* Old English (c. 450-1150 AD): This period is characterized by the arrival of Germanic tribes (Angles, Saxons, Jutes) to Britain, bringing their languages with them. These languages evolved into Old English, the language of Beowulf and other early works.
* Middle English (c. 1150-1500 AD): The Norman Conquest in 1066 introduced French, which heavily influenced Old English, leading to the development of Middle English. This period saw the rise of Chaucer and other significant writers who helped shape the language.
* Early Modern English (c. 1500-1800 AD): The Renaissance, the invention of the printing press, and the exploration of the New World all contributed to the standardization and expansion of the language. William Shakespeare, a key figure in this period, is credited with using English in a way that influenced its development.
* Modern English (1800-present): This period saw the rise of British colonialism, which spread English to various parts of the world. This global usage, alongside technological advancements and the development of new dialects, continues to shape the language today.
Therefore, it's inaccurate to pinpoint a specific time and place for the "founding" of English. Instead, it's a gradual process of evolution and influence that continues to this day.
