Possibly banal name (5)
I believe the answer is:
alban
'name' is the definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?
'possibly banal' is the wordplay.
'possibly' is an anagram indicator.
'banal' anagrammed gives 'ALBAN'.
Can you help me to learn more?
(Other definitions for alban that I've seen before include "Saintly type" , "First English Christian martyr" , "First British martyr, supposedly born in Verulamium" , "First Christian martyr in England" , "early martyr" .)
