Workers here are constantly striking (5)
I believe the answer is:
anvil
'workers here are constantly striking' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for anvil that I've seen before include "Bone" , "Smithy's last" , "Block used in forge" , "Block for metalworking" , "Forging block" .)
