Wife of Siva (4)
I believe the answer is:
kali
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">wife of siva</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that Kali is married to Shiva)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for kali that I've seen before include "Hindu goddess of death" , "Hindu goddess of destruction" , "Terrifying Hindu goddess" , "Indian goddess" , "Hindu consort of Siva" .)
