Devoured more than seven, reportedly (3)
I believe the answer is:
ate
'devoured' is the definition.
(to devour is to eat)
'more than seven reportedly' is the wordplay.
'more than seven' becomes 'eight'.
'reportedly' indicates a 'sounds like' (homophone) clue.
'eight' is a homophone of 'ATE'.
(Other definitions for ate that I've seen before include "upset > Greek goddess" , "Ingested" , "Munched" , "Had at meal" , "mischief-maker" .)
