Etymology: "Expender" is a simple formation: the verb "expend" with the agent suffix "-er," so it names a person (or sometimes a thing) that expends. "Expend" itself comes from Latin "expendere," meaning to weigh out, pay out or spend, built from "ex-" (out) and "pendere" (to weigh or hang). That original sense of weighing out payment is still visible in the modern word: the one who expends is the one who pays out.
