When did middle English start?

Middle English is generally considered to have begun around 1150 AD, with the Norman Conquest of England in 1066 often cited as a key event leading to its emergence.

Here's why:

* Norman Conquest: The Normans brought their French language to England, which greatly influenced the English language. This influence led to a blend of Old English and Norman French, creating the foundation for Middle English.

* Linguistic Changes: Over time, these languages interacted and changed, with French words being borrowed and incorporated into English. The grammar and pronunciation of English also evolved.

* Literary Developments: The emergence of Middle English coincided with the development of significant literary works, such as *Canterbury Tales* by Chaucer, written in the late 14th century.

However, it's important to note that Middle English didn't appear suddenly. It's more of a gradual transition from Old English, with a period of overlap and mixed language use.
