Is cruel to a wild beast (5)
I believe the answer is:
beats
'is cruel' is the definition.
I can't tell whether this definition defines the answer.
'wild beast' is the wordplay.
'wild' indicates an anagram.
'beast' is an anagram of 'BEATS'.
'to a' is the link.
Can you help me to learn more?
(Other definitions for beats that I've seen before include "Tans" , "Rhythms" , "Regular routes for policemen" , "Buffets" .)
