This paper is an attempt to make a proposal for the constructions with kes morpheme in Korean which can accomodate a syntactic approach by Kang (2006) and an information structure approach by Kim and Sells (2007). While dealing with certain differences between what is called pseudo-clefts and what is called inverted pseudo-clefts in Korean by Jhang (1994), I propose that the difference in syntactic structure as well as that in information structure creates a difference in grammaticality. To be more specific, it is claimed that in a predicative use of a copular sentence, the subject and the predicate do not have to belong to the same syntactic category because information structure does not require it whereas in an equative use of a copular sentence they should belong to the same category because information structure asks for it. The occurrence of a PP permitted only in one construction can also be explained by the unified approach.
