<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">zimbabwe formerly</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 rhodesia that I've seen before include "Former British colony in central Africa" , "former state" , "Salisbury was its capital" , "Name of old Commonwealth country" , "What became Zimbabwe" .)
