I believe the answer is:
apply
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">have relevance</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 apply that I've seen before include "Agree" , "Use - ask (for)" , "Put to use" , "Put in for job" , "Ask for, a position perhaps" .)
