Looking to go over monarch's head? (7)
I believe the answer is:
peeking
'looking' is the definition.
(peeking is a kind of looking)
'go over monarch's head?' is the wordplay.
I cannot quite see how this works, but
'go' could be 'pee' (both can mean to urinate) and 'pee' is present in the answer.
'head?' could be 'king' and 'king' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for peeking that I've seen before include "ooking where one shouldn't" , "Looking slyly" .)
