Here's a breakdown:
* Angles: They were a group of people from the Angeln region of what is now Denmark. They settled in the eastern and northern parts of Britain, which became known as "Angleland" or "Englaland".
* Old English: The language spoken by the Angles and other Germanic tribes in Britain was called "Old English" or "Anglo-Saxon". This language evolved from the various Germanic dialects spoken by the invaders.
* Evolution of the Name: The name "England" and the term "English" were derived from "Angleland" and "Angle". Over time, the language of England became known as "English" due to the dominant influence of the Angles.
While other tribes like the Saxons and Jutes also played a role in shaping English, the Angles became the most prominent and their name became synonymous with the language and the people of the region.
