Adored by fans, I did lose out (8)
I believe the answer is:
idolised
'adored' is the definition.
(I know that adored can be written as idolised)
'i did lose out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'did'+'lose'='didlose'
'didlose' is an anagram of 'dolised'.
'i'+'dolised'='IDOLISED'
'by fans' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for idolised that I've seen before include "Worshipped like graven image" , "Worshipped, say graven image" , "Treated like a pop star" , "Revered, greatly loved" , "Hero-worshipped" .)
