담화표지 ‘다’에 대하여

The Discourse Functions and the Grammaticalization of ‘Da'(all)

The purposes of this paper are to elucidate the syntactic and semantic properties of discourse marker ‘da’(all). Generally ‘da’ is used as a adverb or noun, but it can be used as a discourse marker, too. In this paper I showed several evidences which support ‘da’ to be a discourse marker, and explored the meanings and syntactic phenomena of ‘da’. ‘Da’ appears with high frequency in oral discourse and has no lexical meaning, so it is optional in sentence. ‘Da’ can appear sentence medially and finally as well. I argued that the main function of ‘da’ is to represent the speaker’s unexpectedness. Also in this paper I discussed the process that ‘da’ becomes a discourse marker. I demonstrated that discourse marker ‘da’ had been derived from adverb/noun through the pragmatic strengthening in grammaticalization.
