English language and sometimes also vocabulary, grammar and spelling—English-speakers from around the world are able to communicate with one another with relative ease. English is an Indo-European language and belongs to the West Germanic group of the Germanic languages. Old English originated from a Germanic tribal and linguistic continuum along the Frisian North Sea coast, whose languages gradually evolved into the Anglic languages on the British Isles, and into the Frisian languages and Low German/Low Saxon on the continent. The Frisian languages, together with which the Anglic languages form the Anglo-Frisian languages, are the closest living relatives of English. Low German/Low Saxon
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".
