Etymology: The word "verifier" is a plain formation: the verb "verify" with the agent suffix "-er" attached, meaning one who verifies. "Verify" itself came into English from Old French "verifier", which goes back to medieval Latin "verificare", from Latin "verus" ("true") and "-ficare" ("to make"). So the core idea is "to make true", and a verifier is literally someone who makes or shows something to be true. The suffix has a longer pedigree than the verb. The "-er" ending descends from Old English "-ere", which in turn traces back through Latin "-arius", a suffix that marked a person connected with a trade or role. English adopted the same pattern with native and borrowed stems alike, so "verifier" joins a large family of agent nouns that includes "writer" and "reader", both built on the same ending.
