This paper analyzes as a transitive light verb and a phase head the Tsou suffix -a, the Mandarin preverbal particle gei_(TR), and Taiwan Southern Min preverbal particle ka_(TR). As a phase head, -a, gei_(TR), and ka_(TR) bears an edge feature and attracts the direct object within its c-commanding domain to its outer specifier, from where the shifted direct object can move further up in the sentence. This phase-based account explains not only the obligatory movement of a direct object but also the multiple occurrences of -a/gei_(TR)/ka_(TR) within a sentence.
