成语是汉语词汇中一种长期沿用而定型化的固定词组或短句,它不仅有固定的结构形式,而且有确定的含义。历史遗留下来的许多成语,言简意赅,其精辟的含义往往隐含于字面意义之中,而不是其构成语素意义的简单相加,具有意义的整体性。 An idiom is a kind of fixed phrases or short sentences in the Chinese vocabulary that have been established for a long time. It has not only fixed structure but also definite meanings. Many idioms left behind by history are succinct and concise, and their implication is often implied in the literal meaning, rather than the simple summation of their constituent morpheme meaning, meaning of unity.
