To help me understand what you're trying to say, please provide more context. For example:
* What is the subject of the sentence? Are you asking about a specific item, concept, or person?
* What is the overall meaning you're trying to convey? Are you asking for someone's opinion, comparing something, or asking for clarification?
Here are some possible translations depending on the context:
* "What is it, and what about you?" - _Qu'est-ce que c'est, et toi ?_
* "What is it, and what do you think?" - _Qu'est-ce que c'est, et qu'en penses-tu ?_
* "What is it, and what do you have to say about it?" - _Qu'est-ce que c'est, et qu'as-tu à dire à ce sujet ?_
Please provide more information so I can give you the most accurate translation!
