<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">room for children</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 nursery that I've seen before include "Place for baby human or baby plant" , "Place for young children or for rearing plants" , "to which children go" , "Child care centre" , "For young humans and young plants" .)
