The invading Germanic tribes spoke similar languages, which in Britain developed into what we now call Old English. Old English did not sound or look like English today. Native English speakers now would have great difficulty understanding Old English. Nevertheless, about half of the most commonly used words in Modern English have Old English roots. The words be, strong and water, for example, derive from Old English. Old English was spoken until around 1100.
The languages spoken by the Germanic peoples who initially settled in Britain were part of the West Germanic branch of the Germanic language family. They consisted of dialects from the Ingvaeonic grouping, spoken mainly around the North Sea coast, in regions that lie within modern Denmark, north-west Germany and the Netherlands. Due to specific similarities between early English and Old Frisian, an Anglo-Frisian grouping is also identified.
These dialects had most of the typical West Germanic features, including a significant amount of grammatical inflection. Vocabulary came largely from the core Germanic stock, although due to the Germanic peoples' extensive contacts with the Roman world, the settlers' languages already included a number of loanwords from Latin.[3] These included the predecessor of Modern English wine, which had been borrowed into early Germanic from the Latin vinum.
