语言是人类社会中客观存在的现象,是人们表达思想、相互交际的工具。语言是以语音或字形为物质外壳,以词汇为建筑材料,以语法为结构规律而构成的体系。人们在社会历史发展过程中,逐渐形成一定的语言,如汉语、英语、俄语、日语等。但是,随着社会的发展变化,语言也会发展变化,如现代汉语就是从古汉语发展变化来的。 Language is an objective phenomenon in human society. It is a tool for people to express their ideas and communicate with each other. Language is a system in which speech or characters are the material shell, vocabulary is the building material, and grammar is the structural law. In the process of social and historical development, people gradually formed certain languages ​​such as Chinese, English, Russian, and Japanese. However, with the development of society, the language will also develop and change. For example, modern Chinese has evolved from ancient Chinese.
