Smith's of Mediterranean villas (5)
I believe the answer is:
anvil
'smith's' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'of mediterranean villas' is the wordplay.
'of' says the answer is hidden in the clue.
'ANVIL' is hidden within 'mediterranean villas'.
Can you help me to learn more?
(Other definitions for anvil that I've seen before include "Block used in forge" , "Forging block" , "One getting hammered regularly" , "One frequently gets hammered" , "Block on which metal can be hammered" .)
