刘辰翁在其词《大圣乐》序中所言的“二语外率鄙俚”，并非反对词作语言的俚俗化而主张求雅。事实上，刘辰翁并不主张词作的语言应该崇雅黜俗；他所说的“牵雅颂入郑卫”，也应理解为“牵雅颂、入郑卫”，“牵雅颂”与“入郑卫”应是并列对等而非顺承的关系，所谓“入郑卫”，就是要求词的语言风格接近通俗的民间音乐，即俚俗化。而这一词学主张在他的诗文理论、学术思想和词作中均能得到映证。 Liu Chen-weng in his “Da Sheng” preface of “second language rate despicable”, not the objection to the language of vulgarization advocated elegant. In fact, Liu Chen Weng does not advocate the language of the word should be elegant and vulgar; he said “Qiao Ya Chung into Zheng Wei,” should also be understood as “lead Ya Chung, into Zheng Wei,” “ Zheng Wei ”should be parallel but not reciprocal reciprocal relationship, the so-called“ into Zheng Wei, ”is to require the language of the language style close to popular folk music, that is vulgar. And this word advocated in his theory of poetry, academic thought and the word can be reflected.
