Did You Know?
You may be familiar with the more commonly used "bona fide" (boh-nuh-FYE-dee), which can mean "made in good faith" (as in "a bona fide agreement") or "genuine or real" ("a bona fide miracle"). You also may have encountered the noun "bona fides," used in reference to evidence of a person's good faith, genuineness, qualifications, or achievements. Not surprisingly, in Latin "bona fide" means "in good faith" and "mala fide" means "in bad faith." These days "mala fide," which dates from the mid-16th century, tends to turn up primarily in legal contexts.
