Isle Dido madly loved (8)
I believe the answer is:
idolised
'loved' is the definition.
(I've seen this before)
'isle dido madly' is the wordplay.
'madly' indicates an anagram.
'isle'+'dido'='isledido'
'isledido' is an anagram of 'IDOLISED'.
(Other definitions for idolised that I've seen before include "Worshipped, say graven image" , "Hero-worshipped" , "Worshipped like graven image" , "put on a pedestal" , "Treated like a pop star" .)
