'correctly' originates from Latin, specifically the word 'correctus,' where 'cor-' meant 'together' and 'rectus' meant 'straight.' 'Fitted' comes from Old English 'fittian,' meaning 'to fit or adapt.'

'correctus' transformed into the Old French word 'correct,' and eventually became the modern English word 'correct.' 'Fittian' evolved into the Middle English 'fitten,' leading to the modern English 'fit.'

Initially, 'correctly' meant 'in a straight or proper manner,' and this meaning has largely remained the same in modern usage. 'Fitted' originally meant 'to adapt or adjust,' which is consistent with its current meaning.
