Outline of Final Research Achievements

This study analyzes the semantic structure of the following (subsidiary) verbs focusing on their propositional meaning, non-propositional meaning, and their interrelationship: `V-hazime(ru)', `V-kake(ru)', `V-das(u)', and `V-tek(uru)'. It also discusses the relation between their semantics and syntactic structures. The propositional and non-propositional meanings of `hutuu-ni', the meaning and usage of which seems to have changed in recent years, is also discussed, and it is suggested that it shows the similar changes as the grammaticalization of verbs. As for English, we analyze `have got', which means possession and light verb constructions featuring `give' as the main verb, and find that their speech act meaning, non-propositional meaning, plays an important role.

Academic Significance and Societal Importance of the Research Achievements

語彙意味論では、動詞の真理条件的意味を記述するLCS (語彙概念構造)を用いて同値類を括り出し、動詞の意味と統語構造との関係が議論されてきた。また、Pustejovsky (1995) 以降は、いわゆる百科事典的知識とされる非真理条件的意味も一部語の特質構造に属する意味要素として取り入れ、レキシコンと語用論とのインターフェイスを理論的に扱うことが可能になったが、これらの意味のレキシコン理論内での扱いについて未だ共通見解はない。本研究はレキシコンにおける真理条件的意味と非真理条件的意味の位置付けとその関係性を論じたという意味で、その課題解決を目指すための解答例を示したものと位置付けられる。
