Old English ("Ænglisc, Anglisc, Englisc") is the earliest form of the English language. It was brought to Britain by Anglo-Saxon settlers, and was spoken and written in parts of what are now England and southeastern Scotland until the mid-12th century, by which time it had evolved into Middle English. Old English was a West Germanic language, closely related to Old Frisian and Old Saxon. The language was fully inflected, with five grammatical cases, three grammatical numbers and three grammatical genders. Over time, Old English developed into four major dialects: Northumbrian, spoken north of the Humber; Mercian, spoken in the Midlands; Kentish, spoken in Kent; and West Saxon, spoken across the south and southwest. All of these dialects have direct descendants in modern England. Standard English developed from the Mercian dialect, as it was predominant in London.
