Examples:

“Meanwhile, officials are having high-level conversations about the long-term effectiveness of Michigan’s aging dam infrastructure and the growing need for effective flood mitigation measures. Whitmer noted a Gordian knot of complexity around the state’s dams, many of which are operated through murky public-private arrangements.” — Byron McCauley, The Holland (Michigan) Sentinel, 23 Apr. 2026

According to legend, when the peasant Gordius became king of Gordium, capital of the ancient district of Phrygia (in what is now modern Türkiye), he fastened the yoke of his wagon to a beam with a very complex knot. Centuries later, when Alexander the Great arrived on the scene, he was told that he couldn’t conquer and rule Asia unless he proved himself worthy by untying the knot. Alexander quickly solved his problem—and gained a new kingdom—by slicing the knot in half with his sword. Since then, Gordian knot has been a term for a difficult problem, and the phrase “cut the Gordian knot” has been a way to describe a direct and forceful solution to an apparently insurmountable difficulty.

sacrosanct • \SAK-roh-sankt\ • adjective

Sacrosanct is a formal word that describes something too important and respected to be changed or criticized. It can also mean "most sacred or holy."

Examples:

"Sen. Paul Strommen of Sidney ... said there's no appetite among senators to empty the Veterans Aid Fund. 'There's certain things that are kind of sacrosanct, and veterans' aid is one of those things.'" — Todd von Kampen, The North Platte (Nebraska) Telegraph, 7 Mar. 2026





Did you know?

Contrary to the beliefs of some, language is not sacrosanct; rather, it is subject to constant modification based on the needs, experiences, and even whims of those who use it. Take the word sacrosanct itself, which likely comes from the Latin phrase sacro sanctus meaning "made holy by a sacred rite." There's a definite semantic softening from that to the "too important and respected to be changed or criticized" meaning of sacrosanct. But holy moly, has sanctus led to a whole bunch of other English words with a truly pious flavor, from saint and sanctimony to sanctify and sanctuary. Sacrum ("a sacred rite"), source of the sacro in sacro sanctus, is no slouch either, living on in English anatomy as the name for our pelvic vertebrae—a shortening of os sacrum, which translates literally as "holy bone."

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





onus • \OH-nuss\ • noun

Onus is a formal word typically used to refer to a responsibility, obligation, or burden. It is usually preceded by the word the.

// Management has made it clear that the onus is on employees to ask for further training if they don’t understand the new procedures.

Examples:

“The [London Book Fair] comes the week before the government is due to deliver its progress report on AI and copyright, after proposals for a relaxation of existing laws caused outrage last year. Philippa Gregory, the novelist, described the plans for an ‘opt-out’ policy, which puts the onus on writers to refuse permission for their work to be trawled, as akin to putting a sign on your front door asking burglars to pass by.” — The Guardian (London), 13 Mar. 2026





Did you know?

Understanding the etymology of onus shouldn’t be a burden; it’s as simple as knowing that English borrowed the word—spelling, meaning, and all—from Latin in the 17th century. Onus is also a distant relative of the Sanskrit word anas, meaning cart (as in, a wheeled wagon or vehicle that carries a burden). English isn’t exactly loaded with words that come from Latin onus, but onerous (“difficult and unpleasant to do or deal with”) is one, which is fitting since in addition to being synonymous with “burden,” onus has also long been used to refer to obligations and responsibilities that one may find annoying, taxing, disagreeable, or distasteful.

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

To expedite something is to cause it to happen faster.

// We’ll do what we can to expedite the processing of your application.

Examples:

“The new task force ... is required to submit an initial report in 60 days and final report in 90 days with recommendations to simplify, improve and expedite hiring.” — Blake Paterson, NOLA.com (New Orleans, Louisiana), 7 Apr. 2026





Did you know?

Need someone to do something in a hurry? You can tell that person to step on it, or you can tell them to expedite it. Figurative feet are involved in both cases, though less obviously in the second choice. Expedite comes from the Latin verb expedire, meaning “to free from entanglement or difficulty.” The feet come in at that word’s root: it traces back to Latin ped- or pes, meaning “foot.” Expedient and expedition also stepped into English by way of expedire.

Merriam-Webster's Word of the Day for May 22, 2026 is:





fraught • \FRAWT\ • adjective

Fraught describes something that causes or involves a lot of emotional stress or worry. When fraught is used in the phrase “fraught with,” it means “full of something bad or unwanted.”

// The siblings had a fraught relationship.

// The paper was poorly researched and fraught with errors.

Examples:

"We might think replicating one of these ideas will deliver that perfectly walkable, equitable, sustainable and prosperous city of our hopeful imagination. Not likely. Many of these were hard wins, often fraught and contested in their local context." — Gia Biagi, The Chicago Tribune, 5 Apr. 2026





Did you know?

An early instance of the word fraught occurs in the 14th century poem Richard Coer de Lyon, about England's King Richard I, aka Richard the Lionheart. The line "The drowmound was so hevy fraught / That unethe myght it saylen aught" describes a large fast-sailing ship so heavily fraught—that is, loaded—that it can barely sail. The poet's use of fraught is typical for the time; originally, something that was fraught was laden with freight. For centuries, fraught continued to be used in relation to loaded ships, but that use is now considered archaic. These days, fraught is used in reference to situations that are heavy with tension, emotion, or some other weighty characteristic.
