Forge is close to anvil, say (7)
I believe the answer is:
ossicle
'anvil say' is the definition.
(anvil is a kind of ossicle)
'forge is close' is the wordplay.
'forge' indicates anagramming the letters (I've seen 'forged' mean this).
'is'+'close'='isclose'
'isclose' is an anagram of 'OSSICLE'.
'to' is the link.
(Other definitions for ossicle that I've seen before include "A hammer" , "Very small bone, in the middle ear say" , "Small bone, especially one in the middle ear" .)
