Isle I’d learn about (7)
I believe the answer is:
ireland
'isle' is the definition.
(Ireland is an example)
'i'd learn about' is the wordplay.
'about' indicates anagramming the letters.
'id'+'learn'='idlearn'
'idlearn' with letters rearranged gives 'IRELAND'.
(Other definitions for ireland that I've seen before include "music's John" , "The Emerald Isle" , "EU member country" , "State" , "Eire" .)
