音形义是构成词的三个要素。由于众所周知的原因,词汇中相当一部分词的要素是处于不稳定状态。在词形这个要素中,由于影响词形不稳定的原因不同,其说法也不同。如书写正确与否,有错字的说法;选择字形正确与否,有别字的说法;选择词形规范与否,有异形词的说法……此外还有繁简字 Formal meaning is the three elements that make up a word. For a well-known reason, the elements of a considerable part of the vocabulary are in an unstable state. In the element of the word form, the argument is different because of the different reasons that affect the form of the word. Whether the writing is correct or not, there is a typo saying; if the choice of the font is correct or not, there is a saying that there is a different word; if the word form is selected or not, there is a variant word.
