Departed after time (4)
I believe the answer is:
late
This clue is a double definition.
'departed' is the first definition.
(I've seen this before)
'after time' is the second definition.
(thesaurus)
(Other definitions for late that I've seen before include "Not yet arrived - departed" , "After the usual time" , "Passed on (but still not passed by!)" , "Still to come - already gone!" , "Recently dead" .)
