'righteously-done' originates from the combination of 'righteous' and 'done', where 'righteous' comes from Old English 'rihtwīs', meaning 'just' or 'virtuous', and 'done' is the past participle of 'do'.

'righteously-done' evolved from the Old English 'rihtwīs' and the past participle 'done', forming a modern compound adjective.

Initially, 'righteous' meant 'just' or 'virtuous', and 'done' meant 'completed'. Together, they convey the idea of an action completed in a morally right manner.
