Etymology: "Acknowledger" is a straightforward formation: the verb "acknowledge" with the agent suffix "-er" added to name the one who does the acknowledging. The suffix itself has a long pedigree. It descends from Latin "-arius," which denoted a person connected with a job or activity, and it reached English through two routes. One came via Old French "-ier" into Middle English "-er," and the other, through Proto-Germanic and Old English "-ere," gave English a native agent ending that has since spread across countless verbs. The verb underneath is the more interesting half of the story. "Acknowledge" grew from the older "knowledge" with a prefix meaning "to" or "toward," so its basic sense is to bring something into a recognized relationship with oneself. An acknowledger, then, is someone who makes such recognition known, whether by a nod, a reply, or a formal statement of receipt. The noun is a transparent English coinage rather than a borrowing, and its meaning follows directly from its parts.
