Officially accepted works (5)
I believe the answer is:
canon
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">officially accepted works</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for canon that I've seen before include "Such literary works are genuine" , "minister?" , "Church decree or law" , "accepted criterion" , "collected works" .)
