<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">viking</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for norseman that I've seen before include "A viking, perhaps" , "invader" , "Scandinavian" , "one attacking north-east?" .)
