@Mitwah posted:I think it comes from the word "edge". For example, if I think I am faster that you in a foot race, I may give you an "adge" of about 3 to 10 yards in a 100 yard dash to the finish line. That is you will only need to run 97 to 90 yards. The less distance gives you an "adge' to win the race.
Those after school lessons can give you an adge to pass the exams with higher marks.
Not sure abt the lessons..
i rem it being used mostly for a race!!
