aggregate: [15] Etymologically, aggregate contains the notion of a collection of animals. It comes from greg-, the stem of the Latin noun grex ‘flock, herd’ (also the source of gregarious). This formed the basis of a verb aggregāre ‘collect together’, whose past participle aggregātus passed into English as aggregate. Latin grex is related to Greek agorā ‘open space, market place’, from which English gets agoraphobia.
