Withdrawn copper distressed in heart of Nevada (9)
I believe the answer is:
evacuated
'withdrawn' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'copper distressed in heart of nevada' is the wordplay.
'copper' becomes 'cu' (chemical symbol).
'distressed' becomes 'ate' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in' indicates putting letters inside.
'heart of' means to look at the middle letters.
The central letters of 'nevada' are 'evad'.
'cu'+'ate'='cuate'
'cuate' going into 'evad' is 'EVACUATED'.
Can you help me to learn more?
(Other definitions for evacuated that I've seen before include "Left empty" , "abandoned" , "Cleared" .)
