I believe the answer is:
finn
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">twain's huck</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 finn that I've seen before include "Huckleberry - -" , "Trollope's Phineas; one from Tampere" , "eg Sibelius" , "Nordic" , "Twain's Huck; Trollope's Phineas" .)
