'effort' originates from Old French, specifically the word 'esforz,' where 'es-' meant 'out' and 'forz' meant 'force.'

'esforz' transformed into the Middle English word 'effort,' and eventually became the modern English word 'effort.'

Initially, it meant 'outward force or exertion,' but over time it evolved into its current meaning of 'a determined attempt or exertion.'
