Having some friends for dinner? (11)
I believe the answer is:
cannibalism
'dinner?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cannibalism that I've seen before include "illegal consumption" , "Eating someone else" , "Like eating like" , "The eating of one's own species" , "The eating of fellow humans" .)
