Examples:

"... this morning when I was going out to play in the gardens, I went to put on my favorite baseball cap since the sun was hot and, being bereft of my own natural covering, I wished to avoid a sun-scorched scalp." — Dick Brooks, The Daily Gazette (Schenectady, New York), 7 May 2026





Did you know?

In Old English, the verb berēafian meant "to deprive of something." The modern equivalent (and descendant) of berēafian is bereave, a verb used to say that one has deprived or stripped someone of something, often suddenly and unexpectedly, and sometimes by force. Bereft comes from the past participle of bereave; Shakespeare uses the participle in The Merchant of Venice, when Bassanio tells Portia, "Madam, you have bereft me of all words." But by Shakespeare's day bereft was also being used as an adjective. The Bard uses it in The Taming of the Shrew, as a newly obedient and docile Katharina declares, "A woman mov'd is like a fountain troubled—muddy, … thick, bereft of beauty."

Examples:

"This recipe uses a classic marble cake technique to swirl rich layers of cinnamon into a fluffy olive oil-scented loaf cake.

Did you know?

Japanese scientist Kikunae Ikeda is credited with identifying as a distinct taste the savory flavor of the amino acid glutamic acid, which he first noticed in soup stocks made with seaweed. This fifth basic taste—alongside sweet, sour, salty, and bitter—was named umami, meaning "savoriness" in Japanese. Umami can be experienced in foods such as mushrooms, anchovies, and mature cheeses, as well as in foods enhanced with monosodium glutamate, or MSG, a sodium salt derived from glutamic acid.

Merriam-Webster's Word of the Day for June 28, 2026 is:





gainsay • \gayn-SAY\ • verb

Examples:

“Whatever you think of it, there’s no gainsaying the fact that ‘The Sound of Music’ is a remarkably durable vehicle. It’s frequently produced, and suffered no lasting damage to its reputation from a live NBC performance in 2013 ...” — Don Aucoin, The Boston Globe, 9 Jan. 2026





Did you know?

You might have trouble figuring out the meaning of gainsay if you’re thinking of our modern word gain plus 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.”

Merriam-Webster's Word of the Day for June 27, 2026 is:





oracular • \aw-RAK-yuh-ler\ • adjective

Oracular is a formal word that can describe something used to forecast or prophesize, or something that resembles or relates to something used for such purposes. Oracular can also describe something that resembles an oracle—a person (such as a priestess of ancient Greece) through whom a deity is believed to speak; in this sense, an oracular statement, voice, etc. conveys wisdom or solemnity.

// A few recordings of the famous speaker still exist, and though his language is formal to the point of sounding almost foreign to the modern listener, the oracular quality of his speech remains effective.

Examples:

"The conversation that unfolds is some of [writer Ben] Lerner's most brilliant and daring writing to date, a mad, oracular burst of speech—about technology, parenthood, and dreaming—that flits effortlessly between prose and poetry." — Kevin Lozano, Vulture, 3 Apr. 2026





Did you know?

When the ancient Greeks had questions or problems, they would turn to the gods for answers by consulting an oracle, a person through whom the gods communicated, usually in the form of cryptic verse. Oracle also referred to the god's answer or to the shrine that worshippers approached when seeking advice; the word's root is the Latin verb orare, which means "to speak." English speakers today can use oracle to simply refer to an authoritative pronouncement or to a person who makes such pronouncements—for example, "a designer who is an oracle of fashion." And the related adjective oracular is used in similar contexts: "a designer who is an oracular voice of fashion."

Examples:

“In the old days, which weren’t that long ago ... there was that ritual moment when a rock ‘n’ roll idol, in the midst of delivering a classic anthem, would point the mic away from himself and into the arena, indicating that it was time for the audience to take over and sing the lines. It might be Springsteen doing ‘Thunder Road,’ or Madonna doing ‘Holiday.’ ... The loving symbiosis of pop star and pop audience doesn’t get much more reverent than that.” — Owen Gleiberman, Variety, 7 May 2026





Did you know?

Symbiosis was adopted by the scientific community in the late 1800s, coming ultimately (via German) from the Greek symbíōsis, meaning “living together, companionship.” Of course, there are a lot of ways to live together and, accordingly, several flavors of symbiosis. When a biological symbiosis between two organisms is mutually beneficial, it is termed mutualism. For example, oxpeckers are birds so named because they “peck” ticks off of infested cattle and wild mammals, a likely satisfying arrangement for both parties, and textbook mutualism. When one organism lives off another at the other’s expense, however (as, for one icky instance, head lice do), it’s called parasitism. If only parents of elementary school students could call upon an equivalent of oxpeckers to engage in mutualistic symbiosis when the need arose, but alas.
