Old English is a West Germanic language, developing out of Ingvaeonic (also known as North Sea Germanic) dialects from the 5th century. It came to be spoken over most of the territory of the Anglo-Saxon kingdoms which became the Kingdom of England.

Legal English the Law of Æthelberht. Following the Norman invasion of England in 1066, Anglo-Norman French became the official language of legal proceedings in England for a period of nearly 300 years until the Pleading in English Act 1362 (and continued in minor use for another 300 years), while Medieval Latin was used for written records for over 650 years. Some English technical terms were retained, however (see Anglo-Saxon law: Language and dialect for details). In legal pleadings, Anglo-Norman developed into Law French, from which many words in modern legal English are derived. These include "property", "estate", "chattel", "lease", "executor", and "tenant".
