Remove some appointed officers (4)
I believe the answer is:
doff
'remove' is the definition.
(I've seen this before)
'some appointed officers' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'DOFF' is hidden within 'appointed officers'.
(Other definitions for doff that I've seen before include "Lift (one's hat)" , "Remove one's cap" , "Remove, hat say" , "Take off (clothing) - remove (hat)" , "Take off hat as mark of respect" .)
