词汇是社会文化的灵感器,客观事物现象的发展变化能在词汇中得到灵敏而鲜明的反映。从词汇的历时系统中可以窥见不同的时代缩影。不同的词汇共时系统反映了不同国家、民族或地区的文化差异。词汇自身有一个自我发展自我淘汰的机制。这个机制的运转依赖的是词语或词语意义的使用频率和使用范围,即词汇的社会约定性。 Vocabulary is the inspiration of social culture. The development and change of the phenomenon of objective things can be sensitive and distinctly reflected in the vocabulary. From the vocabulary of the duration system can glimpse the different era microcosm. Different vocabulary synchronic systems reflect the cultural differences of different countries, ethnic groups or regions. Vocabulary itself has a self-development mechanism of self-elimination. The functioning of this mechanism relies on the frequency and scope of use of the word or phrase meaning, the social convention of the word.
