Field runner in shock for commentator (4)
I believe the answer is:
hare
This might be a double definition.
'field runner' is the first definition.
'hare' can be an answer for 'runner' (fast-running animal). I am not sure about the 'field' bit.
'shock for commentator' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for hare that I've seen before include "'First catch your ....; then cook it'" , "Long-eared mammal" , "Fast runner" , "Mammal like a large rabbit" , "Rabbit-like creature" .)
