'impracticality' originates from the Latin word 'practicus,' meaning 'fit for action,' with the prefix 'im-' indicating negation.

'practicus' transformed into the Old French word 'practique,' and eventually became the modern English word 'practical,' with 'impracticality' forming as a negation.

Initially, it meant 'not fit for action,' and this meaning has largely remained the same in modern usage.
