Briton

Briton is a demonym for a person from Britain. In historical usage, it refers specifically to the Celtic-speaking inhabitants of the island of Great Britain during the late Iron Age and Roman periods, a group commonly called the Britons. In modern contexts, the term is less common as a daily self-identification and is more often found in ethnographic, literary, or historical writing.

Etymology and geography: The word Briton derives from the Latin Britannus, from Britannia, the Roman name for the island. The ancient Britons lived across what is now England, Wales, and parts of southern Scotland before and during Roman rule. They spoke Brittonic languages, a branch of the Insular Celtic family, and included tribes such as the Brigantes, Silures, and Votadini. After the Roman withdrawal and subsequent migrations, the term's geographic and political associations evolved alongside the formation of later British identities.

Modern usage: Today, "Briton" is largely a formal or historical term. The more common national demonym for residents of Britain is "British" or "a British person." "Briton" remains in use in official, ceremonial, or academic contexts, or when contrasting ancient Britons with modern inhabitants, and in some literary or scholarly works.
