Wow, people who dislike that video are strange. It's like whenever there's a really funny video, a few people do dislike it. So, did you know that Canda is the second largest country on earth?
That's really interesting, because Canada gets its name from when some explorers asked the natives what the place was called, and, thinking they were talking about the village, the natives said "Kanada", which meant "village".
I know it's probably a coincidence, but I find it sort of spooky.
I believe only countries in Europe and Asia or the 'Old World' have the -io- ending. The "New World" that includes The Americas, Africa (I think) and Oceania have the -o- ending. Due to different in usage by Esperantists.
"Canadian" is "Kanada". You just switch the noun suffix -o to the adjective suffix -a. In the New World, the people are named after their countries (e.g. Usona = US citizen, Usono = USA)
