Morphology Part 2 Andrew Hippisley a.hippisley@surrey.ac.uk Plan 1. 2. 3. 4. 5. The structure of the lexicon WFRs and morphological operation types Aronoff’s indexed stems Productivity and WFRs Head and modifiers in word formation 1 The structure of the lexicon 1.1 Chomsky’s Aspects (1965) 1.1.1 Inflectional morphology as features S NP Det the VP N +pl boy V +pl run 1.1.2. Morphological rules inflectional features are related to phonological strings (basic alternants) this is done by Readjustment Rules (RRs): change abstract features into abstract forms the output of the RRs is the input to the Phonological Rules – they spell out the phonetic expression 1.1.3. What happens in the lexicon? lexical entry o free morphemes o semantics o sub-cat info. o syntactic category o phonological info. (basic alternants, idiosyncratic info. for spell-out) generalizations over lexical features, o e.g. +human implies +animate 1 1.2 Chomsky’s Remarks (1970) 1.2.1 Two kinds of nominalization: gerundive and derived a. The enemy destroyed the city with fire b. The enemy’s destroying the city with fire... c. The enemy’s destruction of the city with fire... d. Tom amused the children with his stories e. Tom’s amusing the children with his stories... f. *Tom’s amusement of the children with his stories... 1.2.2 Lexicalist Hypothesis ban on category changing T-Rules category and sub-category information that is the result of derivation needs to be specified before lexical insertion call for a linguistic component to account for derivation – the lexicon sarcastically a. Dick' s criticizing the book *sarcastic *sarcastically b. Dick' s criticism of the book sarcastic 1.2.3 Lexicon free morphemes derived words lexical redundancy rules: relating derivational pairs, capture generalizations idiosyncrasies 1.3 Halles Prolegomena (1973) 1.3.1 The lexicon the lexicon has an architecture all morpheme types included (back to item and arrangement?); derived words degrees of productivity: captured by the filter component. Potential words. WFRs 2 2 WFRs and morphological operation types 2.1 Word formation as lexeme formation morpheme-based: word’s meaning computed by adding the meanings of all embedded morphemes reliance on one-to-one correspondence of morpheme to form BUT: ‘zero morphs’, ‘empty morphs’, ‘superfluous morphs’, and ‘homonymous morphs lexeme-based: Derivation is viewed as the way the overall meaning and overall phonology of a Base lexeme is related to the overall meaning and overall phonology of a Derivative lexeme. Morphological description will thus fall out from viewing how lexemes relate to one another. 2.1.2 The structure of the lexeme. Example Russian stol ‘table’ syntax: noun semantics: STOL ' table' phonology (stem ): / stol / grammatical wordforms: stol[acc sg], stol[dat pl], stol[gen pl], etc. 2.1.3 Lexeme-formation: changes at the three levels of description. Example: Russian dobrot(a) ‘kindness’ derived from dobr(ij) ‘kind’. Base syntax: adjective semantics: DOBRIJ ' kind' phonology (stem): / dobr / Derivative syntax: noun semantics: DOBROTA ' quality of being kind' phonology (stem): / dobrot / 3 2.1.4 Accounting for transposition. Example: Russian adjective serebr´an(ij) ‘silver’ derived from the noun serebr(o) ‘silver’. Note: semantic level largely unaltered. Base syntax: noun semantics: SEREBRO ' silver' phonology (stem ): / serebr / Derivative syntax: adjective semantics: SEREBR ANIJ ' silver' phonology (stem): / serebr an / 2.1.5 Accounting for zero derivation. Example: Russian adjective zolot(oj) ‘gold’ derived from noun zolot(o). Base syntax: noun semantics: ZOLOTO ' gold' phonology (stem): /zolot / 2.2 Derivative syntax: adjective semantics: ZOLOTOJ ' relating to gold' phonology (stem): / zolot / Aronovian WFRs (Aronoff 1976; 1994) 2.2.1 Structural description and structural change WFR base x semantics: y phonology: z syntax: structural description syntax: cx semantics: cy phonology: cz structural change x semantics: y phonology: z syntax: 4 2.2.2 Syntactic conditions. (a) derivation in –ness: thankful -> thankfulness (b) Russian. Derivation in –tel´: uči(t´) ‘to teach’ -> učitel´ ‘teacher’ (c) Russian. Personal derivation in –n´ik: pomošč ‘help’ -> pomoščn´ik ‘helper’ (d) Russian. Personal derivation in –ec: slep(oj) ‘blind’ -> slepec ‘blind man’ 2.2.2.1 Unitary Base Hypothesis 'The syntacticosemantic specification of the base, though it may be more or less complex, is always unique. A WFR will never operate on either this or that.' (Aronoff 1976:48) 2.2.3 Semantic conditions a. John punched Bill. b. *John repunched Bill. c. John punched the holes in the paper. d. John repunched the holes in the paper Russian example: a Base abbat gloss abbot Derivative abbatsk(ij) gloss abbot (adj) b c d baron avtor advokat baron author barrister baronsk(ij) avtorsk(ij) advokatsk(ij) baron (adj) author (adj) barrister (adj) e f g h i š um apel´s´in bereg akul(a) slon noise orange coast shark elephant š umov(oj) apel´s´inov(ij) beregov(oj) akulov(ij) slonov(ij) noise (adj) orange (adj) coastal shark (adj) elephantine 5 2.2.4 Phonological conditions. Italian data (Scalise 1986: 47-48) 1. fortunato leale corretto gradevole 2. umano onesto educato abitato lucky loyal correct pleasant human honest well-mannered inhabited sfortunato sleale scorretto sgradevole *sumano / disumano *sonesto / disonesto *seducato / diseducato *sabitato / disabitato 3 Aronoff’s indexed stems 3.1 Multiple stems or multiple operations? (Zwicky 1996) unlucky disloyal incorrect unpleasant inhuman dishonest ill-mannered uninhabited Russian example: kot´onok ‘kitten’ (a) paradigm of wordforms nom acc gen dat inst loc Singular kot´onok-Ø kot´onk-a kot´onk-a kot´onk-u kot´onk-om kot´onk-e Plural kot´at-a kot´at-Ø kot´at-Ø kot´at-am kot´at-am´i kot´at-ax (b) lexemic representation: more than one stem (Hippisley 1998) syntax: noun semantics: KOT ONOK ' kitten' phonology (stem inventory): stem sg / kot onok/ ; stem pl / kot at / 3.2 A stem with multiple functions: the third stem in Latin verbal morphology (Aronoff 1994) (a) Three stems in Latin verbs Present Active Infinitive amā -re laudā -re Perfect Active amā v-i laudā v-i 6 Perfect Passive Participle amā t-us laudā t-us (b) The future active participle and the third stem verb am(ō ) 'love' cale(ō ) 'be hot' dole(ō ) 'suffer pain' iace(ō ) 'lie' perfect passive participle amā t-us * * future active participle * iact-ū r-us amā t-ū r-us calit-ū r-us dolit-ū r-us (c) The supine and the third stem i. abi- ı̄ dormit-um depart-1st.Sg.Perf.Act sleep-Sup.Acc.Sg 'I went away to sleep' ii. mirabile dict-ū wonderful say-Sup.Abl.Sg 'wonderful to relate' (d) Derivatives and the third stem Verb Base can(ō ) vinc(ō ) 2.

High availability, but low profitability. Semantic conditions? (Carstairs-McCarthy 1992: 37). (b) warmth, breadth, depth 4.3 regularity (a) greenth? (Bauer 1988: 60). 4.4 Blocking and semi-productivity (Aronoff 1976). monster monstrous monstrosity *cury curious curiosity glory glorious *gloriosity 5 Head and modifier in derivation 5.1 Endocentric compounds (Spencer 1991) (a) [ film society ] (b) [ [ film society ] committee ] (c) [ [ [ film society ] committee ] scandal ] Head: Modifier: labour laborious *laboriosity ‘the meaning of the construct is a sub-type of the head’ Zwicky (1993) ‘plays a contributory role, restricting the meaning of the head in one way or another.’ 5.2 Head is on the right; semantic, syntactic and phonological percolate from the head 5.3. Exocentric: lazybones, pickpocket, cut-throat. Note: left element is predicate-like; right element is argument-like. Appear to be lexicalised phrases. 8 5.4 Dvandva: elements related by conjunction: Austria-Hungary, red-green, motherchild 5.5 Heads in affixation? Williams (1981) Right-Hand Head Rule covers all complex words alike. In affixation, the head is the suffix. e.g. breadwinner, the head is –er. Argument against this is that heads should be able to be treated as full words for lexical insertion; they also should carry the bulk of the semantic features. Suffixes are semantically much more like modifiers. 5.6 NLP application of head-modifier relation (Hippisley et al. forthcoming) (a) Eliciting hyponyms of qì; 器 ‘tool’ Information extraction task: Elicit members of category Search schema used: [X [substring] ] Query example: [ X [qì]N ]N (b) Table 8.
