'unworkably' originates from the English word 'unworkable', where 'un-' is a prefix meaning 'not', and 'workable' means 'capable of being worked or used'.

'unworkable' transformed from the Middle English word 'unwerkable', and eventually became the modern English word 'unworkable'.

Initially, it meant 'not capable of being worked', and over time it evolved into its current meaning of 'impractical or impossible to implement'.
