How can we say how are you in Tamil?

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

Formal:

* சுகமா? (Sukama?) - This is the most common and polite way to ask "how are you?"

* நலமா? (Nalmaa?) - This is another formal way to ask, slightly more formal than "sukama?"

Informal:

* எப்படி இருக்கீங்க? (Eppati irukkinga?) - This is a more informal and friendly way to ask "how are you?"

* எப்படி இருக்கீங்க? (Eppati irukkinga?) - This is a very informal way to ask "how are you?" usually used among friends or family.

You can also add the word "சாரி" (saari) after the phrase for extra politeness.

For example:

* சுகமா சாரி? (Sukama saari?) - How are you? (formal and polite)

* எப்படி இருக்கீங்க சாரி? (Eppati irukkinga saari?) - How are you? (informal and polite)

It's best to use the appropriate phrase based on your relationship with the person you are talking to.
