Seen in car; gent in angry state (9)
I believe the answer is:
argentina
'state' is the definition.
(Argentina is an example)
'seen in car gent in angry' is the wordplay.
'seen in' indicates the answer is hidden within the clue.
'ARGENTINA' is hidden within 'car gent in angry'.
(Other definitions for argentina that I've seen before include "state" , "Republic" , "Evita's country" , "Home of the tango" , "Evita's land" .)
