Dicky O'Neill's forename (6)
I believe the answer is:
lionel
'forename' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'dicky o'neill's' is the wordplay.
'dicky' indicates an anagram (dicky can mean not functioning properly).
'oneill' anagrammed gives 'LIONEL'.
Can you help me to learn more?
(Other definitions for lionel that I've seen before include "- Bart, (Oliver!)" , "Guy" , "Boy" , "Oil Len badly for another man" , "Blair possibly" .)
