Did You Know?
You might expect the root of "sagacious" to be "sage," which means "wise" or "wise man," but that wouldn't be a wise assumption. Despite their similarities, the two words are not all that closely related. "Sagacious" traces back to "sagire," a Latin verb meaning "to perceive keenly." It’s also related to the Latin adjective "sagus" ("prophetic"), which is the ancestor of our verb "seek." Etymologists believe that "sage" comes from a different Latin verb, "sapere," which means "to taste," "to have good taste," or "to be wise."
