Binomial nomenclature (also called binominal nomenclature or 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. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, binominal name or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus Homo and within this genus to the species Homo sapiens. The formal introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work Species Plantarum in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book Pinax theatri botanici (English, Illustrated exposition of plants) many names of genera that were later adopted by Linnaeus
The application of binomial nomenclature is now governed by various internationally agreed codes of rules, of which the two most important are the International Code of Zoological Nomenclature (ICZN) for animals and the International Code of Nomenclature for algae, fungi, and plants (ICN). Although the general principles underlying binomial nomenclature are common to these two codes, there are some differences, both in the terminology they use and in their precise rules.
In modern usage, the first letter of the first part of the name, the genus, is always capitalized in writing, while that of the second part is not, even when derived from a proper noun such as the name of a person or place. Similarly, both parts are italicized when a binomial name occurs in normal text. Thus the binomial name of the annual phlox (named after botanist Thomas Drummond) is now written as Phlox drummondii.
In scientific works, the "authority" for a binomial name is usually given, at least when it is first mentioned, and the date of publication may be specified.

Binomial nomenclature or Binomial system of classification is a formal system of assigning names to living organisms composed of two parts. It is simply called as binomen or scientific name. As the word binomial which is Latin in origin means ‘‘two part name’’, so binomial nomenclature is simply a system of classification in which an organism is assigned a name comprising of two parts, the first part consists of the Genus (which is usually a noun) to which the microbe or any other organism belongs and second part comprises of a specific epithet (usually an adjective) that further describes the qualities of the generic name. As a whole, these two words account for a species name and are usually derived from Latin and Greek languages.
For example, the common human microbiome, Escherichia coli found in the gut. The first part of the binomial, Escherichia, is the name of the genus to which this microbe belongs and the second part or the specific epithet is, coli, an attribute which is derived from the word colon from where it was found the very first time.
The value of the binomial nomenclature comes from several things. It saves words because it replaces long descriptions, it is used everywhere, and the names are unique and stable. The system ended the use of local common names, which was the source of much confusion. When science was done by just a few European countries their common names for species were well-known. But as it happened, the common names in all countries was rather different. The same name might be used for more than one species, and several species given the same name. In the Linnaeus system, everyone uses the same name for the same species. Linnaeus chose Latin names. First, because it avoided competitive nationalism; second because most educated people in his day learnt Latin.
The system has been a great success, but it does have some problems. It is not always clear what is a species and what is not. Although many species are quite clear, some are put nto one species by some biologists, and into several species by others. Linnaeus himself noticed that species were not always distinct.Today we know something about why this is so. In practice, international committees make decisions about naming species in difficult cases.
a system of nomenclature in which each species of animal or plant receives a name of two terms of which the first identifies the genus to which it belongs and the second the species itself.
The binomial nomenclature system combines two names into one to give all species unique scientific names. The first part of a scientific name is called the genus. The second part of a species name is the specific epithet.
