International English English language evolved in England, from a set of West Germanic dialects spoken by the Angles and Saxons, who arrived from continental Europe in the 5th century. Those dialects came to be known as "Englisc" (literally "Anglish"), the language today referred to as Anglo-Saxon or Old English (the language of the poem "Beowulf"). However, less than a quarter of the vocabulary of Modern English is derived from the shared ancestry with other West Germanic languages because of extensive borrowings from Norse, Norman, Latin, and other languages. It was during the Viking invasions of the Anglo-Saxon period that Old English was
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".
