Rude way to ask for a repeat (4)
I believe the answer is:
what
'ask for a repeat' is the definition.
I can't judge whether this definition defines the answer.
'rude way' is the wordplay.
I cannot really see how this works, but
'way' could be 'w' (Compass direction - West) and 'w' is present in the answer.
The remaining letters 'hat' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for what that I've seen before include "Which thing?" , "I beg your pardon" , "Interrogatory word" , "Eh?" , "I didn't hear" .)
