'practicability' originates from the Latin word 'practicabilis,' where 'practicare' meant 'to practice.'

'practicabilis' transformed into the French word 'praticable,' and eventually became the modern English word 'practicable,' from which 'practicability' is derived.

Initially, it meant 'capable of being done or put into practice,' and this meaning has largely remained the same in modern usage.
