<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">full up</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 sated that I've seen before include "given more than enough" , "Stuffed with food, too full" , "Stuffed, having had a surfeit" , "Fully satisfied" , "Stuffed with dates" .)
