Mile away from scurvy cure? (4)
I believe the answer is:
lime
'scurvy cure?' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'mile away' is the wordplay.
'away' indicates anagramming the letters (letters move away from their original places).
'mile' is an anagram of 'LIME'.
'from' is the link.
Can you help me to learn more?
(Other definitions for lime that I've seen before include "Tree, linden or citrus" , "white caustic earth" , "Caustic calcium" , "Having no money" , "alkaline" .)
