Forage (8)
'forage' is the definition.
(I know that forage can be written as scrounge)
This is the entire clue.
(Other definitions for scrounge that I've seen before include "Cur's gone (anag) - beg" , "Try to get hold of" , "'Cadge, wheedle (8)'" , "Obtain (something) for free" , "Seek something free from others" .)
(Other definitions for scavenge that I've seen before include "Look for scrap" , "Feed on carrion or refuse" , "Pick up leavings" , "pick up something for nothing" , "Search for scraps" .)
