<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">highlander perhaps</span>' is the definition.<br/ ><span class="explanation-format__explanation">(highlander is a kind of Scot)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for scot that I've seen before include "Highlander, say" , "One from northern UK" , "A Caledonian?" , "one from the North of Britain" , "Native of northern Great Britain" .)
