Sounded like an Arab, perhaps, heeding orders (7)
I believe the answer is:
neighed
'sounded like an arab' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
'heeding orders' is the wordplay.
'orders' indicates anagramming the letters.
'heeding' with letters rearranged gives 'NEIGHED'.
'perhaps' is the link.
Can you help me to learn more?
(Other definitions for neighed that I've seen before include "Cried" , "Heeding (anag)" , "Whinnied" , "Made a sound like a horse" , "how Arab, for example, sounded" .)
