<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">little known</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for obscure that I've seen before include "Uncertain; indistinct" , "Like Jude, not well known" , "Indistinct or not well-known" , "Jude may be" , "Little-known" .)
