Etymology: "Vociferator" is a plain English formation: it combines "vociferate," a verb meaning to shout or cry out loudly, with the agent suffix "-or," which turns a verb into a noun for the person who performs the action. The result names someone who does the vociferating, much as a "narrator" narrates or an "executor" executes. The verb underneath is the more interesting part. "Vociferate" comes from the Latin "vociferari," built from "vox" (voice) and "ferre" (to bring forth, to bear), so the sense is literally "to bear the voice loudly." The suffix "-or" is the same ending found in older English agent nouns borrowed from Latin, so "vociferator" follows a familiar pattern rather than being a special coinage.
