<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">welcome site</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 mat that I've seen before include "To wipe your feet on" , "Thick flat pad on the floor" , "Paint with a dull surface" , "Tangle" , "Small carpet" .)
