We added aggregate to our flock of Latin borrowings in the 15th century. It descends from aggregāre ("to cause to flock together" or "to join together"), a Latin verb made up of the prefix ad- (which means "to," and which usually changes to ag- before a g) and greg- or grex (meaning "flock, herd, or group"). Greg- also gave us congregate, gregarious, and segregate. Aggregate is commonly employed in the phrase "in the aggregate," which means "considered as a whole." Aggregate also has some specialized senses. For example, it is used to describe a mass of minerals formed into a rock, and materials like sand or gravel that are used to form concrete, mortar, or plaster.
