Etymology: "Abater" is a plain English formation: the verb "abate" with the agent suffix "-er" attached, giving a word for something or someone that abates. "Abate" itself came into English through Old French, from the verb "abattre," meaning "to beat down" or "to strike down," built from "a-" (toward) and "battre" (to beat). Its earliest sense was physical: to knock something down, or to lower or reduce something in size or force. The noun is a later, more abstract development. Its meaning followed the verb from literal lowering toward the lessening of a burden, a debt, or the intensity of a problem. The Middle English form "abatere," which the source records as the immediate ancestor, shows the word already being used as an agent noun in that period, so the suffix is not a modern addition. The core idea has stayed constant: something that pushes a force downward until it weakens.
