Make a break for it (4)
I believe the answer is:
bolt
'make a break for it' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bolt that I've seen before include "Run away; fasten (door)" , "Run away; bar of lock" , "Crossbow missile" , "eat food quickly and > lock up" , "playwright" .)
