Is High Valyrian a Complete Language? 7 Best Facts
Ask “is High Valyrian a complete language?” and you will get two confident, opposite answers. Fans point to its full grammar and hold real conversations in it; skeptics point out that no one grew up speaking it and you cannot order a pizza in it. Both are right about the facts — they just mean different things by “complete.” Here is the honest, documented picture.
Quick Answer
High Valyrian is a fully functional constructed language: it has a complete, documented grammar (seven tenses, three moods, eight noun cases, four noun classes) and a growing lexicon of several thousand words documented on the wiki. But its vocabulary is far smaller than a natural language’s, it has no native speakers, and new words are still coined by its creator, David J. Peterson — so it is complete as a grammatical system, but still growing as a vocabulary.
Is High Valyrian a Complete Language? What “Complete” Means for a Conlang
When linguists judge whether a constructed language is complete, they usually ask three separate questions. First, is the grammar fully specified — can it express the same range of meanings a natural language can? Second, is the vocabulary large enough for real communication? Third, is there a community actually using it? A language can score full marks on the first while still growing on the second and third, and that is exactly where High Valyrian sits.
The background matters here. High Valyrian was created by linguist David J. Peterson for HBO’s Game of Thrones and later House of the Dragon. George R. R. Martin’s books contained only a handful of Valyrian words — Peterson built the grammar, the sounds, and most of the vocabulary from nearly nothing, the way he also built Dothraki for the same show. Unlike a natural language, which evolves over centuries of daily use, High Valyrian was designed, documented, and then extended on demand as scripts needed new lines. So when someone asks, “is High Valyrian a complete language?”, the honest answer depends on which of those three questions they actually mean.
What High Valyrian Has: A Full Grammatical System
On grammar, High Valyrian is genuinely complete — not a sketch, but a working system documented in a reference grammar on the language creator’s wiki. The inventory is richer than English in several dimensions — one more reason the question “is High Valyrian a complete language?” gets a firm yes on grammar:
- Verbs: seven tenses (present, aorist, future, imperfect, perfect, pluperfect, past habitual), three moods (indicative, subjunctive, imperative), two voices (active, passive), with agreement in person and number.
- Nouns: eight cases (nominative, accusative, genitive, dative, locative, instrumental, comitative, vocative), four classes (lunar, solar, terrestrial, aquatic), and four numbers (singular, plural, collective, paucal).
- Adjectives: full agreement in class, number, and case, plus four degrees of comparison — positive, comparative, superlative, and equative.
- Pronouns: personal, possessive, reflexive, and demonstrative forms, all inflected for case, covered in our High Valyrian pronouns guide.
- Word formation: documented derivational affixes (augmentatives, diminutives, negatives) and verbal applicative prefixes that reshape how arguments are encoded.
This is not a phrasebook with grammar taped on. It is a system in which you can build sentences Peterson never wrote — including subordinate clauses, questions (see our guide to High Valyrian question formation), and passives — and have them be grammatical or ungrammatical according to real rules. The High Valyrian grammar guide on this site summarizes the whole system for learners.
What It Lacks: Vocabulary Depth and Native Speakers
The honest limitation is the lexicon. The public dictionary documents several thousand words — enough for the world of the show (dragons, kings, oaths, war, family) and for a surprising range of everyday topics, but far short of a natural language’s hundreds of thousands of entries. Coverage of modern life is the thinnest part: there are no native words for computers, phones, airplanes, or pizza, because the language was never needed to describe them. This is the part of the “is High Valyrian a complete language?” question where the honest answer is “not yet, and maybe never fully.”
That gap is handled the way all young languages handle gaps: new words get coined. Peterson himself creates vocabulary as scripts and projects require it, and the documented lexicon on the wiki keeps growing as a result. Learners also coin or borrow terms for modern concepts, though strictly speaking only Peterson’s coinages are canonical. And there are no native speakers — nobody acquired High Valyrian as a first language in childhood. Everyone who speaks it learned it as a second language, which makes its speech community more like Esperanto’s than like French’s.
High Valyrian Compared to Other Languages
| Feature | High Valyrian | A natural language (e.g. English) | Esperanto (for scale) |
|---|---|---|---|
| Origin | Designed by David J. Peterson (2010s) for television | Evolved over centuries | Designed by L. L. Zamenhof (1887) |
| Native speakers | None | Millions to billions | A few thousand |
| Grammar | Fully documented; 7 tenses, 8 cases, 4 classes | Fully developed | Fully documented; simpler by design |
| Vocabulary | Several thousand words, still growing | Hundreds of thousands of words | Tens of thousands of words, 130+ years of growth |
| New words decided by | The creator, as needed | The speech community | The speech community, via usage |
| Learning resources | Wiki grammar, dictionaries, fan community | Abundant | Abundant |
For anyone weighing whether “is High Valyrian a complete language?” is a fair description, the comparison is flattering and sobering at once. Grammatically, High Valyrian stands beside any designed language as a finished system — it is more elaborately inflected than Esperanto by design, since it was built to sound ancient and regal rather than easy. Lexically, it is a young language, roughly where Esperanto was decades into its life rather than a century in. The trajectory is growth, not stagnation: every new season of television and every dictionary update adds documented words.
Can You Actually Have a Conversation in It?
Yes — within its vocabulary. Learners hold real conversations, write poetry and stories, and even translate texts into High Valyrian. The grammar gives you everything you need to express complex, nested, nuanced thoughts; the constraint is whether the words exist for your topic. Talk about loyalty, dragons, family, or travel and you will rarely grope for a word. Try to discuss software engineering and you will be coining terms within minutes.
That is the practical test behind the question “is High Valyrian a complete language?”, and High Valyrian passes it the way any second language with a few thousand words passes it: fluently inside its domain, creatively outside it. If you want to try the language hands-on, the English to Valyrian translator and Valyrian to English translator let you experiment with real sentences, the High Valyrian dictionary shows exactly how large the documented vocabulary is, and the High Valyrian phrases collection gives you conversation-ready material. One caveat worth remembering: no automatic translator produces perfect native-level grammar for a language this inflected — use them as learning aids, not oracles.

Frequently Asked Questions
Is High Valyrian a real language?
It is a real constructed language, not a natural one — and that is also the short answer to “is High Valyrian a complete language?”: complete as a grammatical system, still growing as a vocabulary. It has a complete documented grammar, a growing dictionary of several thousand words, and a community of speakers — but no native speakers, since it was designed by David J. Peterson for television rather than acquired by children.
Who created High Valyrian?
Linguist David J. Peterson created it for HBO’s Game of Thrones, and extended it for House of the Dragon. George R. R. Martin’s original books contained only a handful of Valyrian words; essentially the entire language — grammar, sounds, and vocabulary — is Peterson’s construction.
How many words does High Valyrian have?
Several thousand words are documented in the public dictionary on the wiki, and the number keeps growing as Peterson coins new vocabulary for new material. That is enough for fluent conversation inside its core domains, but far fewer than a natural language’s lexicon.
Can you become fluent in High Valyrian?
Yes, learners do. The grammar is fully learnable from the documented reference materials, and the vocabulary — while smaller than a natural language’s — supports real conversation, writing, and translation. Fluency means commanding the case system, verb conjugations, and several thousand words, which is comparable to reaching a solid intermediate level in a natural language.
Who decides new High Valyrian words?
David J. Peterson, the language’s creator, coins new words as scripts and projects require them, and they are documented on the wiki. Fans also coin or adapt terms for modern concepts, but only Peterson’s creations are canonical.
Is High Valyrian harder than Dothraki?
They were built by the same creator for the same show, but High Valyrian is the more elaborately inflected of the two — eight noun cases, four noun classes, and four grammatical numbers, versus Dothraki’s simpler system. Learners who master High Valyrian’s noun system usually find Dothraki straightforward by comparison.
So: is High Valyrian a complete language? As a grammatical system, unambiguously yes — it is one of the most thoroughly documented constructed languages in existence. As a vocabulary, it is complete enough to live in and still growing, with its creator adding words to this day. And as a living tongue, it is complete in the only way that matters: people use it to say things no one has ever said before.
