Obdurate is a formal word that means "resistant to persuasion." It is usually used to describe someone who is not willing to change their methods or opinions, or something that is not easily altered.

Examples:

"... even great careers must end sometime, and as often as not against obdurate wills." — Greg Baum, The Sydney Morning Herald, 17 Dec. 2025





Did you know?

When trying to persuade someone who has an obdurate disposition, you may end up feeling rather dour about your ability to change their mind. To endure such encounters in the future, you may find that you need to be more durable and not let the person's mulishness get you down. Maybe you will find such situations less stressful if you can face them knowing that the words obdurate, dour, endure, and durable are etymological kissing cousins. All trace back to the Latin adjective durus, which means "hard."

Merriam-Webster's Word of the Day for July 16, 2026 is:





bibelot • \BEE-buh-loh\ • noun

A bibelot is a small household ornament or decorative object.

// His grandfather set up a table every week at the flea market where he sold all sorts of bibelots and bric-a-brac, from ceramic figurines to tiny blown glass sculptures.

Examples:

“One by one, the beads and baubles and charms and bibelots have been cleaned and polished and now they are being placed on shelves, in jars and containers, in bins, and in a bathtub in Beadniks’ new store on Main Street.” — Bob Audette, The Brattleboro (Vermont) Reformer, 21 June 2025





Did you know?

The English language, it would seem, can’t get enough of synonyms for trinket, including gewgaw, gimcrack, and knickknack, just as lovers of tchotchkes can’t get enough of such ornamental trifles. Lady Charlotte Guest (1812-1895) was just such a lover of baubles and bric-a-brac. Not only was Guest an accomplished linguist, educator, publisher, and philanthropist, she also amassed collections of everything from porcelain to playing cards, which she ultimately donated to museums. We also have Guest to thank for the first known use in English of the French word for “trinket,” bibelot, which she recorded in a journal entry in 1873 while in Paris: “After 3, walked up to Lady Hopetoun’s to amuse her with some of our little bibelots.”

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





loquacious • \loh-KWAY-shus\ • adjective

Loquacious means “liking to talk and talking smoothly and easily.” Someone described as loquacious might also be called wordy (prone to using more words than necessary) or garrulous (tending to talk a lot).

// We were entertained all afternoon by our host’s loquacious parrot and its nonstop script of favored phrases.

Examples:

“Due to their loquacious nature, marmosets have recently become a focus of studies on the evolutionary origin of human speech and language.” — Tobias Kahland et al., Nature Communications, 28 Mar. 2026





Did you know?

Loquacious undeniably has a poetic ring to it. It’s been a favorite of the writerly sort since it made its first appearance in English in the 17th century and, with poetic license, writers stretched its meaning beyond “talkative,” and especially “excessively talkative,” to describe such things as the chattering of birds and the babbling of brooks. The ultimate source of all this chattiness is loquī, a Latin verb meaning “to talk, speak.” Other words descended from loquī include colloquial, eloquent, soliloquy, and ventriloquism.

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





yaw • \YAW\ • verb

The verb yaw when used for the action of a ship, aircraft, spacecraft, or projectile means "to move to the left or right especially in an uncontrolled manner." More broadly, yaw is used as a synonym of alternate to mean "to change from one to another repeatedly."

// The rogue wave hit the vessel, and the ship yawed hard to the right.

// The album yaws from soulful ballad to up-tempo pop hit and back again.

Examples:

"The out-of-control motion radiated down to the spacecraft itself, which began yawing and pitching in response to the force." — Jeffrey Kluger, Time, 11 Nov. 2025





Did you know?

In the heyday of large sailing ships, numerous nautical words appeared on the horizon. Yaw is one such word. Its origin isn't exactly known, but it began turning up in print in the 16th century, first as a noun meaning "movement off course" or "side to side movement," and then as a verb. For centuries, it remained a sailing word—often alongside pitch ("to have the front end rise and fall")—with occasional extended use as a synonym of the verb alternate. When the era of airplane flight dawned, much of the vocabulary of sailing found new life in aeronautics, and "yawing" was no longer confined to the sea. Nowadays yaw, pitch, and roll are just as likely to be used by pilots and rocket scientists to describe the motion of their crafts.

Merriam-Webster's Word of the Day for July 13, 2026 is:





implacable • \im-PLAK-uh-bul\ • adjective

Someone or something described as implacable is not capable of being appeased or changed.

// The project faced implacable resistance from community members, and is now off the table.

Examples:

“Unlike, say, the globetrotting stories of Ian Fleming or John le Carré, in which victories only temporarily frustrate an implacable foe, [Agatha] Christie’s smaller worlds feel put right when the cover closes or credits roll.” — The Economist, 17 Jan. 2026





Did you know?

Implacable is rooted in the Latin verb placare, meaning “to soothe,” but its im- prefix is a variant of the negating prefix in- (as in inactive) and it signals that there’s nothing warm and fuzzy here. Someone or something described as implacable cannot be soothed, which usually means trouble: implacable is most often attached to words like foe, enemy, hatred and hostility. The opposite of implacable is, of course, placable; it means “easily soothed,” but sadly isn’t called upon very often. Another placare word is likely more familiar. Placate means “to soothe or appease”; it’s frequently applied when an angry person is made to feel less so.
