<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">graduate</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that graduate can be written as alumnus)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for alumnus that I've seen before include "Former pupil or student" , "US college old boy" , "Former school pupil" , "Former college pupil" , "Past pupil" .)
