Etymology: The verb "actuate" comes from Medieval Latin "actuatus," the past participle of "actuare," meaning "to put into action." That Medieval Latin verb grew from the classical Latin "actus," "a doing or driving forward," which itself derives from "agere," "to drive, do, or set in motion." So the core idea from the start is movement and force, the sense of pushing something into doing its work. "Actuation" is formed by adding the suffix "-ion" to "actuate," a suffix English took through Old French from Latin "-tio" (genitive "-tionis"), used to make nouns of action or process. English has "-ion" nouns in abundance, so the ending here is ordinary; the interest lies in the stem, which carries the old Latin sense of driving something into motion.
