Which is the Spanish rendering of the English phrase Calm Down?

• A. Mantén la calma
• B. Relájese
• C. Cálmate
• D. Quedese Tranquilo

Answer: (D)

The concept here is choosing the right Spanish form to issue a direct command to lower arousal. For a casual, one-time instruction to someone you know, the natural rendering is Cálmate, the informal tú command of calmarse. That directly captures the sense of “Calm down” in the moment.

Mantén la calma translates to “Keep calm,” which is more about maintaining composure over time rather than telling someone to calm down right now. Relájese is a formal you (usted) command meaning “Relax,” which could be used in polite or official contexts. Quédese tranquilo is also formal and means “Stay calm,” again implying remaining in a calm state rather than the immediate act of calming down.

So, the best everyday translation of the imperative “Calm down” in casual speech is Cálmate. If formality is required, Cálmese or Relájese would be appropriate choices depending on the relationship and setting.
