'adular' originates from Latin, specifically the word 'adulārī,' where 'ad-' meant 'to' and 'ulārī' meant 'to flatter.'

'adulārī' transformed into the French word 'aduler,' and eventually became the modern English word 'adular' through Middle English.

Initially, it meant 'to flatter excessively,' and this meaning has largely remained the same in modern usage.
