Merriam-Webster's Word of the Day

Merriam-Webster's Word of the Day for December 31, 2025 is: retrospective • \reh-truh-SPEK-tiv\ • adjective Retrospective describes something that relates to the past or to something that happened in the past. // The museum has curated a retrospective exhibit of the artist's early works. See the entry > Examples: "Our retrospective sense of time hinges on memory: Periods rich in novel, significant experiences feel longer, while routine collapses duration ..." — Marc Wittmann, Psychology Today, 16 Nov. 2025 Did you know? At the year's end, both introspection and retrospection are common. While introspection involves looking inward and taking stock of oneself, retrospection is all about recollecting and contemplating things that happened in the past. A look back at the history of the related adjective retrospective reveals that it retains a strong connection to its past: its Latin source is retrospicere, meaning "to look back at." Retrospective can also be used as a noun referring to an exhibition that "looks back" at an artist's work created over a span of years. Once you have retrospective and retrospection behind you, you can also add their kin retrospect (most familiar in the phrase in retrospect to describe thinking about the past or something that happened in the past) and retro (usually meaning "fashionably nostalgic or old-fashioned") to your vocabulary, too.

Merriam-Webster's Word of the Day for December 30, 2025 is: charisma • \kuh-RIZ-muh\ • noun Charisma refers to a special magnetic charm or appeal that causes people to feel attracted and excited by someone. A person with charisma is captivating and often admired. // The young singer has the kind of charisma that turns a performer into a star. See the entry > Examples: "Sports and showbiz have gone hand in hand since newsreels in the 1920s showcased the skills and charisma of Babe Ruth." — Carole Horst, Variety, 16 July 2025 Did you know? The Greek word charisma means "favor" or "gift." It comes from the verb charizesthai ("to favor"), which in turn comes from the noun charis, meaning "grace." In English, charisma was originally used in Christian contexts to refer to a gift or power bestowed upon an individual by the Holy Spirit for the good of the Church—a sense that is now very rare. These days, we use the word to refer to social, rather than divine, grace. For instance, a leader with charisma may easily gain popular support, and a job applicant with charisma may shine in an interview.

Merriam-Webster's Word of the Day for December 29, 2025 is: nefarious • \nih-FAIR-ee-us\ • adjective Nefarious is a formal word that describes something as evil or immoral. // Authorities suspect that the recovered materials were going to be used for nefarious purposes. See the entry > Examples: “Introducing characters like Gorilla Grodd on DC Crime would help familiarize audiences with these figures before they potentially receive an expanded role in another project. Perhaps each season could focus on a different villain, highlighting their nefarious actions.” — Chris Agar, comicbook.com, 16 Nov. 2025 Did you know? If you need a fancy word to describe someone who’s up to no good, nefarious has got you (and them) covered. It’s also handy for characterizing the “no good” such a dastardly devil gets up to, as in “a nefarious business/plot/deed.” Nefarious is most often used for someone or something that is flagrantly wicked or corrupt—it’s more applicable to the mustache-twirling supervillain than the morally gray antihero. In other words, there’s no question that a nefarious scheme, or schemer, is not right. Etymologically, this makes perfect sense: nefarious can be traced back to the Latin noun nefas, meaning “crime,” which in turn combines ne- (“not”) and fas, meaning “right” or “divine law.” It is one of very few English words with this root, accompanied only by the likes of nefariousness and the thoroughly obscure nefast (“wicked”).

Merriam-Webster's Word of the Day for December 28, 2025 is: yen • \YEN\ • noun A yen is a strong desire, urge, or craving for something. // After dinner, the family went out for ice cream to satisfy their yen for something sweet. // Students with a yen to travel should consider studying abroad. See the entry > Examples: “If you’ve got a yen for succulent, right-off-the-boat Maine sea scallops, now is the time to get them.” — Stephen Rappaport, The Bangor Daily News, 26 Mar. 2025 Did you know? Although yen suggests no more than a strong desire these days (as in “a yen for a beach vacation”), at one time someone with a yen was in deep trouble: the first meaning of yen, used in the late 19th century, was an intense craving for opium. The word comes from yīn-yáhn, a combination of yīn, meaning “opium,” and yáhn, “craving,” in the Chinese language used in the province of Guangdong. In English, the Chinese syllables were translated as yen-yen, and eventually shortened to yen.

Merriam-Webster's Word of the Day for December 27, 2025 is: apropos • \ap-ruh-POH\ • preposition Apropos is used as a preposition to mean "with regard to." It is frequently used in the phrase "apropos of." // Sean interrupted our conversation about politics and, apropos of nothing, asked who we thought would win the basketball game. As an adjective, apropos describes something that is suitable or appropriate, as in "an apropos nickname." See the entry > Examples: "Once, at the height of COVID, I dropped off a book at the home of Werner Herzog. I was an editor at the time and was trying to assign him a review, so I drove up to his gate in Laurel Canyon, and we had the briefest of masked conversations. Within 30 seconds, it turned strange. 'Do you have a dog? A little dog?' he asked me, staring out at the hills of Los Angeles, apropos of nothing. He didn't wait for an answer. 'Then be careful of the coyotes,' Herzog said." — Gal Beckerman, The Atlantic, 8 Jan. 2025 Did you know? Apropos wears its ancestry like a badge—or perhaps more fittingly a beret. From the French phrase à propos, meaning "to the purpose," the word's emphasis lands on its last syllable, which ends in a silent "s": \ap-ruh-POH\. Apropos typically functions as an adjective describing what is suitable or appropriate ("an apropos comment"), or as a preposition (with or without of) meaning "with regard to," as in "apropos (of) the decision, implementation will take some time." The phrase "apropos of nothing" is used to signal that what follows does not relate to any previous topic.
