Someone loved doing nothing when told (4)
I believe the answer is:
idol
'someone' is the definition.
(idol is a kind of someone)
'doing nothing when told' is the wordplay.
'doing nothing' becomes 'idle' (I've seen this before).
'when told' indicates a 'sounds like' (homophone) clue.
'idle' is a homophone of 'IDOL'.
'loved' is the link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for idol that I've seen before include "Sacred image" , "Graven image or greatly admired person" , "Blue-eyed boy" , "someone admirable" , "'Worshipped object, admired person (4)'" .)
