Introduction
Na'vi is the constructed language of the Na'vi people in James Cameron's Avatar film series. Linguist Paul Frommer (USC) created the language, commissioned by Cameron in 2005. Type a message above and the tool looks up each English word in a Na'vi vocabulary dictionary, outputting the Na'vi equivalent. Toggle between English-to-Na'vi and Na'vi-to-English modes with one click. Unknown words pass through unchanged. All processing runs in your browser, so nothing leaves your device.
What this tool does
- Word-level translation between English and Na'vi using a dictionary of attested vocabulary from the Avatar films and Paul Frommer's blog.
- Bidirectional: switch between English-to-Na'vi and Na'vi-to-English modes with one click. The swap button reverses direction without retyping.
- Multi-word phrases like "ngaru tìtxan" (thank you) and "ash people" (Mangkwan) are matched before single words.
- The settings panel shows the full vocabulary table with a search filter. Type to narrow the list by Na'vi or English text.
- Unknown words pass through unchanged in both directions. Punctuation and whitespace are preserved. Apostrophes in Na'vi words are handled correctly.
- All translation runs client-side. No text is sent to any server.
How this tool works
The translator splits your input into tokens using a regex that separates letter sequences from non-letter characters. Na'vi words may contain apostrophes (glottal stops), so apostrophes are treated as word characters. Each word token is lowercased and looked up in a dictionary. In English-to-Na'vi mode, the dictionary maps English words like "hello" to "kaltxi" and "fire" to "txep". In Na'vi-to-English mode, the reverse lookup runs. Multi-word phrases are checked first, sorted by length descending. Words not found in the dictionary pass through unchanged. Non-word tokens (spaces, punctuation, line breaks) are preserved exactly. The mode setting syncs to a URL query parameter, so you can share a link that preserves your configuration.
How the Na'vi language works
Paul Frommer, a linguist at the University of Southern California, created Na'vi for Avatar) (2008, directed by James Cameron). According to the Wikipedia article on the Na'vi language, Cameron commissioned Frommer in 2005 to build a language that sounded alien but could be learned and performed by actors. Frommer designed Na'vi with a phonology that includes ejectives (px, tx, kx), glottal stops (apostrophes), and the vowel inventory a, ä, e, i, ì, o, u. The language has about 2,600+ words as of 2026.
Frommer maintains the language through his blog Na'viteri.org, where he publishes new vocabulary and grammar explanations. The fan community Kelutral maintains an ongoing dictionary and offers learning resources. Na'vi has a dedicated learner community that has produced translations, original compositions, and conversation guides.
The third Avatar film, Avatar: Fire and Ash, is scheduled for release in December 2025. The film introduces the Ash People (Mangkwan), a Na'vi clan led by Varang. Frommer developed new vocabulary for the film, including txep (fire), txeva (ash), and Tlalim (the Windtraders, another new clan). The Wikipedia article on Avatar: Fire and Ash notes that the film explores Na'vi clans with different cultural practices, which required dialectal variation in the language. Frommer adjusted stress patterns and introduced clan-specific terms to reflect these differences.

Real-world examples
Translating a greeting
A user types "hello" in English-to-Na'vi mode. The tool looks up "hello" and finds "kaltxi". The output reads "kaltxi". If the user types "hello friend", the tool finds "kaltxi" for "hello" and "txeylan" for "best friend", producing "kaltxi txeylan". Words not in the dictionary pass through unchanged.
Translating fire and ash
Someone wants to write about the Ash People from Avatar: Fire and Ash. They type "fire ash" in the input. The dictionary looks up "fire" and returns "txep", then "ash" and returns "txeva". The output reads "txep txeva". These words were introduced by Paul Frommer for the third film and are documented on his blog Na'viteri.org.
Decoding Na'vi dialogue
A fan has a line of Na'vi from the films: "kaltxi nga". They paste it into Na'vi-to-English mode. The tool looks up "kaltxi" and finds "hello", then "nga" and finds "you". The output reads "hello you". Words not in the dictionary pass through unchanged so the reader can identify them manually.
Comparison with similar methods
| Method | Complexity | Typical use |
|---|---|---|
| Na'vi (word-level) | Medium | Avatar fan writing, roleplay, language learning |
| Minionese (word-level) | Low | Despicable Me fan writing, social media posts |
| Simlish (word-level) | Low | The Sims fan content, decorative text |
| Aurebesh | Low | Star Wars letter substitution, one glyph per letter |
Limitations or considerations
This tool performs word-level dictionary lookup, not full grammatical translation. Na'vi has a complete grammar designed by Paul Frommer, including case markers, verb infixes, and a free word order. This tool does not model any of that. The vocabulary covers attested words from the Avatar films and Frommer's blog, roughly 50 entries. Words outside the dictionary pass through unchanged. This is not encryption. For actual encryption, use the AES block cipher. For other fictional languages, try the Minionese translator, the Simlish translator, the Aurebesh translator, or the Standard Galactic Alphabet.
Frequently asked questions
Who created the Na'vi language?
Paul Frommer, a linguist at the University of Southern California, created Na'vi for Avatar (2008). James Cameron commissioned him in 2005 to build a language that sounded alien but could be learned and performed by actors. Frommer designed Na'vi with ejectives, glottal stops, and a unique vowel inventory. He maintains the language through his blog Na'viteri.org, where he publishes new vocabulary and grammar explanations.
Does this tool translate full Na'vi sentences?
No. This tool performs word-level dictionary lookup. It matches each English word to its Na'vi equivalent from a fixed vocabulary list. Na'vi has a complete grammar with case markers, verb infixes, and free word order, none of which this tool models. The tool does not handle Na'vi morphology or syntax. It is a vocabulary reference, not a full machine translation system.
How many words are in the Na'vi language?
Na'vi has about 2,600+ words as of 2026. Paul Frommer continues to expand the vocabulary through his blog Na'viteri.org. The fan community Kelutral maintains an ongoing dictionary with additional entries and usage examples. This tool's dictionary covers roughly 50 of the most frequently attested words from the Avatar films and Frommer's blog, including new vocabulary from Avatar: Fire and Ash.
What new words were added for Avatar: Fire and Ash?
Avatar: Fire and Ash (December 2025) introduces the Ash People (Mangkwan), a Na'vi clan led by Varang. Paul Frommer developed new vocabulary for the film, including txep (fire), txeva (ash), and Tlalim (the Windtraders, another new clan). The film explores Na'vi clans with different cultural practices, which required dialectal variation. Frommer adjusted stress patterns and introduced clan-specific terms.
Is Na'vi a real language?
Na'vi is a constructed language (conlang) created for a film franchise. It has real grammar and vocabulary designed by a professional linguist, and it has a dedicated learner community. Unlike Minionese or Simlish, which are improvised performance vocabularies, Na'vi was designed from the start as a complete language with phonology, morphology, and syntax. It is not a natural language, but it is more fully developed than most fictional languages.
Conclusion
The Na'vi translator converts English text to and from the constructed language Paul Frommer created for the Avatar film series. Type your message, switch modes with one click, and copy the output.
