Stop soprano getting enthralled by crazy diets (6)
I believe the answer is:
desist
'stop' is the definition.
(desist means to stop)
'soprano getting enthralled by crazy diets' is the wordplay.
'soprano getting' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'enthralled by' indicates putting letters inside ('enthral' can mean 'capture').
'crazy' indicates anagramming the letters.
'diets' is an anagram of 'desit'.
's' put within 'desit' is 'DESIST'.
Can you help me to learn more?
(Other definitions for desist that I've seen before include "Eject; annoyed" , "Stop, don't continue" , "Stop, abstain" , "'Refrain from, stop (6)'" , "Cease (from doing something)" .)
