Following the claims made in Kim(2003), this article investigates how the contrastive -nun and the matching -nun phrases, which have been dubbed under one name as Contrastive Topic, are different. It first examines what properties are found among focus phrases in general. Then the two -nun phrases are tested against the general properties of focus phrases. It is found that the contrastive -nun phrases behave the way other focus phrases do and the matching -nun phrases do not. Therefore it is concluded that the contrastive phrase is, unlike the matching phrase or the regular topic phrase, in fact a kind of focus phrase.
