I assume you are asking how to say "what is this" in Arabic. There are a few ways to say it, but the most common one is "ما هذا؟" which is pronounced as "maa hadha?". Another way to say it is "ما هذه الشيء؟" which is pronounced as "maa hadhihi alshay?". Both of these phrases mean "what is this?" and can be used interchangeably.
