What the horse did when one was thrown? (5)
I believe the answer is:
shied
'thrown?' is the definition.
(I've seen this before)
'what the horse did when one' is the wordplay.
I cannot quite see how this works, but
'horse' could be 'h' (synonyms) and 'h' is found within the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'was' is the link.
Can you help me to learn more?
(Other definitions for shied that I've seen before include "Flung, tossed" , "Cast" , "horse did this?" , "Jumped nervously; threw" , "Thrown" .)
