Etymology: "Rocketries" is simply the plural of "rocketry," and the plural matters less than the word's path into English. "Rocketry" is formed from "rocket" plus the suffix "-ry," which came into English from Old French "-erie" and ultimately traces back through Latin and Italian to the word "rocchetto," a small spindle or bobbin. The Italian "rocchetta" referred to a distaff-like spindle, and English borrowed it as "rocket," originally naming a kind of projectile or firework before the word broadened to cover missiles and space vehicles. The suffix "-ry" does most of the work in "rocketry," turning a concrete object into a word for an activity, a craft, or a body of knowledge. English already had many such formations, such as "pottery" and "machinery," and "rocketry" follows the same pattern, naming the whole field rather than any single device. The plural "rocketries" is a formal, countable form, used when referring to distinct practices or branches of the discipline.
