Push off and break (5)
I believe the answer is:
leave
This clue is a double definition.
'push off' is the first definition.
(thesaurus)
'break' is the second definition.
(thesaurus)
'and' is the link.
(Other definitions for leave that I've seen before include "Withdraw - permission - to go - holiday" , "Don't touch" , "Insufficient foliage" , "Skip" , "Exit" .)
