This just reminded me of the joke from HIMYM: Marshall: Whats that? Ted: A 1986 world book encyclopædia. Just the one I grew up with. Marshall: An encyclopædia? Ted: [laughing] Oh! You think it should be pronounced encyclo-pee-dia. I'ts a common mistake. But if you look at that squished together "ae" symbol in this here encyclopædia, you'll learn that it's a ligature derived from the Anglo-Saxon rune ash... [shelf breaks and falls] Marshall: You know, you're gonna have to pædia for that.
