Form taken by some gold alloyed with tin? (5)
I believe the answer is:
ingot
'some gold alloyed with tin?' is the definition.
I can't tell whether this defines the answer.
'form taken by' is the wordplay.
'form' becomes 'in' (I can't justify this - if you can you should give a lot more credence to this answer).
'taken' becomes 'got' ('get' can be a synonym of 'take').
'by' is a charade indicator (letters next to each other).
'in'+'got'='INGOT'
Can you help me to learn more?
(Other definitions for ingot that I've seen before include "A lump of metal, perhaps gold" , "Mass of cast metal" , "this must be cast" , "Block of precious metal" , "Mass of precious metal" .)
