汉语的介词大部分都是从动词发展演变而来。在动词语法化为介词的过程中,往往与该动词的句法位置有关,同时动词的词义不断虚化。宋元时期,出现在“奔+O+来/去”的格式中的奔“意义开始发生细微变化,着重表示位移方向意义。明代,连动式”奔+O+V“中,”奔“处于语法化过程中,有的可以看作介词,有的已经是纯粹的介词。清代”奔“的介词用法已经完全成熟。 Much of Chinese prepositions have evolved from the development of verbs. In the process of the grammaticalization of a verb into a preposition, it is often related to the syntactic position of the verb, meanwhile the meaning of the verb is constantly vanishing. In Song and Yuan dynasties, the meaning of ”Ben“ in the format of ”Ben + O + come / go“ began to change subtly, emphasizing the meaning of displacement direction. In the Ming Dynasty, even in the ”Ben + O + V“ , ”Ben“ is in the process of grammaticalization, and some can be regarded as prepositions, some of which are purely prepositions. The preposition usage of Qing Dynasty ”Ben" has been completely mature.
