Anvil setting (3)
I believe the answer is:
ear
'anvil setting' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ear that I've seen before include "Corn seed-holder" , "'Give every man thine ..., but few thy voice' (Hamlet)" , "one hears" , "Organ inside heart" , "Aural appendage" .)
