With the development of the Internet, people are more free in speech and behavior, the generation and development of new Internet words tend to be mass-produced, and the concept of word model emerges as the times require. Li Yuming first proposed the concept of word model in 1999, that is, word model refers to various frameworks with the function of creating new words. Modulus refers to the invariable part of the morpheme in the word, which has the function of expressing the category of the word, or the characteristics of a certain kind of thing, or the characteristics of behavior. Die slots refer to vacancies in the word die. The model of the emerging word model 'XX zi' is 'zi', the constant element in the word; 'XX' is the mold slot, and various language units can be added according to the needs of the pragmatic style. 'XX Zi' can express the address of a certain type of person, the address of a social object or a self-proclaimed name, which is a kind of appellation expression. 'XX Zi' can also express personal attitudes, opinions and positions, with a relatively strong personal emotional color. The emergence of "XX Zi" is not only the function of internal language contact, but also the result of people's pursuit of individual expression in the external information age.
