Get over being angry (5)
I believe the answer is:
cross
This clue is a triple definition!
'get' is the first definition.
(thesaurus)
'over' is the second definition.
(thesaurus)
'being' acts as a link.
'angry' is the third definition.
(I've seen this before)
(Other definitions for cross that I've seen before include "Mongrel" , "Eg, saltire" , "Peeved" , "frustrated?" , "Mark; hybrid" .)
