Luxury material silver miners extract (6)
I believe the answer is:
ermine
'luxury material' is the definition.
The answer and definition can be both substances as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'silver miners extract' is the wordplay.
'ERMINE' is hidden within the letters.
But, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for ermine that I've seen before include "White fur from kind of 25 Across - judges may wear it" , "In mere strange fur" , "White fur worn by some judges" , "Regal fur" , "garb for nobility" .)
