Did you know?

We’d hate to be extra, so we won’t weigh you down with a lot of extraneous information about the word extraneous. Instead, we’ll tell you that it has been a part of the English language since at least the mid-1600s, and that it comes from the Latin word extrāneus, which means “not belonging to one’s family or household; external.” Extrāneus—a combination of the Latin adverb/preposition extrā  (“outside” or “beyond”) and adjective suffix -āneus—is also the root of the English words strange and estrange; its influence is even more obvious in the Spanish adjective extraño, meaning “strange.” The “outside/beyond” senses of extrā are also evident in non-extraneous English words like extraterrestrial, which refers to a creature originating from “outside” planet Earth, and extrajudicial, which describes something “beyond” what is allowed by a court.
