Did You Know?

It’s easier to give credit to people who adhere to their creed than to give credence to what miscreants say, or for that matter, to find recreants altogether credible. That sentence contains a half dozen words which, like today’s credulous, are descendants of credere, the Latin verb that means "to believe" or "to trust": credit ("honor," as well as "belief"); creed ("guiding principle"); credence ("acceptance as true"); miscreant ("a heretic" or a criminal); recreant ("coward, deserter"); and credible ("offering reasonable grounds for being believed"). Credulous is even more closely allied to the nouns credulity and credulousness (both meaning "gullibility"), and of course its antonym, incredulous ("skeptical," also "improbable").
