Meaning and Decomposition Conceptual semantics
conceptual semantics distinguishes single, universal meaning word. instead of having lexical semantic meaning in addition conceptual representation of actual referent, here 2 combined jackendoff calls “lexical concepts” (murphy 2010:59). conceptual semantics considered not linguistic theory, theory on human cognition. many semantic theories, jackendoff claims decompositional method necessary explore conceptualization. 1 of ways physical scientist tries understand matter breaking down progressively smaller parts, scientific study of conceptualization proceeds breaking down, or decomposing, meanings smaller parts. however, decomposition cannot go on forever, @ point, meanings can no longer broken down.
this level of conceptual structure, level of mental representations encode human understanding of world, containing primitive conceptual elements out of meanings built, plus rules of combination. conceptual semantics not work mental dictionary, in classical sense. there no definitions attached concepts , reference, idea of concept or reference itself. generative syntax posits finite set of syntactic categories , rules combining them, so, too, conceptual semantics posit ‘a finite set of mental primitives , finite set of principles of mental combination’ governing interaction (jackendoff 1990: 9). jackendoff refers set of primitives , rules governing them ‘grammar of sentential concepts’ ( jackendoff 1990: 9).
his starting point close analysis of meanings of lexemes dedicated bringing out parallelisms , contrasts reveal nature of conceptual structures underlying them. jackendoff considers lexicon made of 3 parts: phonological, syntactic, , conceptual. these 3 aspects of concept give “full picture of word” (murphy 2010:60). method shows, says, psychological organization on meaning rests ‘lies short distance below surface of everyday lexical items – , progress can made in exploring it’ (1991: 44). jackendoff claims decompositional method necessary explore conceptual structure, in concepts underlying word meaning broken down smallest elements: conceptual primitives envisaged semantic equivalents of phonological features. conceptual semantics posits ‘a finite set of mental primitives , finite set of principles of mental combination’ governing interaction. conceptual structure of lexical item element 0 or more open argument slots, filled syntactic complements of lexical item.
