Poetry (5)
I believe the answer is:
verse
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">poetry</span>' is the definition.<br/ ><span class="explanation-format__explanation">(lines written in verse)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for verse that I've seen before include "Literature in metrical form" , "Poetry - subdivision of the Bible" , "Metrical text" , "Piece of poetry" , "literary offering" .)
