I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">college head</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for dean that I've seen before include "Kind of clergyman or university official" , "James ..., film actor" , "Church or college dignitary" , "FILMSTAR" , "Churchman" .)
