Fairway alert (4)
I believe the answer is:
fore
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">fairway alert</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for fore that I've seen before include "Golfer's warning shout" , "Warning cry of golfer" , "A golfer's warning cry - ball in flight" , "The front part of a ship" , "Not aft" .)
