Also, it's pronounced bill'-yard, not bill-lard.
So, where did the name "Billiard" come from? I haven't been able to find a definitive answer. The best explanation I have heard so far was that at the time the shape was named, the game was very popular, so whoever came up with the name for the pipe shape named it after the popular game of the day. Maybe. Good thing the popular game wasn't craps.
OK, regional differences. Where do you live?Mmm, nope. The first half of the word sounds exactly the same as the name "Billy."
Take "Billy Ardvark" and cut the "vark" off (same as Bigpond).
