'infeasibility' originates from the Latin word 'facere,' meaning 'to do or make,' combined with the prefix 'in-' indicating negation, and the suffix '-ibility' denoting capability.

'Infeasibility' evolved from the Old French word 'faisable,' meaning 'capable of being done,' with the prefix 'in-' added to denote the opposite.

Initially, it meant 'not capable of being done,' and this meaning has largely remained the same in modern usage.
