Song line (5)
I believe the answer is:
lyric
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">song line</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 lyric that I've seen before include "Airline" , "Of poetry that expresses the poet's feelings" , "Expressing poetical emotions" , "part of song" , "(Of poetry) expressing emotion" .)
