LIN 1180 – Semantics Lecture7 Albert Gatt Continuation from last week Ambiguity and vagueness Ambiguity vs. Vagueness (I) In context, a word can seem to have several distinct senses. Some may appear more related than others. In our example: run1 = physical act of running run2 = place where fowl are kept So run is 2-ways ambiguous (2 senses) But run1 exhibits vagueness between a general sense of running, and the more specialised sense used in cricket. Ambiguity vs. vagueness (II) Similarly: daħla1 = entrance or inlet daħla2 = introduction to a text 2-ways ambiguous daħla1 is vague between the sense of “entrance” and that of “inlet” Ambiguity vs. vagueness (IV) Ambiguity: In this case, the context will select one of the meanings/senses We often don’t even notice ambiguity, because context clarifies the intended meaning. Vagueness: Context adds information to the sense. Therefore the sense of the word itself doesn’t contain all the information. It is underspecified. Tests for ambiguity and vagueness There are some tests to decide whether meaning distinctions involve ambiguity or vagueness. The do-so test of meaning identity The synonymy or sense-relations test The do-so test: preliminary example I ate a sandwich and Mary did so too did too The do-so construction is interpreted as identical to the preceding verb phrase Similar constructions in Maltese: Kilt biċċa ħobż u anka Marija Kilt biċċa ħobż u Marija għamlet hekk ukoll. The do-so test and meaning identity Main principle: if a particular sense is selected for a word in a verb phrase, it will also be the same sense in the do-so phrase Therefore, very useful to test if two meanings are two distinct senses. Do-so examples Lili għoġbitni d-daħla u lil Jimmy wkoll (I liked the entrance/introduction and so did Jimmy) Suppose daħla here = “introduction” Is it possible that I liked the introduction and Jimmy liked the entrance? If not, then these are two distinct senses or daħla I made a run and so did Priscilla If “I made a run” = “I ran”, then Priscilla cannot have made a run for her chickens... So, again, these are two distinct senses of run. The sense relations test Basic principle: Words exhibit synonymy or similarity of meaning to other words. Therefore, if a word is ambiguous, we can substitute it for a similar word in the same context, and see if the meaning stays roughly the same. Sense relations examples Recall: run1 = physical act of running (similar word: jog) run2 = a closed space for animals (similar word: enclosure) Pete went for √ a run . √ a jog *an enclosure We can’t substitute one set of words for another and still keep the same meaning. Lexical relations: basic concepts We have established that: words in the lexicon can have multiple senses (ambiguity) they can also be vague, so that the actual meaning is underspecified and becomes clearer in context In addition: Words are not merely listed they are often related to one another LIN 1180 -- Semantics Part 1 Homonymy, polysemy, synonymy How is the lexicon structured? Lexical items belong to semantic fields words that belong to the same “topic” ,“subject” or “usage” lexical relations are often strongest within a semantic field different senses of a word often fall into different fields Examples: computing: gigabyte, CPU, memory, disk, monitor administration/diplomacy/politics: green, monitor, parliament, election Notice that monitor here has two senses, each falling in a different field. LIN 1180 -- Semantics Homonymy -- I Homonyms are unrelated senses of a the same phonological or orthographic word. sometimes we use homographs for unrelated senses of a written word could be considered different words lexicographers often treat derivationally related forms as homonyms Examples: bank (river) / bank (financial) ring / wring house (N) / house (V) right / write LIN 1180 -- Semantics Two subtypes of homonymy homphony ring / wring same phonology different orthography homography articulate (ADJ) / articulate (V) Maltese: domna (V) (stay-late.3PL) / domna (N) (religious icon) different phonology same orthography LIN 1180 -- Semantics Polysemy One phonological word, multiple senses (ambiguity) senses are related, though distinguishable cf. daħla (entrance) vs. daħla (inlet) in traditional dictionaries, multiple senses are listed under the same head word. LIN 1180 -- Semantics Homonymy vs. polysemy Relatedness: homonymy: senses are unrelated; polysemy: senses are related either historically or based on speaker intuition NB: Not always a clear-cut distinction. Speakers’ intuitions vary considerably. Do you consider sole (“bottom of foot”) and sole (“flat, riverbed fish”) related? LIN 1180 -- Semantics Synonymy Different phonological words with highly related meanings: sofa / couch boy / lad żgħir (small) / ċkejken (little) moxt (comb) / petne (comb) Very very difficult to find examples of perfect synonyms. LIN 1180 -- Semantics Imperfect synonymy Synonyms often exhibit slight differences, espcially in connotations petne (“comb”) has Romance origins; probably used by most speakers today moxt (“comb”) has Semitic origins (cf. xuxa “hair”) Usage differs depending on dialect, context… LIN 1180 -- Semantics The importance of register With near-synonyms, there are often register-governed conditions of use. Register = a style of language specific to a situation (e.g. formal, colloquial etc) E.g. naive vs gullible vs ingenuous gullible / naive seem critical, or even offensive ingenuous more likely in a formal context LIN 1180 -- Semantics Synonymy vs. Similarity Native speakers often have strong intuitions about words which are “related”, though not necessarily identical, in meaning. E.g. boat/ship; car/truck; man/woman But also near-synonyms such as: snake/serpent Similarity is broader than synonymy, since even words with “opposite” or “antonymous” meanings can be judged as similar; e.g. large/small LIN 1180 -- Semantics When are two words similar? Contextual view of meaning (Wittgenstein, 1953…): the meaning of linguistic expressions can be characterised by looking at how they are used two words are similar to the extent that they’re used in similar ways LIN 1180 -- Semantics Example: master/pupil These words have very different meanings, but share a core set of uses. Both refer to human roles which tend to be practised in the same real world contexts (school etc). Is this reflected in the way we use the words? master of X school, pupil of X school past master, past pupil … Rather than in contextual terms, we could view similarity as simply arising from links in a network of concepts. LIN 1180 -- Semantics Part 2 Opposites and antonymy Semantic opposition Traditionally, antonyms are words which are opposite in meaning. dead – alive We can find other kinds of opposition: hot – cold explode – implode writer – reader, employer – employee black – white, red – orange (?) LIN 1180 -- Semantics Simple vs Gradable antonyms Simple antonyms: dead – alive, hit – miss truth of one implies falsity of the other ? X is dead but he’s alive. Gradable antonyms: hot – cold, big – small both may be “false”: neither tall nor short typically, many terms to express gradations: hot >> warm >> tepid >> cool >> cold often modifiable with intensifiers: very hot, somewhat cold exhibit global dependencies: If we say X is big, we mean “big for an object of type X” big elephant is much bigger than a big mouse LIN 1180 -- Semantics Reverses and converses Reverses: explode – implode a kind of opposition where one terms “reverses” the other. often found with terms related to movement (go/come, etc) Converses: employer – employee, own – belong to describe a relation between two entities from different viewpoints “complement eachother” if X is Y’s employer, then Y is X’s employee if X owns Y, then Y belongs to X LIN 1180 -- Semantics Taxonomies Colour red orange yellow green blue •Taxonomies are classification systems, often in the form of a tree. •Sisters are elements at the same level. LIN 1180 -- Semantics Taxonomic sisters Usually taken to be complementary or “opposed” or “incompatible” or “mutually exclusive” NB: Taxonomies are often our way of imposing a discrete categorisation on a continuum (e.g. colour). LIN 1180 -- Semantics Opposites and similarity To many native speakers, the most highly related word to an adjective is its antonym or opposite. also typical of taxonomic sisters does this mean that opposites are synonymous? No! It just means that “similarity” under the contextual view is much broader than synonymy. LIN 1180 -- Semantics Part 3 Hyponymy and other relations Definition of hyponymy Hyponymy is a relation of inclusion. ANIMAL Arrows can be interpreted as “IS-A” relations. Unlike taxonomic sisterhood, which is horizontal, hyponymy is vertical. LIN 1180 -- Semantics BIRD CANARY MAMMAL SPARROW Elements of hyponymy If Y IS-A X then: X is the superordinate or hypernym of Y Y is a subordinate or hyponym of X e.g. HUMAN is the hypernym of MAN, TOOL is the hypernym of CHAINSAW Inclusion: if Y is a hyponym of X then Y contains the meaning of X (plus something extra) e.g. MAN includes all the features of HUMAN, plus the specification of ADULT and MALE. Transitivity: if X IS-A Y and Y IS-A Z, then X IS-A Z LIN 1180 -- Semantics Transitivity -- illustration A CANARY IS-A BIRD ANIMAL A BIRD IS-A ANIMAL Therefore, a CANARY IS-A ANIMAL BIRD CANARY LIN 1180 -- Semantics MAMMAL SPARROW Special cases of taxonomic relations Sometimes, language exhibits special cases of relations that are: well-established and lexicalised seem to depend on an underlying taxonomy or hierarchy ADULT-YOUNG dog – puppy, duck – duckling, etc MALE-FEMALE woman – man, dog – bitch, drake – duck, etc NB: These pairs are often asymmetric. The unmarked case in the MALE- FEMALE is the MALE. We tend to use it for the name of the species. LIN 1180 -- Semantics Meronymy or part-whole A different kind of taxonomic relationship. Arrows are interpreted as “HAS-A” ANIMAL LEG HAS-A IS-A BIRD WING HAS-A LIN 1180 -- Semantics Meronymy vs. Hyponymy Meronymy tends to be less regular than hyponymy: NOSE is perceived as a necessary part of a FACE CELLAR may be part of HOUSE, but not necessarily Meronymy need not be transitive: If X HAS-A Y and Y HAS-A Z, it does not follow that Y HAS-A Z window HAS-A pane room HAS-A window ??room HAS-A pane Common-sense knowledge plays a very important role in acceptability of these relations. LIN 1180 -- Semantics Member-collection relations We often lexicalise names of collections of specific things: flotta (fleet) : a collection of ships merħla (flock): a collection of sheep Native speakers know there is a member-collection relation: flotta (fleet) – vapur (ship) armata (army) – suldat (soldier) merħla (flock) – nagħġa (sheep) Can be viewed as a special, lexicalised case of meronymy. LIN 1180 -- Semantics Are collections singular or plural? In many languages, there is the possibility of switching from: a view of a collection as a single entity vs. the “contents” of the collection as a group or set English: The band played well tonight. It drove the crowd nuts [SG] They drove the crowd nuts [PL] Maltese: L-armata rtirat (The army retreated.SG) ?L-armata rtiraw. (The army retreated.PL) Perhaps not as acceptable? Only with some nouns? LIN 1180 -- Semantics Portion-mass Mass nouns: nouns denoting things which have no units noun is also true of portions of the substance liquid, coal, hair Languages often have lexicalised concepts denoting portions of specific substances: qatra (drop) for liquids strand of hair LIN 1180 -- Semantics Summary This lecture gave an overview of some standard ways to classify relations between lexical items. homonymy vs. polysemy synonymy (and contextual similarity) taxonomic relations: part-whole and hyponymy LIN 1180 -- Semantics
