Volcano appearing in street name (4)
I believe the answer is:
etna
'volcano' is the definition.
(Mount Etna)
'in street name' is the wordplay.
'in' indicates a hidden word.
'ETNA' can be found hidden inside 'street name'.
'appearing' is the link.
(Other definitions for etna that I've seen before include "burning mountain" , "Highest active volcano in Europe" , "Dangerous peak" , "Sicilian volcano" , "Volcano; reverse of stake" .)
