Here are a few ways to say that in Hindi:
* आप और क्या कहना चाहते हैं? (aap aur kya kahna chahte hain?) - This is the most literal translation and is a polite way to ask.
* आपका क्या मतलब है? (aapka kya matlab hai?) - This is a bit more direct and can be used if you're confused or want to clarify.
* और क्या कहना चाह रहे हैं? (aur kya kahna chah rahe hain?) - This is a more casual way to ask and can be used with friends or family.
The best way to choose the right translation depends on the context and your relationship with the person you're speaking to.
