Merriam-Webster's Word of the Day

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





empirical • \im-PEER-uh-kul\ • adjective

When we describe something, such as data, as empirical, we mean that it originated in, or was based on, observation or experience. Empirical can also be used to describe something that can be verified or disproved by observation or experiment, as in “empirical laws.”

// The team of conservation biologists has over the years collected reams of empirical data, from species inventories to soil analyses.

Examples:

“She speaks the language of food chemistry and can tell you, based on empirical facts, why raspberry should never be boiled if you want the taste of raspberry rather than the taste of raspberry jam, and why coffee and tomato, which share several of the same volatile compounds, taste obviously right together despite sounding obviously wrong.” — Maria Gunko, The California Courier (Glendale, California), 30 July 2026

When empirical first appeared as an adjective in English, it meant simply “in the manner of an empiric.” In the ancient world, empirics were members of a sect of doctors who practiced medicine using treatments observed to be clinically effective, rather than treatments based on theoretical principles. This all sounds fine and good to a modern reader, but empirics were in direct opposition to Galen, the 2nd century Greek physician whose theories and practices (including the theory of bodily humors) dominated medicine in Europe from the Middle Ages until the mid-17th century. As the underdogs in this rivalry, empirics took some reputational hits, evidenced by the use of empiric to refer to someone who disregards or deviates from the rules of science or accepted practice; to be called an empiric was sometimes like being called a quack or charlatan. Empirical can still be used critically to describe ideas and practices that rely on experience or observation alone and without due regard for system or theory. But, perhaps in a bit of a case of “the Empirics strike back,” empirical more often keeps its narrower sense, and is used positively to describe evidence and information grounded in observation and experience, or capable of being verified or disproved by observation or experiment.

shofar • \SHOH-far\ • noun

A shofar is the horn of an animal (usually a ram) blown as a trumpet by the ancient Hebrews in battle and during religious observances. It is used in modern Judaism especially during Rosh Hashanah and at the end of Yom Kippur.

Examples:

“Sheep were domesticated in ancient Mesopotamia over ten thousand years ago and we have the ancient cave paintings to prove it. Sheep appear in folklore, religion, and mythology from all over the world: the Greek golden fleece, the Jewish shofar, the Egyptian Pharaoh’s shepherd’s crook, Christianity’s Agnus Dei.” — Celia Mattison, Literary Hub, 30 Oct. 2025

One of the shofar’s original uses was to proclaim the Jubilee year (a year of emancipation of enslaved Jews and restoration of alienated lands to their former owners). Today, it is mainly used in synagogues during the High Holidays. It is blown daily, except on Shabbat, during the month of Elul (the 12th month of the civil year or the 6th month of the ecclesiastical year in the Jewish calendar), and is sounded a number of times during the Rosh Hashanah services, and again at the end of the last service (known as neilah) on Yom Kippur. The custom is to sound the shofar in several series that alternate shorter notes resembling sobbing and wailing with longer unbroken blasts.

Examples:

“My whole attitude has been—because all I care about is the music—I don’t need to make the scene. I don’t need to hobnob with the executives because I see them all the rest of the year.” — Jem Aswad, quoted in Variety, 14 Apr. 2026





Did you know?

In William Shakespeare’s Twelfth Night, Sir Toby Belch warns Viola that Sir Andrew wants to duel, telling her “‘Hob, nob’ is his word” and then adding the gloss “give’t or take’t.” In today’s English, he might have said “take it or leave it.” Sir Toby’s hob, nob is an alteration of hab nab (“hit or miss,” “however things may turn out”), itself likely a shortening of the Middle English phrase habbe or nabbe (“whether I have or don’t have”). After Shakespeare’s day, hob-nob and hob or nob were used adverbially to mean “randomly.” And to drink hobnob, or hob or nob, was to take turns with one’s drinking buddies toasting each other’s health. Later, hobnob (as well as hob or nob, hob-a-nob, etc.) was verbified to mean “to drink socially” and then, dropping the booze, “to spend time with someone in a friendly way.” Today hobnob is used especially in situations where someone is chatting up someone famous or important, as in “hobnobbing with celebs.”

Merriam-Webster's Word of the Day for September 11, 2026 is:





patina • \puh-TEE-nuh\ • noun

A patina is a usually green film that forms on copper and bronze that is exposed to moist air for an extended time. The word patina can also refer to a shiny or dark surface that over time forms naturally on something (such as wood or leather), or to a literal or figurative thin layer.

// The town erected a statue in her honor, which over the years developed a seafoam green patina.

// Although the winery is brand-new, it has been constructed and decorated to give it a patina of old-world quaintness.

Examples:

"Family, friends and neighbors filled the frames with dancing and dominoes; their apartments painted in shades of mint, butter yellow and ... pink, flecked with a patina cultivated by humidity and time." — Suzy Exposito, The Los Angeles Times, 28 July 2026





Did you know?

When Italians applied the word patina to the green film that forms on the surface of copper, they were drawing from Latin, in which patina means "a shallow dish." (Presumably, the Italian meaning developed from the observation of such film forming on copper dishes.) By the mid-18th century, English speakers were also calling the green film patina, and by the 20th century, they'd expanded the word's application to surface appearances of things that have grown more beautiful with age or use—think of an old wooden desk or a tarnished silver goblet. Use of the word to refer to thin layers both literal and figurative ("a patina of grime," "a patina of respectability") followed soon after. The related verb patinate means "to give a patina to."

Examples:

“On these runs, I was loath to stop. I dreaded zebra crossings and the city-center pavements, and instead ran into the surrounding countryside, abandoning myself to the endless roads that seemed to be going nowhere.” — Madeline Potter, The Roma: A Traveling History, 2025





Did you know?

Loath as some language sticklers may be to accept it—indeed, they may loathe the fact—loathe is an accepted, though less common, spelling variant of the adjective loath. The language sticklers know that loathe is most often used as a verb meaning "to hate," and their desire to keep the language tidy by letting loath alone mean "not willing or wanting to do something" is understandable. But here’s the rub: language is very often untidy. Both loath and loathe trace back to the Old English word lāth, meaning “loathsome, disgusting.” Each has had a number of variant spellings over the years, and for at least some portion of their history each word has taken on the spelling of the other. If you would like to keep the two distinct according to prevailing preferences, remember that loath is how you feel (reluctant, unwilling), and loathe is what you do (hate, dislike).
