Merriam-Webster's Word of the Day for July 3, 2025 is:
desultory \DEH-sul-tor-ee\ adjective
Desultory is a formal word used to describe something that lacks a plan or purpose, or that occurs without regularity. It can also describe something unconnected to a main subject, or something that is disappointing in progress, performance, or quality.
// After graduation, I moved from job to job in a more or less desultory manner before finding work I liked.
// The team failed to cohere over the course of the season, stumbling to a desultory fifth place finish.
“One other guy was in the waiting room when I walked in. As we sat there past the scheduled time of our appointments, we struck up a desultory conversation. Like me, he’d been in the hiring process for years, had driven down from Albuquerque the night before, and seemed nervous. He asked if I’d done any research on the polygraph. I said no, and asked him the same question. He said no. We were getting our first lies out of the way.” — Justin St. Germain, “The Memoirist and the Lie Detector,” New England Review, 2024

The Latin adjective desultorius was used by the ancient Romans to describe a circus performer (called a desultor) whose trick was to leap from horse to horse without stopping. English speakers took the idea of the desultorius performer and coined the word desultory to describe that which figuratively “jumps” from one thing to another, without regularity, and showing no sign of a plan or purpose. (Both desultor and desultorius, by the way, come from the Latin verb salire, meaning “to leap.”) A desultory conversation leaps from one topic to another, and a desultory comment is one that jumps away from the topic at hand. Meanwhile a desultory performance is one resulting from an implied lack of steady, focused effort.
