Based on the theory of grammaticalization, this paper will discuss whether ‘V+Vd+NP+lai’ has the identity as ‘V+Vd+lai’. ‘V+Vd+NP+lai’ is a structure created through different grammaticalization processes from ‘V+Vd+lai’ as follows: V+Vd+NP+lai : V+NP+lai > Vd+NP+lai > V+Vd+NP+lai V+Vd+lai : Vd+lai > V+Vd+lai According to the above diagram, the syntactic structure of ‘V+Vd+NP+lai’ is a combination of ‘lai’, which represents completion (realization), behind the V-D Structure in which a simple directional complement is combined. On the other hand ‘V+Vd+lai’ corresponds to V-D Structure having a compound directional complement. Therefore there is no identity between these two structures. This non-identity not only makes a difference in meaning between the two structures, but also creates different constraints in terms of syntactic. In particular, the difference in object components clearly reflects the absence of identity of the two structures. Specifically, in ‘V+Vd+NP+lai’, only ‘V+Vd’ is the predicate part, so the object ‘NP’ is mainly in charge of noun components. On the other hand, ‘V+Vd+lai’ is a kind of V-D Structure in which the entire sentence serves as a predicate, and if necessary, it can have an object after it. At this time, not only nouns (non-locative components) but also verbs and even clauses can appear as the object.
