Endeavors or Endeavours
Both “endeavors” and “endeavours” are correct.
They mean serious efforts, attempts, or activities to achieve a goal.
- Endeavors → American English spelling
- Endeavours → British English spelling
Examples:
- She succeeded in all her professional endeavors.
- The charity supports educational endeavours worldwide.
There is no difference in meaning, only spelling.
The Origin of Endeavors or Endeavours
The word endeavour comes from Old French “en devoir”, meaning to put into duty or effort. It entered English in the 14th century, originally spelled endevour.
Over time, British English kept the “-our” ending, while American English simplified many spellings in the 1800s under the influence of Noah Webster, who promoted shorter forms.
That’s why we have:
- Colour → Color
- Labour → Labor
- Endeavour → Endeavor
This historical spelling split explains why both forms exist today.
