Rediscovered ducal name (5)
I believe the answer is:
claud
'name' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I can't see?
'rediscovered ducal' is the wordplay.
'ducal' anagrams to 'CLAUD'.
But, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for claud that I've seen before include "Man" , "Boy" .)
