Look embarrassed when wounded (5)
I believe the answer is:
gored
'wounded' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs can sometimes mean the same thing.
'look embarrassed' is the wordplay.
'look' becomes 'go' (I can't explain this - if you can you should believe this answer much more).
'embarrassed' becomes 'red' (someone may blush or go red when embarrassed).
'go'+'red'='GORED'
'when' acts as a link.
Can you help me to learn more?
(Other definitions for gored that I've seen before include "like an unfortunate matador?" , "Pierced - blush (can be 5 or 2,3)" , "Stabbed with a horn/tusk" , "Wounded by a bull" , "Injured by a horn or tusk" .)
