General summary (8)
I believe the answer is:
overview
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">general summary</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 overview that I've seen before include "General summary of a subject" , "inspection" , "Broad perspective formed from above, general survey" .)
