<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sheathe</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 encase that I've seen before include "Wrap" , "Cover completely" , "Frame" , "Enclose, cover" , "Cover with close-fitting surround" .)
