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 :)

In Québec and French Canada in general déjeuner/dîner/souper kept its original meaning too!

The word 'dîner' also meant breakfast!

Wiktionary says: dîner, From Old French disner, from Vulgar Latin *disiūnāre, from disieiūnāre, disjejūnāre (“to break the fast”)

People say “dejeuner” to mean breakfast a lot. But everyone knows that it is also not correct (we always this kind of people that will correct people on that)

But it is correct. The Parisian-imposed usage is obviously faulty :)

Well thing is, in Paris, you often skip the breakfast, so the real moment where you're breaking the fast is during lunch.

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

At least you know where you stand with supper, right?!

Yeah, and with breakfast, cause that's always in the morning ... like a nice afternoon wedding breakfast.

Well, that depends. In Scotland, "supper" generally means "with chips".

And which meaning of "chips"?

The Scottish one

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.
