Canine chum? (3)
I believe the answer is:
pal
This clue might be a double definition.
'canine' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'chum?' is the second definition.
(both can mean a friend)
Can you help me to learn more?
(Other definitions for pal that I've seen before include "Mate, buddy" , "Brother" , "Crony" , "Mate, informal friend" , "Friend (colloq.)" .)
