新词汇的出现总是晚于事物、现象的变化,于是就出现了语言表达上的空缺。而大事件、突发事件刺激引发的新词往往具有形象生动、诙谐、概括力强的特点,因此能迅速流行,而且还常常引出系列的新词串。事件的刺激是这些词产生的外因,语言表达的缺位是内因,原有语素和构词法是基础。 The emergence of new words is always later than things, the phenomenon of change, so there has been a gap in language expression. However, new words triggered by major events and unexpected stimuli often have the characteristics of vivid, humorous and strong summarization, therefore they can be popular rapidly and often lead to new series of new words. The excitement of events is the external cause of these words. The absence of language expression is the internal cause. The original morphemes and the word formation are the foundation.
