Don't take a break (5)
I believe the answer is:
leave
I believe this clue is a double definition.
'don't take' is the first definition.
(I've seen this before)
'a break' is the second definition.
(I've seen this before)
(Other definitions for leave that I've seen before include "Depart, go" , "Depart - on authorised holidays?" , "Green light" , "Don't take - time off" , "Renounce" .)
