English and its Origins
English is a West Germanic language that originated from the Anglo-Frisiandialects brought to Britain by Germanic invaders from various parts of what is now northwest Germany and the Netherlands. Initially, Old English was a diverse group of dialects, reflecting the varied origins of the Anglo-Saxon kingdoms of England. One of these dialects, Late West Saxon, eventually came to dominate.

English changed enormously in the Middle Ages. Written Old English of 1000 AD is similar in vocabulary and grammar to other old Germanic languages such as Old High German and Old Norse, and completely unintelligible to modern speakers, while the modern language is already largely recognizable in written Middle English of 1400 AD. This was caused by two further waves of invasion: the first by speakers of the Scandinavian branch of the Germanic language family, who conquered and colonized parts of Britain in the 8th and 9th centuries; the second by the Normans in the 11th century, who spoke Old Norman and ultimately developed an English variety of this called Anglo-Norman. A large proportion of the modern English vocabulary comes directly from Anglo-Norman.

Cohabitation with the Scandinavians resulted in a significant grammatical simplification and lexical enrichment of the Anglo-Frisian core of English. However, this had not reached southwest England by the 9th century AD, where Old English was developed into a full-fledged literary language. This was completely disrupted by the Norman invasion in 1066, and when literary English rose anew in the 13th century, it was based on the speech of London, much closer to the center of Scandinavian settlement. Technical and cultural vocabulary was largely derived from Old Norman, with particularly heavy influence in the courts and government. With the coming of the Renaissance, as with most other developing European languages such as German and Dutch, Latin and Ancient Greek supplanted Norman and French as the main source of new words. Thus, English developed into very much a "borrowing" language with an enormously disparate vocabulary.
