语法化最容易发生在句法结合比较薄弱的环节,不同句法关系的组合,表现出不同的语法化倾向性。宾语的缺位,使前面动词所受句法约束力减弱,语法地位降低,在一定的条件下容易状语化或副词化;处在非典型位置的语言成分因不稳定而易于发生语法化。各种句法关系处于结构化强度不同的层级上,其语法化的趋势随组合层级的降低而增强。 Grammaticalization most likely to occur in the syntactic combination of weak links, the combination of different syntactic relationships, showing a different tendency of grammaticalization. The vacancy of the object makes the front verb weaken the syntactic binding force, the grammatical status is reduced, and it is easy to governed or adverbized under certain conditions. The language component in the atypical position is prone to grammaticalization due to the instability. The various syntactic relations are at different levels of structural intensity, and the tendency of their grammaticalization is enhanced with the decrease of the level of combination.
