Devoured some game, ate no fish (5)
I believe the answer is:
eaten
'devoured' is the definition.
(similar in meaning)
'some game ate no fish' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'EATEN' is hidden within 'game ate no fish'.
(Other definitions for eaten that I've seen before include "Put away" , "worried" , "Devoured" , "demolished, possibly" , "used for food" .)
