Husky-sounding Arab, possibly (5)
I believe the answer is:
horse
'arab possibly' is the definition.
(arab is a kind of horse)
'husky-sounding' is the wordplay.
'husky' becomes 'hoarse' ('hoarse' can be a synonym of 'husky').
'sounding' indicates a 'sounds like' (homophone) clue.
'hoarse' sounds like 'HORSE'.
(Other definitions for horse that I've seen before include "runner" , "Equid" , "Steed" , "drug?" , "Equine animal" .)
