In the digital era, people’s life experience has been greatly expanded. With the rapid development of network technology, a large number of new words have emerged. Internet buzzwords not only reflect the latest social dynamics, but also reveal people’s cultural psychology and trends, thus possessing significant value for academic research.In 2023, the term “dazi” (a casual companion) was selected as one of the Top Ten Buzzwords, and many derivative combinations have appeared, such as “meal dazi”, “restroom dazi”, “travel dazi”, and so on. “Dazi” is not merely a substitute for intimate relationships, but rather a beneficial supplement to stable relationships. It embodies young people’s respect for their true inner feelings and their willingness to maintain an open social attitude.This paper mainly studies the word “dazi” from four aspects: grammatical, pragmatic, semantic features and its formation motivation. It aims to provide normative guidance for the popular word “dazi” and ensure its healthy development without violating the laws of language evolution.
