Blood surrounding head of goat in ravine (5)
I believe the answer is:
gorge
'ravine' is the definition.
(gorge is a kind of ravine)
'blood surrounding head of goat' is the wordplay.
'blood' becomes 'gore' ('gore' can be a synonym of 'blood'**).
'surrounding' indicates putting letters inside.
'head of' suggests taking the first letters.
The first letter of 'goat' is 'g'.
'gore' going around 'g' is 'GORGE'.
'in' is the link.
(Other definitions for gorge that I've seen before include "Devour" , "Steep narrow ravine" , "Steep raving (Cheddar)" , "Chasm; overeat" , "Swallow greedily" .)
