在汉语语法史上,《文通》第一次提出了“助动字”的概念并建立了自己的助动字系统。这一概念的提出及理论阐述对后人的研究产生了积极的影响。自《文通》以后,很多学者开始思考汉语的助动词问题,他们继承了《文通》的助动字系统对之作了进一步的发展。 In the history of Chinese grammar, Wutong first proposed the concept of “auxiliary word” and established its own auxiliary word system. The introduction of this concept and theoretical exposition have had a positive impact on future generations' research. Since the introduction of Wutong, many scholars have started to think about the auxiliary verbs in Chinese. They inherited the auxiliary system of Wutong and further developed it.
