I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">royal home</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for castle that I've seen before include "Fort" , "fortification" , "Stately home in Yorkshire" , "Rook, on chess board" , "Another word for chess rook" .)
