Is babe a verb proper noun?

A proper noun is usually the name of a person or a place: "babe" could only be a proper noun if it were someone's name, for example, the great Baseball player from many years ago named Babe Ruth ("Babe" was his nickname). Babe cannot be a verb, since a verb shows action, like "to run" or "to swim." The Word "babe" is an old version, or a shortened version, of the Word "baby", and it is just a common noun.
