<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">assistant to a parish priest</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for curate that I've seen before include "assistant barman in Ireland" , "Junior priest in a parish" , "Parish priest's assistant" , "Parson" , "A truce (anag)" .)
