In Spanish, there are several ways to say “shut up,” ranging from softer and polite to very rude. Use them carefully, because some can sound quite aggressive.

Soft or polite options

These are closer to “be quiet” or “could you stop talking,” and are safer in most situations:

  • Por favor, calla. – “Please, be quiet.”
  • Por favor, cállate. – “Please, shut up / be quiet.” (informal “you”)
  • Silencio, por favor. – “Silence, please.” (very common in class or meetings)
  • Haz silencio, por favor. – “Be quiet, please.”
  • Deja de hablar, por favor. – “Stop talking, please.”

Example mini-scene:

En la biblioteca, un estudiante dice:
“Oigan, por favor, guarden silencio , hay gente estudiando.” (“Hey, please keep silent, people are studying.”)

Neutral everyday “shut up”

These are common, but can sound rude depending on tone and context:

  • ¡Calla! – “Shut up / be quiet.” (can be neutral or annoyed)
  • ¡Cállate! – The classic “shut up!” to one person (informal).
  • ¡Cállense! – To several people: “Shut up, you all.”
  • Deja de hablar. – “Stop talking.” (straight to the point)
  • Basta, no quiero escuchar más. – “Enough, I don’t want to hear more.”

Example:

Dos amigos discuten y uno dice en tono de broma:
“¡Ya, cállate , siempre exageras!” (“Oh come on, shut up, you always exaggerate!”)

Harsher or more aggressive

Use these with caution; they can sound quite strong or offensive:

  • ¡Cállate la boca! – Literally “shut your mouth,” quite direct and rude.
  • Cierra la boca. – “Close your mouth.”
  • Cierra el pico. – Slangy “shut your trap.”

Example:

En una pelea fuerte alguien puede gritar:
“¡Cállate la boca y vete de aquí!” (“Shut your mouth and get out of here!”)

When you want a nicer alternative

If you don’t want to sound rude but need quiet, these are good substitutes:

  • ¿Puedes bajar la voz, por favor? – “Can you lower your voice, please?”
  • Oye, habla más bajito. – “Hey, speak more quietly.”
  • Hay gente trabajando/estudiando, ¿pueden hacer menos ruido? – “People are working/studying, can you make less noise?”

These convey the same idea as “shut up” but in a more socially acceptable way, especially with people you don’t know well or in formal settings.

TL;DR:

  • Most common: ¡Cállate! (informal), ¡Cállense! (plural).
  • Politer: Por favor, calla / cállate , Silencio, por favor , Haz silencio, por favor.
  • Harsher: Cállate la boca , Cierra la boca , Cierra el pico.
