How to say "Danke" in Vietnamese

In Vietnamese, saying cảm ơn is the basic way to show gratitude, but the level of politeness changes with age, relationship, and context. Adding the polite particle ạ or using the appropriate kinship term (anh, chị, em, bạn) signals respect. Use the plain cảm ơn with strangers or in casual settings, and switch to the more formal variants when speaking to elders, teachers, or anyone you want to show deference to.

1. General, neutral thanks

• Cảm ơn!
  "Thank you!"

2. Thanking someone older or of higher status – attach the polite particle ạ and the appropriate kinship term.

• Cảm ơn anh ạ!
  "Thank you, sir!"
• Cảm ơn chị ạ!
  "Thank you, ma'am!"

3. Thanking a peer or a friend – you can keep it simple or add a friendly particle nhé.

• Cảm ơn bạn!
  "Thanks, friend!"
• Cảm ơn nhé!
  "Thanks, okay?"

4. Thanking a younger person – use em (younger sibling) or cậu (younger male friend).

• Cảm ơn em!
  "Thank you, younger sibling!"
• Cảm ơn cậu!
  "Thanks, buddy!"

5. Expressing deep gratitude – add rất nhiều (a lot) or đã giúp tôi (for helping me).

• Cảm ơn rất nhiều!
  "Thank you very much!"
• Cảm ơn bạn đã giúp tôi!
  "Thank you for helping me!"
