[tlhIngan Hol] is {ghaHvaD nuq Dapong} correct ?

There's something I'm wondering, with regards to the {ghaHvaD nuq Dapong}. Lets assume, I want to ask someome, how someone is called. And I say: {ghaHvaD nuq Dapong ?}. There's something in this sentence, that seems weird to me.. Assume the guy's name is "peter". The word "peter", takes the place of {nuq}, so the person asked, could probably reply by saying: {ghaHvaD peter vIpong}. But then we would have nuq = peter. But how can "peter" be a "what" ? Isn't "peter" a "he" ? ~ mayqel qunen'oS the ancient cat I want alive the rest I'll grind beneath my boot
