Consumer wanting their own point accepted by channel (8)
I believe the answer is:
cannibal
'consumer' is the definition.
(I have seen 'Fellow consumer' mean 'cannibal' so perhaps 'consumer' could also mean 'cannibal')
'own point accepted by channel' is the wordplay.
'own point' becomes 'nib' (I've seen this in another clue. I am not sure about the 'own' bit.).
'accepted by' indicates putting letters inside.
'channel' becomes 'canal' (synonyms).
'nib' placed inside 'canal' is 'CANNIBAL'.
'wanting their' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for cannibal that I've seen before include "One with odd eating habits" , "Animal that eats its own kind" , "One eats human flesh" , "Fellow consumer" , "Person who has someone for dinner?" .)
