Horrifying sprawled in his gore (7)
I believe the answer is:
ogreish
'horrifying sprawled in' is the definition.
The definition suggests an adjective which matches the answer.
'his gore' is the wordplay.
'his gore' anagrams to 'OGREISH'.
However, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for ogreish that I've seen before include "Ugly" , "Monstrous, misshapen, cruel" , "Fearsome" , "Like a cruel monster" , "Terrifyingly big" .)
