Etymology: "Decaliter" is a straightforward metric coinage: the prefix "deca-" joined to "liter," with the "liter" half itself a French unit name borrowed into English. The prefix goes back to Ancient Greek "dékas," meaning a group of ten, from "dékă," ten. That Greek root travelled through Late Latin "decas" and reached modern European languages in forms like French "déca-", which the metric system adopted as a prefix meaning ten times the base unit. Because the metric system was built deliberately in revolutionary France, its prefixes were chosen on purpose rather than evolving over centuries. "Deca-" stands in a series with "hecto-" (hundred) and "kilo-" (thousand), all drawn from Greek number words. The word itself is therefore a modern scientific formation rather than an ancient term: the Greeks had "dekas" for a set of ten, but nobody in antiquity measured volume in decaliters.
