Most Korean Grammars have the category of compliment and it is considered as the remnant obligatory constituent. But this like expression cannot be an academic definition. Furthermore there is no grammatical marker of compliment in Korean. So I think we should not establish the category and in this paper I proposed as follows. 1. So called “‘-이/가’ compliment” should be considered as a subject of predicate clause. 2. The other so called “compliments” should be considered as adverbial constituents. 3. Then we can eliminate the empty compliment category.
