Object of excessive adoration (4)
I believe the answer is:
idol
'object of excessive adoration' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for idol that I've seen before include "Darling" , "Object of excessive love or devotion" , "'Worshipped object, admired person (4)'" , "Film star" , "Much-loved actor" .)
