Italian mount (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
etna
'italian mount' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for etna that I've seen before include "Impressive mount" , "Neat kind of European volcano" , "Active European volcano" , "Italian smoker" , "Highest peak in Italy south of the Alps" .)
