<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">require</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >'<span class="explanation-format__original">necessitate</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that entail is a more specific form of the action necessitate)</span><br/ ><br/ ></span>
(Other definitions for entail that I've seen before include "Inevitably result in" , "Have as a logical consequence" , "Bring on, involve" , "Inalienable estate" , "Late in (anag.)" .)
