Question: How do you pronounce the word "dour"?
I've read it and written it a lot but I've never said it and I don't think I've ever heard it. I know how I say it in my head -- I say it like "sour."
Would you be shocked to learn that the correct pronunciation is not "dow-er," rhyming with sour, but "dure," rhyming with "burr"? See the Cambridge dictionary, for example.
Now dictionary people are aware that people are saying it to rhyme with "sour" and are now providing that as a secondary pronunciation of the word, to match how people are actually saying it. Via Storied, with more mispronounced words.
