Wittgenstein refined and proposed the theory of family resemblance (Family Resemblance) based on the traditional theory of categories. He believed that the members of a category need not have all the properties of the category, but rather an AB, BC, CD, DE-style family similarity relationship, that is, a member has at least one or more **** the same properties as other members. The members of a category do not have exactly the same properties; they belong to the same category by family resemblance. And the category has no fixed and clear boundaries, is with the development of society and the improvement of human cognitive ability and the continuous formation and change and development.

Family resemblance is reflected in many aspects of language study, such as lexical categories, syntax, rhetoric, and phonology. As an example, the family similarity of word category categories is a metaphorical expression. It means: individual words belonging to the same word class have different degrees of similarity in grammatical properties, some of them have more similarity in distribution and they become typical members of this class, while some words have less similarity in distribution with other words and they become atypical members of this class. In other words, word classes are prototype categories that have been generalized on the basis of similarities in grammatical properties between words.
