I believe the answer is:
snub
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">rebuff</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that rebuff can be written as snub)</span><br/ ><br/ >'<span class="explanation-format__original">spurn</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that snub is a more specific form of the action spurn)</span><br/ ><br/ ></span>
(Other definitions for snub that I've seen before include "Rebuff, spurn" , "Cut; ignore" , "Slight - short and blunt - humiliation" , "Ignore totally" , "Spurn; (of nose) turned up at the end" .)
