Looks for (5)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">looks for</span>' is the definition.<br/ ><span class="explanation-format__explanation">(seek can mean to look for something)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for seeks that I've seen before include "Goes in pursuit" , "Hunts" , "Looks for" .)
