'responsibly' originates from Latin, specifically the word 'responsus,' where 'respondere' meant 'to answer or reply.'

'responsus' transformed into the Old French word 'responsable,' and eventually became the modern English word 'responsible,' from which 'responsibly' is derived.

Initially, it meant 'to answer or reply,' but over time it evolved into its current meaning of 'showing a sense of duty or accountability.'
