Etymology: Hyperaggressive is a plain modern formation: the prefix "hyper-" joined to "aggressive." The prefix comes from Ancient Greek "hyper," meaning "over" or "beyond," which was also the source of the Latin "super" and English "over" in its excessive sense. In Greek it was a free word, but in English it became a productive prefix, attached to existing adjectives to mean "to an extreme degree," as in "hyperactive" and "hypersensitive." The base word traces back through Latin "aggressus," the past participle of "aggredi," meaning "to step toward or attack." That verb combined "ad-" ("to") with "gradi" ("to walk" or "step"), so the original sense was simply moving toward something. The English noun "aggression" came from it, and "aggressive" was formed by adding the suffix "-ive," which came into English through Old French from Latin "-ivus." The combination of the two parts is recent. The word is a compound of English elements, so it has no ancient history of its own; it simply stacks an intensifying prefix onto a word that already meant "forceful, quick to attack."
