Nomenclature is a system of names or terms, or the rules for forming these terms in a particular field of arts or sciences.The principles of naming vary from the relatively informal convection of everyday speech to the internationally agreed principles, rules and recommendations that govern the formation and use of the specialist terms used in scientific and any other disciplines
IN BIOLOGY
Nomenclature, in biological classification system of naming organisms. The species to which the organism belongs is indicated by two words, the genus and species names, which are Latinized words derived from various sources. This system, which is called the Linnaean system of binomial nomenclature was established in the 1750s by Carlos . Subsequent to the work of Linnaeus, a proliferation of binomial names took place as new species were established and higher taxonomic categories were formed, with the result that by the late 19th century there was much confusion in the nomenclature of many groups of organisms. In the 20th century, the establishment of rules by international committees in the fields of zoology, botany, bacteriology, and virology has done much to clarify the situation.
