<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">woman on her wedding day</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 bride that I've seen before include "She's just about to be married" , "presumably honeymoon for me?" , "Groom's partner" , "new union member" , "Wife of groom" .)
