A USAGE-BASED ACCOUNT ON THE KOREAN SUFFIX -TA IN SPOKEN DISCOURSE.

This paper investigates the usage of the Korean plain speech level suffix -ta in spoken discourse and discusses the relationship among its interactional functions, the local contexts of its use, and its basic meaning. This paper employs a usage-based approach, whereby naturally occurring spoken discourse is analyzed in detail by examining how the functions of -ta are distributed and to what extent the suffix is adapted to its context through the development of local patterns. The suffix -ta functions differently in terms of sentence types: on the one hand, it serves as a reactive token, an attention-getter, a self-repair, or a stance marker by indexing the speaker's cognitive process in spontaneous sentences. On the other hand, it can function as a way to claim speakership by indexing the on-going interactional process in non-spontaneous sentences. On the whole, compared with the intimate speech level suffix -e/a, the various functions of -ta are grounded in the representation of cognitive and interactional processing among conversation participants as the primitive form of their internalized knowledge. -Ta's frequent collocations with -keyss-, mac-, and ani- explain the highly adaptive feature of -ta to its local contexts. This paper reveals that the grammatical, lexical, and interactional contexts in using -ta contribute to the emergence of its interactional functions and its basic meaning. [ABSTRACT FROM AUTHOR]
