How do you say how are in Portuguese?

"How are you?" in Portuguese can be expressed in a few ways depending on the formality and context:

Formal:

* Como está? (pronounced: koh-moh eh-stah) - This is the most formal way to ask "How are you?" and is used when addressing someone older than you, in a professional setting, or someone you don't know well.

* Como vai? (pronounced: koh-moh vy) - Similar to "Como está?", this is also formal and can be used in the same situations.

Informal:

* Como estás? (pronounced: koh-moh eh-stahs) - This is the informal version of "Como está?" and is used with friends, family, and people you know well.

* Tudo bem? (pronounced: too-doo bem) - This literally means "Everything okay?" and is a common way to ask "How are you?" in a casual setting.

* E aí? (pronounced: eh-ee) - This is a very informal greeting that can be used with friends and family, similar to "What's up?" in English.

It's important to note that there are regional variations in Portuguese. In Brazil, for example, "Tudo bem?" is the most common way to ask "How are you?" even in formal situations.
