発話行為理論から見た文末の接続表現の用法 : カラ・ケド・シを中心に発話行為理論から見た文末の接続表現の用法 : カラ・ケド・シを中心にAN00237324 A Speech Act Theory Approach to Japanese Conjunctive Particle Used in the End of Sentences: Focusing on Kara, Kedo and Shi
Unfinished sentences which end with conjunctive particle such as kara, kedo and shi are often used in the spoken Japanese. This paper aims to clarify and systematize the usage of kara, kedo, shi as an end-of-sentence expression from the viewpoint of speech act theory. Firstly, the omitted main clauses will be recovered depending on their context, then summarized the illocutionary acts of main clause and subordinate clause. It is found that usage patterns of kara, kedo, shi as an end-of-sentence expression are different from those of a connective expression. Kara is generally believed to be a connective expression which indicates reason or cause. When used at the end of a sentence as the pattern of 'assertive＋Ø', it may not express a reason but the speaker's strong intention. Kedo used in unfinished sentences serves not only the same function as a connective expression, but also as request for improvement to hearer's actions or thoughts. In addition, shi can indicate cause from a speaker's viewpoint in order to convince a hearer, functionally similar when used as conjunctive particle. Also, it can express the speaker's negative emotion as a characteristic usage.
