Did you know?

Rancid has a fairly straightforward history; it derives from Latin rancidus, itself from the Latin verb rancēre, meaning "to be rancid" or "to stink." In addition to the related words rancidness and rancidity, another descendant of rancēre in English is rancor, meaning "bitter deep-seated ill will." (Rancor passed through Middle French rather than being borrowed into English directly.) These days, rancid also has developed a second, extended sense which is used in the context of offenses to less literal or physical senses than those of smell or taste, and you might see references to "rancid behavior" or "a rancid personality."
