Etymology

Origin of aggregate

Explanation

To aggregate is to collect many units into one. If you're writing a novel, you might create a character who is an aggregate of five or six real people. Aggregate comes from the Latin verb aggregare, which means to add to. As a verb it means to collect into a mass or whole.
