Procured leave on time (3)
I believe the answer is:
got
'procured' is the definition.
(I've seen this in another clue)
'leave on time' is the wordplay.
'leave' becomes 'go' (to go is to depart or leave).
'on' is a charade indicator (letters next to each other) (in a down clue, letters appear on others).
'time' becomes 't' (abbreviation).
'go'+'t'='GOT'
(Other definitions for got that I've seen before include "Landed" , "came by" , "Caught" , "Received; understood" , "Acquired" .)
