Formal:
* ତୁମେ କ'ଣ କରୁଛ? (Tume ka'na karuchha?) - This is the most common and polite way to ask.
* ଆପଣ କ'ଣ କରୁଛନ୍ତି? (Apan ka'na karuchhanti?) - This is even more formal and respectful, used when addressing someone older or of higher status.
Informal:
* ତୁ କ'ଣ କରୁଛ? (Tu ka'na karuchha?) - This is a more casual way to ask a friend or someone you know well.
* କ'ଣ କରୁଛ? (Ka'na karuchha?) - This is a very informal way to ask, used with close friends or family.
Note:
* The pronunciation of 'ch' in Odia is similar to the 'ch' in "chair".
* The 'a' in "ka'na" is a short, unstressed vowel.
* The 'u' in "karuchha" is pronounced like the 'oo' in "moon".
Remember, the level of formality you use will depend on the context and your relationship with the person you are speaking to.
