Bachelor's last words left for hero (4)
I believe the answer is:
idol
'hero' is the definition.
(I've seen this before)
'bachelor's last words left' is the wordplay.
I cannot quite understand how this works, but
'left' could be 'l' (common abbreviation) and 'l' is located in the answer.
The remaining letters 'ido' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for idol that I've seen before include "Superstar; graven image" , "Blue-eyed boy" , "One much admired" , "Graven image or worshipped person" , "A graven image, or a hero" .)
