Grandma's kind of bread (3)
I believe the answer is:
nan
This could be a double definition.
'grandma's' is the first definition.
(nan can informally mean a grandmother)
'kind of bread' is the second definition.
'nan' can be an answer for 'bread' (variant spelling of naan). I am not sure about the 'kind of' bit.
Can you help me to learn more?
(Other definitions for nan that I've seen before include "Elderly relative" , "Darling dog" , "Grandmother (colloq.)" , "Gran" , "Grannie" .)
