Etymology: "Impactful" is a plain combination: the noun "impact" plus the suffix "-ful", meaning "full of" or "having the quality of." The noun "impact" comes from Latin "impactus," the past participle of "impingere," meaning "to drive against" or "to push into," built from "in-" and "pangere," "to fasten." So the original sense was physical: one object pressing or driving into another. English first used "impact" in its literal, physical sense of collision, and the figurative sense of a strong effect on people or events developed later from that image of forceful contact. "Impactful" follows the same path, taking the idea of a forceful collision and turning it into the idea of something that leaves a strong mark on what it touches.
