Misinterpret natural elements in volcano (4)
I believe the answer is:
etna
'volcano' is the definition.
(Etna is an example)
'misinterpret natural elements in' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ETNA' is hidden within 'misinterpret natural elements'.
(Other definitions for etna that I've seen before include "Sicily's 15" , "Impressive mount" , "Italian volcano" , "one blowing top?" , "Long-term smoker" .)
