Origin of aggregate

First recorded in 1375–1425; late Middle English, from Latin aggregātus (past participle of aggregāre ), equivalent to ag- ag- + greg- (stem of grex “flock”) + -ātus -ate1

word story For aggregate

All three parts of speech of aggregate (adjective, noun, verb) come directly from Latin aggregāt-, the stem of aggregātus, the past participle of aggregāre.
Aggregāre is a compound of ag-, a variant of the prefix ad- “to, toward,” and a derivative of the noun grex (inflectional stem greg- ) “flock, herd, band, troop, company”; aggregāre therefore means “to make (people) flock together, enter into association, join”—the association with grex “flock” is clear.
The Latin forms come from the Proto-Indo-European root ger-, gere- “to gather, collect,” which appears in Celtic, Germanic, Baltic, and Slavic. Probably the most important derivative of ger-, gere- for the history of Western culture is the Greek noun agorá “meeting, assembly, market, marketplace, trade, traffic,” especially the Agora in Athens, the chief marketplace and center of the city’s civic life.
