Did you know?

Rancid and putrid and fetid—oh my! All three words are used to describe unpleasant smells and tastes, and each traces its roots to a "stinky" Latin word: rancid can be traced back to rancēre; the root of putrid shares an ancestor with putēre; and fetid comes from foetēre—all verbs meaning "to stink." Not long after entering the language in the early 17th century, rancid also developed a second, figurative sense which is used for non-gustatory and non-olfactory offenses, as in "rancid hypocrisy."
