What's the difference between なんと and どう


I'm having a lot of trouble working out the difference between なんと and どう。 どう
is "How" e.g. これはどう書きますか "How do you write this?" and is easy for me to
understand. The problem is なんと、the dictionaries translate it as "how?" _and_
"what?".

If I want to say "how" when do I use どう and when do I use なんと and What's the
difference between これはなんと書きますか and これはどう書きますか。To put it in context, if it
helps, I'm studying JLPT2 but still have problems with this.




どう can be paraphrased as "in which way", "in what manner". なんと cannot, and it
means "as what".

> これはどう言いますか。  
>  (literally) ' **In what manner** do you say this?'  
>  'How do you pronounce this?'
>
> これは何と言いますか。  
>  (literally) ' **As what** do you say this?'  
>  'How do you call this?'
