A name (etymology: from OE nama; akin to OHG namo, Latin nomen, an Greek όνομα (onoma), ultimately from PIE: *nomn- ) is a label for a human or animal, thing, place, product (as in a brand name) and even an idea or concept, normally used to distinguish one from another. Names can identify a class or category of things, or a single thing, either uniquely, or within a given context. A personal name identifies a specific unique and identifiable individual person. The name of a specific entity is sometimes called a proper name (although that term has a philosophical meaning also) and is a proper noun. Other nouns are sometimes, more loosely, called names; an older term for them, now obsolete, is "general name".
