Ask out loud for something to eat (4)
I believe the answer is:
prey
'something to eat' is the definition.
'ask out loud' is the wordplay.
'ask' becomes 'pray' (I've seen this in another clue).
'out loud' shows a homophone (sound like).
'pray' is a homophone of 'PREY'.
'for' acts as a link.
(Other definitions for prey that I've seen before include "Animal hunted or caught for food" , "Animal sought as food" , "Animal's victim" , "Quarry, target" , "Predator's victim" .)
