'prompt' originates from Latin, specifically the word 'promptus,' where 'pro-' meant 'forward' and 'emere' meant 'to take.'

'promptus' transformed into the Old French word 'prompt,' and eventually became the modern English word 'prompt' through Middle English.

Initially, it meant 'ready or quick to act,' but over time it evolved into its current meaning of 'to cause or bring about an action.'
