Dilatory sort of hero-worship (8)
I believe the answer is:
idolatry
'worship' is the definition.
(I know that Idolatry is a type of worship)
'dilatory sort of' is the wordplay.
'sort of' indicates anagramming the letters.
'dilatory' anagrammed gives 'IDOLATRY'.
'hero' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for idolatry that I've seen before include "Worship of a false god" , "reverence" , "Adulation" , "Icon worship" , "Worship of godly images" .)
