Postverbal secondary predicates (PSP) in Taiwan Southern Min (TSM) are introduced by -kah^4, -liau^2, or -tioh^8, each of which carries a different denotation. This paper argues that the PSPs introduced by each of these three markers can be further divided into three types-resultative, descriptive, and extent. The arguments are based on the scope of modification, the formation of passivization, and word order. Moreover, there exist co-occurrence restrictions between the main verb and the PSPs; achievement and accomplishment compound verbs are incompatible with PSPs. Even though PSPs with different markers behave similarly, they still differ in at least one aspect. PSPs introduced by -kah^4 may be deleted, while those introduced by -liau^2 or -tioh^8 are not optional.
