'Fore' is the word that is shouted. The definition of fore is 'located at or toward the front' and the term 'to the fore' means something that has moved into a position of importance. It would be safe to say that a struck golf ball that is moving towards someone is moving into a 'position of importance'. So 'FORE!' is shouted to alert the person that a ball is headed in their direction.
Golfers have to yell "FORE" to warn the people. Hope I helped. :)
FORE - Meaning lookout ahead
Years ago, when a player played golf, he had a caddy and the caddy had an assistant, the fore caddy. The fore caddy used to stand down the fairway and watch where the ball went, when the player hit, they used to shout 'fore' to let the fore caddy know the ball was coming. It is now a term used to let other players know that a ball may come near them.
"Fore" is another word for "ahead" (think of a ship's fore and aft). Yelling "fore" is simply a shorter way to yell "watch out ahead" (or "watch out before"). It allows golfers to be forewarned of an incoming ball, in other words.
It is "Fore", not "four", hence not "five" either. The "Fore" comes from the old use of "Fore-caddies" who were down the fairway looking for the golfers ball coming down the fairway from the tee. The golfer would yell "Fore" telling the "Fore-caddie" that the ball was on the way. Now, of course, "Fore" means "Watch out! Ball is coming your way."
You actually shout 'Fore'. It's to warn people in front of you.
golf The call is Fore! As in before, meaning in front, not four as in the number. It is a warning to those players ahead.
