Some comprehend editor's wound up (5)
I believe the answer is:
ended
'wound up' is the definition.
(how things 'wind up' is how they end)
'some comprehend editor's' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ENDED' is hidden within 'comprehend editors'.
(Other definitions for ended that I've seen before include "Stopped" , "died" , "Concluded" , "Finished, terminated" , "Broke off; finished" .)
