This might be a double definition.

'pupil's' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?

'pet?' is the second definition.
The answer and definition can be both animals as well as being singular nouns.
Maybe there's an association between them I don't understand?

Can you help me to learn more?

(Other definitions for pup that I've seen before include "Young dog as palindrome" , "Whelp" , "Young of canines" , "Young animal" , "Youngster" .)
