Leaves, departs (4)
I believe the answer is:
goes
I believe this is a double definition.
'leaves' is the first definition.
(I've seen this before)
'departs' is the second definition.
('go' can be a synonym of 'depart')
(Other definitions for goes that I've seen before include "Moves" , "Functions" , "SECOND PART OF 21" , "Departs; operates" , "Travels; attempts" .)
