Pottermore, the official authority on all things Harry Potter, released a list of Harry Potter terms people often pronounce incorrectly.
Well this one word has a lot of Harry Potter fans freaking out that they've been saying it wrong the WHOLE time!
When you read the books, like any English-speaking human, thought the word "Knuts" was pronounced "nut," with a silent "k."
You know, like knife, knock, knit....etc.
It's actually pronounced "ca-nut."
Here's what they said: "While we were running around saying ‘nuts’, Harry, Ron, Hermione and everyone else in the wizarding world were purchasing goods and services with Galleons, Sickles and ‘ca-nuts’."
Now you can school all of your Harry Potter friends who have been saying this word wrong!
