Most satisfactory setting for a wild creature (5)
I believe the answer is:
beast
'wild creature' is the definition.
(I've seen this before)
'most satisfactory setting for a' is the wordplay.
I cannot really see how this works, but
'satisfactory' could be 's' (abbreviation in education) and 's' is found within the answer.
'a' is within the answer.
The remaining letters 'bet' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for beast that I've seen before include "Wild animal" , "horse?" , "Traditional poet" , "Savage" , "Brute; creature" .)
