<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">electrical interference</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 static that I've seen before include "Not active or moving" , "Stationary" , "Noise caused by electrical interferance" , "Lacking movement or action" , "irritation for the listener?" .)
