'adorn' originates from Latin, specifically the word 'adornare,' where 'ad-' meant 'to' and 'ornare' meant 'furnish or decorate.'

'adornare' transformed into the Old French word 'aourner,' and eventually became the modern English word 'adorn' through Middle English.

Initially, it meant 'to furnish or decorate,' and this meaning has largely remained the same in modern usage.
