Etymology: "Devoter" is a plain English formation: the verb "devote" with the agent suffix "-er" added, producing a noun for one who devotes. The verb itself comes from Latin "devovere," meaning to vow or dedicate solemnly, built from "de-" (away, down) and "vovere" (to vow). Its early sense was closer to a sacred pledge, which is why the verb still carries a whiff of solemn commitment. The noun, by contrast, is a straightforward combination of an existing English verb and a common suffix, so it shows no dramatic shift in meaning. What it describes is someone who gives their energy or loyalty wholeheartedly to a cause, pursuit or belief, a sense that grows naturally out of the verb's idea of dedication.
