多义词和同形异义词的明显区别在于二者的起源、词源学说及词义的相关原则。他们当中有的可通过区分其特征加以辨别,但仍有一些词汇无法用上述方法识别。英语学习者要掌握其特殊的语义特征,将二者熟练地运用到日常生活及文学作品之中。 The obvious difference between polysemy and homonymy lies in the origin, etymology and related principles of the word meaning. Some of them can be distinguished by distinguishing their characteristics, but there are still some words that can not be identified by the above method. English learners should master their special semantic features and apply both to daily life and literary works.
