“任”在上古时期是一个使用频率较高的词,本义为“抱”。从上古到战国秦汉再到唐宋,任经历了一系列发展演变历程,直接和间接地引申出许多新义,到现代,“任”仍作为一个高频词为人们熟悉并使用,但“任”的本义“抱”却从它众多引中义中消失了。变化的原因主要有两方面：一是社会的发展影响了“任”的词义演变；二是词类系统里词和词之间的相互联系和制约导致“任”的发展变化。 “Ren” in ancient times is a frequently used word, the original meaning of “hug.” From ancient times to the Qin and Han dynasties in the Warring States period and then to the Tang and Song dynasties, he underwent a series of developmental changes and directly or indirectly heralded many new meanings. In modern times, Ren is still familiar and used as a high-frequency word, but “Ren” The original meaning of “hug” disappears from its numerous references. There are two main reasons for the change: First, the development of society affects the evolution of the meaning of “Ren”; secondly, the interdependence and restriction between words and terms in the part of speech system lead to the development and change of “Ren”.
