You've probably been mispronouncing He Who Must Not Be Named's name incorrectly all along.

On Tuesday, Harry Potter author J.K. Rowling confirmed that the T is silent in the moniker of the series' chief villain, Lord Voldemort. That's right - it's actually pronounced Vol-duh-MORE. How French.

We'll give you a few minutes to test that out and let your brain shift back into place.

The pronunciation is somewhat an open secret in the Harry Potter universe, with one random Twitter user pointing it out to another on Wednesday. Rowling responded to the tweet, confirming the correct usage, but also noted that "I'm pretty sure I'm the only person who pronounces it that way."

However, that's not actually the case. As another Twitter user was quick to point out, in the audio versions of the Harry Potter books, actor Jim Dale also leaves the T off at the end. But in the movie versions, "Voldemort" (as played by Ralph Fiennes) definitely has a hard T.
