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.

binomial authority; binomial nomenclature (also "binominal") trinomial nomenclature (also "trinominal") hybrid name (botany): either two parent binomials, separated by a "×" (q.v.) or a given binomial, with or without an intercalated "×" chresonym published usage of a name heterochresonym; orthochresonym; taxon (plural "taxa")
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.
Living organisms are known by scientific names.These binomial names can vary greatly in length, and some can be very short; genus or species names composed of only one letter are not allowed by any of the nomenclature codes, but any combination of two letters and above can be valid if it has not been previously used.
In botanical nomenclature, "name" always refers to the whole name (of a species or otherwise), whereas in zoological nomenclature it can refer to either part of the binomen. Thus Hedera helix (common ivy, English ivy) is the name of the species; Hedera is the name of the genus; but helix is called the specific epithet, not the specific name.
A taxobox (short for taxonomy infobox) is a table found on Wikipedia articles setting out the currently largely-accepted scientific classification of an organism or group of organisms. Note that there is sometimes taxonomic debate on the status and name of a taxon. As of June 2011, the English Wikipedia contained more than 180,000 taxoboxes.
