Etymology: "Subworlds" is the plural of "subworld," a compound formed from the prefix "sub-" (from Latin "sub," meaning "under" or "below") and "world." The pattern is a transparent one: a subworld is a world beneath or within a larger one, so the word needs little explanation beyond its parts. Its meaning, a distinct realm or dimension within a larger universe, follows directly from that literal sense of a world set inside another. The plural form simply counts several such realms at once, which is why the word is most often heard in discussions of fiction, where a single universe may contain many separate settings with their own inhabitants and stories. Because both elements are ordinary English words, the term is built entirely from familiar material rather than from any specialised technical vocabulary.
