Volcanic region around Etna hot and saline (5,6)
I believe the answer is:
saint helena
'volcanic region' is the definition.
The definition suggests a singular noun which matches the answer.
'around etna hot and saline' is the wordplay.
'around' indicates an anagram.
'hot' becomes 'h' (abbreviation eg on taps).
'and' means one lot of letters go next to another.
'etna'+'h'='etnah'
'etnah' after 'saline' is 'salineetnah'.
'salineetnah' anagrammed gives 'SAINT HELENA'.
Can you help me to learn more?
(Other definitions for saint helena that I've seen before include "place for Emperor" , "British S. Atlantic colony" , "Where Napoleon died" , "British South Atlantic island" .)
