Perhaps runner beside winding road could be animal killer (7)
I believe the answer is:
matador
'killer' is the definition.
(I've seen this before)
'perhaps runner beside winding road could be animal' is the wordplay.
I cannot really see how this works, but
'runner' could be 'r' (abbreviation) and 'r' is found within the answer.
'beside' could be 'at' and 'at' is found within the answer.
'road' could be 'm' and 'm' is found within the answer.
The remaining letters 'ado' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for matador that I've seen before include "he aims to get a bull" , "who does for bulls" , "ROM data (anag)" , "A bull-fighter.11 Beginning to develop" , "Spanish killer" .)
