Maybe there's an association between them I don't understand?
'junior' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
Can you help me to learn more?
(Other definitions for pup that I've seen before include "Whelp" , "Youngster" , "Young of canines" , "Young dog as palindrome" , "Canine young" .)
