The science of naming living organisms is called Taxonomy.
The two-word system is called binomial nomenclature
Binomial Nomenclature
binomial nomenclature
The first word in a two-word scientific name of an organism identifies the genus to which the organism belongs. The second word denotes the species within that genus. This naming system is known as binomial nomenclature and was developed by Carl Linnaeus.
A noun is called a naming word because a noun is a word for (what you call) a person, a place or a thing.
Binomial Nomenclature. In other words, using an organisms Genus and Species to classify them into categories.
Genus
Scientific names follow a specific set of rules. Scientist use a two-name system called a binomial naming system. Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species.
The two word system that was devised for naming organisms is called "binomial nomenclature." "Binomial" is defined as "two names." ~ Kimberlee
There is not a specific system of naming federal agencies. Most of them are acronyms. Perhaps "specific" would be a good word.
Two-word name was first developed by Carolus Linnaeus. He chose two words from Latin for naming an organism. First word referred to Genus of organism and second word referred to species of organism.
