'revamp' originates from English, specifically the combination of the prefix 're-' and the verb 'vamp', where 're-' meant 'again' and 'vamp' meant 'to patch or mend'.

'revamp' was formed by adding the prefix 're-' to the older verb 'vamp' (itself from the noun 'vamp', the upper part of a shoe, which led to the verb sense 'to patch or mend'), and eventually came into modern use as 'revamp'.

Initially, it meant 'to patch up or mend' (often clothing or shoes), but over time it evolved into the current meaning of 'to renovate, redesign, or improve'.
