Discharge, expel (5)
I believe the answer is:
eject
This clue is a double definition.
'discharge' is the first definition.
(I know that discharge can be written as eject)
'expel' is the second definition.
(I know that expel can be written as eject)
(Other definitions for eject that I've seen before include "Bail out" , "Video button" , "Force out violently" , "Evict" , "Deport" .)
