: Are morphemes psychologically real? Are morphemes combined into words by the same mental principles or rules that combine words with one another? On these questions, Word Grammar takes the rather conservative view that morphemes are real and are distinct from words, so they are meaningless ‘morphomes’ (Aronoff 1994); and that they are handled by a separate set of rules, so there really is a separate level of morphology. But it is important to keep the two questions separate. First, then, are morphemes psychologically real? Here too the cognitive assumptions of (2) are relevant. Recycling in processing. The general principle in (3) that ‘the rich get richer’ means that we try to ‘recycle’ existing forms in interpreting word tokens, even when the fit isn’t perfect. For instance, when we hear the word fearing we recognise the form /fiər/ as an example of /fiə/, the realization of fear, even though (in a non-rhotic accent) the two are not phonologically identical and the first is not even a complete syllable (or any other kind of phonological unit) in the larger structure /fiə+rɪŋ/. So the morpheme {fear} must be distinct from its phonological realizations /fiə/ and /fiər/. Concept-creation in learning. When we learned a new word as children we must have identified its form as a unit; so when we learned WAIT we identified /weɪt/ as its form, linked to a particular meaning. But given the network view of concepts, this linkage immediately creates a new concept, which is necessarily distinct from any purely phonological concept such as a stored syllable; so even if we stored every syllable as a syllable, the syllable /weɪt/, without a semantic link, must be distinct from the morpheme {wait}, which also has a semantic link. Recycling in learning. Our learning was also guided by the recycling principle, so we were constantly on the lookout for partial similarities, including similarities between monomorphemic words such as WAIT and complex words such as WAITER. But every similarity between two words requires an extra network link, not to mention the links to morpheme classes such as ‘affix’ or ‘base-form’, all of which reinforces the difference between purely phonological units and morphemes. For the record, it can be argued that we do much the same in semantics when we build a familiar meaning into the definition of a more complex one (Hudson and Holmes 2000). Recycling in folk etymology. Ordinary people reanalyse complex words in terms of existing words, regardless of the meaning. For instance, when hamburger (originally, a sausage from Hamburg) was adopted in English, its first syllable was identified with the form of ham, even though the sausage didn't actually contain ham, leading eventually to creations such as cheeseburger. In short, {ham} is a morpheme shared by both ham and hamburger rather than just a bit of phonology. Priming: psychological experiments show that phonological priming (e.g. nurse – verse) dies out much faster than morphological priming (e.g. contain – retain) (Frost and others 2000). This shows that morphological and phonological patterns must be cognitively distinct. These cognitive arguments support the view that morphological structure (including morphemes) is psychologically real. This means that we must know not only the lexemes of our language, but also its morphemes. And that in turn is at least compatible with the idea that we recognise morphology as a distinct, autonomous, level of structure. The second question is whether syntax is responsible for morphological structure. Once again, the cognitive arguments are compelling. If morphemes really are distinct from words, so that words and morphemes constitute two separate vocabularies, then it obviously follows that they must be classified as different, with ‘word’ and ‘morpheme’ as super-categories at the top of two different isa hierarchies. And if these two super-categories are different, then once again they must have different properties so words and morphemes must inherit different properties. For example, we may assume that words have a ‘meaning’ relation which morphemes don’t have, while morphemes are realized by phonology whereas words are realized by morphology. These differences are enough to guarantee that different principles or rules govern the ways that words and morphemes combine. Fortunately, there is also plenty of empirical evidence that this is indeed the case – all the evidence that supports the familiar arguments for Word and Paradigm morphology (Robins 1959) and its more recent manifestations in inferential and realizational models (Stump 2001). For example, whereas free order is common in syntax, it is vanishingly rare in morphology (with an interesting exception in French clitics which I explore below); and whereas ordering by template is generally accepted in morphology, it is unknown in syntax. And of course there are well-attested cases where the morphological structure of a sentence is out of step with its syntactic structure (Sadock 1991). The empirical evidence therefore supports the a priori argument from general cognition, so Word Grammar is one of the many theories of language which assumes that morphology constitutes an autonomous level of analysis, as shown in Figure 5. concept 'cat' meaning word CAT realization morpheme {cat} realization syllable /kæt/ Figure 5: four levels: semantics, syntax, morphology, phonology One important consequence of this conclusion is that the units of morphology and syntax differ in abstraction rather than in size. As the figure’s cat example shows, the word CAT is realized by the morpheme {cat}, both of which correspond to the same amount of phonology, so they both have the same length. The same is true of the plural cats, where the syntactic word [CAT, plural] is realized by {cats} – a ‘wordform’ rather than a single morpheme. The distinction between words and wordforms is important in comparison with non-realizational theories where the whole of which a morpheme is a part is a word rather than a wordform, but it also underlines the contrast between morphology and syntax because Word Grammar, like other dependency-based theories, claims that words are related by dependency relations rather than by part-whole constituency relations. Thus one of the differences between syntax and morphology is the basic combinatory relationship – partwhole in morphology, but dependency in syntax (Hudson forthcoming). The ‘architecture’ of Figure 5 is a statement of typical patterns: a typical word has a meaning and is realized by a morpheme, a typical morpheme is realized by a syllable and a typical syllable realizes a morpheme. But alongside these typical arrangements there are many exceptions, all of which can be accommodated thanks to default inheritance. Most obviously, words, morphemes and syllables are often not in a 1:1 relation, but even the ‘levels’ allow exceptions; for instance, phonesthemes seem to relate directly to meaning, as do the tunes of intonation.) 5 Default morphology Following the assumptions of Word Grammar, therefore, our mental representation of an utterance includes an autonomous morphological structure, consisting of morphemes and larger morphological units, and linked by realization to the neighbouring levels of syntax and phonology (or graphology). Since the stored grammar is nothing but a network, it is purely declarative and cannot contain procedural rules such as ‘Add {Z} to the base’, though it can of course include network structures that are equivalent. Mental procedures do of course exist, but they are the domaingeneral processes of node-building and node-enrichment, including the process of inheritance. It is these procedures that allow the static network to apply dynamically to particular tokens, and that allow defaults to be overridden. I have already introduced the basic principles of inflectional morphology through the earlier example Figure 3, which showed how {are} overrides the default value for ‘infl’, the inflected form of a word. As this example showed, all the complexities of morphology lie in the relations (e.g. ‘base’, ‘infl’); so each inflectable word inherits its base from the lexeme and its infl from the inflectional category. In more complex morphology, the number of relations involved increases proportionately. For instance, English morphology recognises a ‘z-form’ relation, which links the base to a form which is used both in plural nouns and in singular verbs; the morphology of z-forms is shown in Figure 6. In prose, a word has both a base (defined by its lexeme) and a z-form, which consists of two parts (labelled ‘0’ and ‘+’, as explained below): the first part inherits from the word’s base, while the second part inherits from the morpheme {Z}. The right-hand part of the figure shows an elementary classification of forms, dividing them first into base-forms (simple or complex) and affixes. A typical word has a base-form as its base. No doubt the diagram could be improved, and it could certainly be extended, but the main point is that (apart from the term ‘word’) the diagram is pure morphology. It should be easy to see how this kind of analysis can be extended to cover more complicated morphological patterns such as those of French inflected verbs; for instance, finirons, ‘(we) will finish’, is the ons-form of the r-form of the verb FINIR (whose base is just {fin}). form affix base-form base e word {Z} complex simple 0 z-form + Figure 6: The morphology of z-forms One extra fact which will prove important in the discussion of French pronouns is that affixes inherit a general property of needing a ‘mother’, a complex form of which the affix is a part and which also contains a base-form. The traditional classification of affixes as prefixes, suffixes and infixes determines their position relative to their landmark, the base-form, which is shown in these diagrams by labelling the ‘part’ relation as ‘0’ (for the base) or ‘+’ (for a suffix, i.e. a unit that follows the base). This notation for showing simply that some affix follows the base will play an important part in the analysis of French enclitics (section 8). form affix mother baseform suffix + complex Figure 7: Affixes have a mother Once a morphological structure has been defined in this way, it can be mapped by the morphosyntax onto the categories of syntax and by the morphophonology onto those of phonology. The irregularity of are (instead of the expected be) in Figure 3 already illustrates morphophonology, so we only need an example of morphosyntax, for which we take the plural noun. As can be seen in Figure 8, the morphosyntax is trivial, but the example illustrates the benefits, for users, of separating morphology from syntax. This separation allows morphological patterns to be recycled in different parts of the morphosyntax, explaining the phenomenonon of ‘inflectional polyfunctionality, the systematic use of the same morphology to express distinct but related morphosyntactic content’ (Stump 2014, 73). In the English case, the suffix {Z} is recycled in the paradigms of both nouns and verbs, so that the number of affixes used is smaller than the number of inflectional categories distinguished. noun z-form plural infl Figure 8: Plural nouns have the z-form This elementary introduction to inflectional morphology in Word Grammar provides the foundations needed for the discussion of French pronouns. 6 Clitics The following sections will argue that French pronouns are clitics, so it is important to be clear what this claim means. The term clitic has been defined in many different ways, but all the definitions locate clitics as something between a full word and an affix, with the syntax of a full word but the phonology and rigid position of an affix. But the previous discussion has argued that words and affixes are different kinds of entity, as different as (say) nouns and vowels, so they cannot be located on a continuum with clitics somewhere in between. However, this discussion also lays the ground for a very simple definition: (4) A clitic is a word realized by an affix. Whereas a typical word is realized by a base-form, with or without added affixes, a clitic is exceptional in being realized just by an affix – i.e. in having an affix as its ‘infl’, the form that realizes it and which cannot be inflected any further. Thanks to default inheritance, this exceptional pattern is easy to model, and of course it also explains why clitics combine the meaning and syntax of a whole word with the phonological weakness and inflexible position of an affix. We start with simple clitics (Zwicky 1977) - syntactically normal words, in their normal position, but with reduced pronunciation, as in (5). (5) That’s right. (6) That is right. Example (5) has exactly the same syntactic structure, including the same ordering of all the elements, as its unreduced equivalent in (6), so there can be no doubt that the element written ’s is a separate word – a finite verb, without which the sentence is ungrammatical. But nor can there be any doubt that it is morphologically like an affix, because it has the same allomorphy as the {Z} which we find in plural nouns, singular verbs and possessives (Hudson 2013). If this really is the {Z} morpheme, it is another example of recycling which maximizes the functions of each morpheme. One important element is missing even in the analysis of simple clitics like this. We saw in section 5 that an affix needs a ‘mother’ – a complex form that holds it together with the base-form to which it is attached. Traditionally, clitics ‘lean’ on the word to which they are attached, in just the same way that an affix might be said to ‘lean’ on its base-form. But in both cases this ‘leaning’ is enabled by a larger unit, the affix’s mother. So what is the mother for the affix in (5)? It must be {that’s}, a morphological complex specially created to accommodate the morphemes {that} and {Z}. And this, in turn, must be an example of a special kind of complex which we can call a ‘hostform’ (building on the terminology in which the clitic ‘leans’ on its ‘host’). The general network for clitics is show in Figure 9: a word’s ‘infl’ (i.e. final form, including any inflections) is normally a word-form, but exceptionally a clitic’s is an affix. Like any other affix, this affix needs a mother, which is an otherwise undefined unit called a ‘hostform’ which is also mother to the realization of some other word, the clitic’s ‘host’. The converse of the ‘mother’ relation is ‘part’, which may be either the first or second part, labelled once again ‘0’ and ‘+’. infl word wordform form infl mother 0 host hostform mother clitic infl + affix \ Figure 9: A grammar for simple clitics Given this grammar, Figure 10 should be largely self-explanatory as an analysis of that’s in That’s right. The fact that the verb is a clitic is shown in its classification as [BE, pres, sing, clitic], showing that it isa ‘clitic’ as well as the three other categories. Strictly speaking, these labels belong to stored types, and the word tokens in this example should be distinguished from the types of which they are examples (Hudson 2015), but for the purposes of this chapter the distinction is unimportant. However it is important to emphasise that the hostform labeled {that’s} is not a stored unit, unlike the morphemes {that} and {Z}. The label on the hostform is simply a concatenation of the labels on its parts. host THAT [BE, pres, sing, clitic] infl infl {that} {Z} mother 0 mother {that’s} +1 Figure 10: A simple clitic in That's right. It is important to note that the cliticized auxiliary verb is syntactically the head of the entire sentence, and its host word is subordinate to it (unlike the clitic patterns of Middle English, where we find ‘t is rather than it’s). This is the reverse of the situation with French pronouns, where the clitic is syntactically subordinate and functionally not dissimilar from inflectional affixes. English cliticized auxiliary verbs are important because they have nothing at all in common with inflectional affixes, so they establish the general principle that ‘clitic’ is a real category in grammatical theory, and that at least some putative clitics really are clitics, not inflectional affixes. The question for the next section is not whether clitics exist, but where the boundary lies between clitics and inflectional affixes. What this section has achieved is the beginnings of an analysis of clitics, based on the idea of clitics as syntactic words with an irregular morphological realization as affixes, combined with the new ‘hostform’ to act as mother to this affix and to the word on which it ‘leans’. 7 French pronouns as clitics French unstressed pronouns are found in examples like (7), in contrast with non-pronominal equivalents such as (8). (7) Je te le donnerai I to.you it will.give ‘I will give it to you.’ (8) Jean donnera le cadeau à Marie. John will.give the present to Mary. The challenge is to explain why the object pronouns te and le stand before the verb when their phrasal equivalents stand after it. Moreover, the relative order of the pronouns is absolutely fixed: te le, never *le te. In contrast, when the objects are both phrases, either order is possible, depending on the elements’ relative ‘weight’ so (8) and (9) are both possible. (9) Jean donnera à Marie un cadeau merveilleux. John will.give to Mary a present marvelous ‘John will give Mary a marvelous present.’ However, there is one pattern in which the object pronouns follow the verb: when the verb is imperative and affirmative, as in (10) and (11). (10) (11) Donne-le-moi! give it to.me ‘Give it me’ Donne-moi-le! give to.me it ‘Give me it’ Prescriptive grammars of standard French proscribe the pattern in (11), but it is reported to be common in spoken French, at least in Paris (Hawkins and Towell 2001, 69), and more generally, postverb pairs of pronouns can almost always be used in either order (with one interesting exception discussed below). The first question, therefore, is whether examples like (7), (10) and (11) really contain clitics. The alternative is that the affixes realize inflectional contrasts, in just the same way as the suffixes which indicate tense and subject-agreement inflection. The inflectional analysis has been defended in a number of generative analyses (reviewed and rejected in De Cat 2005), and is particularly popular in the HPSG tradition (Miller and Sag 1997; Crysmann and Bonami 2015), so it needs to be addressed seriously. The debate is sometimes cast in terms of ‘syntactic’ versus ‘morphological’ analyses, but even if clitics are syntactic words they are also linked by morphology to their host, so the question is simply whether the affixes concerned realize separate syntactic words (as clitics), or inflectional categories on the verb (as inflectional affixes). The following arguments all support the clitic analysis. In order not to presuppose the conclusion too strongly, I shall refer to the putative pronouns merely as ‘pronoun-affixes’, since most people agree that in some sense they are affixes. The first argument is cognitive. Imagine a French child who encounters the following pair of very ordinary sentences: (12) Mange le fromage. eat (13) the cheese Mange-le. eat it The inflectional analysis assumes that the child sees no similarity between these examples beyond the verb mange. But surely this is implausible. Any theory of learning which allows learners to spot patterns must allow the learner to notice the repeated le. But the determiner le in (12) is definitely a syntactic word (though it too may be a clitic within the noun phrase), so why should the child not assume the same for the pronoun le? Moreover, this identification is strongly supported by other examples, which show that le is associated in both cases with masculine singular nouns, in contrast with la for feminine singular and les for any plurals; and in all cases, this word signals definiteness. The choice among le, la and les is made on exactly the same basis in each case, so it is fair to assume that a learner will identify them, choosing a clitic analysis rather than the inflectional analysis. The same argument can be run in reverse: if le is directly dependent on mange in (13), then why not also in (12)? In this case the argument supports the DP-style analysis in which le is the head of le fromage, just as (arguably) the is the head of the cheese (Hudson 1990, 268–276). A second argument is based on typology. As we have seen, the pronoun-affixes can occur either before or after the verb, and when they follow the verb there is almost complete free variation. As an example of inflectional affixes, this would very unusual. Although free word order is common, free morpheme order is rare (Moravcsik 2012, 173). Admittedly this typological claim has been disputed (Crysmann and Bonami 2015), but one of the key cases cited is that of the French pronoun affixes, so there is some doubt regarding the reliability of the remaining cases. The fact remains that most affixes, in most languages, are rigidly tied to just one position within the structure of their word, so any analysis which assumes mobile affixes requires extremely strong supporting evidence. A third argument is based on semantics. The pronoun-affixes at least appear to have referential meanings, just like the meanings of the pronouns that translate them in other languages such as English. Moreover, the quantifier tous, ‘all’, can ‘float’ off any plural affix pronoun, just as it can from a wh-pronoun. Miller and Sag quote the following examples (Miller and Sag 1997, 627): (14) Marie a vu tous les livres. 'Marie saw all the books.' Mary has seen all the books (15) (16) (17) (18) *Marie a tous vu les livres. Marie les a vus tous. 'Marie saw all of them.' Marie les a tous vus. 'Marie saw all of them.' ... les livres que Marie a vus tous... ... the books which Mary has seen all... ‘the books all of which Mary has seen’ (19) ... les livres que Marie a tous vus ... The obvious conclusion from the distribution of tous is that the pronoun-affixes have the same status as wh-pronouns, so if the latter are syntactic words, the same must be true of the former. The fourth argument is based on syntax. The inflectional analysis is based on the assumption that each pronoun-affix removes some element from the verb’s valency (i.e. from the list of complements and the subject). The inflectional analysis works smoothly because the valency is one of the verb’s properties, comparable with its tense and subject agreement; but one of the pronounforms is y, meaning ‘there, to it, at it’. (20) Jean y a écrit son nom. John on.it has written his name This is seriously problematic for the inflectional analysis because y would not normally qualify as a complement, so some kind of special arrangement would need to made to accommodate these nonarguments in the argument list (Miller and Sag 1997, 597). In contrast, the clitic analysis can accommodate adjuncts as easily as arguments. The fifth argument is similar to the two previous arguments: like y, the pronoun-affix en, which means ‘of it, from it’, need not be a complement or subject of the verb to which it is attached; but like the object pronouns, it behaves in a very similar way to a relative pronoun, in this case dont ‘of which’ (Miller and Sag 1997, 612–623). The argument involves examples like the following: (21) Marie en connaît la fin. Mary of.it knows the end ‘Mary knows the end of it.’ (22) La fin en est désagréable. the end of.it is unpleasant In these examples, en seems to be a complement of fin, ‘end’ rather than a direct dependent of the verb. This is clearly not expected in the inflectional analysis, but worse still, the noun phrase to which en belongs need not even be a complement of the host verb, as can be seen in the next example: (23) On en peindra le bout du pied gauche. one of.it will.paint the end of.the foot left. ‘One will paint the end of its left foot.’ However, as Miller and Sag point out, the constraints on en are exactly the same as those on the relative pronoun dont, ‘of which’, as in (24) to (26): (24) (25) (26) ... la seule histoire dont Marie connaît la fin ... ... the only story of.which Mary knows the end ... ... une histoire dont la fin est désagréable ... ... a story of.which the end is unpleasant ... ... une statue dont on peindra le bout du pied gauche ... ... a statue of.which one will.paint the end of.the foot left ... Once again, the obvious conclusion is that en has the same syntactic status as dont, so that the same generalisations can apply to them both. But this implies that en, like dont, is a syntactic word – as in the clitic analysis, but not in the inflectional analysis. The last argument is based on morphosyntax, and involves not only the pronoun-affixes y and en, but also the object pronouns le, la and les (‘him’, ‘her’, ‘them’) whose similarities to the definite articles were the basis of the first argument. The pronoun-affix y has the meanings expected with the preposition À, which usually translates as ‘to’ or ‘at’; and similarly en is very similar to the preposition DE. In some sense, therefore, it is tempting to see these two prepositions ‘in’ the pronoun-affixes. But the same two prepositions are also involved in a morphological rule which applies when they combine with a definite article: where we expect de le and à le we find du and au, and the expected de les and à les are replaced by des and aux. Almost everyone agrees that these complications leave the syntax unaffected, so that du is simply an irregular morphological realization of the two words DE LE (i.e. DE + the definite, masculine, singular article). As mentioned earlier, this pattern suggests that the determiner is directly linked to de, thereby supporting the DP-style analysis with determiners as heads (Hudson 1990, 272). But it also strengthens the temptation to find DE in en and À in y, and even suggests an analysis in which each of these pronoun-affixes is an irregular realization of the preposition plus a gender- and number-neutral pronoun. Admittedly the wordform correspondence is even more irregular than for du, but y is no less regular than au, given their respective pronunciations as [i] and [o]. The same analysis could even be extended to the relative pronoun dont mentioned above, as an irregular realization of DE + relative pronoun. At present these analyses are merely speculative, but none of them could be reconciled with the inflectional analysis of y and en, whereas they are all compatible with a clitic analysis. In conclusion, therefore, the overall evidence seems to give overwhelming support for the traditional analysis of French pronoun-affixes as clitics – as syntactic words which are realized by affixes. This is the analysis that will be assumed in the remaining sections. 8 Enclitics as simple clitics We now move towards a formal analysis of French clitic pronouns, building on the theoretical framework already established for simple clitics in English. A simple clitic such as the ‘s in That’s right is a syntactic word – in this case, exactly the same syntactic word as the verb in That is right, except that its classification includes ‘clitic’, so we can call it [BE, 3sg, clitic]. Being a clitic, its base (and infl) is an affix rather than the expected ‘base-form’, but any affix needs a ‘mother’, a word within which it is a part. This mother-word cannot be the ‘host’, the word on which the clitic is traditionally said to ‘lean’, because this does not provide a suitable morphological home for the affix. Consequently, the clitic carries its own ‘hostform’, a morphological unit which does provide the necessary home for the clitic affix and which also has a vacancy for another word’s morphology – i.e. for the host-word. This is the analysis that was shown in Figure 9. A French example corresponding to the English simple clitics is the definite article, which we can call simply [DEF], to be clear that this is a syntactic word, in contrast with its morphological realizations {le}, {la}, {les}, signalling gender and number, and {l’}, used in the singular before a vowel. This qualifies as a proclitic because it attaches phonologically to the next word, but like the English auxiliaries, the only restrictions on the next word are those that follow from the ordinary rules of syntax. Take an example like (27). (27) le grand livre the big book Here the word [DEF, masc] is realized by {le}, which, as a clitic, is part of a hostword, with the next word, [GRAND], as its host and the latter’s realization as the other part of the hostword. The ordinary rules of syntax are responsible for the existence and position of grand so it happens to be the next word after le, and therefore to qualify as the latter’s host. The example is deliberately chosen, of course, because of the similarities noted earlier between this clitic and the clitic pronouns meaning ‘him’, ‘her’ and ‘them’. The clitic analysis of pronouns allows a much more revealing analysis of these similarities. The main aim of this section is to consider French pronouns when they are enclitics, which only happens with affirmative imperative verbs. Because of this limited distribution, enclitics are usually treated as an exception to the normal pattern of proclitics, but this approach misses a rather important fact about enclitics: that they are actually simple clitics because their ordering follows the ordinary rules of syntax for phrasal dependents of the verb. As explained earlier, if two enclitics combine, their order is almost always free, just as it is for phrasal dependents. The relevant examples are (10) and (11), repeated below: (28) (29) Donne-le-moi! give it to.me Donne-moi-le! give to.me it According to a reviewer, the only exception to this general freedom is that le, la, les (him, her, them) must not follow lui, leur (to him/her, to them). (30) (31) Donne-le-lui! *Donne-lui-le! This exception can easily be handled by a ‘landmark’ link from the indirect object pronoun lui to the direct object le, just like the one which positions them in the opposite order in English examples like (32)and (33) (which, incidentally, are overridden for pronouns, as in Give it me!). (32) (33) *Give good marks your students! Give your students good marks! This exception will turn up again in the ordering of proclitics. Otherwise, enclitics follow the same relative ordering as phrases, except, of course, that they cannot be separated from the host verb by an adjunct such as bien, ‘well’: (34) Mange bien le fromage! eat (35) (36) well the cheese Mange le bien! *Mange bien le! If enclitics really are simple clitics (with this one exception), there is no need for a template to position them relative to one another. All they need is a hostform to glue them morphologically onto each other and onto the host verb. Moreover, there is no ‘clitic climbing’ from imperatives, so the host verb is easy to identify, as the verb on which the pronouns depend. (The apparently exceptional pronoun en as in Mange-en beaucoup! ‘Eat a lot of it’ will be discussed in section 10.) In short, the grammar for French enclitics is not much more complicated than that for English cliticized auxiliary verbs. The main difference is that, whereas the English hostform could accommodate any base-form, the French one selects a particular kind of host, an affirmative imperative verb. This selection implies a relation ‘hostform’ (abbreviated to ‘hf’ in diagrams) between the host verb [MANGE, imper] and the hostform {mange-le}. Since the clitic is also part of this same hostform, we can assume the same relation between clitic and hostform. This relation is additional to the relations already listed, so in mange-le, ‘eat it’, for example, we have the following relations: hostform (hf): the hostform {mange-le} is the hf of the word [MANGE, imper] and also of the word [LE, masc]. host: the word [MANGE, imper] is the host of the word [LE, masc]. infl: the base-form {mange} is the infl of the word [MANGE, imper]. infl: the affix {le} is the infl of the word [LE, masc]. mother: the hostform {mange-le} is the mother of both the base-form {mange} and the affix {le}. 0: {mange} is the ‘0’ (in this case, the first part) of {mange-le}. +: {le} is the ‘+’ (second part) of {mange-le}. The cognitive assumptions (2) mean that there is no limit to the number of ad hoc relations that can be created (as we do all the time in the social arena), but in any case each of these relations plays a role in the grammar, so they can all be justified. They are all included in Figure 11, which is laid out so as to be as easily comparable as possible with Figure 10 for the English that’s in That’s right. It can be seen that the highlighted ‘hostform’ link from the syntactic verb to the hostform is the only extra relation. host [LE, masc] [MANGE, imper] infl infl hf {mange} hf {le} mother 0 {mange-le} mother + Figure 11: The structure of Mange-le! Another obvious difference between French enclitics and English clitic auxiliaries is that French allows multiple enclitics hosted by the same verb. This means that the French hostform accommodates more than one clitic, and is equivalent to the ‘clitic cluster’ of other analyses. If, as I have argued, these clitics are in fact simple clitics, occupying the positions they are regularly assigned by the syntax, then the analysis need not restrict the order of the cltics (except for the one restriction noted earlier, to which we return below). But there are systematic restrictions on clitic combinations which go beyond anything found in French syntax. The clitics fall into four groups, with the general restriction that members of the same group may not combine with each other, regardless of meaning and syntax. The groups are listed in Table 1. Table 1: French clitic pronoun groups group A A1 me te se nous vous A2 lui leur me you himself/herself/themselves us you group B le him la her les them group C y, ‘to it, at it’ group D en, ‘from it’ to him/her to them The cooccurrence bans are quite rigid, ruling out sentences which would be semantically and syntactically perfect such as (37), contrasting with the syntactically similar, but non-clitic, (38). (37) *Présentez-me-lui. introduce me to.her (38) Présentez mon ami à votre soeur. introduce my friend to your sister It is true that ‘ethical datives’ break these restrictions, as in the following examples (Jouitteau and Rezac 2008): (39) Regarde te me nous donc ça! Look (40) you me us Prends te c’mon that “C’mon, look at that!” moi donc ce panier, ça me débarrassera toujours. take you me c’mon this basket it me will.relieve (of it) anyway “C’mon, take this basket for me, that will at least lighten my load.” However, such examples are distinct in other ways as well so, with regret, I shall have to ignore them. Returning to the mainstream clitics, we need a mechanism for rationing the clitics in any hostform to one from each group. This is easily achieved by distinguishing four parts (other than the host word), and assigning each group to one part. So we assign group A to ‘part A’, and so on. The relevant part of the grammar is Figure 12. The label ‘0/1’ inside a box simply shows optionality – either 0 or 1 (but not more than one); this notational trick was introduced in the explanation of Figure 2. host clitic group A infl group B infl infl group C group D infl infl hf hf 0/1 1 A 0 0/1 B 0/1 0/1 C D enclitic hostform Figure 12: A grammar for multiple enclitics As noted previously, the order of enclitics is free within the hostform, so it should be remembered that the labels ‘A’, ‘B’ and so on refer only to the clitic classification, and not at all to the order in which they occur. However, we still have to deal with the one, exceptional, restriction on the order of the clitics, which we can now generalise in terms of clitic classes: group A2 never precedes group B. For example, donne-le-lui is possible, but not *donne-lui-le. This restriction is easily stated in terms of a ‘landmark’ relation between the clitic forms, without affecting the syntax. Figure 13 says that a group A2 affix follows a group B affix when they are both part of the same hostform. Notice that the landmark relation (‘after’) has no implications for existence, so the grammar does not imply that a group A2 affix needs a group B affix, or vice versa. clitic group A group B group A2 infl infl after B A hostform Figure 13: The one order rule for enclitics There are a number of morphophonological details that are easily accommodated in this network grammar. For example, the enclitic me has four possible realizations, depending on its context. The ones in (42) and (44) are spoken and casual rather than written. (41) (42) (43) (44) Donne-le-moi. ‘Give it me.’ Donne-moi-le. ‘Give me it.’ Donne-m’en. ‘Give me some.’ Donne-moi-z-en. ‘Give me some.’ However, these details are only marginally relevant to the main thrust of this attempt to understand and formalize the syntax and morphology, so I shall not discuss them further. There is one further detail which goes beyond this chapter: the fact that en, ‘of it’, may appear to be ‘raised’ from inside a noun phrase, as in (21) to (23) (e.g. Marie en connaît la fin. ‘Mary knows the end of it’). The same pattern is of course found in enclitics, but the earlier discussion showed that a very similar pattern is found with the relative pronoun dont, as in examples (24) to (26), so I assume that further research will find a non-raising analysis for both enclitics and proclitics. This completes the grammar of enclitics What we have achieved in this section is to extend the grammar for English simple clitics to accommodate the French enclitics, which are also simple clitics. This extension has involved the addition of one further relation, the ‘hf’ relation between the host word or the clitics and the hostform, and a subclassification both of the clitics and also of the ‘part’ relations between them and the hostform. This grammar will turn out to need further small additions to accommodate the proclitics. 9 Proclitics as special clitics The grammar so far deals with just one cell in the paradigm of French verbs: affirmative imperatives. All other kinds of verb either forbid all clitics (past participles, discussed in the next section) or treat them as proclitics rather than as enclitics. The examples in (41) to (44) contrast with both negative imperatives and non-imperatives: (45) (46) Ne me le donne pas! not to.me it give not “Don’t give it to me!” Tu me le donnes. you to.me it give ‘You give it to me.’ (47) Me le donnes-tu? to.me it give you ‘Do you give it to me?’ In these proclitic examples, there is absolutely no flexibility of position for the pronouns, except of course for the subject pronoun (tu), whose position can be used (albeit rarely in spoken French) to distinguish declarative and interrogative clauses. The most intriguing question, of course, is why affirmative imperatives should be so different from all other verb-forms. Is there a functional explanation for this distinction? Bearing in mind that all functional explanations are mere speculation, the following explanation seems plausible. The clitic clusters on affirmative imperatives are special because they contain neither a subject pronoun nor a negative ne, both of which have good reasons for standing before the verb. For the subject, this is important because its position before or after the verb carries the distinction between declarative and interrogative clauses; and for ne it is important because a pre-verbal ne is normally paired with a post-verbal element such as pas (not), personne (nobody) or jamais (never), so the ne is an important early signal of negation. But the subject and ne are clitics depending on the same verb as the other pronouns, so they all need to be integrated into a single cluster; so in a sense the subject pronoun and ne ‘drag’ the cluster to their preferred position before the verb. the affirmative imperatives have enclitics instead of proclitics. Whatever the merits of this explanation, the fact remains that the pronouns in the enclitic cluster are a subset of those in the proclitic cluster, so it would be reasonable to treat the enclitic cluster as the basic, unmarked, pattern which is further elaborated in the proclitics – or, in default terms, the enclitic hostform is the default, with the proclitic as an exception. But this conclusion is strongly counterintuitive if we think of the verb classes concerned; proclitics are always presented as the general case, with the enclitics of affirmative imperatives as the special exception. Fortunately, the separation of syntax and morphology provides a way to resolve this apparent contradiction: imperatives are exceptional in syntax, but their enclitic clusters are the default in morphology. This is the arrangement shown in Figure 14. hostform verb hf enclitic hf imperative proclitic Figure 14: Proclitics as syntactic default and morphological exception The main difference between proclitics and enclitics (apart from the position of the whole cluster) is that proclitics are special clitics, with a rigid ordering different from that of syntax. The ordering is based on the same clitic groups as enclitics, as listed in Table 1, but of course we now have to include subject pronouns and ne. We discuss inverted subjects, which follow the host verb, at the end of this section. (48) The proclitic template: 1. subject pronouns: je, tu, il, elle, nous, vous, ils, elles 2. negative: ne 3. group A1: me, te, se, nous, vous 4. group B : le, la, les 5. group A2 : lui, leur 6. group C : y 7. group D : en 8. the verb This is a typical example of the kind of ordering often found in morphology which needs an analysis in terms of a template like the hypothetical one in Figure 4. A template is the appropriate apparatus in such cases not just because multiple morphemes can combine, but because their ordering is transitive. For example, subject pronouns precede group A1 whether or not a negative ne is present. But of course a template, in the form of a linear string of slots or cells in a table, is not possible in a network, so we need the network equivalent: a set of positional relations with transitive ordering imposed by a mixture of landmarks and isa relations, as shown in Figure 4. It may not be a coincidence that French also needs a template for its ordinary verb inflections, where multiple suffixes combine with each other in a fixed order as in vendrions, ‘(we) would sell’, consisting of: {vend} ‘sell’ {r} as in vendre, ‘to sell’ {i} as in vendiez, ‘(you) used to sell’ {ons} as in vendons ‘(we) sell’ The point of the example is simply to show that at least three suffixes may combine, suggesting that French speakers use a four-slot template when constructing examples like this. If so, the template for proclitics recycles the template in a different part of the grammar. More generally, we may expect a typological link between template-based special clitics and template-based complex inflectional morphology. Returning to the details of French, therefore, we need a template with eight positional slots for the realizations of the verb, the pronouns and ne, as listed in (48). These slots generally map easily onto the clitic groups established to predict mutual compatibility for enclitics, but there is one interesting exception. As with enclitics, group A reflects compatibility accurately, but, again as with enclitics, it divides into A1 and A2 for ordering, because group A2 (lui, leur) has a special positioning restriction. Even more interestingly, the effect of this restriction is precisely the same as the restriction that applies to enclitics and which is stated in Figure 13: that group A2 (lui/leur) must not precede group B le/la/les. The template accommodates this restriction by providing a separate slot for group A2 after group B, but of course this means that group A pronouns are split between two different slots. In spite of this split, group A still acts as a unified group for compatibility purposes. For example, although me precedes le because it belongs to A1 and lui follows le because it belongs to A2, the sequence *me lui is impossible. Figure 15 shows the grammar for proclitics. It is based on the grammar for enclitics in Figure 12, with the new parts highlighted, so it is easy to see that the enclitics grammar is a subset of the new grammar. The main change, apart from the addition of the subject and negative clitics, is the change of label on the relations at the bottom, from the arbitrary labels ‘A’, ‘B’ and so on, to the numbers. It should be understood that these numerical labels are only meaningful because they are defined by a recursive network of landmark relations like the one in Figure 4. host clitic subj neg ne group A2 infl infl infl group A infl 1 hf -7 -6 0 Figure 15: A grammar for proclitics infl infl 0/1 0/1 0/1 0/1 -3 group B proclitic hostform -4 infl infl 0/1 -5 group D group C 0/1 0/1 -2 -1 hf When this grammar is applied to an example, it gives the structure in Figure 16 for (49), which is displayed so as to make it as easy as possible to compare with the earlier Figure 11 for the much simpler enclitic example Mange-le! Once again, the simpler structure is a subset of the more complex one, and the additions are highlighted. For simplicity, this diagram omits most of the ‘mother’ and ‘hf’ relations as well as the repeated ‘infl’ labels. (49) Je ne le lui donnerai pas.

There remain just two issues: subject inversion, discussed now, and the major issue of clitic climbing, to which the next section is devoted. Subject inversion is needed for written examples such as (50). (50) Le mangeras-tu? it will.eat you ‘Will you eat it?’ However, subject inversion is much more limited than other proclitic patterns. For one thing, it is ‘marginal’ in casual speech (Martineau 2012, 193); and for another, most verbs forbid inversion altogether if the subject is je, ‘I’ (Miller and Sag 1997, 577); for example, although both tu sors and je sors (you/I exit) are possible, only sors-tu is grammatically possible. This curious restriction raises similar issues to those raised by the English *I amn’t gap: why does it exist, and how do children learn that it exists? (Hudson 2000) It calls for a theoretical explanation, but meanwhile we can at least incorporate it into the growing grammar, along with the equally tantalising lexical exceptions such as suis-je, ‘am I?’. The resulting grammar is as shown in Figure 17: exceptionally, inverted verbs have an ‘inverted hostform’, which, exceptionally, has a ‘+1’ part for subject pronouns. Furthermore, a ‘1sg’ subject pronoun (i.e. je, ‘I’) has a hostform whose quantity is ‘0’ – in other words, it has no hostform, so it cannot be inverted; but there is one more exception to an exception: if the inverted verb is suis (the 1sg of ETRE, ‘be’ – not the homophonous suis meaning ‘follow’!) then an inverted hostform is possible after all. host clitic inverted verb ETRE, 1sg 1sg subj +1 hf hf infl hf 0/1 hf 0/1 0 -7 inverted hostform proclitic hostform Figure 17: Inverted subjects The grammar presented so far has concentrated on the morphosyntax of clitic pronouns, with very little discussion of either morphophonology or syntax. Morphophonology is responsible for mapping the morphemes such as {je}, whose labels follow conventional spelling, onto phonological structures, and for French clitics this mapping would have to include various morphophonological mergers such as the merged pronunciation of {je} and {suis} as chuis – a pronunciation only found when {suis} realizes the verb ETRE, ‘be’, and not when it realizes SUIVRE, ‘follow’ (Miller and Sag 1997, 578). Similarly, the object pronoun le or la can be omitted provided it would immediately precede the pronoun lui (Bonami and Boyé 2007), as in (52): (51)Paul la lui apportera. Paul it to-him will-bring ‘Paul will bring it to him’ (52)Paul lui apportera. The easiest explanation for this pattern lies in the morphophonology, with {le}+{lui} or {la}+{lui} realized in the same way as just {lui}. The object pronoun must be present in the syntax, because it is required by the valency of apportera, and its realization must also be present in the morphology, because suppression is only possible ‘before lui’ – a condition on morphological structure. However these morphophonological details present no special challenges for a clitic-based analysis because precisely the same kinds of merger are found in English simple clitics, where you’re is homophonous either with your or with an unstressed realization of just you, /jə/. The next section turns to syntax, to discuss the details of clitic-climbing. The discussion will focus on just one part of the grammar to which we have so far paid no attention: the ‘host’ relation between the clitics and the host verb to which they are attached. The syntax hardly interacts at all with the morphosyntax so this discussion will ignore the latter. 10 Clitic climbing I have assumed so far that each clitic depends, in syntactic structure, directly on its host verb, but of course this need not be so, as can be seen from the following. (53) Je les ai trouvés. I them have found ‘I found them.’ (les depends on trouvés) Tu la laisses les lire? You her let them read ‘Do you let her read them?’ (les depends on lire) Tu les lui laisses lire? you them to.her let read ‘Do you let her read them?’ (les depends on lire) Jean lui a été fidèle. John to.her has been faithful ‘John has been faithful to her.’ (lui depends on fidèle) Jean en mange beaucoup. John of.it eats a.lot ‘John eats a lot of it’ (en depends on beaucoup, ‘a lot’) (54) (55) (56) (57) (58) (59) La fin en est désagréable. the end of.it is unpleasant 'The end of it is unpleasant’ (en depends on fin) Je l’ai entendu dire. I it have heard say ‘I’ve heard it said’ (l’ depends on dire) In each case, the underlined clitic pronoun is attached to a verb on which it depends only indirectly; for example, in (53) les is the object of trouvés, but is attached to ai. In every case, the clitic ‘climbs up’ the dependency structure. That means that it is attached to a verb which is a few links up the dependency chain – the chain of dependencies that ultimately links it to the sentence root. Indeed, in all of these five examples, the word to which the clitic attaches is the sentence root (the finite verb), but of course this need not be so: (60) J’ai visité la chambre où je les ai trouvés. I have visited the room where I them have found. ‘I visited the room where I found them.’ The question is precisely what the relation is between the dependency structure and the clitic’s choice of host verb, and why complications exist. The ‘why’ question is easy. Only verbs can host clitics, so if a clitic depends, say, on an adjective such as fidèle in (56), it has to find a verb to host it; and likewise en in (57). Moreover, past participles cannot host clitics at all (Miller and Sag 1997, 594), so the object of trouvés in (53) has to find a different verb as host. Though these restrictions themselves demand an explanation, once they exist they create a problem to which clitic climbing is the solution. There are four different patterns in which a pronoun P appears to climb: 1. P = any pronoun, climbing from past participle to auxiliary verb (e.g. les a trouvés, ‘has found them’) 2. P = object pronoun, climbing from infinitive to a higher verb (e.g. l’entends dire, ‘hear it said’) 3. P = Y/EN, climbing from predicative to verb (e.g. lui reste fidèle, ‘remains faithful to her’) 4. P = EN, climbing from subject or object to verb (e.g. la fin en est,’the end of it is’, en connaît la fin, ‘knows the end of it’) However it could be argued that patterns 2, 3 and 4 can all be left to the ordinary syntax. If nonpronominal equivalents of the pronouns are raised to act as complements of the verb, then the pronouns too are just ordinary raised, but non-climbing, complements. There is some evidence that this is in fact so for all three patterns. I have already mentioned the evidence in (21) to (26) regarding pattern 4, which shows that en has the same distribution as the relative pronoun dont as in pairs like the following: (61) (62) Marie en connaît la fin. Mary of.it knows the end ‘Mary knows the end of it.’ ... la seule histoire dont Marie connaît la fin ... ... the only story of.which Mary knows the end ... One interpretation of this evidence is that dont is always a dependent of the relative verb, and that therefore the same must be true of en. If this is so, it follows that en is always a syntactic dependent of the verb even if it is also a dependent of another dependent. For patterns 2 and 3, the relevant data contain non-pronominal equivalents of the clitics. For pattern 3, a relevant example would be (63): (63) Jean reste à Marie plus fidèle que tous les autres. John remains to Mary more faithful than all the others If this example is grammatical, then there must be some syntactic rule, unrelated to cliticization, which raises the complement of fidèle so that it acts as a dependent of the verb and can move before the adjective; and it is this raised dependency that justifies the use of the clitic in (64) (Miller and Sag 1997, 604). (64) Jean lui reste fidèle. John to.her remains faithful ‘John remains faithful to her’ If native speakers accept (63), pattern 3 can be left to the syntax. If not, it will need an extension of the clitic-climbing pattern offered below for Pattern 1. Pattern 2 involves infinitives, which (unlike past participles) do allow hostforms. The typical pattern with infinitives used as complement of a higher verb is shown in (65). (65) Ils peuvent nous le signaler dès son arrivée. they can to.us it notify as.from his arrival ‘They can tell us about it as soon as he arrives.’ Notice that the clitics that depend on the infinitive signaler alone are attached to this verb, whereas ils, which is raised to act as subject of peuvent in addition to its role as subject of signaler, is attached to the higher verb. In modern French (unlike earlier periods), the lower clitics cannot attach to the higher verb. However, there are some apparent exceptions: a handful of verbs which take a bare infinitive as complement and allow the latter’s pronouns to attach to them (Hawkins and Towell 2001, 70): (66) (67) Je les lui ferai manger ? I them to.him will.make eat ‘I’ll make him eat them’ Tu les lui laisses lire? you them to.her let read ‘Will you let her read them ?’ (68) Je le leur ai entendu dire I it to.them have heard say ‘I’ve heard them say it.’ In each of these examples the direct-object pronoun (les or le) is the object of the infiniive but shares its hostform with the higher verb, or even with the auxiliary on which the latter depends. Although this looks like clitic climbing, it is noteworthy that the ‘top’ clitic – the one dependent on the higher verb – has the form of an indirect object (e.g. lui, ‘to him/her’) rather than the expected direct object which does in fact appear if the lower object is left un-raised, as is sometimes possible in examples like these: (69) Tu la laisses les lire? you her let them read ‘Will you let read them ?’ As can be seen by comparing (69) with its synonym (67), the verb LAISSER, ‘let’, allows the object of its infinitive to attach either to the infinitive or to LAISSER, but in the latter case la changes to lui. This alternation is not peculiar to clitics, but is also found with full phrasal arguments as in (70) and (71): (70) (71) Tu laisses Marie lire Zola? you let Mary read Zola ‘Will you let Mary read Zola?’ Tu laisses lire Zola à Marie? you let read Zola to Mary ‘Will you let Mary read Zola?’ Seen as a syntactic phenomenon, the alternation has an easy explanation: the ‘Stratal Uniqueness Law’ of Relational Grammar (Perlmutter and Postal 1983). In particular, no verb may have more than one direct object. This principle also explains why English idiomatic constructions that add a direct object, such as the WAY construction in He groped his way to the door, cannot combine with a verb that already has an object (as in He ate his way to an early grave, but not *He ate burgers his way to an early grave). Given this principle, it is easy to see that a lower direct object in the French examples might be raised to act as a higher indirect object when the higher verb already has an object; but this explanation only works if the ‘raised’ argument really is raised, so that it and the higher direct object depend on the same verb. But if that is so, the direct-object clitics in (66) to (68) must have been attached to the first verb by syntactic raising rather than by clitic climbing. Returning to our list of four apparent cases of clitic climbing, I have argued that three of them may involve syntactic raising rather than clitic climbing, but we are still left with one inescapable example of clitic climbing: from a past participle to an auxiliary, as in (72). (72) Jean le lui a envoyé. John it to.him has sent ‘John has sent it to him.’ Here there is the usual strong evidence for the raising of the participle’s subject, but none for syntactic raising of its other dependents. We must therefore treat it as a genuine example of clitic climbing. Before moving towards an analysis of this construction, it may be helpful to review what the grammar built so far provides. Each clitic pronoun has two obligatory links: a ‘host’ link to the verb on which it depends, and a ‘hostform’ (‘hf’) link to a hostform which (by default) is anchored on the realization of this verb. It also provides some verbs with an optional ‘hf’ link, as required by any dependent pronouns that happens to need a host. This little grammar is shown in Figure 18, which also shows that past participles never have a hostform. verb dependent host 1 clitic past participle hf hf hostform hf 0 Figure 18: Clitics and their host verbs According to this grammar, a clitic’s host is also the verb on which it depends. But when we apply this analysis to ‘climbing’ examples such as le lui a envoyé, this means that the clitics’ host is the lower verb, the past participle – which is clearly the wrong analysis. To rectify this problem we need a special arrangement for climbing which adds an extra ‘host’ relation to the auxiliary and guarantees that this relation takes priority over the lower one. Provided the higher link ‘isa’ the lower one, default inheritance will provide the necessary guarantee, so all we need is the little extra grammar in Figure 19. This says that if a clitic’s host is a past participle which depends on an auxiliary verb, then that auxiliary verb takes over as the clitic’s host. And of course if several clitics all depend on the same past participle, they all take the same auxiliary verb as host. auxiliary verb past participle dependent clitic host Figure 19: Climbing to an auxiliary These two networks complete our grammar for French clitics, which consists of a number of individual sub-networks which, taken together, provide a coherent analysis of all the relevant cases. 11 Conclusions I should like to draw five general conclusions about language, and two specific conclusions about French clitics. My first general conclusion is that even a linguistic phenomenon as complex as French clitics can be modelled without assuming any formal apparatus other than what is probably needed for everyday thinking outside language. In short, the chapter vindicates the cognitive assumptions of (2): that a linguistic model is ultimately a model of the mental structures of a typical speaker, and that these mental structures are ‘domain-general’ – not specific to language. The analysis therefore supports the true minimalism of cognitive linguistics which reduces the special apparatus of language knowledge to zero. Secondly, this formal apparatus allows insightful analyses which accommodate both broad generalizations and fine details. This flexibility is mainly due to the logic of default inheritance and the ‘isa’ hierarchies which unify all categories, whether general or specific. When applied to French pronouns, the same apparatus accommodates general categories such as ‘clitic’ and ‘verb’, as well as specific categories such as [ETRE, 1sg] and {je}. But of course one important consequence of this analysis is that there is no division between ‘grammar’ and ‘lexicon’, so there can be no question about whether the clitics are handled ‘in the lexicon’. My third general conclusion is that language is a network, and nothing but a network (Lamb 1998). It is not a collection of box-like modules, nor is it a network of complex units such as constructions, signs, attribute-value matrices or lexical entries. Nor does it contain ‘rules’, ‘principles’ or ‘parameters’. All it consists of is a vast collection of links, with concepts at the points where links meet – in other words, each concept (whether linguistic or not) is simply an atomic meeting-point, whose content is defined entirely by its links to other such concepts. Every figure in this chapter illustrates this general claim through a network fragment which ultimately forms part of a single giant super-network; in such a network, the labels are redundant because they simply duplicate the information carried by the links. On the other hand, although language is a network, it is not a neural network but a symbolic one – part of the mind, not part of the brain – where each node corresponds to a concept. It is because the mind is symbolic and mental that it can accommodate structures that are as crystal-clear and as complex as those for French clitics. Fourthly, this mental network distinguishes different kinds of relations. A few kinds are probably hard-wired and universal; most obviously, the ‘isa’ relation underlies the very basic logic of default inheritance, so it must be hard-wired. But alongside these built-in relations we also find concept-like relations that are constructed as needed, just like ordinary concepts; so we have an open-ended isa hierarchy of ‘relational concepts’. This idea is important for linguistic analysis because the option of creating extra relations adds a new dimension of flexibility. For example, we can create ad hoc relations such as ‘host’ and ‘hostform’ without worrying about justifying them as part of a putative ‘universal grammar’. My last general conclusion is that morphology is an autonomous level of analysis, separate from both syntax and phonology though closely tied to both of these via ‘realization’ links – a very traditional view, but because it is so often challenged, one that needs the support of cognitive arguments. But the notion of ‘autonomous level’ needs to be reframed in a network model, because it is traditionally presented in terms of separate modules. In a network, levels are defined by the ‘realization’ and ‘meaning’ relations in combination with a classification of linguistic entities as words, morphemes and so on. As far as French clitics are concerned, my first conclusion is that they are, indeed, clitics, rather than inflectional affixes. Once again, the view is a familiar one, but its credentials are strengthened by cognitive arguments. The cognitive view also favours the proposed definition of clitics as syntactic words which are realized by morphemes, as against the vaguer tradition in which clitics are somehow intermediate between words and affixes. In a network with levels defined by the realization relation there is no place for such a unit, but there is plenty of room for exceptionality – in this case, words which exceptionally map onto an affix. My second conclusion about French clitics builds on this definition of clitics. I argue, controversially, that enclitics are simple clitics because their position follows the ordinary rules of syntax (with just one exception which reappears among the proclitics). In this sense, the hostforms (aka clitic clusters) of enclitics are the default, to which proclitics add the extra apparatus of an ordering template. On the other hand, affirmative imperatives are certainly not default verbs, so they are non-default verbs whose realization in morphology appears inside a default hostform.
