Korean inflectional forms are combined with phrases, clauses, and sentences in Syntax, and with words in Morphology. Having two different areas of concatenation, the inflectional forms may result in mismatch between Syntax and Morphology. In this paper, I examined how the relation between Syntax and Morphology have been dealt with in the literature. The mismatch is noted as early as in Ju(1910), who incorporated the observation in his grammatical analysis. Heo(1983) also raised a question about this mismatch along with in-depth discussion about the problem, without a plausible solution. Recent Transformational Grammarians in Korea reconsider the problem assuming that the inflectional forms of Korean language are heads of the phrases. This approach shed light on the problem of the mismatch by supposing them as syntactic affixes in Morphology with the adoption of root-movement in Syntax. It is also shown that this problem can be resolved in the framework of Sadock(1991)'s Autolexical Syntax, in which Korean inflectional forms are treated as critics.
