Black and blue and very angry (5)
I believe the answer is:
livid
This clue is a double definition.
'black and blue' is the first definition.
(I've seen this before)
'very angry' is the second definition.
(I've seen this before)
'and' is the link.
(Other definitions for livid that I've seen before include "Fuming" , "Angry; marked with bruise" , "in a paddy" , "... annoyed" , "Furious (informal)" .)
