Helps beast run off (5)
I believe the answer is:
abets
'helps' is the definition.
(to abet is to aid or assist)
'beast run off' is the wordplay.
'beast' can be anagrammed to 'ABETS'.
Though, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for abets that I've seen before include "Assists in wrongdoing" , "Helps (someone to commit crime)" , "Assists dealer, say" , "Aids and encourages" , "Aids in wrong-doing" .)
