同构项变化的方式及其在语法化中的角色

Host-Class Changes in Grammaticalization: Modes and Roles

同构项有两种常见的变化方式,即在相同语法范畴内的同质性扩展和跨越不同语法范畴的异质性替换。同构项不能单独诱发导致语法化的语用推理,只是语法化项演变所依赖的条件之一。因此,同构项变化的准确定位是语法化项演变的附带现象。

The host-class members of a grammaticalizing item typically change in two modes, i. e. , the expansion within the same grammatical category and the shift across different grammatical categories. In neither mode can the host-class members trigger the pragmatic inference that lead to the grammaticalization on their own. The properties of host-class members are among the enabling factors of the decategorialization of grammaticalizing items, and the latter in turn creates the condition for the former. In this sense, host-class change is an epiphenomenon of the decategorialization of grammaticalizing items.
