“字”,是指字形 ,是语言的书写符号体系 ;“词”,是能独立运用的最小的语言单位。在语言研究与运用中 ,字与词的内涵和外延之界限并不像想象中那样简单、明了。所以对字与词的辨别是极其必要的 ,而且很艰难。我们应该认识到这一点 ,并在使用中给以必要的区分和界定。 “Word” refers to the glyph and is the writing system of language. “Word” is the smallest language unit that can be used independently. In the study and application of language, the boundaries of the connotation and extension of words and words are not as simple and clear as imagined. Therefore, the identification of words and words is extremely necessary, and very difficult. We should recognize this and give the necessary distinction and definition in use.
