For how many parts is the house divided to? (the structure of this question)

Question

As a part of the English learning I am trying to build sentences - naturally, but sometimes I have a sentences that I'm not sure if they're correct and if a native English speaker would use them by himself or what is the better alternatives for them. One of those interrogative sentences that I build today is

For how many parts is the house divided to?

My doubts are: if it's correct to open a interrogative question with the prepositional "for", at least in this case. If it's correct to end with the preposition "to" in this case.

Answer 1

There are a couple of issues here. Let's break this down...

Is it correct to open a interrogative question with the prepositional "for"?

The answer in general is yes, that's fine. "For whom did you buy the flowers?" or "For how long did you live in Venice?" are perfectly normal. But...

Is it correct to open a interrogative question with the prepositional "for" in this case?

In this case, no. You divide something into parts, not for parts, or for to parts. So the correct phrasing would be "Into how many parts is the house divided?" Another, more conversational and less formal way to phrase it would be "How many parts is the house divided into?"
