Nomenclature is a system of names or terms, or the rules for forming these terms in a particular field of arts or sciences.[1] 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 terms used in scientific and any other disciplines.[2]
