Hafa Adai?
This is a very common and versatile phrase that can be used in many situations, similar to "hello" in English. It literally translates to "what is it?" but it is often used to mean "what are you doing?" or "what's up?".
Here are some other ways to say "what are you doing?" in Chamorro, depending on the context:
* Para hafa ma'mo'na'? (What are you doing now?)
* Hu håna'i håna'i? (What are you up to?)
* Hu håna'i ma'mo'na'? (What are you doing right now?)
Remember that Chamorro is a very expressive language, and there are many ways to say the same thing depending on the situation and your relationship with the person you're talking to.
