Dismissed when not at home? (3)
I believe the answer is:
out
I believe this clue is a double definition.
'dismissed' is the first definition.
(dismissed in cricket)
'not at home?' is the second definition.
(out can mean away from home)
'when' acts as a link.
(Other definitions for out that I've seen before include "Revealed; unconscious" , "what batsman doesn't want to be" , "In error" , "At fault - dismissed" , "in the shops" .)
