Style; behaviour (6)
I believe the answer is:
manner
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">style</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that style can be written as manner)</span><br/ ><br/ >'<span class="explanation-format__original">behaviour</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that manner is a type of behaviour)</span><br/ ><br/ ></span>
(Other definitions for manner that I've seen before include "Bearing - fashion" , "Fashion, way" , "Kind, sort" , "Mode" , "Way in which something is done" .)
