Metal nuts gent has to turn (8)
I believe the answer is:
tungsten
'metal' is the definition.
(I know that tungsten is a type of metal)
'nuts gent has to turn' is the wordplay.
'nuts gent' anagrams to 'TUNGSTEN'.
However, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for tungsten that I've seen before include "Wolfram" , "Very hard metal, used in light bulbs" , "Metallic element in a strangely snug tent" , "Hard malleable metal" , "Rare metallic element" .)
