Monkey putting vegetables in still (7)
I believe the answer is:
appease
'still' is the definition.
(appeasing is a kind of stilling)
'monkey putting vegetables in' is the wordplay.
'monkey' becomes 'ape' (I've seen this before).
'putting vegetables' becomes 'peas' (I am not sure about this - if you are sure you should believe this answer much more).
'in' indicates putting letters inside.
'ape' enclosing 'peas' is 'APPEASE'.
Can you help me to learn more?
(Other definitions for appease that I've seen before include "Placate by making concessions" , "To behave like Chamberlain" , "Make peace with" , "Mollify, placate" , "Quiet" .)
