What the mineralogists are fighting over? (5,5)
I believe the answer is:
scrap metal
'what the' is the definition.
I can't tell whether this definition defines the answer.
'mineralogists are fighting over?' is the wordplay.
'mineralogists' becomes 'metal' (I can't justify this - if you can you should believe this answer much more).
'are fighting' becomes 'scrap'.
'over?' means one lot of letters go next to another (in a down clue, some letters go over others).
'metal' put after 'scrap' is 'SCRAP-METAL'.
Can you help me to learn more?
(Other definitions for scrap metal that I've seen before include "Waste material for remelting" , "it's unwanted by industry?" , "it's going to be melted down" , "reclaimed material" , "waste that's recyclable" .)
