Grandma - Zola novel (4)
I believe the answer is:
nana
I believe this clue is a double definition.
'grandma' is the first definition.
(I've seen this in another clue)
'zola novel' is the second definition.
(I've seen this in another clue)
(Other definitions for nana that I've seen before include "Relative" , "Grandma" , "Idiot" , "Old woman" , "Grandmother - dog in Peter Pan" .)
