Use of に in "What would you like to drink?"
The suggested translation for this sentence is
おのみものは 何に しますか。
The 何 kanji is always read "nani" by the app, so does this really require two "ni"s? And why?
Also, I'm having trouble with this sentence in general. Trying a literal translation, I come up with: "As for the honorable beverages, which do you make?"
What am I missing?
何 can also pronounced as なん in some cases. Here it is pronounced as なに. And yes you need to say 2 times Ni here なに に. However なん pronunciation is also acceptable in a more familiar context.
In here します does not mean To Do or To Make. It is part of an idiomic expression Sth. + に + します which means To Choose Sth.
I would like a coffee (I choose coffee)
I make coffee (I brew coffee)
