Grandmother makes bread (3)
I believe the answer is:
nan
I believe this clue is a double definition.
'grandmother' is the first definition.
(nan can informally mean a grandmother)
'bread' is the second definition.
(variant spelling of naan)
'makes' acts as a link.
(Other definitions for nan that I've seen before include "Indian bread - older relative" , "Indian bread; grandma" , "Elderly relative" , "woman from an earlier generation" , "type of slightly leavened bread" .)
