I believe the answer is:
west
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sunset direction</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 west that I've seen before include "One Direction" , "Dog (from Argyll?)" , "Colombian with brews (anag)" , "The cardinal compass point of 270 degrees" , "'Go ___ , young man'" .)
