'superbly' originates from Latin, specifically the word 'superbus,' where 'super-' meant 'above' and '-bus' was a suffix indicating quality.

'superbus' transformed into the Old French word 'superbe,' and eventually became the modern English word 'superb' through Middle English.

Initially, it meant 'proud or haughty,' but over time it evolved into its current meaning of 'excellent or impressive.'
