Examples:

“Bosley Crowther, chief film critic for The New York Times, didn’t quite know what to make of Dr. Strangelove at the time of its release in January 1964. … What exactly was Kubrick’s point? ‘…I want to know what this picture proves.’ We may find it odd for an influential critic to expect a movie to ‘prove’ anything. Kubrick’s aim was manifestly not to prove, but to subvert and discomfit.” — Andrew J. Bacevich, The Nation, 23 Mar. 2023

Did you know?

Disconcerted by discomfit and discomfort? While the two look similar and share some semantic territory, they’re etymologically unrelated. Unlike discomfort, discomfit has no connection to comfort, which comes ultimately from the Latin adjective fortis, meaning “strong.” Instead, discomfit was borrowed from Anglo-French in the 13th century with the meaning “to defeat in battle.” Within a couple centuries, discomfit had expanded beyond the battlefield to mean “to thwart,” a meaning that eventually softened into the now-common “to disconcert or confuse” use—one quite close to the uneasiness and annoyance communicated by discomfort. For a time, usage commentators were keen to keep a greater distance between discomfit and discomfort; they recommended that discomfit be limited to its original “to defeat” meaning, but they’ve largely given up now, and the “disconcert or confuse” meaning is fully established. There is one major difference between discomfit and discomfort, though: discomfit is used almost exclusively as a verb, while discomfort is much more commonly used as a noun than a verb.
