What to pay actors to emasculate (8)
I believe the answer is:
castrate
'to emasculate' is the definition.
('castrate' can be a synonym of 'emasculate')
'what to pay actors' is the wordplay.
I cannot quite understand how this works, but
'pay' could be 'rate' (I've seen this in other clues) and 'rate' is found within the answer.
'actors' could be 'cast' (group of actors) and 'cast' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for castrate that I've seen before include "To unman" , "Emasculate" .)
