词是语言中最小的独立运用的意义单位。词的本质是词义。词义就是词所表达的意义,是客观存在于人们意识中的概括的反映。对词义的了解,是语言的交际功能发生作用的极其重要的前提之一。 Words are the smallest units of meaning in language that are used independently. The essence of words is meaning. Word meaning is the meaning expressed by the word, which is a reflection of the generalization of the objective existence in people’s consciousness. The understanding of meaning is one of the most important preconditions for the communicative function of language to take effect.
