Binomial nomenclature [SEP] Introduction
Binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also called a Latin name. The first part of the name – the "generic name" – identifies the genus to which the species belongs, while the second part – the specific name or specific epithet – identifies the species within the genus.
