<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">nosegays</span>' is the definition.<br/ ><span class="explanation-format__explanation">('posy' can be a synonym of 'nosegay')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for posies that I've seen before include "'Corsages, small bouquets (6)'" , "Sprays" , "Poises with bunches of flowers" , "Small bunches of flowers (a pocketful?)" , "Nosegays" .)
