Abstract: The degree of sanctioning the Potential Verb-complement Constructions “V de C” (PVC) concerns the semantic type of verbs. Based on Langacker’s Verb Schema, this article classifies the verb into such four types as verbs of accomplishment, verbs of state, verbs of achievement, and verbs of activity, and sets three parameters, i.e. punctuality, homogeneity, and boundedness. The linguistic data show that the influence of verbs’ semantic type on the sanctioning the PVC from up to down is verbs of activity> verbs of achievement> verbs of state> verbs of accomplishment. The restrictive degree of the three parameters on the PVC from up to down is manifested as: punctuality> homogeneity> boundedness. According to the interaction of components in language construction, the motivation for verbs’ semantic type to sanction the PVC lies in temporal extension and temporal boundedness.
