Monkey bars cut down, abuse received (6)
I believe the answer is:
baboon
'monkey' is the definition.
(baboon is a kind of monkey)
'bars cut down abuse received' is the wordplay.
'bars' becomes 'bans' (ban can mean to bar or forbid).
'cut down' means to remove the last letter.
'abuse' becomes 'boo' (I can't explain this - if you can you should believe this answer much more).
'received' is an insertion indicator.
'bans' with its last letter taken off is 'ban'.
'ban' enclosing 'boo' is 'BABOON'.
Can you help me to learn more?
(Other definitions for baboon that I've seen before include "Large long-nosed Arabian or African monkey" , "Large primate" , "animal" , "clumsy uncouth person" , "Stupid person" .)
