New author expected to reveal some mine winnings (3)
I believe the answer is:
ore
'some mine winnings' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'new author expected to reveal' is the wordplay.
'to reveal' says the answer is hidden in the clue.
'ORE' is hidden within 'new author expected'.
Can you help me to learn more?
(Other definitions for ore that I've seen before include "Deposit of mine" , "Material for smelting" , "tangle" , "Valuable resource" , "Mineral containing valuable metal" .)
