Effort comes from the Old French 'esforz', which means to exert oneself or make an effort. The word is derived from the Latin 'exfortiare', where 'ex-' means out of and 'fortis' means strong. Thus, effort refers to the exertion of strength or energy to achieve something.
Think of 'ex-' meaning out of and 'fortis' meaning strong — this helps you remember that effort is about putting out your strength to achieve a goal.
