Axiomatic, obvious (4-7)
I believe the answer is:
self-evident
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">axiomatic</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >'<span class="explanation-format__original">obvious</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ ></span>
(Other definitions for self-evident that I've seen before include "Not requiring further explanation" , "Needing no explanation" , "Not needing to be demonstrated" , "Not needing to be explained" , "Obvious" .)
