This chapter presents an examination of the Korean sentence-final suffix ci. The analysis developed here by Eun-Ju Noh builds on a body of work in relevance theory on discourse markers or particles – these are typically non-compositional elements of linguistic form that do not affect propositional content, but rather indicate something about the speaker’s attitude towards or evidence for that proposition. With regard to ci, Noh argues that existing treatments of it as an epistemic or attitudinal marker are unable to account for the full range of cases, and that it is better analysed as a metarepresentational marker indicating that the propositional form represents not a state of affairs in the world but rather the speaker’s own representation of that state of affairs.
