Abbreviation is a common language phenomenon. People always want to transform and simplify some complex language units because of their common use, so they omit some morphemes and condense the original meaning into the combination of those morphemes that have been preserved. Abbreviated language units are like words but not ordinary words; Phrases that are like phrases but not common can be collectively referred to as "abbreviations".

The appearance of abbreviations. With the language reflecting the development of social life becoming more and more complex, the contradiction between quickness and convenience in communicating with people in language intensifies the phenomenon of language abbreviations. Especially since the founding of New China, the rapid development and changes of politics and economy and the large number of abbreviations in modern Chinese just illustrate this point. For example, since the reform and opening up, there have been a number of words reflecting export-oriented economic activities, such as processing with supplied materials, processing with drawings, assembling with supplied parts, and compensation trade. People think it is too complicated and inconvenient to use, so it is simply called "three supplies and one supplement".

Structural forms of abbreviations. It depends on the characteristics of each morpheme in a word, such as the expression function and word formation function of morphemes. Therefore, the abbreviations of words should not be arbitrary. For example, in the two commonly used phrases of "science and technology" and "financial economy", the four morphemes of "learning", "technology", "politics" and "classics" are omitted, and the original meanings can still be maintained. On the other hand, if the four morphemes of "science", "technology", "finance" and "economy" are omitted, the original intention cannot be maintained and the abbreviation cannot be formed. In addition, the use of abbreviations is also related to the context. For example, the Youth League can be abbreviated as "Youth League", "Youth League" and "Youth League", and different choices can be made according to different contexts.

Abbreviations are characterized by conciseness and large amount of information. Some abbreviations have certain timeliness, which were commonly used ten years ago, but may no longer be used today. This is a problem for people with insufficient life experience. Some abbreviations are so regional that Shanghainese, who are commonly used by Beijingers, may not use them or understand their meanings. Many abbreviations are also very professional or professional, and people who are not in this major or industry often feel puzzled. Many abbreviations are produced under specific historical conditions, reflecting the social life content in a specific historical period, even major historical events or major political and economic changes. Although it is often used, it is not easy to explain it clearly because of too much content and complex background.
