One getting metal (6)
I believe the answer is:
copper
This clue could be a double definition.
'one getting' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'metal' is the second definition.
(I know that copper is a type of metal)
Can you help me to learn more?
(Other definitions for copper that I've seen before include "bluebottle" , "PC" , "detector?" , "Metal - washing-machine?" , "Reddish metallic element" .)
