Legal English the history of the development of English as a legal language. In prehistoric Britain, traditional common law was discussed in the vernacular (see Celtic law). The legal language and legal tradition changed with waves of conquerors over the following centuries. Roman Britain (after the conquest beginning in AD 43) followed Roman legal tradition, and its legal language was Latin. Following the Roman departure from Britain circa 410 and the Anglo-Saxon invasion of Britain, the dominant tradition was instead Anglo-Saxon law, which was discussed in the Germanic vernacular (Anglo-Saxon, Old English), and written in Old English since circa 600, beginning with
Anglo-Norman language (corporation), (court)). Place-names in Norman are few, but there is Buttevant (from the motto of the Barry family: , "Push to the Fore"), the village of Brittas (from the Norman , "boarding, planking") and the element "Pallas" (Irish , from Norman , "boundary fence": compare palisade, The Pale). Others exist with English or Irish roots, such as Castletownroche, which combines the English "Castletown" and the Norman , meaning rock. Only a handful of Hiberno-Norman-French texts survive, most notably the "The Song of Dermot and the Earl" (early 13th century) and the Statutes of Kilkenny (1366).
