German villain holds something for forging (5)
I believe the answer is:
anvil
'something for forging' is the definition.
(item in a blacksmith's forge)
'german villain holds' is the wordplay.
'holds' indicates a hidden word.
'ANVIL' is hidden within 'german villain'.
(Other definitions for anvil that I've seen before include "A blacksmith's iron block" , "Metalworker's block" , "It helps forger" , "Block on which metals are hammered" , "Alvin (anag.)" .)
