语言是人类重要的思维和交际工具，称谓语作为汉语语言中的重要组成部分，是一种特殊的语言符号。称谓语反映了特定语言环境中的人际关系，蕴含着一定的语言、文化内涵。“老师”这一称谓语，一般指的是从事教育事业的工作人员。但由于词语本身含义以及社会发展等多方面的影响，称谓语“老师”的语义、语用特征有所变化，由一个行业的专有称谓语逐渐泛化为一个指称对象扩大的称谓语，存在一定的泛化现象。本文从称谓语“老师”的起源、语义历时演变、语用特点等方面入手，结合社会语言学理论基础，对“老师”称谓语泛化现象及其成因进行浅析，并思考该词泛化现象所带来的问题。

Language is an important tool for human thinking and communication. As an important part of Chinese language, address forms are special language symbols. Address terms reflect the interpersonal relationship in a specific language environment, and contain certain linguistic and cultural connotations. The term "teacher" generally refers to the staff engaged in the cause of education. However, due to the influence of many aspects such as the meaning of the word itself and social development, the semantic and pragmatic characteristics of the address "teacher" have changed, and the exclusive address of an industry has gradually generalized to an expanded address of referential objects, and there is a certain generalization phenomenon. This paper starts from the origin, semantic diachronic evolution and pragmatic characteristics of the address "teacher", and combines the sociolinguistic theory basis to analyze the generalization phenomenon of the address "teacher" and its causes, and considers the problems brought by the generalization phenomenon.
