Hermione might have taught us how to say "Wingardium Leviosa," but her name used to be another story. J.K. Rowling most definitely helped us hardcore Harry Potter fans a bit in The Goblet Of Fire when Hermione taught foreigner Viktor Krum how to pronounce it phonetically. But until then, we had been saying it a thousand different ways.
Harry Potter fans took to Reddit to share the many ways they had been pronouncing her name back before Rowling cleared the air.
Sparkas: "I definitely read and pronounced the name as HER-MY-KNEE."
Jon_sparrow: "Read it as 'HERM - EE - OWN' for the first four books and yes, that does include the part where Hermione literally described to Krum the correct pronunciation."
Elbowsss: "I was beginning to think I was the only one. :) It was a HUGE relief to learn I had been pronouncing it wrong, because I always though that "Hermoine" sounds like some sort of uncomfortable medical affliction."
Haberdasheries: "My young brain didn't even bother trying to work it out logically so in my head she was 'harmonica.'"
SlouchyGuy: "No, I've read them in Russian and in official translation she was called Germiona :)"
Who else pronounced Hagrid as "Hay-grid" and Ginny as "Guinea?" I know it wasn't just me.
J.K. Rowling decided upon the name Hermione because she felt it was so unique and that there was a very tiny chance of girls who shared the moniker getting teased for it.
And in case you're wondering, it's Her-mi-o-ne. Get it right!
