Etymology: "Concluder" is about as plain as English word-building gets: the verb "conclude" with the agent suffix "-er" attached, giving a person or thing that concludes. The verb itself comes from Latin "concludere," meaning to shut up or enclose together, from "com-" (together) and "claudere" (to close). That physical sense of closing something in gives the verb its later meaning of bringing an argument or event to a close, and the noun simply names whoever performs that act. The noun is rare compared with its verb, and it appears mainly in discussions of decision-making, where someone must bring a debate or meeting to a final judgment. The sense of "concluding" as deciding or settling is what the suffix carries forward, so a concluder is the one who draws the matter to an end.
