#3402. presupposition trigger のタイプ[presupposition][pragmatics]


 語用論の主要なトピックである presupposition (前提)とは,簡単にいえば,ある文を発したときに当然のように真として受け入れられる推論や命題のことである.例えば,「私の兄は独身です」では私に兄がいることが前提とされるし,「雨が降る前に洗濯物を取り込んだ」では雨が降ったことが前提とされる.これらの文において件の前提を生み出す言語項を presupposition trigger と呼ぶ.上の例では,「私の兄」という名詞句や「雨が降る前に」という統語構造が presupposition trigger となっている.
