Presupposes (7)
I believe the answer is:
assumes
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">presupposes</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for assumes that I've seen before include "Puts on; accepts" , "Takes for granted or puts on" , "Take to be the case" , "Takes to be the case" , "dons" .)
