I believe the answer is:
genteel
<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">polite</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that polite can be written as genteel)</span><br/ ><br/ >'<span class="explanation-format__original">refined</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(similar in meaning)</span><br/ ><br/ ></span>
(Other definitions for genteel that I've seen before include "Courteous, well-bred" , "Suited to polite society" , "Well mannered" , "Exaggeratedly polite" , "Overly polite or refined" .)
