A name is a term used for identification by an external observer. They can identify a class or category of things, or a single thing, either uniquely, or within a given context. The entity identified by a name is called its referent. A personal name identifies, not necessarily uniquely, a specific individual human. The name of a specific entity is sometimes called a proper name (although that term has a philosophical meaning as well) and is, when consisting of only one word, a proper noun. Other nouns are sometimes called "common names" or (obsolete) "general names". A name can be given to a person, place, or thing; for example, parents can give their child a name or a scientist can give an element a name.
The word name comes from Old English nama; cognate with Old High German (OHG) namo, Sanskrit नामन् (nāman), Latin nomen, Greek ὄνομα (onoma), and Persian نام (nâm), from the Proto-Indo-European (PIE) *h₁nómn̥.[1] Outside Indo-European, it can be connected to Proto-Uralic *nime.
A naming convention is a set of agreed, stipulated, or generally accepted standards, norms, social norms, or criteria for naming things.
Parents may follow a naming convention when selecting names for their children. Some have chosen alphabetical names by birth order. In some East Asian cultures it is common for one syllable in a two-syllable given name to be a generation name which is the same for immediate siblings. In many cultures it is common for the son to be named after the father or a grandfather. In certain African cultures, such as in Cameroon, the eldest son gets the family name for his given name. In other cultures, the name may include the place of residence, or the place of birth.
Products may follow a naming convention. Automobiles typically have a binomial name, a "make" (manufacturer) and a "model", in addition to a model year, such as a 2007 Chevrolet Corvette. Sometimes there is a name for the car's "decoration level" or "trim line" as well: e.g., Cadillac Escalade EXT Platinum, after the precious metal. Computers often have increasing numbers in their names to signify the next generation.
Courses at schools typically follow a naming convention: an abbreviation for the subject area and then a number ordered by increasing level of difficulty.
