Abstract: ××Hua is a lexicalized construction in Chinese.Based on the description of the grammatical features of this construction,the present study explores the cognitive mechanism of integration between××andHua from the perspective of cognitive grammar.It has been found that there is a certain extent of conceptual overlap between××andHua,which constitutes the prerequisite for the reasonable semantics of the construction.The cognitive mechanism of integration varies with××being an adjective,a noun or a verb,so that the construction is polysemous.From an internal perspective of the construction,the cognitive nature of the varieties of the construction is always related to the sequential scanning.Under this construal way,the changing process of the trajecor of××becomes prominent.From an external perspective of the construction,××Hua,as a whole,functions as different word classes.
