'compliment' originates from Latin, specifically the word 'complēmentum,' where 'complēre' meant 'to fill up or complete.'

'complēmentum' transformed into the French word 'compliment,' and eventually became the modern English word 'compliment' through Middle English.

Initially, it meant 'to complete or fulfill,' but over time it evolved into its current meaning of 'to express praise or admiration.'
