A trinomial name is a scientific name that consists of three parts: the genus, species, and subspecies. It is a system used to name organisms in biology, particularly in taxonomy. There are several synonyms for trinomial name, including trinominal nomenclature, triple name, ternary name, and tripartite designation. All of these terms describe the same concept of naming organisms with a three-part scientific name. Other related terms include binomial name (used for naming species with only two parts), taxonomic name, and Latin name. The use of trinomial names allows scientists to accurately identify and distinguish between different species and subspecies of organisms.
