Blush when injured by animal's horns? (5)
I believe the answer is:
gored
'injured by animal's horns?' is the definition.
Although both the answer and definition are past participle verbs, I can't see how one could define the other.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for gored that I've seen before include "Pierced by, eg, a bull's horn" , "Pierced - blush (can be 5 or 2,3)" , "Pierced with horn or tusk" , "Wounded by bull's horns" , "like an unfortunate matador?" .)
