Magic words are phrases used in fantasy fiction or by stage magicians. Frequently such words are presented as being part of a divine, adamic, or other secret or empowered language. Certain comic book heroes use magic words to activate their powers. Magic words are also used as Easter eggs or cheats in computer games, other software, and operating systems. (For example, the words xyzzy, plugh, and plover were magic words in the classic computer adventure game Colossal Cave Adventure.)
