My worst example was the word GIF pronounced like the peanut butter instead of properly as in Graphical. It’s worse because Amanda Montell was writing a linguistics book about the history of language and words.
Recent example was “eschew” which is pronounced Eh-shoo but the narrator said “Eskew” and it confused me so much I had to Google it to make sure I hadn’t been saying it wrong my whole life. What exmaples have you found?
My 6th grade teacher read us Harry Potter (the year it came out and long before the movies) and pronounced Hermione as Hermoyne. It wrecked me for a while because I read the next two books about Harry, Ron, and Hermoyne.
