Larry's Pretty Good Word of the Day

Merriam-Webster's Word of the Day for April 18, 2026 is:

hiatus • \hye-AY-tus\  • noun

In general contexts, hiatus usually refers to a period of time when something, such as an activity or program, is suspended. In biology, hiatus describes a gap or passage in an anatomical part or organ, and in linguistics, it refers to the occurrence of two vowel sounds without pause or intervening consonantal sound.

// The actor, who’s been on hiatus for several years, will be starring in a new film.

Examples:

“Following its return in 2025 after a nearly three-year hiatus, the 52nd American Music Awards are heading back to Las Vegas to be broadcast live from a new venue, the MGM Grand Garden Arena.” — Steven J. Horowitz, Variety, 10 Mar. 2026

Did you know?

This brief hiatus in your day is brought to you by, well, hiatus. While the word now most often refers to a temporary pause, hiatus originally referred to a physical opening in something, such as the mouth of a cave, or, as the 18th century British novelist Laurence Sterne would have it, a sartorial gap: in the wildly experimental novel Tristram Shandy, Sterne wrote of “the hiatus in Phutatorius’s breeches.” Hiatus comes from the Latin verb hiare, meaning “to yawn,” which makes it a distant relation of both yawn and chasm. And that’s all we have for now—you may resume your regular activities.

Merriam-Webster's Word of the Day for April 17, 2026 is:

postulate • \PAHSS-chuh-layt\  • verb

Postulate is a formal word used to mean “to suggest something, such as an idea or theory, especially in order to start or continue a discussion.”

// Scientists have postulated the existence of water on the planet’s largest moon.

Examples:

“Based on their findings, researchers postulate that Homo sapiens reacted better to lead exposure evolutionarily than Neanderthals, a species that were close relatives to Homo sapiens and that went extinct around 40,000 years ago.” — Mason Leath, ABC News, 16 Oct. 2025

Did you know?

When you postulate an idea or theory you suggest that it is true especially for the purposes of an argument or discussion. The word postulate is mostly at home in formal and academic contexts, but don’t let that stop you from postulating, for example, that takeout for dinner makes sense given the cook’s delayed return home from work, or that a thunderstorm is imminent given the cumulonimbus building on the horizon. This “hypothesize” sense of postulate emerged in the early 18th century, but the verb first appeared in English centuries earlier in ecclesiastical contexts, as recorded in our Unabridged dictionary. To postulate someone, according to this sense of the word, was to request that a higher authority in the church sanction their promotion even though they would otherwise be disqualified by church rules or regulations.

Merriam-Webster's Word of the Day for April 14, 2026 is:

enjoin • \in-JOIN\  • verb

Enjoining is about requiring or prohibiting. To enjoin a person is to direct or order them to do something. To enjoin an act or practice is to prohibit it; in legal contexts, that prohibition is by way of a judicial order.

// Our guide enjoined us to take great care as we began our journey.

// The court has enjoined the ban.

// We were enjoined from speaking on the tour.

Examples:

“Attorney General Brian Schwalb filed a lawsuit Thursday ... to put a landlord accused of providing unsuitable living conditions to his renters out of business. ... The lawsuit seeks restitution for impacted tenants and to ‘enjoin the defendants from doing business in the District.’” — Gary Fields, The Associated Press, 13 Feb. 2026

Did you know?

Enjoin has the Latin verb jungere, meaning “to join,” at its root, but the kind of joining expressed by enjoin is quite particular: it is about linking someone to an action or activity by either requiring or prohibiting it. When it’s the former at hand—that is, when enjoin is used to mean “to direct or order someone to do something”—the preposition to is typically employed, as in “they enjoined us to secrecy.” When prohibition is involved, from is common, as in “attendees were enjoined from photographing the event.” In legal contexts, enjoining involves prohibition by judicial order, through means of an injunction, as in “the judge enjoined the sale of the property.”

Merriam-Webster's Word of the Day for April 12, 2026 is:

recondite • \REK-un-dyte\  • adjective

Recondite is a formal word used to describe something that is difficult to understand or that is not known by many people.

// The text addresses a technical subject using recondite vocabulary, which makes it very difficult to read.

// The candy has the perfect balance of sweet and tart, but what delights me most are the recondite facts printed inside the wrapper.

Examples:

“Each medical school has variations in its prerequisites, but all require a strong foundation in the sciences. This includes courses such as the notoriously recondite organic chemistry as well as biology, general chemistry, and physics.” — Richard Menger, Forbes, 18 Aug. 2025

Did you know?

Recondite is one of those underused but useful words that’s always a boon to one’s vocabulary. Though it describes something difficult to understand, there is nothing recondite about the word’s history. It dates to the early 1600s, when it was coined from the Latin word reconditus, the past participle of recondere, “to conceal.” (“Concealed” is also a meaning of recondite, albeit an obscure one today.) Remove the re- of recondite and you get something even more obscure: condite, an obsolete verb meaning both “to pickle or preserve” and “to embalm.” Add the prefix in- to that quirky charmer and we get incondite, which means “badly put together,” as in “incondite prose.” All three words have the Latin word condere at their root; that verb is translated variously as “to put or bring together” and “to put up or store”—as in, perhaps, some pickles or preserves.

Merriam-Webster's Word of the Day for April 10, 2026 is:

glaucous • \GLAW-kus\  • adjective

Glaucous as a color word can describe things of two rather different shades: a light bluish-gray or bluish-white color, or a pale yellow-green. It can also mean "having a powdery or waxy coating that gives a frosted appearance and tends to rub off."

// His glaucous eyes grew wide with curiosity.

// The tree's glaucous leaves help prevent sun damage.

Examples:

"... an enchanting Mediterranean-inspired planting scheme of soft pinks, silver greys, and glaucous foliage ... evoke[s] calm and relaxation." — Joy Baker, Bedford (England) Today, 20 Feb. 2026

Did you know?

Glaucous came to English—by way of the Latin adjective glaucus—from the Greek glaukos, meaning "gleaming" or "gray." It has been used to describe a range of pale colors from a yellow-green to a bluish-gray. The word is often found in horticultural writing describing the pale color of the leaves of various plants as well as the powdery bloom that can be found on some fruits and leaves. Birders may also recognize the word from the names of several birds, including the glaucous gull and glaucous-winged gull so named for their partially gray plumage. The stem glauc- appears in some other English words, the most familiar of which is glaucoma, referring to a disease of the eye that can result in gradual loss of vision. Glauc- also appears in the not-so-familiar glaucope, a word used to describe someone with fair hair and blue eyes; glaucope is a companion to cyanope, the term for someone with fair hair and brown eyes.
