In French, dejeuner, meaning literally breakfast, used to mean just that. But the nobility was used to getting up so late that dejeuner became lunch, diner became the evening meal, and they invented the 'petit dejeuner' to name the breakfast. In southern France and rural areas, dejeuner remained breakfast, dinner the mid-day meal, and souper the evening one. Miscommunication ensues :)

Yeah, and dinner being used for lunch while tea is used for dinner. Not confusing at all.

Being a Sri Lankan immigrant to Australia, I say dinner, lunch and breakfast. But I always was familar with tea being meal in England. I though it was something I got from my Noddy and William books. But actually, it might just have been an Australian thing that I was reading into othose books.

When I acutally went and lived in London, I learned that it was a northern thing. Which is odd, because in other ways Australia seems to be dominated by London culture. Or at least Australians talk like Londoners.

I don't think it has much to do with being a Londoner; I'm one too (native and resident), yet have used the "breakfast → dinner|lunch → tea" sequence my entire life.
