English is a West Germanic language related to Dutch, Frisian and German with a significant amount of vocabulary from French, Latin, Greek and many other languages.
English evolved from the Germanic languages brought to Britain by the Angles, Saxons, Jutes and other Germanic tribes, which are known collectively as Anglo-Saxon or Old English. Old English began to appear in writing during the early 8th century AD.
