从《尚书》成语的产生过程和成语定义的发展演变中,我们可以发现成语的形成就是人们经常使用已有的语言词汇(基本是四字格的),使之逐渐定型的过程。而当前对成语定义的理解要么过于宽泛,要么过于片面,这从现有的成语词典的编撰可以看出。实际上,成语是一个历史概念和文化概念,成语最本质的特点是“习用”。此外,成语还应该具有历时性和共时性的内涵。 From the process of the generation of the Shangshu idiom and the development and evolution of the idiom definition, we can find that the formation of the idiom is the process by which people often use the existing linguistic (basically four-character) language to gradually shape it. However, the current understanding of the definition of idioms is either too broad or too one-sided, as can be seen from the compilation of existing idiom dictionaries. In fact, idioms are a concept of history and culture. The most essential feature of idioms is “habitual use.” In addition, idioms should also have diachronic and synchronic connotation.
