Special event (8)
I believe the answer is:
occasion
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">special event</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for occasion that I've seen before include "Special or formal event" , "Special event or celebration" , "Time of (maybe special) event" , "A special event, or the time it happens" , "Special event; reason" .)
