je ne sais quoi

[zhuh nuh se kwa]

What does je ne sais quoi mean?

Je ne sais quoi literally means "I don't know what" in French.


The phrase was borrowed into English as an expression of a quality that makes something or someone attractive, distinctive, or special in some way, but is hard to put into words.

I think that the French je ne sais quoi is more about the attitude. But more tangibly it's about the details, whether that's beautiful jewellery, beautiful basics or just beautiful materials.

Where does je ne sais quoi come from?

The French phrase je ne sais quoi was borrowed into English as early as the 1650s to characterize some inexpressible, indefinable, or ineffable quality, such as some element that makes an engaging work of art or charismatic person special.

Often phrased “a certain je ne sais quoi,” the saying is similar to the English expression a certain something, although the original French has a kind of je ne sais quoi all its own, don’t you think?

Je ne sais quoi continued on in English through the centuries, used widely in speech and writing as a learned expression that can lend a text or utterance a sophistication—or pretentiousness.

While it has its fanciness, je ne sais quoi isn’t all highbrowIcelandic pop singer Hera Björk wrote and performed the well-liked (though not winning) “Je Ne Sais Quoi” for the 2010 Eurovision European song contest. In 2012, the popular English duo Pet Shop Boys released “A Certain ‘Je Ne Sais Quoi’,” a B-side to their hit track “Winner.”

In 2014, interest in je ne sais quoi spiked after it was the butt of a joke in a commercial by the fast-food restaurant Sonic. In it, two men are eating chicken wings when one says the chicken will be his wingman. The other scoffs at the idea that the chicken would give him a certain je ne sais quoi. The first man, ignorant of the expression and thinking it’s a girl named Jenna interested in him, responds “Jenna said what?”  


Who uses je ne sais quoi?

Je ne sais quoi can be used to express the inexpressible in a way that can variously sound smart, worldly, or French-y. The “special sauce” that je ne sais quoi conveys is almost always positive or desirable in some way.

Sometimes its use is earnest, other times a parody of fancy talkers.
