Chung, Kyung-Sook. 2014. The Korean Sentence-Final Suffix –ney and the Assertive Speech Act. Korean Journal of Linguistics, 39-3, 617-640. This paper shows that the Korean sentence-final suffix –ney should not be treated as an epistemic modal like the English modal must, nor as an evidential or mirative. Instead, the paper argues that, like the declarative suffix –ta, –ney should be a sentence mood that basically expresses an assertive speech act, and that the difference between the two is that –ta is a sentence mood that requires that the described proposition be‘informative to the hearer', whereas -ney is a mood that requires that the proposition be‘informative to the speaker'. Thus the proposed analysis suggests that the assertive speech act can be at least two subtypes, the assertion for informativeness and the assertion for the speaker's own knowledge.
