Spaniard with reason to reform (6)
I believe the answer is:
senora
'spaniard' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'reason to reform' is the wordplay.
'to reform' indicates an anagram (letters in a new form).
'reason' anagrammed gives 'SENORA'.
'with' is the link.
Can you help me to learn more?
(Other definitions for senora that I've seen before include "A married woman in Spain - stands to reason" , "Spanish title" , "Reason with Spanish Mrs" , "woman from Barcelona" , "Spanish lady within reason" .)
