'recalibrate' originates from the prefix 're-' meaning 'again' and the word 'calibrate' which comes from the Latin 'calibrāre', meaning 'to measure'.

'calibrāre' transformed into the French word 'calibrer', and eventually became the modern English word 'calibrate', with 're-' added to form 'recalibrate'.

Initially, it meant 'to measure again', but over time it evolved into its current meaning of 'to adjust or mark again for accuracy'.
