In recent years, the research on the new word family of modern Chinese and some morphemes with affixation like tendency has been continuous. Most of the research focuses on word formation, syllable characteristics, and the components in the sentence. However, the semantic evolution of some affixes is not very clear, or because the morpheme meaning of this type of affixes is relatively diverse, which leads to the fact that several word families with different sources and types seem to be confused. This brings some troubles to some specific language teaching practice. The new words “X寶” is such a typical example, Although it seems that the morphology is the same and “X” and “寶” form the noun of the fixed structure, in fact, “寶”, as a common morpheme, has various morpheme meanings. Therefore, “X寶” word family also has several different sources and types. This paper starts with the semantic evolution of the word “寶” and makes a classification study of the new words of “X寶”. This paper argues that the sources of new words of “X寶” in A (financial APP name) and B (general entity product name) are different from those in C (nickname of people) and D (gem). They not only have obvious differences in semantics, but also in syllable number, word formation, productivity and so on. Finally, this paper discusses the motivation of the extension of the new meaning of “寶” and the generation of the new words of “X寶” from the perspective of external and internal factors of language. Thus, the author summarizes several types of word families of “X寶” in modern Chinese.

This paper discusses and analyzes the new meaning of the word ‘Geng’ (梗) which has appeared in recent years, and concludes that there are two new meanings of the word ‘Geng’ (梗) in recent years: one, ‘laugh point’, and the other ‘the plot’. The latter developed from the former which had come from the misappropriation of the word ‘Gen’ (哏). So this view is held by the ‘Geng’ (梗) and ‘Gen’ (哏) as the font under the guise of relations, glyph is ‘Geng’ (梗) under the guise of for the ‘Gen’ (哏) because use frequency is higher, after ‘Geng’ (梗) also gradually obtained the meaning of ‘Gen’ (哏), and then the first meaning as the change of use requirements, the semantic also expanded, developed what ‘Gen’ (哏) does not have second meaning. Then this paper analyzes the current situation of the use of the two new meanings of ‘Geng’ (梗), and concludes that, according to them, the corpus of new words of ‘X梗’ can be divided mainly into A and B types. In addition to the semantics, the two categories also have obvious differences in the number of syllables, word formation, productivity and other aspects. Moreover, the emergence of some ‘梗 X’ structures, namely C type, also shows the strong vitality of the new meaning of ‘Geng’ (梗).
