French: déjeuner

Self-tutoring about French: the tutor mentions a question.

I was taught, as a kid, that “déjeuner” means lunch, while “petit-déjeuner” means breakfast. However, whenever I mention “déjeuner” as lunch, I’m corrected: “Lunch is dîner,” I’m told. Who is right?

Well, apparently “déjeuner” was meant to mean breakfast, but the language evolved so that “déjeuner” means lunch, to a lot of people.
