<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">work out a cryptogram</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for decode that I've seen before include "Get cracking" , "Convert a message into ordinary language" , "Interpret" , "Do translation" , "Explain" .)
