Tear to pieces in wild (6)
I believe the answer is:
savage
This might be a double definition.
'tear to pieces' is the first definition.
'savage' can be an answer for 'tear' (thesaurus). I am not certain of the 'to pieces' bit.
'wild' is the second definition.
('savage' can be a synonym of 'wild')
'in' acts as a link.
Can you help me to learn more?
(Other definitions for savage that I've seen before include "Cruel; wild" , "Viciously criticise" , "Brutal" , "Barbarian" , "poet who escaped death penalty" .)
