<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">positioned at intervals</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for spaced that I've seen before include "strung out" , "Separated by gaps" , "Placed at intervals" , "positioned at intervals" , "set some distance apart" .)
