Transmute into silver? (6)
I believe the answer is:
change
This clue is a double definition.
'transmute' is the first definition.
(thesaurus)
'silver?' is the second definition.
(thesaurus)
'into' acts as a link.
(Other definitions for change that I've seen before include "Money returned as balance after purchase" , "we vary our routine for one" , "Alteration" , "Conversion" , "Cash" .)
