Peer at rich bloke's lover (8)
I believe the answer is:
nobleman
'peer' is the definition.
(I've seen this before)
'at rich bloke's lover' is the wordplay.
'at' says to put letters next to each other.
'rich bloke' becomes 'noble' (I can't explain this - if you can you should give a lot more credence to this answer).
'lover' becomes 'man' (male lover).
'noble' next to 'man' is 'NOBLEMAN'.
Can you help me to learn more?
(Other definitions for nobleman that I've seen before include "Male aristocrat" , "Titled person" , "I have a title" , "Member of the aristocracy" , "count, perhaps" .)
