Ça marche means “that works,” “sounds good,” or “okay/deal.” It’s how French speakers casually agree to something.

Literal meaning: “it walks” (from marcher, to walk/function). In use, it has nothing to do with walking — it’s an idiomatic stand-in for agreement.

Pronunciation: The French phrase “ça marche” is pronounced as sah marsh (IPA: /sa maʁʃ)

When to use it: Examples

• Confirming plans → “On se voit à 19h?” “Ça marche!” (See you at 7? Sounds good!)
• Agreeing to a task → “Tu peux envoyer le fichier?” “Ça marche.” (Can you send the file? Will do.)

Register: Informal. Fine with friends, colleagues, service staff. Avoid in formal writing or with someone you’d address as vous in a professional context.

vs. “D’accord”: Both mean agreement, but ça marche is warmer/more casual; d’accord is neutral and works in more formal settings.
