Made beastly noise, tangled in hedge (7)
I believe the answer is:
neighed
'made beastly noise' is the definition.
(made a noise like a horse)
'tangled in hedge' is the wordplay.
'tangled' is an anagram indicator.
'in'+'hedge'='inhedge'
'inhedge' anagrammed gives 'NEIGHED'.
(Other definitions for neighed that I've seen before include "Whinnied" , "Cried" , "Made a sound like a horse" , "how Arab, for example, sounded" , "sounded "horsey"" .)
