Golfer's warning (4)
I believe the answer is:
fore
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">golfer's warning</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for fore that I've seen before include "At the bow" , "Fairway warning" , "Ancestor" , "A golfer's warning cry - ball in flight" , "Placed in front" .)
