Angry symbol (5)
I believe the answer is:
cross
I believe this is a double definition.
'angry' is the first definition.
(cross can mean annoyed or angry)
'symbol' is the second definition.
(I have seen 'Christian symbol' mean 'cross' so perhaps 'symbol' could also mean 'cross')
(Other definitions for cross that I've seen before include "Eg, saltire" , "Grouchy" , "severe trial" , "Bad-tempered" , "Mark; hybrid" .)
