成语是现代汉语的重要组成部分,它具有丰富的文化内涵和严密的结构形式。然而,经过长期地使用,不少成语的感情色彩不知不觉地发生了变化,有的由中性变为褒义;有的由中性变为贬义;有的发生褒贬转化。而在发生感情色彩变化的成语当中,一部分是由于汉字使用的不规范造成的:有的是由于使用通假字造成的;有的是近义词替换造成的;有的是同音形近字造成的,本文将探讨这些由于汉字使用不规范造成的成语感情色彩变化。 Idiom is an important part of modern Chinese. It has rich cultural connotation and strict structure. However, after long-term use, many idiomatic feelings have changed unconsciously.
