Etymology: "Uncaused" is about as plain as English etymology gets: the prefix "un-" attached to "caused," meaning "without any cause." The prefix descends through Old English "un-" from a Proto-Germanic form, and it carries the same negating force it has in words like "unhappy" or "unknown." The Proto-Indo-European root behind that prefix, *ne, is the ancestor of the negative in many languages, which is why the same sound turns up across so much of Europe and beyond. "Caused" is the past participle of "cause," so "uncaused" literally means "not caused." Because the parts are transparent, the word needs no special story: anyone who knows what "cause" and "un-" mean already knows what "uncaused" means. Its usefulness lies mostly in philosophy and theology, where people talk about a first cause that itself has no cause.
