Nomenclature (, ) is a system of names or terms, or the rules for forming these terms in a particular field of arts or sciences. The theoretical field studying nomenclature is sometimes referred to as onymology or taxonymy. The principles of naming vary from the relatively informal conventions of everyday speech to the internationally agreed principles, rules, and recommendations that govern the formation and use of the specialist terminology used in scientific and any other disciplines.
