Did you know?

Evolve? Check. Revolve? Check. Devolve? Now we’re on a roll—literally. All three of these words (and more) evolved from the Latin verb volvere, meaning “to set in a circular course, to cause to roll, to bring round.” The Latin ēvolvere means “to roll out or away”; revolvere means “to roll back to a starting point”; and dēvolvere means “to roll (something) down.” In its earliest uses in the 15th century, devolve literally meant “to roll onward or downward.” Today the word is typically used for a more figurative rolling down, as when an organization devolves power—that is, passes power down—to those at a lower level of authority, or when a deteriorating situation is described as “devolving into chaos.” One word, multiple uses. That’s just how English rolls.

Merriam-Webster's Word of the Day for August 25, 2026 is:





tilde • \TIL-duh\ • noun

Tilde refers to the mark ~ placed especially over the letter n (as in the Spanish señor, meaning "sir") to denote the sound \nʸ\, or over vowels (as in the Portuguese irmã, meaning "sister") to indicate nasality. When a tilde appears as an independent character, it usually means "approximately" (as in "we'll be there in ~ 30 minutes").

// A familiar example of the tilde appears in the name of the Brazilian city São Paulo.

Examples:

"Californians with accents, tildes and other diacritical marks in their names will soon be able to have their vital records accurately reflect their names." — Linh Tat, Orange County (California) Register, 30 Dec. 2025





Did you know?

The terms piña colada and La Niña share more than just a "cool" factor: both are Spanish loan words whose spellings include tildes, those wavy marks which in these examples are placed over the letter n to indicate a blend of the sounds of n and y. Tilde is itself a Spanish borrowing rooted in the Latin titulus, an ancestor of the English words title and titular that means "title" or "inscription." The Spanish and English applications of tilde are distinct. In Spanish, tilde refers most commonly to the accent symbol, while ñ is its own member of the alphabet (pronounced "EN-yay"). In contrast, English speakers use tilde specifically for the aforementioned mark. In addition to functioning as a diacritic—that is, a mark paired with a character to indicate pronunciation—the tilde may be used as an independent character to indicate approximation, negation in logic, or similarity in mathematics.

Merriam-Webster's Word of the Day for August 24, 2026 is:





expeditious • \ek-spuh-DISH-us\ • adjective

Expeditious is a formal word that is used to describe someone acting in a quick and efficient way, or something done in such a manner.

// Both sides hoped for an expeditious resolution of the dispute.

See the entry >





Examples:

“Inspectors were on campus Friday afternoon with a certified arborist to determine which trees are protected and the extent to which any damage or removals have occurred, according to the city. ‘The City is prepared to conduct this inspection work in an expeditious manner and supports the goal of returning students to a safe campus as soon as possible,’ the city’s statement said.” — Ryan Carter, The Los Angeles Daily News, 10 July 2026





Did you know?

Expeditious has had quite the journey through the English language. It comes to us from the related noun expedition, which in turn comes from the Latin verb expedire (“to set free” or “to make ready”). When expedition first set forth in English in the 1400s, it did so with two meanings that are still in use today, “a journey especially by a group of people for a specific purpose” and “efficient promptness.” Expeditious followed as an adjectival form of the latter. Something (such as, say, preparation for a long voyage) done expeditiously is done quickly and efficiently; in other words, it is expedited. Like expeditious and expedition, expedite too comes from expedire.

Merriam-Webster's Word of the Day for August 23, 2026 is:

Examples:

“On another Friday ... I led a nature writing workshop at the library’s Fowler branch. ... I had everyone draw a map of a place they loved and populate their maps with landmarks. Then we all went around and shared our drawings. Inevitably (after first acknowledging our lack of artistic prowess) stories emerged. Walks with long-gone, beloved dogs. Times someone had been caught out in bad weather.” — Steve Edwards, Literary Hub, 4 Dec. 2025





Did you know?

Prowess is a word with a lot to be proud of. Not only has it performed gallantly for the English language since the 13th century, but it has stayed relatively stalwart in hewing to its original meaning, which is quite an accomplishment. When prowess first joined the ranks of the lexicon, it could be used to refer to bravery, skill, and valor—especially those virtues as encountered in military contexts—or to individual acts of derring-do. The latter was usually used in the plural, as when people waxed rhapsodic about the “prowesses” of knights or some such. Today’s “extraordinary ability” meaning, which developed in the 17th century, tends to stick to the singular form, as when it’s used to describe those with intellectual prowess, or to someone known for their prowess as a fundraiser.
