While Game of Thrones fans are busy poring over every still image and official trailer released for the show's final season in the hope of noticing some tiny detail that might hint at what's to come, David Peterson—the linguist who creates the series' fictional languages—dropped a huge piece of information: we've all been mispronouncing  Khaleesi.

While being interviewed for The Allusionist podcast, Peterson described the rampant mispronunciation as "a real thorn in my side." So just how should we be saying the Dothraki word?

"I wanted to make sure if something was spelled differently, it was pronounced differently," Peterson explained of his process of transforming the handful of Dothraki words George R.R. Martin had created into a full language. "That worked pretty well for everything except the word Khaleesi ... There's no way it should be pronounced 'ka-LEE-see' based on the spelling. So I had to decide, 'Am I going to respell this thing because I know how people are going to pronounce this, or am I going to honor that spelling and pronounce it differently?' I made the latter decision and I think it was the wrong decision."

(That said, in his book Living Language Dothraki, Peterson writes that "many Dothraki words have multiple pronunciation variants, often depending on whether the speaker is native or non-native. Khaleesi, for example, has three separate pronunciations: khal-eh-si, khal-ee-si, and kal-ee-si," which at a later point in the book spelled is "ka-lee-si.")

Given that Daenerys Targaryen has a mouthful of other titles at her disposal, we'll just call her the Mother of Dragons from now on.

Game of Thrones returns for its final season on April 14, 2019.
