Examples:

“On opening night, the audience at St. Petersburg’s Alexandrinsky Theatre were mystified by The Seagull’s neither wholly comic nor wholly tragic tone, hissing and heckling throughout, with Chekhov fleeing from the gallery after the second act. It was only two years later, when Konstantin Stanislavski staged a more lugubrious take on The Seagull at Moscow Art Theatre, that it came to be recognized as a work of pure genius.” — Hayley Maitland, Vogue, 12 Feb. 2025

Did you know?

Everybody hurts, as the classic R.E.M. song goes, and when your day is long and the night is yours alone, lugubrious is a perfect word for describing such sorrowful feelings, or that which inspires them (a lugubrious song, perhaps). That said, if lugubrious strikes you as a tad unusual, no, no, no, you’re not alone. Lugubrious is the sole surviving English offspring of the Latin verb lugēre, meaning “to mourn.” Its closest kin, luctual, an adjective meaning “sad” or “sorrowful,” was laid to rest centuries ago.
