通假字是古代汉语中很常见的一种文言用字现象。“通假”就是“通用、假借”的意思。凡两个读音相同或者相近、意义也相同的词，古代可以写这个，也可以写那个，叫做通用。例如“反”同“返”。 凡两个读音相同或者相近而意义毫不相干的词，古代可以借代，叫做假借。例如借用要求的“要”字来代替邀请的“邀”。例中的“反”字“要”字，统称为通假字；被替代的“返”字“邀”字，叫做本字或正字。用我们今天的话来说，通假字就是别字，其读音应按本字的音来读。熟悉文言文中常见的通假字，避免望文生义，有助于提高文言文的阅读水平。为此，笔者把七——九年级统编教材中的通假字依序汇总如下，以便同学们记背。

补释： “《兑命》‘学学半’”出自《尚书·说（yuè）命下》。《尚书》中的《说命》分上、中、下三篇，记录的全是关于傅说（yuè）的命辞或讲话。据此，有人认为“兑”（yuè），同“说”，指殷商时的贤相傅说。教材没把“兑”列入通假字。
