“只是”词汇化的历程、动因及机制.

Based on the CCL corpus and the full-text retrieval system of Chinese books, the author investigates the lexicalization process, motivation and mechanism of " (zhishi)” from a diachronic perspective. The results show that the cross-layer structure" (zhishi)" first appeared in the Wei, Jin and Six Dynasties. In the Tang Dynasty, it was lexicalized into adverbs under the joint action of prosodic constraints, the expansion of subsequent components, the change of syntactic position and the increase of frequency of use. Reanalysis is an important mechanism for the lexicalization of “(zhishi)”. Similarly, in the Tang Dynasty, the adverb “ (zhishi)" was also grammaticalized into a conjunction under the mechanism of context absorption. “ (zhishi)" as a cross-layer structure, an adverb and a conjunction is all used in modern Chinese.
