In lexicology, binomials are a two-part (binary) name.
In the nomenclature of biology , the scientific name for every type (species) of living being is always a binomial (binary or binomial nomenclature). Accordingly, the species name is made up of the name of the genus , which begins with a capital letter, and an addition for the respective species, which begins with a lower case letter. This addition is called " epithet " in botany and "species addition" in zoology . The combination of generic name and addition forms the name of the species as a nomenclature unit, i.e. the species name, which is written in italics . One example is the species name of humans, Homo sapiens . It consists of the generic name Homo and the additional species sapiens .
