Block pagan villagers going round (5)
I believe the answer is:
anvil
'block' is the definition.
(I know that anvil is a type of block)
'pagan villagers going round' is the wordplay.
'going round' says the answer is hidden in the clue.
'ANVIL' is hidden in the letters of 'pagan villagers'.
(Other definitions for anvil that I've seen before include "Forging equipment" , "Metalworker's block" , "A blacksmith's iron block" , "On which hot metal is shaped" , "Block in smithy" .)
