grill

I'm a little stuck... Click here to teach me more about this clue!

This might be a double definition.

'subject someone' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'heated questioning?' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.

'to' is the link.

Can you help me to learn more?

(Other definitions for grill that I've seen before include "Cook under a flame" , "Broil" , "Question hard" , "rack" , "Screen" .)
