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. Over time, the language was influenced by Old Norse with the Viking invasions and later by Norman French following the Norman conquest, and has continued to change with influences from Latin, Greek, and languages from around the world due to British colonial expansion. The document provides context around the development of English into a global language used by hundreds of millions of people today.
