Angry and a bit bewildered (4)
I believe the answer is:
wild
'angry' is the definition.
(I know that angry can be written as wild)
'a bit bewildered' is the wordplay.
'a bit' indicates a hidden word (the answer is formed by a bit of the clue).
'WILD' is hidden within 'bewildered'.
'and' acts as a link.
(Other definitions for wild that I've seen before include "Feral - crazy" , "Undomesticated" , "Not domesticated" , "Savage" , "Not tamed" .)
