Arrive to cover top of range with hard metal (6)
I believe the answer is:
chrome
'metal' is the definition.
(chrome is a kind of metal)
'arrive to cover top of range with hard' is the wordplay.
'arrive' becomes 'come' (coming is a kind of arriving).
'to cover' means one lot of letters goes inside another.
'top of range' becomes 'r' (I can't explain this - if you can you should believe this answer much more).
'with' says to put letters next to each other.
'hard' becomes 'h'.
'r' put after 'h' is 'hr'.
'come' placed around 'hr' is 'CHROME'.
Can you help me to learn more?
(Other definitions for chrome that I've seen before include "Metallic element" , "used to make plate" , "Protective finish on motor vehicle fittings" , "Brilliant finish" , "Deep yellow" .)
