语法化是关于语言演变的理论之一。本文从语法化的角度考察了汉英典型差比标记在历时演变中的特征,研究发现:汉英差比标记伴随各自句法结构的演变均发生了语法化,但汉语标记的语法化属于语言内部的演化,其起点是实词,由句法成分的重新分析而来,而英语标记的语法化动因较为复杂,其起点是虚词,表现为屈折法和迂说法的共时并存。 Grammaticalization is one of the theories about language evolution. This paper examines the characteristics of Chinese and English typical difference markers in diachronic evolution from the point of grammaticalization. It is found that the grammaticalization of Chinese and English difference markers with their respective syntactic structures takes place. However, the grammaticalization of Chinese markers belongs to internal language The starting point is the real word, which is reanalyzed from the syntactic components. However, the grammatical motivation of the English marker is rather complicated. The starting point is the function words, manifested as the synchronic coexistence of inflection and bypass.
