The category of dummy verbs includes both typical members and atypical members, the latter of which have not attracted enough attention of current scholars. A1 though ＂Vchu＂ （出） , such as zuochu （做出/作出）, geichu （给出）, tichu （提出） and fa- chu （发出）, are atypical members, they can distribute in the same positions where typical dummy verbs appear and have the same properties as typical ones. This paper shows that ＂V chu＂ are in the process of lexicalization. Further, the critical context for lexicalization of ＂V chu＂ lies in the fact that they take disyllable verbs as their objects, and the two ways of un- derstanding provide the condition for the transition from ＂V chu＂ to dummy verbs. Based on the above analysis, this paper points out that the typical distribution frame of dummy verbs, that is, ＂preposition ＋ patient ＋__＋ disyllabic transitive verb＂, is the final context for lexicalization of ＂V chu＂.
