Look embarrassed when caught by the bull? (5)
I believe the answer is:
gored
'bull?' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs can occasionally mean the same thing.
'look embarrassed when caught by' is the wordplay.
'look embarrassed' becomes 'red' (red can mean to go red from embarrassment).
'when caught' becomes 'go' (I can't justify this - if you can you should believe this answer much more).
'by' means one lot of letters go next to another.
'red' put after 'go' is 'GORED'.
'the' is the link.
Can you help me to learn more?
(Other definitions for gored that I've seen before include "Pierced - blush (can be 5 or 2,3)" , "Wounded by bull's horns" , "Pierced by bull's horns" , "Pierced with horn or tusk" , "transfixed" .)
