<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">marvels</span>' is the definition.<br/ ><span class="explanation-format__explanation">('wonder' can be a synonym of 'marvel')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for wonders that I've seen before include "Questions, marvels" , "Questons, marvels" , "Prodigies, miracles" , "Curiosities" , "Marvels - there used to be seven of them in the world" .)
