<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">word with friendly</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >'<span class="explanation-format__original">interface</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(user interface is a kind of interface)</span><br/ ><br/ ></span>
