Nominal issue, perhaps (5)
I believe the answer is:
susie
'nominal issue perhaps' is the definition.
I can't judge whether this defines the answer.
'issue perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'issue' with letters rearranged gives 'SUSIE'.
Can you help me to learn more?
(Other definitions for susie that I've seen before include "Woman" , "Little Susannah" , "Tongue-twister sister sewing shirts for soldiers" , "Wake Up Little - (Everly Brothers)" , "Old song: ''If you knew . . . . . like I know . . . . .''" .)
