I believe the answer is:
erato
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">one of the muses</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for erato that I've seen before include "Greek muse of lyric and love poetry" , "Muse of 11 and 23" , "Poet's inspiration" , "Poet's muse" , "Who may have inspired poetry" .)
