I believe the answer is:
homer
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">bart's father</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 homer that I've seen before include "returning flier" , "pigeon, maybe" , "Trained pigeon" , "Great Greek who wrote The Iliad" , "The classical poet" .)
