Animal hit with anger, almost (5)
I believe the answer is:
tapir
'animal' is the definition.
(tapir is a type of animal)
'hit with anger almost' is the wordplay.
'hit' becomes 'tap' (I've seen this in other clues).
'with' is a charade indicator (letters next to each other).
'anger' becomes 'ire' (ire is intense rage).
'almost' means to remove the last letter (most of the word but not all of it).
'ire' with its last letter taken off is 'ir'.
'tap'+'ir'='TAPIR'
(Other definitions for tapir that I've seen before include "Animal with elongated snout" , "Long-nosed, hoofed mammal" , "I part with the pig-like animal" , "Browser" , "Nocturnal mammal with a short flexible proboscis" .)
