The document discusses the linguistic roots and evolution of the English language from Old English to modern English. It traces the influences of Celtic, Latin, Scandinavian, French and Germanic languages over time. Key events that shaped English include the arrival of Romans in Britain in 43 AD, the Norman conquest of 1066 which introduced more French words, and the Great Vowel Shift between 1400-1700 that changed pronunciation. The printing press helped standardize spelling. Modern English incorporated many new words from other languages and places.
