nomenclature

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.

Naming "things" is a part of general human communication using words and language: it is an aspect of everyday taxonomy as people distinguish the objects of their experience, together with their similarities and differences, which observers identify, name and classify. The use of names, as the many different kinds of nouns embedded in different languages, connects nomenclature to theoretical linguistics, while the way humans mentally structure the world in relation to word meanings and experience relates to the philosophy of language.
