ought to

[Samia Khalaf]

Can we use ought to in WH questions? For example, what is the WH question in this case?
He ought to do the food shopping.
Why.............................?
Thanks

Opinions differ on this.

While many people would say 'did he ought to', some feel that the question form is 'ought he to'.

In your case, the easy solution is to say just, "Why?"
