'aggregate' originates from Latin, specifically the word 'aggregare', where 'ad-' meant 'toward' and 'gregare' meant 'to flock'.

'aggregare' transformed into the French word 'agrégat', and eventually became the modern English word 'aggregate' through Middle English.

Initially, it meant 'to flock together', but over time it evolved into its current meaning of 'to collect or gather into a mass or whole'.
