Put out or expel (5)
I believe the answer is:
eject
This clue is a double definition.
'put out' is the first definition.
(I've seen this before)
'expel' is the second definition.
(I know that expel can be written as eject)
(Other definitions for eject that I've seen before include "DVD player button" , "Spit out" , "Send out forcibly" , "Evict" , "Discharge; evacuate" .)
