<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">work for</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 serve that I've seen before include "Start a tennis match" , "Put the ball in play in 7 down" , "Wait at table" , "Answer the purpose" , "Minister to" .)
