Carefully observe confirmation of a palindrome? (3,2)
I believe the answer is:
eye up
'carefully observe' is the definition.
(to eye up is to scrutinise or look at)
'confirmation of a palindrome?' is the wordplay.
I cannot really see how this works, but
'palindrome?' could be 'eye' and 'eye' is present in the answer.
The remaining letters 'up' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
(Other definitions for eye up that I've seen before include "Eagerly watch" , "Check out" , "Look at (someone) appraisingly" , "Consider sexual attractiveness of (someone)" , "Examine closely" .)
