How I do culture-first conlangs for my worlds.

Here it is: anyone can smash random syllables together and call it a language. Most fantasy writers do. And most of the time, it sounds like someone sneezed on a keyboard.

Kh'zarthyx'ul. Ae'tharion. Zyx'kael.

You've seen it. I've seen it. We've all seen it. And we've all quietly cringed.

But good conlanging—at least the kind that makes a world feel real to me—isn't about sounding exotic. It's about sounding inevitable. Like these words have been spoken by real people for hundreds of years, worn smooth by use, shaped by the needs of the culture that speaks them.

Here's what I've learned from building Arunaic (the language of my maritime culture) and Low Aelhir (my elven language).

Step 1: Start With Culture, Not Sounds

Most people start conlanging by picking "cool sounds" and mashing them together. That felt backwards to me.

I started with: Who are these people? What do they need to say?

The Aruneans are a maritime culture. Their entire civilization is built on ships, trade, and naval power. So their language reflects that:

• 6+ words for wind (shao = breeze, shaul = gale, shaullue = wind caught in sails)
• Depth/distance is EVERYTHING (linne = shallows, laae = deep, drau = abyss)
• Time is measured by the sun's passage (fenilasra = high passage/noon, feilasra = waking passage/morning)

Even their color words are depth-based. They don't see "blue"—they see where in the water column that blue exists:

• muirrine = sea-blue (open ocean)
• laagerrine = deep loden green (mesopelagic zone)
• nadirrine = abyssal purple-black (crush-depth)

When an Arunean describes something as muirrine, they're not just saying it's blue. They're saying it has the quality of the sea itself.

Even their military ranks encode relationship to the sea:

• Maarendar = Captain ("horizon-commander")
• Draumeir = Admiral ("abyss-master")

Rank isn't just hierarchy—it's how deep you're trusted to sail, how far from shore your authority extends.

But here's where it gets interesting:

Aruneans don't just have "a word for travel." They have laaonarre.

Etymology:

• laae (deep, beyond the coast) + on (across, beyond) + maare (horizon)

Meaning: Traveling beyond the coast and across the horizon—into the unknown.

To an Arunean, real travel isn't just "going somewhere." It's leaving safety behind. It's crossing into the deep, beyond sight of land, where the horizon becomes your only guide.

There's no single English word for this. "Voyage" is close, but it doesn't carry the weight of risk, of leaving the known world. Laaonarre is specific. It's sacred. It's what separates a sailor (muirar) from someone who just owns a boat.

This is what I look for in a conlang. A single word that reveals an entire philosophy. It shows you what a culture VALUES—and what they FEAR.

If your culture is desert nomads, what's THEIR word for the moment you leave the last oasis and head into open sand? What do mountain-dwellers call the act of descending into the lowlands? What do your characters call the thing they do that NO OTHER CULTURE has a word for?

That's where language becomes world-building for me.

Step 2: Choose Sounds That Fit the Vibe

Once I know WHO is speaking, I figure out what they should SOUND like.

Arunaic is:

• Vowel-heavy (a, e, i, o, u dominate)
• Flowing, liquid consonants (l, r, n, m)
• Few harsh stops (no hard K or T clusters)

Why? Because it's a language designed for speaking on ships—over wind, over waves, over distance. You need CARRYING sounds. Long vowels. Resonant consonants.

Compare that to Low Aelhir (my elven language):

• Sharper consonants (kh, th, zh, hard R)
• More guttural
• Shorter vowels

Why? Because elves in my world are older, harsher, more warlike. Their language reflects that—it's harder, more angular, less forgiving.

For me, the sound must match the culture.

Step 3: Build Derivation Rules (So You're Not Just Making Shit Up)

This is where a lot of conlangs risk falling apart in my experience.

They might make up 50 random words, slap them in a glossary, and call it done. But then when they need a NEW word, they just... make up another random word. No consistency. No internal logic.

I found that without derivation rules, I was just maintaining a list of random nouns.

Arunaic Compound Words

Arunaic builds new words by COMBINING root words:

• drau (abyss) + hessa (horse) = drauhessa (drown-horse, mythological sea creature)
• shaul (gale) + lue (caught/captured) = shaullue (wind in the sails)
• thea (return) + lua (light/beacon) = Thealua (the Return-Light, the great lighthouse)

Once you have hessa (horse) and drauhessa (drown-horse), you can build:

• hessar = rider, horseman
• drauhessir = of/relating to drown-horse heraldry
• allahessen = horse dressage (from allan = graceful form + hessa)

Or take bibilausa—combines bibi (cute, small, harmless) + lausa (beast, prey). It means "useless but endearing," the kind of creature that's too cute to hunt. It's the Arunean word for a lapdog. One compound tells you that Aruneans view most animals through the lens of utility.

This means I can generate NEW words whenever I need them. I'm not making shit up—I'm DERIVING words from the system I already built.

Step 4: Make It Speakable (Or It's Just Decoration)

Here's the test I use: Can I say my fantasy words out loud without sounding like I'm gargling gravel? If the answer is no, I scrap it and start over.

Bad fantasy names (in my opinion):

• Kh'zarthyx (how do you even pronounce this?)
• Ae'thalos'kyr (three syllables? four? who knows?)
• Xyl'gothrim (unpronounceable)

These aren't WORDS. They're PUNCTUATION.

Good fantasy names:

• Muirrine (myoor-EEN)
• Drauhessa (DROW-hess-ah)
• Thealua (THAY-ah-loo-ah)

You can SAY these. They have rhythm. They have flow.

If readers can't pronounce your words, they might skip over them—and that's something I wanted to avoid in my own writing.

The Takeaway

What's worked for me:

• Culture-first (what do these people need to say?)
• Sound-appropriate (what should this language sound like?)
• Rule-based (how do I generate new words consistently?)
• Speakable (can I actually say this out loud?)

What I try to avoid:

• Random syllables with apostrophes
• Unpronounceable clusters
• No internal logic
• Just "sounding exotic" for its own sake

That's how I've approached Arunaic. It's still evolving—I'm constantly finding new words I need and derivations I hadn't anticipated. But the foundation (culture → sound → rules) has held up.

If you're working on a conlang for your world, I'd love to hear how you approach it. Do you start with culture? Sound? Grammar? What's been your biggest challenge?
