本文从由港台借回的历史词汇、吸收港台特有的词语、吸收与普通话词语同义异形的港台词语三个方面 ,简略论述了改革开放以来普通话新词语对港台方言词语的吸收。这些吸收丰富了普通话词汇 ,增强了汉语的表达力 ;有些词语影响了汉语的纯洁。但哪些词语能在普通话词汇中站得住脚 ,哪些词语是昙花一现 ,要看能否约定俗成 ,这要历史来作结论。 This article briefly discusses the absorption of words from Hong Kong and Taiwan dialect since the reform and opening up, from the historical words borrowed by Hong Kong and Taiwan, the unique words of Hong Kong and Taiwan, the homophobic words of Hong Kong and Taiwan absorbed from Putonghua. These absorption enriches Mandarin vocabulary and enhances the expressive power of Chinese. Some words affect the purity of Chinese. But what words can stand in Putonghua vocabulary, which words are short-lived, depends on the conventions, it is the history to come to a conclusion.
