registrar
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">hospital doctor</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 registrar that I've seen before include "Mid-ranking doctor" , "certifies births and deaths" , "clerk" , "Official recording births, deaths and marriages" , "Official record-keeper" .)
