Onion on stick for monkey (11)
I believe the answer is:
rapscallion
'monkey' is the definition.
(I know that monkey can be written as rapscallion)
'onion on stick for' is the wordplay.
'onion' becomes 'scallion' (scallion is a kind of onion).
'on' says to put letters next to each other.
'stick for' becomes 'rap' (I can't justify this - if you can you should believe this answer much more).
'scallion' after 'rap' is 'RAPSCALLION'.
Can you help me to learn more?
(Other definitions for rapscallion that I've seen before include "Plain carols (anag) - rogue" , "mischief maker" , "Monkey" , "Disreputable person - local sprain (anag)" , "Scoundrel" .)
