Beg audibly for quarry (4)
I believe the answer is:
prey
'for quarry' is the definition.
(synonyms)
'beg audibly' is the wordplay.
'beg' becomes 'pray' (synonyms).
'audibly' shows a homophone (sound like).
'pray' is a homophone of 'PREY'.
(Other definitions for prey that I've seen before include "Animal's victim" , "Animal hunted or caught for food" , "Animal sought as food" , "Quarry, target" , "Hunted creature" .)
