Did You Know?
"Licit" is far less common than its antonym "illicit," but you probably won’t be surprised to learn that the former is the older of the two. Not by much, though: the first known use of "licit" in print is from 1483, whereas "illicit" shows up in print for the first time in 1506. For some reason "illicit" took off while "licit" just plodded along. When "licit" appears these days it often modifies "drugs" or "crops." Meanwhile, "illicit" shows up before words like "thrill" and "passion" (as well as "gambling," "relationship," "activities," and, of course, "drugs" and "crops.") The Latin word "licitus," meaning "lawful," is the root of the pair; "licitus" itself is from "licēre," meaning "to be permitted."
