Examples:

“At home, your demeanor impacts your family more than you realize. Your kids feed off your energy. If you’re engaged, positive, and present, they feel it.” — Brandon Brigman, The Rockdale Citizen (Conyers, Georgia), 30 Mar. 2026





Did you know?

The history of demeanor begins with a threat: the word has its roots in Latin minārī, meaning “to threaten.” A form of that word was used in contexts having to do with driving animals—that is, impelling them to move—and from this word came more recent French ancestors having to do with leading, guiding, and behaving. By the 14th century, English had adopted a word out of this lineage: the verb demean meaning “to conduct or behave (oneself) usually in a proper manner.” (Another demean, defined as “to lower in character, status, or reputation,” entered the language later by way of the mean that has to do with being cruel.) The noun demeanor was formed in the following century through the addition of the suffix -or.

Examples:

“He [Bob Dylan] never expressed embarrassment over the dismal commercial failure of his would-be cinematic masterpiece, Renaldo and Clara, even after the film’s financers, Warner Bros., warned Dylan that the film’s nearly five hour running time would ensure its failure (which would prove true). Dylan insisted that the film needed every frame. And who knows, art history may vindicate him.” — Ron Rosenbaum, Bob Dylan: Things Have Changed, 2025





Did you know?

It’s hard not to marvel at the rich history of vindicate. Vindicate, which has been used in English since at least the mid-16th century, comes from a form of the Latin verb vindicare, meaning “to set free, avenge, or lay claim to.” Vindicare, in turn, comes from vindex, a noun meaning “claimant” or “avenger.” Truly, vindex has proven to be an incredible hulk of a word progenitor over the centuries. Other descendants of this “avenger” assembled in English include avenge itself, revenge, vengeance, vendetta, and vindictive.

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

Examples:

“Ray Naranjo is a Native American chef from Santa Clara Pueblo in northern New Mexico. He’s a big, affable man with a wide, warm smile, built more for a football field than his food truck, Manko.” — Michael Shaikh, The Last Sweet Bite: Stories and Recipes of Culinary Heritage Lost and Found, 2025





Did you know?

There is nothing in the meaning of affable (“friendly and easy to talk to”), nor in its etymology (the word traces back to the Latin verb affārī, meaning “to speak to, address”), to suggest it is more properly applied to men than to women, but English-speaking people behave as though it is. This was not always true; in the 16th through the 19th centuries, it was not uncommon to see the word describing women, but no more. We once surveyed all the cases in which a single newspaper used affable over a 12-month period. The word occurred in 102 articles, and in 4 occurrences it described women, while in 85 occurrences it described men (in the other cases affable was used to describe a conga line, email, musical compositions by Robert Ward, cats in general, and one male dog). None of this need affect your use of the term. You should feel free to apply it in whatever way seems suitable. Think of this more as a reminder that the currents of our language are deep and occasionally mysterious, gently nudging us along paths we don’t even see.

kiki • \KEE-kee\ • noun

Examples:

“The year 2024 will long be remembered in pop culture as the year of #bratsummer, christened, of course, by the early-June release of an instantly-iconic pop album, Charli XCX’s Brat. It was the cultural equivalent of the hippies’ summer of love in 1967, but for the girls and gays a singular moment in time when every day offered the chance of a kiki and every night flirted with throwing a rave.” — Vanessa Quilantan, The Dallas Observer, 26 Aug. 2025





Did you know?

Let’s chitchat about the word kiki, a fun word for a fun, gossipy gathering. While its exact origins are unclear, we know that kiki has roots in the ballroom community, a primarily Black and Latino drag subculture that spread in US cities especially in the 1980s–90s. In the early 2000s, a movement emerged within ball culture that was often referred to as the kiki scene. This involved support groups and social services for LGBTQ+ youth, and provided opportunities to socialize, including in the form of so-called kiki balls, or festive, party-like drag performances. This scene was notably captured in the 2016 documentary Kiki, popularly considered a sequel to 1990’s Paris is Burning. Kiki is also used as a verb meaning “to share lively gossip or frank conversation”—in other words, “to have a kiki.”

Merriam-Webster's Word of the Day for May 15, 2026 is:





tortuous • \TOR-chuh-wus\ • adjective

Tortuous describes something that has many literal or figurative twists and turns.

// The tortuous mountain path rewards climbers with a stunning view of the town below.

// Getting approval for a project of this magnitude is a tortuous process.

Examples:

“Christopher Nolan’s latest epic is an adaptation of the ancient Greek epic poem, The Odyssey. ... Homer’s poem is centered on Greek hero King Odysseus ... and his tortuous, 10-year journey home to Ithaca after the Trojan War.” — Lexy Perez, The Hollywood Reporter, 4 Jan. 2026





Did you know?

Be careful not to confuse tortuous with torturous. These two words are relatives—both ultimately come from the Latin verb torquēre, which means “to twist,” “to wind,” or “to wrench”—but tortuous means “winding” or “crooked,” whereas torturous means “painfully unpleasant.” (Its oldest meaning is “causing torture.”) Something tortuous, such as a twisting mountain road, might also be torturous (if, for example, you have to ride up that road on a bicycle), but that doesn’t make these words synonyms. The twists and turns that mark a tortuous thing can be literal (“a tortuous path” or “a tortuous river”) or figurative (“a tortuous argument” or “a tortuous explanation”), but you should veer away from using the term if no implication of winding or crookedness is present.
