How to Say Shut Up in French - From Chut to Ta Gueule

The neutral way to say shut up in French is tais-toi (to one person) or taisez-vous (formal/plural), from the verb se taire. Chut means “shh.” Ferme-la is rude, and ta gueule - literally “your muzzle” - is genuinely vulgar: understand it in films, but don’t use it.

The severity scale (the core table)

Se taire: the verb behind tais-toi

Se taire (to be/fall silent) is a reflexive verb - imperative forms: tais-toi / taisons-nous / taisez-vous. One genuinely useful, self-deprecating phrase: je me tais (I’ll shut up / I’ll say no more) - a graceful way to end your own point. Past tense (advanced note): elle s’est tue (she went silent). For the reflexive pattern this belongs to, see French conjugation guide.

Ta gueule: why it’s so rude (and so common in movies)

Gueule is an animal’s mouth or muzzle - applying it to a human is inherently degrading, which is exactly why the phrase carries so much bite. Paradoxically, it’s extremely common among (typically male) friends as jokey banter, but tone-dependent in a way that’s risky to read as an outsider. As a learner, the safe rule: receive it, don’t send it. A much safer jokey alternative for banter: oh, ça va ! (drop it! / oh come on!). For the fuller vulgarity spectrum this word belongs to, see French swear words guide.

Polite ways to actually quiet a room

For teachers, parents, and meetings: un peu de silence, s’il vous plaît, on se calme (settle down), écoutez-moi (listen to me), a simple chut with a gesture, or the conversational boundary-setter est-ce que je peux finir ? (may I finish?).

Recap

Chut and tais-toi cover almost every real situation you’ll need - the rest of the scale is worth understanding for films and street conversation, not for deploying yourself. Register really is the whole story here: the same rough meaning ranges from “shh” to genuinely offensive depending entirely on which word you pick.
