The Nomai Language from Outer Wilds

The critically acclaimed indie game Outer Wilds by Mobius Digital isn’t just a game about space exploration—it’s a rich, atmospheric journey into ancient civilizations, time loops, and the fundamental mysteries of existence. One of the standout features of this narrative masterpiece is the enigmatic alien race known as the Nomai, and central to their worldbuilding is their beautifully imagined language.

In this three-part blog series, we’ll dive into the Nomai language—from its origins in the game’s lore to its structural design and cultural implications. Whether you’re a linguistics nerd, a Outer Wilds lore buff, or a game design enthusiast, there’s something fascinating here for you.

Who Were the Nomai?

Before we examine their language, it’s crucial to understand who the Nomai were. The Nomai are an ancient, long-extinct alien species that visited the solar system of the Outer Wilds long before the game’s protagonist is born. Their primary goal was to uncover the secrets of the universe, specifically to locate and study the elusive Eye of the Universe, a mysterious quantum object emitting a unique signal.

From their writings and ruins scattered across the solar system, we learn that the Nomai were scientists, philosophers, and explorers. Their civilization was deeply curious, methodical, and spiritual in a way that intertwined seamlessly with their science. And though they perished millennia ago, their legacy survives through their writings—the primary way players uncover the game’s complex, non-linear story.

First Contact: Reading Nomai Script in the Game

When players first encounter Nomai script, it immediately stands out from other fictional languages in video games. Unlike traditional text-based logs or journals, Nomai writing appears as spiraling threads of text etched into walls, devices, and ruins.

Each conversation typically begins with a central stem, followed by multiple branching threads—color-coded and curling like vines. These spirals represent multi-part conversations between different Nomai, often between members of the same team or family unit. The visual layout of their writing is intentionally non-linear, which mirrors the player’s own experience of uncovering the Outer Wilds story: piece by piece, thread by thread.

This was a bold design decision by the developers. By presenting text in a radial, branching structure, they emphasize the Nomai’s collaborative, egalitarian communication style, where conversations aren’t one-directional or hierarchical. It’s also a visual representation of discussion, not just documentation.

A Constructed Language for a Constructed Species

The Nomai language isn’t just gibberish with English subtitles. It was crafted as a constructed language (conlang)—a term popularized by communities that create entire fictional languages for media or personal use, such as Klingon (Star Trek), Dothraki (Game of Thrones), or Quenya (Lord of the Rings).

Although the Outer Wilds devs haven’t released a full Nomai dictionary or grammar, we can analyze several linguistic features based on the in-game translations and presentation:

1. Cultural Formality and Precision

Nomai sentences are often clear, structured, and formal. There’s little ambiguity, and the tone leans heavily into intellectual discourse. This aligns with their identity as scientists. For example:

“What happened to the vessel? Is it safe to assume it’s lost forever?”

“The Ash Twin project was never meant to be run this long.”

Such examples show a community with protocol, planning, and critical thought embedded in its communication.

2. Inquiry-Based Language

A recurring motif in Nomai writing is questioning. Many inscriptions begin with a query or hypothesis and develop as a back-and-forth among contributors. This pattern reinforces the Nomai’s inquisitive nature and their emphasis on peer-reviewed dialogue. Their language seems designed to support discovery through dialectic—not dogma.

3. Written-Only Preservation

It’s important to note that the Nomai language is only encountered in written form. Players never hear the Nomai speak, nor do they get phonetic renderings of Nomai speech. This may be due to the fact that their civilization is long extinct—or it could reflect an intentional design to give players a purely text-based, archaeological lens through which to experience their culture.

This lack of spoken representation creates a kind of linguistic archaeology—we, the players, become translators of an ancient text, slowly assembling the meaning and context of a culture that no longer exists.

Visual Language as Design

The Nomai’s spiral writing is more than just a cosmetic feature—it’s part of Outer Wilds‘ storytelling architecture. Each writing spiral is:

• Color-coded, showing which Nomai is speaking
• Visually organized, with threads clearly marked for reader flow
• Centrally anchored, always beginning with a primary thread

This isn’t just artistic flair. It suggests a species that values shared inquiry, with no dominant voice. The structure itself says: “Here is a starting idea. Add your thoughts, build on mine, diverge if needed.”

It’s not unlike a forum thread or Git commit history—each contribution is marked, visible, and contributes to a growing body of thought. The medium reinforces the message: the Nomai believe in transparent, collaborative progress.

Nomai Writing as a Gameplay Mechanic

In many games, reading alien scripts is optional or superficial. In Outer Wilds, reading Nomai script is essential to gameplay. You’re not just deciphering the lore—you’re solving puzzles, navigating time loops, unlocking projects, and piecing together existential revelations.

The game equips players with a Nomai translator tool, which automatically converts the spirals into readable English. But rather than making it feel mechanical or passive, the translator actually heightens the sense of wonder. You point it at a thread, wait a moment as the spiral unfolds, and then witness an ancient conversation resurrect itself before your eyes.

It’s a perfect metaphor for the entire game: unlocking a moment frozen in time, learning from it, and using that knowledge to inch closer to the truth.

Why the Nomai Language Resonates

What makes the Nomai language so compelling isn’t its complexity or realism (although it’s beautifully designed)—it’s the emotional weight it carries. You’re not just reading alien glyphs. You’re reading eulogies, debates, hopes, and final thoughts of beings who died in pursuit of something bigger than themselves.

Each time you uncover a new inscription, it’s like hearing a voice from a lost world.

And this, ultimately, is what makes the Nomai language so special: It is a bridge between the living and the dead, between the known and the unknown. It’s a language of discovery—and through it, we discover ourselves.

Theoretical Syntax and Structure

Although we only see the Nomai language in its translated form, the consistency of sentence structure and tone across different inscriptions suggests a standardized syntax. Let’s break down some recurring patterns and what they might tell us.

1. Sentence Construction: Declarative > Hypothetical > Reflective

Nomai inscriptions tend to follow a familiar rhythm: someone makes a statement, another Nomai offers a possibility, and a third may offer a reflection or conclusion. For example:

“The Eye’s signal has been detected again on Timber Hearth.”

“Could it be the Eye, or is it an echo from the previous cycle?”

“We must verify this with the Ash Twin project.”

This reveals a culture rooted in scientific dialogue, where knowledge is pursued through open questioning, not rigid hierarchy. Even when speaking of spiritual or metaphysical ideas (like the nature of the Eye), they retain a tone of inquiry rather than proclamation.

2. Limited Emotion, Abundant Respect

The Nomai rarely express emotion in direct terms, but they still show care and respect in how they respond to one another. The lack of overt sentimentality may reflect either a highly evolved communication standard or a practical focus on clarity. Still, there are moments—such as when referencing loved ones or those lost in accidents—where emotional subtext comes through subtly:

“Yarrow was my mentor. It pains me that we may never know her fate.”

This indicates that emotion is implied, not displayed, and that language may be a vehicle for preserving dignity more than personal catharsis.

Imagining Nomai Phonology: How Might It Sound?

Because we never hear the Nomai speak in the game, the phonological properties of their language remain entirely speculative. However, we can infer some possibilities based on the aesthetics of their written script and the culture they represent.

Possibility 1: Spiraling, Toned Cadence

Given the spiral structure of Nomai writing, some fans theorize that their spoken language might have been musical or tonal, perhaps with rising and falling intonations that echo the arcs of their written form. This would not be unprecedented—many human languages, such as Mandarin or Thai, use pitch to convey meaning.

Imagine Nomai dialogue resembling a harmonic exchange—like a conversation sung rather than spoken. It would suit their philosophical nature and reflect a harmonious way of thinking and speaking.

Possibility 2: Polyphonic or Multi-voiced Speech

The branching structure of their text also invites another wild possibility: multi-voiced communication. What if Nomai didn’t speak in strict turn-based sequences, but in overlapping threads—each voice contributing simultaneously, much like a round in choral music?

This could explain the unique layout of their writing, where different threads originate from a common stem. Each speaker could have added their voice concurrently, creating a woven tapestry of thoughts rather than a linear dialogue. While speculative, this idea reflects a culture more focused on collective synthesis than individual assertion.

Vocabulary Themes: Science, Mystery, and Ethics

Despite being a made-up language presented only through translation, the themes of vocabulary in Nomai inscriptions are remarkably consistent. From these patterns, we can draw insights into what their language was built to express.

Key Vocabulary Categories:

• Scientific Terms: Quantum, signal, phase, probe, black hole, time loop, harmonics.
• Philosophical Concepts: Possibility, perception, destiny, truth, understanding.
• Technical Terms: Warp core, power source, calibration, design module.
• Spiritual/Metaphysical Terms: The Eye, seeking, the universe, continuity, the cycle.

Their language reflects precision of thought paired with awe of the unknown. It is as equipped for building a machine as it is for contemplating the meaning of life.

And importantly, their writings reveal ethical language:

“If the Ash Twin project fails, we must accept that the Eye is not ours to find.”

“We are halting work on the cannon. The potential risk to Timber Hearth’s lifeforms is too great.”

This shows a linguistic and moral culture that weighs responsibility against discovery—a balance that feels refreshingly mature compared to the often conquest-driven narratives of fictional alien races.

Language as Cultural Legacy

Perhaps the most moving aspect of the Nomai language is what it ultimately becomes: a legacy tool. Long after their physical bodies are gone, their language is still functional, still communicating, still teaching.

In this way, the Nomai language is not just part of the game’s lore—it is a game mechanic for resurrection. Every time you translate a spiral, you resurrect a moment of their civilization. Their words persist without them, forming the true echo that the Eye of the Universe might have been calling.

Their language becomes:

• A trail of breadcrumbs for the player
• A memorial to those lost
• A map to deeper truth

Unlike many video game languages that exist for flair, the Nomai’s language is the game’s narrative architecture. Without it, there would be no Outer Wilds.

Final Thoughts: A Language of Seeking

The Nomai language is more than fictional glyphs on a cave wall. It is:

• A window into a lost civilization;
• A vehicle for collaborative knowledge;
• A tool for gameplay progression;
• And most of all, a language of seeking.

Seeking knowledge. Seeking connection. Seeking the Eye of the Universe—not to control it, but to understand it.

The Nomai believed that truth was worth any risk, and their language is the record of that belief. Through spirals and threads, loops and echoes, they created something that outlived them. Something that spoke not just to their kin, but to us—the players—centuries later.

In a game defined by cycles, it is fitting that the Nomai language also forms a kind of loop: a conversation continued not by its originators, but by those who find it and listen.

So the next time you aim your translator at a glowing spiral on a Nomai wall, take a moment to appreciate the layers of meaning it holds—not just as game design or fictional writing, but as a testament to the idea that language is memory, and memory is hope.
