It’s origin is the Latin word jejunus , which means without food, barren, so Jejune Literally means to intellectually starve to death.

The worst word in the English language, jejune just bleeds pomposity and snobbery. If you seriously use jejune in a sentence you a) are automatically an asshole and b) should be slapped across the mouth.

A word that sounds so terrible and random, that it is a top competitor for the worst word in the English language.

Does this word really sound like something that describes "naive, simplistic, and superficial"?
