- Endeavours = British English spelling
- Both words have the same meaning
- Both are correct depending on the country or writing style

The meaning never changed. Only the spelling changed.

The word means:

- trying hard to do something
It can describe work, study, goals, projects, or personal efforts.
Examples:

- We endeavor to help others.
- Their team made great endeavors this year.
