sagacious

Merriam-Webster's Word of the Day for July 2, 2026 is: sagacious • \suh-GAY-shus\  • adjective Someone or something described as sagacious has or shows an ability to understand difficult ideas and situations and to make good decisions. Sagacious may be considered a formal synonym of wise [https://www.merriam-webster.com/dictionary/wise] and discerning [https://www.merriam-webster.com/dictionary/discerning]. // Student reviews paint the writing professor as a sagacious mentor and a compassionate teacher. See the entry > [https://www.merriam-webster.com/dictionary/sagacious] Examples: “It’s a lyrical truism with the kind of wisdom that feels particularly sagacious only within the context of pop music: Of course breaking up is hard to do, but when expressed by [Neil] Sedaka at the end of each verse (and the beginning of each bridge) of his pained plea to his partner to ‘give our love another try,’ it feels like hard-earned insight.” — Andrew Unterberger, Billboard, 2 Mar. 2026 Did you know? You might expect, wise word wonk that you are, that the word sagacious is etymologically linked with sage [https://www.merriam-webster.com/dictionary/sage], which, as an adjective, means “wise [https://www.merriam-webster.com/dictionary/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.

Nabob, as it later came to be spelled, gained its extended sense of “a prominent person” in the 18th century, when it was applied sarcastically to British officials of the East India Company [https://www.britannica.com/topic/East-India-Company] returning home after amassing great wealth in Asia.

You might have trouble figuring out the meaning of gainsay if you’re thinking of our modern word gain [https://www.merriam-webster.com/dictionary/gain] plus say [https://www.merriam-webster.com/dictionary/say]. It should help to know that the gain part comes to us from the Old English word gēan-, meaning “against” or “in opposition to.” (The familiar verb gain comes from Anglo-French and is unrelated.) In Middle English, gēan- was joined to seyen (“to say”) to form gein-seyen, which led to the modern word gainsay. So when you see gainsay, think “to say against”—that is, “to deny” or “to contradict.”
