<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">take five</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 rest that I've seen before include "'''God ... ye, merry gentlemen'' (carol) (4)'" , "Calm" , "Tranquillity" , "Remainder; be inactive" , "Repose, others" .)
