<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">german capital</span>' is the definition.<br/ ><span class="explanation-format__explanation">(capital of Germany)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for berlin that I've seen before include "A once-divided city" , "Irving -, Russian-born musical composer" , "Composer < in carriage < in European capital" , "German capital" , "Capital of Germany" .)
