The totalizator displayed the total amount of bets placed on the horse race.
Totalizator → It is formed from "total" (from Latin "totalis", meaning whole or complete) and "-ator" (a suffix used to indicate an agent or something that performs an action). The word "totalizator" refers to a device or system that totals or sums up results, particularly in betting contexts.
Think of something that makes a 'whole' ('total') by 'performing' an action ('-ator') — that's why a totalizator sums up results.
