ferme le / la
tais-toi
fermer la bouche
ferme la porte
taisez-vous tous
"Fermez la bouche!" (pronounced FER-meh lah BOOSH) is the popular way of saying "Shut up." Literally it means, "Shut the mouth." You don't say "your" when describing one's body parts. For "shut your face" you would say "Fermez le visage!" (pronounced FER-meh luh vee-SAHZH) but it may be mistranslated by a french speaker as idiocy. Also, "ta gueule !"
That could be said 'ferme-la !' in French. Not something you would say to your boss.
ferme-la ! (of course this is quite direct and even offensive)
garder ma bouche a fermé fermement
taisez-vous s'il vous plaît (polite version) or "fermez-la !" which is the angry way of saying it.
Fermer
Tais-toi et on ne me parle pas, alcoolique.
