<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">royal personage</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 prince that I've seen before include "Senior male member of a royal family after the sovereign" , "Son of a royal house" , "Son of a sovereign" , "Royal personage" , "King's son" .)
