Etymology: "Overactivate" is a plain compound: the prefix "over-" attached to "activate," meaning to set something in motion or make it active, with "over-" adding the sense of too much. The prefix itself is an old native element. It descends from Old English "ofer," which carried the sense of "above" or "beyond" and has roots reaching back to a Proto-Indo-European form meaning "up" or "over." The verb "activate" is the more interesting half. It traces back through Old French "actif" and Latin "āctīvus," from "āctus," the past participle of "agere," meaning "to do" or "to drive forward." The ancient Greek "energētikós," meaning "effective" or "active," shows the same notion of action in another language, and Latin "āctīvus" was formed from it with the suffix "-īvus" to mean "pertaining to action." English took "active" from Middle English "actyf," and "activate" was built from it with the suffix "-ate." Because "overactivate" is formed by the productive pattern of "over-" plus an existing verb, it is a transparent modern formation rather than a word with a dramatic history of its own.
