Rover's friend? (3)
I believe the answer is:
pal
This clue could be a double definition.
'rover's' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'friend?' is the second definition.
(pal can mean a friend)
Can you help me to learn more?
(Other definitions for pal that I've seen before include "Brother" , "Crony" , "Bud" , "Close friend" , "Buddy, chum" .)
