Semantics A. Three subfields of semantics: 1) lexical semantics 2) sentential semantics 3) pragmatics B. Phrasal & Sentential Semantics 1. What you should know about sentence meaning a) truth conditions 1) tautologies (analytic sentences): always true 2) contradictions: always false 3) paradoxes b) relation of sentences 1) entailment: If A is true, B is true. 2) paraphrase: with the same truth condition 3) contradictory: If A is true, B is false. 4) ambiguity C. Compositional semantics Compositional semantics cannot solve 1. anomaly a) nonsense b) no sense 2. metaphor 3. idiom D. Lexical Semantics 1. sense vs. reference 2. lexical relations a) synonyms b) antonyms 1) complementary antonyms 2) gradable antonyms 3) relational antonyms c) homonyms d) polysemy e) hyponyms f) metonym 3. semantic features/properties a) nouns: [+female/-female], [+human/-human], [+count/-count]…. b) verbs: [+cause/-cause], [+state/-state]… 1) argument structure: C-selection & S-selection 2) thematic roles: the relations of NPs depending on the meaning of the verb AGENT: the one who performs an action THEME: the one or thing that undergoes an action LOCATION: the place where an action takes place SOURCE: the place from which an action originates GOAL: the place to which an action is directed INSTRUMENT: the means by which an action is performed EXPERIENCER: one who perceives something CAUSE: a natural force that causes a change POSSESSOR: one who has something ** Thematic roles are determined in lexicon. ** Thematic roles are the same in sentences that are paraphrases. E. Pragmatics Pragmatics is concerned with the interpretation of linguistic meaning in context. 1. linguistic context – discourse a) pronoun b) the and a 2. situational context a) deixis 1) person 2) time 3) place b) Maxims of Conversation Quantity: say neither more nor less than the discourse requires Relevance: be relevant Manner: be brief and orderly; avoid ambiguity and obscurity Quality: do not lie; do not make unsupported claims ** Any violation of the maxims will lead to conversational implicatures. c) speech acts: use language to do things 1) performative verbs & performative sentences
