Gent's weekend with Peer (4)
I believe the answer is:
look
'peer' is the definition.
(I know this)
'gent's weekend' is the wordplay.
'gent' becomes 'loo' (I can't explain this - if you can you should give a lot more credence to this answer).
'weekend' becomes 'k' (I've seen this in other clues).
'loo'+'k'='LOOK'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for look that I've seen before include "See - expression used to attract attention" , "Facial expression" , "Watch, observe" , "Peer" , "Search (with the eyes)" .)
