The document discusses the history and evolution of the English language from its origins as Anglo-Frisian dialects brought to Britain by Anglo-Saxon settlers in the 5th century AD. It details how Old English emerged as the dominant language by the 7th century and later transformed into Middle English after the Norman conquest of 1066, when the language absorbed elements from Old Norse and Norman French. The document also briefly examines how English continued to change and develop over time through the influence of other languages and as a result of social and political changes.
