How you say how are in Thai?

There are a few ways to say "how are you" in Thai, depending on the level of formality and the context:

Formal:

* สบายดีไหม (sa-bai-dee mai)? This is the most common and polite way to ask "how are you?" It literally translates to "are you well?"

* เป็นอย่างไรบ้าง (bpen yaang rai baang)? This is a slightly more formal way to ask "how are you?" It literally translates to "how are things?"

Informal:

* สบายดีไหม (sa-bai-dee mai)? This is the same as the formal version, but it can also be used in informal settings.

* เป็นไงบ้าง (bpen ngai baang)? This is a casual way to ask "how are you?"

* สบายดี (sa-bai-dee)? This is a very casual way to say "how are you?" and it can be used with friends and family. It literally translates to "are you well?"

Note:

* You can also use ดี (dee) which means "good" after these phrases to express "I'm good" or "I'm doing well." For example, "สบายดี ดี" (sa-bai-dee dee) means "I'm good" or "I'm doing well."

* When responding to "how are you?", you can use the same phrases as above to say "I'm good." For example, "สบายดี (sa-bai-dee)."

It's always a good idea to use a formal greeting when you're unsure of the level of formality.
