In taxonomy, binomial nomenclature ("two-term naming system"), also called 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.
At the time when biologist Carl Linnaeus (1707–1778) published the books that are now accepted as the starting point of binomial nomenclature, Latin was used in Western Europe as the common language of science, and scientific names were in Latin or Greek: Linnaeus continued this practice.

Linnaeus's use of binomial nomenclature was anticipated by the theory of definition used in Scholasticism. Scholastic logicians and philosophers of nature defined the species human, for example, as Animal rationalis , where animal was considered a genus and rationalis (Latin for "rational") the characteristic distinguishing humans from all ...
As for Carl Linnaeus, he is widely recognized as the father of modern botanical nomenclature. Linnaeus introduced several key innovations in taxinomy. First, he applied binomial nomenclature, assigning each species a two-part Latin name, while also emphasizing detailed morphological characterization.
An alternative system of nomenclature, the International Code of Phylogenetic Nomenclature or PhyloCode has been proposed, which regulates the formal naming of clades. [ 65 ] [ 28 ] [ 9 ] Linnaean ranks are optional and have no formal standing under the PhyloCode , which is intended to coexist with the current, rank-based codes. [ 28 ]
Naming Authority Below the binomial name is the authority for that name — the first person to publish the name together with a description of the organism (or a reference to such a description). In this case the name Leptinotarsa decemlineata was first used by US naturalist Thomas Say (1787–1843) in the first volume of his American ...
