Sounded like a horse tangled in hedge (7)
I believe the answer is:
neighed
'sounded like a horse' is the definition.
I can't judge whether this defines the answer.
'tangled in hedge' is the wordplay.
'tangled' is an anagram indicator.
'in'+'hedge'='inhedge'
'inhedge' with letters rearranged gives 'NEIGHED'.
Can you help me to learn more?
(Other definitions for neighed that I've seen before include "Heeding (anag)" , "sounded "horsey"" , "how Arab, for example, sounded" , "Made a sound like a horse" , "Whinnied" .)
