Etymology: The word "totalizer" is a straightforward formation: "totalize" plus the agent suffix "-er," meaning a device or person that totals things. "Totalize" itself comes from "total," which traces back to Latin "totus" meaning "whole" or "entire," and the verb-forming ending "-ize" arrived through Late Latin "-izare" and Greek "-izein," which turned nouns and adjectives into verbs meaning "to make into" or "to treat as." The "-er" ending is the familiar English agent suffix, inherited from Old English "-ere," which was itself borrowed from Latin "-arius" through Proto-Germanic. It is the same ending found in "baker" or "teacher." In practice, a totalizer is a machine that adds up figures as they arrive, most famously the mechanical counters used in betting systems and sporting scoreboards, where it keeps a running sum of wagers or points.
