语言是一个自足系统,它本身具有自我调节功能。纯洁性不是语言的本质属性,语言的发展有它自身的规律。许多国家的语言纯洁运动都收效甚微,一个国家语言的发展绝不是人为的。但语言是可以规范的,遵循语言发展规律的语言规范化工作才可以让一个国家的语言健康积极地发展。衡量语言规范化工作是否有效的一个标准是语言的交际值。言语交际是语言纯洁与语言规范的根本目的。 Language is a self-contained system that has its own self-regulating function. Purity is not the essential attribute of language. The development of language has its own laws. In many countries, the pure language movement has had little effect. The development of a national language is by no means artificial. However, language can be standardized, and the language standardization that follows the law of language development can make a country’s language develop healthily and actively. A measure of the effectiveness of language standardization work is a language of communication values. Verbal communication is the fundamental purpose of language purity and language norm.
