Each ten devoured (5)
I believe the answer is:
eaten
'devoured' is the definition.
(similar in meaning)
'each ten' is the wordplay.
'each' becomes 'ea' (abbreviation).
'ea'+'ten'='EATEN'
(Other definitions for eaten that I've seen before include "What's taken in" , "Upset" , "Swallowed" , "Gobbled" , "having taken courses?" .)
