<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">filled</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for full that I've seen before include "Containing as much as possible" , "and 18 Down: Accommodation and meals" , "Complete; replete" , "At capacity; rounded" , "Able to eat no more" .)
