'opulently' originates from Latin, specifically the word 'opulentus,' where 'op-' meant 'wealth' and '-ulentus' meant 'full of.'

'opulentus' transformed into the French word 'opulent,' and eventually became the modern English word 'opulent' through Middle English.

Initially, it meant 'full of wealth,' and this meaning has largely remained the same in modern usage.
