Copper in vain tortured Andean native (6)
I believe the answer is:
vicuna
'andean native' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'copper in vain tortured' is the wordplay.
'copper' becomes 'Cu' (Cu is the chemical symbol for copper).
'in' indicates putting letters inside.
'tortured' indicates anagramming the letters.
'vain' is an anagram of 'vina'.
'cu' inserted inside 'vina' is 'VICUNA'.
Can you help me to learn more?
(Other definitions for vicuna that I've seen before include "woollen fabric" , "Small wildl cud-chewing Andean animal with soft wool" , "Wild relative of llama" , "fine wool cloth" .)
