Binomial nomenclature is a formal system for naming species using two Latinized names - the generic name for the genus and the specific epithet for the individual species. This two-part naming convention provides uniqueness, universality, and stability for scientific classification and communication by establishing a single, standardized name for each organism. The system ensures each species has one agreed-upon name to facilitate access to all known information about that taxon.

1. Binomial nomenclature

2. Definition
Binomial nomenclature ("two-term naming system"), also called binominal
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.

3. 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.
For example, humans belong to the genus Homo and within this genus to the
species Homo sapiens

5. Objectives

Uniqueness. The name of a particular organism gives one immediate access to
all of the known information about the particular taxon. Every name must be
unique because it is the key to the entire literature relating to the species or
higher taxon in question. If several names have been given to the same taxon,
there must be a clear-cut method whereby it can be determined which of the
names has validity
 Universality. Scientific communicationwould be made very difficult if we had
only vernacular names for taxa in innumerable languages in order to
communicate with each other. To avoid this we have adopted an international
agreement for a single language (Latin) and a single set of names for
biological diversity to be used on a worldwide basis.
 Stability. As recognition symbols of diversity, names of organisms would lose
much of their usefulness if they were changed frequently and arbitrarily.
