People-eaters (9)
I believe the answer is:
cannibals
I believe this is a double definition.
'people' is the first definition.
(cannibal is a kind of person)
'eaters' is the second definition.
(I have seen 'Eaters of humans ' mean 'cannibals' so perhaps 'eaters' could also mean 'cannibals')
(Other definitions for cannibals that I've seen before include "People who eat people" , "Eaters of humans" , "Human flesh eaters" , "Animals that eat their own kind" .)
