<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">less poor</span>' is the definition.<br/ ><span class="explanation-format__explanation">('rich' can be the opposite of 'poor' so perhaps 'richer' is reasonable for 'less poor')</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for richer that I've seen before include "More wealthy" , "More affluent" , "Wealthier" , "More well-off" , "Having more wealth" .)
