<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">refer to indirectly</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for allude that I've seen before include "'Hint, suggest (6)'" , "Refer to, speak of" , "Refe" , "Speak about in passing" , "give a reference" .)
