Close angrily (4)
I believe the answer is:
slam
'close angrily' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for slam that I've seen before include "Shut (a door) noisily" , "Shut loudly and forcibly" , "major contract" , "Shut violently" , "Close noisily" .)
