Celtic Britons

The Britons (also called Brythons) were the people who spoke a Celtic language known as Common Brittonic. They lived in Great Britain during the Iron Age, Roman Britain and Sub-Roman Britain after the Romans' departure from Britain. Following the arrival of the Anglo-Saxons, who occupied most what is now England, some of the Britons migrated to Wales, Cornwall and southern Scotland, while others moved to Armorica and renamed it Brittany. Those who remained were absorbed into Anglo-Saxon society.

 Name 
The name of the Britons in Modern English is borrowed in part from , and in part from Middle French (). During Roman Britain, the Latin word  and its plural, , took the place of the Romans' earlier word for a person from Britain, , and its plural, the . The people of Roman Britain, who were Romano-British, called themselves  in Latin. Other people also called the Britons thiatway:  the work of the Roman historian Procopius names them as Βρίττωνες (Brítonōnes) in Greek, and in Ireland, the Britons were called in Old Irish Bretain. Some modern Celtic languages also use that form for Britain was well: Scottish Gaelic has Breatainn, and Irish has Breatain.

The Anglo-Saxon historian Bede, writing in Latin, used the name , with the plural . The "e" vowel in this spelling could be taken from the Old English word for the Britons, Brett, which was also spelled Britt-, Bryt, Brytt-, Bret and Brit. The Anglo-Saxons probably took that name from the Romano-British. The  was a word used in Britain from the 5th century. Whether the Anglo-Saxons took the name Brett from the Latin name or from a British word of the same meaning is unknown. The Anglo-Saxons must have started using the word Brett by the 6th century. If they had copied the British word at a later time, the word would have had -th- instead of -t-, like the Welsh Brython, which literally means "Britons". In that case, the Old English copy would have had -þ- or -ð- instead of -tt-.

The name continued to be used in Middle English, with the spellings Bret, Brette and Brettis. Middle English also used the forms Brut and Brutt-, with the spelling copied from the name of Brutus of Troy. Mediaeval mythology was that Britain had been named after Brutus. In Early Modern English, the forms Brett and Britt were used. The spellings Bret and Brit were used in Scots.

The first professor of Celtic languages at the University of Oxford, John Rhys, was the first person to use the name "Brython" (from ) in academia as another English word for the Britons. He named the languages of the Britons "Brythonic" or the "Brythonic languages". Rhys used those names to be clear about what he meant because names like "British" could be ambiguous (have more than one meaning). "Brythonic" and "Brythonic languages" are names that are no longer common and are usually replaced by the names "Brittonic" and "Brittonic languages" in linguistics (the study of languages).
