How do you say thank very much in portuguese?

There are a few ways to say "thank you very much" in Portuguese, depending on the formality and region:

Formal:

* Muito obrigado (male)

* Muito obrigada (female)

Informal:

* Muito obrigado (male, used for both genders in informal situations)

* Valeu! (informal, more common in Brazil)

* Obrigado(a)! (less formal than "muito obrigado(a)")

More expressive:

* Obrigado(a) de coração! (Thank you from the heart!)

* Agradeço muito! (I appreciate it very much!)

You can also add "por tudo" (for everything) after any of these phrases for a more comprehensive thank you.

Remember that Portuguese has two major dialects: European Portuguese and Brazilian Portuguese. While the phrases listed above are generally understood in both, some regional variations exist.
