有的教师竟认为古今字就是通假字。为此,本文特提出简单易行的从本质上区分古今字与通假字的方法。一、已知古今字就是在某种意义上先后产生的形体不同的字,那么如何明确而简便地判别它,其方法就只需看古字与今字之间是否有其意义上的联系,有,则是,无,则非也。例如: (1)至莫夜月明。(《石钟山记》) (2)将军禽操,宜在今曰。(《赤壁之战》) (3)公输盘不说。(《公输》) 以上三例中的加点字,从汉字的发展史来看,我们不难认出都是古字;与后起的字相对来说,它们的今字则分别为(1)“暮”、(2)“擒”、(3)“悦”。之所以认为“莫 Some teachers actually think ancient and modern characters are common characters.
