Two "question words" in one sentence One of my teachers asked us the example question:

你有什么安排吗？


I asked her why there would be two "question words", 什么 and 吗, when I believed you should only have one question word (in this case, 吗 should not be there in my opinion.)

Is this some kind of slang? Or just wrong?

Can it safely be disregarded?
The problem is not whether Chinese allows two question words in one sentence, it's that 什么 has multiple meanings.
It can variously mean any, anything, whatever. In the example &quot;你有什么安排吗&quot;, 什么 means &quot;any&quot;, as in &quot;Do you have any plans?&quot;
This is a very similar question to &quot;do you have plans?&quot;, which is what &quot;你有安排吗&quot; is.
By contrast, in the question &quot;你有什么安排?&quot;, 什么 is asking what, as in &quot;What plans do you have?&quot;
Here's some examples of when 什么 doesn't mean &quot;what&quot;:

只要认真学,什么都能学会 (as long as you study hard, you can learn anything)
他什么也不怕 (he's not afraid of anything)
他们到处放火，把什么都抢得精光。 (they set fires everywhere, and looted everything)
