Where the Dons may be out to win! (7)
I believe the answer is:
swindon
'win' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I can't see?
'where the dons may be out' is the wordplay.
'where' becomes 'win' (I can't explain this - if you can you should believe this answer much more).
'may be' is an anagram indicator.
'out' indicates putting letters inside.
'dons' anagrammed gives 'sdon'.
'win' put within 'sdon' is 'SWINDON'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for swindon that I've seen before include "22 [WILTS] town" , "English town" , "Large Wiltshire railway town" .)
