Established Through Popular Usage / Accepted Through Common Practice
Names are established through popular usage. Xunzi proposed this idea to describe how things are named. Xunzi believed that names fall into different categories, and every name is used to indicate a particular object. Which name is used to describe what or what kind of things is decided by the popularity of its use. When everybody accepts a name established by popular usage, it has become a fixed name for the particular object. This idea has also been used to describe the establishment of social norms.
There is no such thing as a name matches an object from the very beginning. All things are named in accordance with the popularity of their use by people. When everybody accepts a name, it is proper for the thing it refers to. Names that are not accepted or commonly used are not appropriate. Names are not originally meant to refer to a particular object; it is through popular use that a name comes to designate a particular thing. Once accepted through popular usage, a name has established its fixed association with the object it refers to. (Xunzi)
