In actual language corpus, there exists a phenomenon of semantic dislocation between “Du1 (度1)” and “Du2 (度2)”. The sense of “Du1 (度1)” is mainly a noun, but it also has a verb sense of “according to rules”. On the other hand, “Du2 (度2)” is mainly a verb, but it has a noun sense, which is a military term. Based on domain restriction analysis, this paper analyzes the syntactic position, semantic evolution and domain restriction changes of the dislocated semantics, and examines the semantic evolution process of the two. It is found that when the verbal noun “Du (度)” undergoes a part-of-speech change, it is often influenced by external factors of language, leading to a sudden mutation in domain restriction. However, when “Du (度)” is only subject to internal language mechanisms, its part-of-speech does not change, and it only extends new meanings within the domain field and transitional domain field. Therefore, the study of domain restriction has practical significance in the classification of Chinese verbs and nouns.
