<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">excessive</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know this)</span><br/ ><br/ >'<span class="explanation-format__original">inappropriate</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(similar in meaning)</span><br/ ><br/ ></span>
(Other definitions for undue that I've seen before include "Beyond normal limits" , "too much" , "More than appropriate" , "Excessive, disproportionate" , "Excessively, unreasonably" .)
