Here are some other options, depending on the context:
* कुंडली (kuṇḍalī): This term refers to a small, round indentation, often used for dimples on the cheeks.
* छेद (ched): This translates to "hole" and can be used for dimples in general, but it's less common than "gadḍhā".
* खिंचाव (khincāv): This refers to a "pull" or "indent" and could be used for dimples on the body.
It's important to note that the specific word you choose will depend on the context and the specific type of dimple you are referring to.
