Missed, neglected (10)
I believe the answer is:
overlooked
This clue is a double definition.
'missed' is the first definition.
('overlook' can be a synonym of 'miss')
'neglected' is the second definition.
('overlook' can be a synonym of 'neglect')
(Other definitions for overlooked that I've seen before include "allowed to go unpunished?" , "missed" , "Had in sight" , "Failed to notice" , "Neglected - visible from above" .)
