Mina covered with cream is knock out! (9)
I believe the answer is:
eliminate
'knock out' is the definition.
(I've seen this in another clue)
'mina covered with cream' is the wordplay.
'covered with' indicates putting letters inside.
'cream' becomes 'elite' (as in the cream of the crop).
'mina' placed into 'elite' is 'ELIMINATE'.
'is' acts as a link.
(Other definitions for eliminate that I've seen before include "Knock out" , "Do away with, get rid of" , "put out" , "Eradicate" , "Do away with, remove" .)
