Hope audibly for a quarry (4)
I believe the answer is:
prey
'quarry' is the definition.
(synonyms)
'hope audibly' is the wordplay.
'hope' becomes 'pray'.
'audibly' shows a homophone (sound like).
'pray' is a homophone of 'PREY'.
'for a' acts as a link.
(Other definitions for prey that I've seen before include "Animal hunted and killed for food" , "Animal hunted by another for food" , "Animal hunted or caught for food" , "Hunter's quarry" , "Quarry, fair game" .)
