Here's a breakdown:
* ningal (നിങ്ങള്): you (plural, formal)
* ethraare (എത്രാറെ): how are you (literally, "how are you [feeling]?)
Note: "ningal" is used as a polite form when addressing someone you don't know well or when you're showing respect. If you're addressing someone you know well and are comfortable with, you can use the more informal "nee" (നീ) for "you" (singular, informal).
Here are some other ways to say "how are you" in Malayalam, depending on the context:
* "ningalkku ethraare?" (നിങ്ങള്ക്കു എത്രാറെ?): "how are you?" (more formal than "ningal ethraare?")
* "ningalkku sahyaamallo?" (നിങ്ങള്ക്കു സഹ്യമാണല്ലോ?): "are you okay?" or "are you alright?"
* "ningalkku njaanangalulla?" (നിങ്ങള്ക്കു ഞാങ്ങളുള്ള?): "how are you doing?" (more informal)
You can also use "sukkhama?" (സുഖമാ?) which literally means "are you well?". This is a very common way to ask how someone is, but it can be a bit formal in some contexts.
