<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">one of the ionian islands</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for corfu that I've seen before include "Ionian holiday island" , "Greek island, a British protectorate in C 19" , "One of the Ionian islands" , "Greeks here?" , "Major holiday island off west coast of Greece" .)
