'aggrandiser' originates from French, specifically the word 'agrandir,' where 'a-' meant 'to' and 'grandir' meant 'to make larger.'

'agrandir' transformed into the English word 'aggrandize,' and eventually became the modern English word 'aggrandiser' through the addition of the suffix '-er.'

Initially, it meant 'to make larger or greater,' but over time it evolved into its current meaning of 'a person who seeks to increase their own power or status.'
