How do you ask who is that in Kannada?

There are a few ways to ask "Who is that?" in Kannada, depending on the context and formality:

Informal:

* Avaru idare? (ಅವರು ಇದಾರೆ?) - This is the most common and straightforward way to ask.

* Yavudu idare? (ಯಾವುದು ಇದಾರೆ?) - This is more colloquial and can be used with friends or family.

Formal:

* Avaru? (ಅವರು?) - This is a shorter and more direct way to ask.

* Avara naamavaenu? (ಅವರ ನಾಮವೇನು?) - This means "What is their name?" and is a more polite way to ask.

For clarification:

* Avara yaaru endu tilidilla (ಅವರ ಯಾರು ಎಂದು ತಿಳಿದಿಲ್ಲ) - This means "I don't know who they are."

Remember to adjust your tone and wording based on the situation and your relationship with the person you are asking.
