'dismantler' originates from the verb 'dismantle', which comes from the Old French word 'desmanteler', where 'des-' meant 'apart' and 'manteler' meant 'to cloak or cover'.

'desmanteler' transformed into the English word 'dismantle', and eventually the noun form 'dismantler' was derived.

Initially, 'dismantle' meant 'to strip of covering', but over time it evolved into its current meaning of 'to take apart'.
