The story

Picture a Roman mathematician piling one quantity on top of another and labeling the result multiplus: “many-fold.” That compact Latin construction eventually traveled through French multiple before appearing in English in the 1640s. The first half, multi-, is a prolific little engine meaning “many”—the same family that gives us multitude, multilingual, and multifarious. The second half, -plus, is the “fold” or “more” part, a distant linguistic cousin of the plus sign that now sits on every calculator. English later put the word to work in arithmetic, in “multiple choice” by 1915, and even in “multiple exposure” photography, where one film frame receives several visual impressions—many images folded into one.
