Forename for father fox (7)
I believe the answer is:
patrick
'forename' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I can't see?
'father fox' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'fox' becomes 'trick' (synonyms).
'pa'+'trick'='PATRICK'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for patrick that I've seen before include "Patron saint who said 'Shoo!' to serpents" , "-- Moore, astronomer" , "Ireland's patron saint" , "Irish patron saint" , "Patron saint of Ireland" .)
