faux pas

Faux pas is French: faux meaning 'false' and pas meaning 'step.' A faux pas is a false step, a misstep, a stumble. In dance and in formal ceremony, there is a prescribed movement, a choreography everyone is expected to know. A false step breaks the pattern. Everyone notices.

The phrase entered English from French in the 1670s, and it was always social. To commit a faux pas was to violate an unwritten rule of conduct—to say something inappropriate at dinner, to wear the wrong thing to a party, to call someone by the wrong name. The metaphor is precise: society operates like a dance, and if you step wrong, you're visibly out of step.

Faux pas differs from crime or sin. Those are violations of explicit rules written down and enforced. A faux pas is a violation of implicit rules—the choreography everyone is assumed to know. You're judged not for breaking law but for breaking rhythm.

In an age of informal communication and casual dress, faux pas seems less applicable, but it survives. The word remains the only one that captures the particular shame of doing something that isn't wrong per se, but is wrong socially—visible, noticed, marking you as someone who didn't know the steps.
