Worker constantly striking (5)
I believe the answer is:
smith
This could be a double definition.
'worker' is the first definition.
(smith is a kind of worker)
'constantly striking' is the second definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
Can you help me to learn more?
(Other definitions for smith that I've seen before include "Worker in forge" , "Bessie - - , blues singer" , "Metal-worker" , "Worker in metals" , "Commonest name" .)
