<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">poetic verse</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 stanza that I've seen before include "Group of lines in a poem, play, etc" , "Group of lines of verse" , "Lines forming a unit of verse" , "Verse of poem" , "Chunk of poetry" .)
