You might expect, wise word wonk that you are, that the word sagacious is etymologically linked with sage, which, as an adjective, means “wise” or, as a noun, “a wise person.” However, despite similarities of spelling, sound, and sense, the two words are not closely related. Sagacious comes from sagire, a Latin verb meaning “to perceive keenly,” while sage comes from a different Latin verb, sapere, which means “to taste,” “to have good taste,” or “to be wise.” Sagacious entered the English language around the beginning of the 17th century and, for some decades, referred to perceptiveness of sight, taste, and especially, smell, hewing close to its Latin ancestor. It has largely lost the sense (no pun intended) of sensory keenness, and now almost exclusively describes someone or something displaying keen, discerning judgment.
