Metal worker, not necessarily black (5)
I believe the answer is:
smith
This clue might be a double definition.
'metal worker' is the first definition.
(I've seen this in another clue)
'not necessarily black' is the second definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I can't see?
Can you help me to learn more?
(Other definitions for smith that I've seen before include "Common English surname" , "Metal-worker" , "Worker in metals" , "Adam, economist" , "Commonest name" .)
