<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sicilian volcano</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for etna that I've seen before include "Neat volcano overturned" , "Constant smoker" , "one blowing top?" , "Volcano in Sicily, quite neat" , "Volcano; reverse of stake" .)
