Words with the prefix fore?
Foretell, foreword, forsight
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."

'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.
