1, the relationship between lexicalization and grammaticalization. This is a question that many scholars care about, and it is also one of the questions that I am often asked. Lexicalization and grammaticalization have many similarities and differences, and different scholars have given different answers to the relationship between them. The article "The connection and difference between lexicalization and grammaticalization: Taking some lexicalization in Chinese history as an example" not only summarizes various views of predecessors on the relationship between lexicalization and grammaticalization.
2. The relationship between lexicalization and syntactic evolution. I think that syntactic evolution is an important reason for lexicalization. The article Syntactic Evolution and Lexicalization of Chinese reveals the inductive effect of syntactic evolution on lexicalization with some concrete facts.
3. Lexicalization and the formation of discourse markers. Discourse markers are one of the hot topics in linguistics in recent years. Academic circles have different views on the formation of discourse markers. Some people think that the formation of discourse markers is the result of grammaticalization, others think that the formation of discourse markers is the result of pragmatics, and the formation of discourse markers can be the result of lexicalization. Accurately speaking, the formation of some discourse markers belongs to the first stage of lexicalization: idioms.
4. The relationship between lexicalization and syntactic structure. Lexicalization, especially lexicalization of cross-level structures, often occurs in specific syntactic structures. Therefore, to describe the process and mechanism of lexicalization, we must pay attention to the construction environment of lexicalization. The article Syntactic Structure and Lexicalization takes Chinese history and dialects as examples to discuss the role of syntactic structure in lexicalization.
