What Language Do They Speak in House of the Dragon?
Discover the languages of House of the Dragon: High Valyrian, the Common Tongue, and how to understand them all.

What Language Do They Speak in House of the Dragon?
If you've watched House of the Dragon and found yourself wondering what language those characters are speaking when they're not using English, you're not alone. I had the same question during my first watch. Let me break down exactly what languages appear in the show and how to understand them. Try our free High Valyrian Translator to see how this ancient language works.
The Main Answer: High Valyrian and the Common Tongue
Here's the quick version: The special language you hear in House of the Dragon is High Valyrian, while most everyday conversations happen in English (which represents the "Common Tongue" in the show's world).
Here's a simple way to tell them apart: When characters speak with more elaborate intonation, rolling sounds, and the subtitles specifically label it as "High Valyrian," that's the special language. Regular English dialogue is the Common Tongue.
Here's a concrete example: When Rhaenyra and Prince Daemon discuss dragons, they often slip into High Valyrian. When they name dragons, they use High Valyrian entirely (like "Syrax," which comes from High Valyrian). This makes sense because the Valyrians were dragon masters, and High Valyrian serves as both the "noble language" and the "dragon communication language" in the show. Only Targaryens with Valyrian blood and a few close allies speak it.
Why High Valyrian? It's Not Just Random Gibberish
You might think the showrunners just made up some random sounds, but that's not true. Here's something most people don't know: High Valyrian is a fully constructed language system created by professional linguists. It has its own grammar, vocabulary, and pronunciation rules—it's not just random syllables.
I looked into this, and the linguist who designed it even published a book called "Living Language High Valyrian" that explains how to use the language. The showrunners did this for two reasons: First, to maintain consistency with Game of Thrones (since House of the Dragon is a prequel), and second, to highlight the Targaryens' uniqueness. They're not just regular nobles—they're "chosen ones" with Valyrian blood who can ride dragons.
Speaking High Valyrian shows their noble status and sets them apart from other houses. Personally, every time I hear characters speak High Valyrian, I immediately feel that "noble aura"—it's way more immersive than plain English dialogue.
Practical Tips: How to Follow the Story When High Valyrian Appears
This section solves a real problem: What do you do when High Valyrian dialogue appears and you miss the subtitles or can't hear clearly? Here are two tricks I've tested that help you catch every detail.
Tip 1: Turn on Bilingual Subtitles
No matter which platform you're using, you can find a "bilingual subtitles" option (Chinese + English or your preferred languages). Here's a key detail: When High Valyrian dialogue appears, the English subtitles give you the translation, and the Chinese subtitles match up. Many platforms also add a note like "(High Valyrian)" after these lines, so you know both the meaning and which language is being spoken.
I rewatched the entire series with bilingual subtitles, and not only did I catch everything, I also learned some common High Valyrian words. For example, the word for "dragon" is "drakarys" (you'll hear "Dracarys!" a lot in the show).
Tip 2: Pay Attention to Non-Verbal Cues
Often, even if you don't fully understand the High Valyrian dialogue, you can figure out what's happening from characters' expressions, gestures, and tone. When Rhaenyra speaks High Valyrian to her dragon, if her tone is firm and her eyes are sharp, she's probably commanding the dragon. If her tone is gentle, she's calming it down.
During my first watch, there was a scene where she and Daemon argued in High Valyrian. I missed the subtitles, but I could tell from their tone (getting more intense) and gestures (hand movements) that they were fighting about succession rights. I didn't lose track of the story at all.
Bonus: Other Languages in the Show
Besides the two main languages, the show also features some "minor languages," like Dothraki (the language of the horse lords from Game of Thrones) and Low Valyrian dialects from the Free Cities. These appear less often, mostly when foreign characters show up (like emissaries from the Free Cities).
Here's a quick way to tell them apart: Dothraki sounds rougher and more rhythmic, like a shout across the plains. Low Valyrian is a "simplified version" of High Valyrian—the pronunciation is flatter and less elaborate. You don't need to memorize these minor languages. Just know they're "foreign languages" representing different regions and peoples. They won't affect your understanding of the main plot.
I've been watching for a while, and I've never been confused by these minor languages. In fact, I think these details make the world feel more real and complete.
Understanding High Valyrian in Context
High Valyrian isn't just decoration—it's a storytelling tool. When characters switch to High Valyrian, it usually means something important is happening. They might be:
- Communicating with dragons
- Having private conversations they don't want others to understand
- Showing their noble status
- Discussing ancient Valyrian traditions
The more you watch, the more you'll notice these patterns. Use our High Valyrian Translator to practice recognizing and understanding these phrases in context.
The Bottom Line
House of the Dragon primarily uses two languages: High Valyrian (the ancient noble language of the Targaryens) and the Common Tongue (English). High Valyrian is a fully constructed language with real grammar and vocabulary, not random sounds. With bilingual subtitles and attention to context, you can follow every detail of the story, even when characters speak in High Valyrian.
