However, depending on the context, you could use:
* ਪਿਆਰੀ (pyaari): This means "beloved" or "sweetheart" and is a common term of endearment.
* ਪਿਆਰ (pyaar): This literally means "love" but can be used to refer to a girlfriend.
* ਸਾਥੀ (saathi): This means "partner" or "companion" and can be used to refer to a girlfriend in a more casual way.
Ultimately, the best way to refer to your girlfriend in Punjabi will depend on your relationship and how comfortable you are with the person.
