The quintessential demonstration of “lugubrious” is the character Eeyore from “Winnie the Pooh.” This eternally sad donkey expects the worst of everything, but his friends still love him. “Lugubrious” can be traced back to the Latin verb “lugēre,” which means “to mourn.” When the word entered English, it came to describe a demonstrative emotion, well beyond simple sadness. “Lugubrious” is an appropriately dramatic word for someone demonstrating over-the-top sadness.
