Definition
A proper name (or just name) is a symbol used to identify a particular object uniquely.

The terms individual constant is often seen, as are (particularly when applied to a number) constant and parameter.

In contrast with natural language, a proper name has a wider range than being the particular identifying label attached to a person, or a place, etc.

For example, "sloth" is a proper name for the concept of being lazy. "Rain" is the proper name for the meteorological phenomenon of water falling from the sky.
