Did you know?

Anybody who has had basic Latin knows that alma mater, a fancy term for the school you attended, comes from a phrase that means "fostering mother." If mater means "mother," then matriculate probably has something to do with a school nurturing you just like good old mom, right? Not exactly. If you go back far enough, matriculate is distantly related to the Latin mater, but its maternal associations were lost long ago—even in terms of Latin history. It is more closely related to the Late Latin word matricula, which means "public roll or register." Matricula has more to do with being enrolled than being mothered, but it is the diminutive form of the Latin noun matrix, which in Late Latin was used in the sense of "list" or "register" and earlier referred to female animals kept for the purposes of breeding.

Examples:

“The 70-year-old retiree from South Philadelphia ordinarily would avoid bees out of fear, but this spring she suited up for a study on therapeutic beekeeping at the Half Mad Honey apiary in the Navy Yard. Led by Temple University occupational therapy student Meghan Robertson, the project tested if beekeeping could improve mental health and well-being in older adults.” — Kayla Yup, The Philadelphia Inquirer, 28 June 2026





Did you know?

For those who enjoy honey and the fascinating creatures that make it, apiaries are the bee’s knees. The word apiary—which comes ultimately from the Latin word apis, meaning “bee”—can refer to any place where bees are kept, but is used especially for a collection of hives or colonies of bees kept for their honey. Honeybee colonies are highly complex clusters of individuals that function virtually as single organisms (as by a hive mind). Queen bees, capable of laying more than a thousand eggs per day, develop from larvae that are fed solely on royal jelly. Drones are stingless male bees whose one job (they do not gather nectar or pollen) is to mate with the queen. Drones are vastly outnumbered by tens of thousands of female worker bees who do everything else—from foraging and feeding (royal jelly is produced from their pharyngeal glands) to cleaning and defense. In other words, they run the hive.

Merriam-Webster's Word of the Day for September 3, 2026 is:





recalcitrant • \rih-KAL-suh-trunt\ • adjective

Recalcitrant is a formal word typically used to describe someone who stubbornly refuses to obey rules or orders. Recalcitrant can also describe something that is difficult to manage or operate.

// The magazine, aimed at parents and caregivers of young children, will include the latest in child development science as well as practical information, like tricks for persuading even the most recalcitrant toddler to cooperate.

Examples:

“One particularly recalcitrant driver … managed to rack up 29 speeding tickets during the 10-school-day span.” — Dave Werner, The Press-Republican (Plattsburgh, New York), 20 May 2026





Did you know?

When given an order or command, a recalcitrant person (or animal) digs in their heels. They will not give an inch, so to speak, immovable in their determination to defy the rules. This makes a great deal of sense, etymologically, as recalcitrant traces back to calx, the Latin word for “heel.” (Calx is also responsible for such English words as calcaneus, “the large bone of the human heel,” and—mention this at your next pizza party—calzone.) From calx, Latin users formed first the verb calcitrare (“to kick”) and then recalcitrare (“to kick back”). In Late Latin, recalcitrare was used figuratively to mean “to be stubbornly disobedient,” leading to the English adjective we apply today to stubborn mules both human and asinine.

Merriam-Webster's Word of the Day for September 2, 2026 is:





dissonant • \DISS-uh-nunt\ • adjective

Dissonant typically describes music that is not in harmony, or sounds and notes that clash. In non-music contexts, dissonant describes things that clash by not being in agreement or by not fitting well together.

// The guitarist struck a dissonant chord.

// The retrospective provided a sometimes dissonant journey through the artist's decades of work.

Examples:

"Their disparate sonic elements form a dissonant but cohesive whole, wisps of trumpet and electronic woodwinds flashing by as quickly as flickering subway car lights." — Sam Goldner, Pitchfork, 23 July 2026





Did you know?

At the root of dissonant is the Latin verb sonare. Can you guess what sonare means? Here's a hint: some related words are sonata, supersonic, and resonance. Does it sound to you as if sonare has something to do with sound? To invoke an approving sound in response: ding ding ding. In fact, sonare means "to sound," is related to the Latin noun sonus (meaning "sound"), and is also an ancestor of the English word sound. In musical contexts, dissonant and the related noun dissonance are used to describe a clashing or unresolved musical interval or chord. Consonance, in contrast, refers to a musical interval or chord that produces an impression of agreeableness or resolution.

Examples:

“Earth-friendly, conscientious gardeners learn to slow down and pay attention not only to plants but to the many creatures that share the garden. ... The garden teaches us valuable lessons. It reminds us that balance is achieved not through sorting the natural world into neat categories, but by respecting nature and allowing it to reveal to us its own complicated, interdependent and beautiful gray areas.” — Rita Perwich, The San Diego Union-Tribune, 4 July 2026





Did you know?

As Mahatma Gandhi once wrote, “There is a higher court than courts of justice, and that is the court of conscience.” A person who is conscientious makes sure that they are judged well by such a court. This is true for someone who is “governed by their conscience” as the oldest sense of the word is defined—as in “a conscientious leader”—but it is also true for the conscientious person paying close, careful attention to the task at hand. Conscientious came to English from French, centuries after Middle English had adopted conscience from Anglo-French; both ultimately come from the Latin verb scire, meaning “to know.”
