I believe the answer is:
els
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">local borders?</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 els that I've seen before include "Golfer; elevated railways" , "US urban railways" , "Successful owner of several clubs" , "South African golfer" , "Ernie - - (golfer)" .)
