Etymology: Its deepest root is a warning. Latin "monere" meant "to warn," and from it came "monstrum," an omen or portent, which is also the ancestor of English "monster." Latin "monstrare" meant "to show," and adding "de-" produced "demonstrare," to point out or prove clearly. Showing something outright was the original sense, not a later extension. English built the rest in stages. "Demonstrable" describes something that can be shown or proved. The prefix "in-" reverses it to mean "not able to be shown," and the suffix "-ity," which came into English through French from Latin "-itas," turns the adjective into a noun for a state or quality. The result literally names the condition of being impossible to prove or point out.
