Formal:
* ਤੁਸੀਂ ਕਿੱਥੇ ਹੋ? (Tusi kiethe ho?) - This is the most formal way to ask.
* ਤੁਹਾਡਾ ਕਿੱਥੇ ਹੈ? (Tuhāda kiethe hai?) - This is also formal, but more literally means "where is your place?"
Informal:
* ਤੂੰ ਕਿੱਥੇ ਐਂ? (Tūn kiethe ān?) - This is the most common way to ask someone where they are.
* ਕਿੱਥੇ ਆ? (Kithe ā?) - This is even more informal and can be used with close friends or family.
Note: The pronunciation of Punjabi words can be challenging for non-native speakers. It's best to use a pronunciation guide or listen to a native speaker.
