Here's a breakdown:
* Angles: This tribe, along with the Saxons and Jutes, invaded and settled in Britain after the Romans left.
* Angleland: The land where the Angles settled became known as "Angleland," which eventually evolved into "England."
* Old English: The language spoken by the Angles, Saxons, and Jutes became known as "Old English," which is the ancestor of modern English.
Therefore, the language spoken by the people of England, a land named after the Angles, came to be called "English."
