How to Name a Dwarf: Khuzdul and Tolkien's Secret Language

Here's a fact that surprises most casual Tolkien readers: Thorin, Balin, Dwalin, Fíli, Kíli, and the entire dwarven cast of The Hobbit don't have real dwarven names. Those are aliases. The names you see in the book are Mannish nicknames the dwarves use in public. Their real names — in their actual language, Khuzdul — are kept secret. Most dwarves go their entire lives without revealing their true name to anyone outside their clan.

This guide explains the trilingual naming system Tolkien designed for dwarves, the linguistic logic behind it, and how to apply it to D&D characters, original fantasy fiction, and game design.

The Three Names of Every Dwarf

Tolkien's dwarves operate with three name layers:

1. Khuzdul (inner) name — the dwarf's true name in their secret native language. Known only to clan members and rarely written down. Never spoken in front of outsiders.
2. Outer (Mannish) name — a public alias drawn from the language of nearby Men. This is the name humans, elves, and hobbits use to refer to the dwarf.
3. Clan affiliation — Durin's folk, Firebeard, Stiffbeard, etc. Indicates which of the Seven Houses of the Dwarves the dwarf belongs to.

In The Hobbit, the company are all of Durin's folk (House of Durin), using Mannish/Old Norse aliases (Thorin, Balin, Dwalin, etc.). Their Khuzdul names are unknown to us — Tolkien never wrote them down, because the conceit is that no outsider, including the author, gets to know.

Why Khuzdul Is Secret

The in-world reasoning: dwarves believe their true names carry power and identity that should not be shared casually. To know a dwarf's Khuzdul name is to know them intimately. The Old Norse-derived names you see in the book are a cover story — names that signal "I am a dwarf" without actually revealing dwarven identity.

The out-of-world reasoning: Tolkien wanted dwarves to feel mysterious and inwardly-turned. Their public names being from a different culture entirely (Old Norse) emphasizes that what you see of dwarves is never their full self. The Khuzdul names that survive in the legendarium are mostly place names — Khazad-dûm (Dwarrowdelf), Kibil-nâla (Silverlode river), Azanulbizar (the Dimrill Dale).

Mannish (Old Norse) Naming for Dwarves

When picking a "Mannish" dwarven public name, Tolkien drew almost entirely from the Dvergatal — the "Catalog of Dwarves" in the Völuspá (a poem in the Poetic Edda). The Dvergatal lists 80+ named dwarves, and Tolkien lifted his cast directly:

• Thorin, Thráin, Thrór — all from the Dvergatal
• Bifur, Bofur, Bombur — Dvergatal
• Balin, Dwalin, Glóin, Óin — Dvergatal
• Fíli, Kíli, Náli, Dáin — Dvergatal

This is the Mannish layer. For your own dwarven characters, the Viking name generator gives you exactly this register — Old Norse compound names with the same phonetic register as Tolkien's dwarves. Sigurðr, Hákon, Þorvarðr, Bjǫrn all sound dwarven-appropriate because they share linguistic DNA with the canonical Tolkien dwarven names.

Phonetic features that make a name feel dwarven-Mannish:

• Hard consonants (especially th-, gr-, kr-, dr-)
• Compound structure ("X + Y" with meaning)
• Often ends in -r, -i, or -in
• 1-3 syllables, never very long

Inventing Khuzdul (Inner) Names

If your story requires a dwarf to reveal their Khuzdul name — to a trusted partner, in a deathbed scene, or during a ritual — you need to invent it. Tolkien gave us partial structural information:

Khuzdul phonology:

• Semitic-inspired (Hebrew/Arabic structural features)
• Three-consonant root system (like Hebrew)
• Sounds: kh, zh, ai, ai, u, aw
• Common consonants: k, kh, b, b, d, g, l, m, n, r, s, sh, z, zh

Sample Khuzdul roots from what Tolkien wrote:

• KhZD — dwarf, dwarven
• BRZ — red, ruddy
• BND — head, peak
• MBN — heap

Names constructed from these roots tend to be:

• Mahal (Aulë's dwarven name — short, hard-consonant)
• Khuzd (a dwarf)
• Khazad (dwarves, plural)

For original Khuzdul-flavored names, follow this pattern: 1-2 syllables, hard consonants, often a guttural or fricative element (kh, zh, gh).

Examples you can invent: Kharûn, Bazgil, Kibrin, Dharâz, Mukhâz.

D&D 5e Dwarves

The Player's Handbook gives Dwarven names that are explicitly Tolkien-derived:

• Male: Adrik, Alberich, Baern, Barendd, Brottor, Bruenor, Dain, Darrak, Delg, Eberk, Einkil, Fargrim, Flint, Gardain, Harbek, Kildrak, Morgran, Orsik, Oskar, Rangrim, Rurik, Taklinn, Thoradin, Thorin, Tordek, Traubon, Travok, Ulfgar, Veit, Vondal
• Female: Amber, Artin, Audhild, Bardryn, Dagnal, Diesa, Eldeth, Falkrunn, Finellen, Gunnloda, Gurdis, Helja, Hlin, Kathra, Kristryd, Ilde, Liftrasa, Mardred, Riswynn, Sannl, Torbera, Torgga, Vistra
• Clan: Balderk, Battlehammer, Brawnanvil, Dankil, Fireforge, Frostbeard, Gorunn, Holderhek, Ironfist, Loderr, Lutgehr, Rumnaheim, Strakeln, Torunn, Ungart

D&D added a fourth layer: Clan names with hereditary continuity — Battlehammer, Fireforge, Frostbeard. These work like modern surnames (which medieval European cultures didn't really have — see medieval surnames for the historical version).

Phonetic patterns in D&D dwarven names follow Tolkien's Old Norse template fairly closely.

Female Dwarven Names

Tolkien wrote very little about female dwarves. He stated in the appendices that "they are so like the dwarven-males in voice and appearance, and in garb if they need go on a journey, that the eyes and ears of other peoples cannot tell them apart" — implying that female dwarves look and sound much like male dwarves, including in naming.

D&D 5e expanded this with explicitly feminine names (Diesa, Audhild, Helja) but kept the same phonetic register.

For original female dwarven names, you can either:

1. Use Tolkien's approach: same phonetic register, dwarven names that don't visibly gender-mark
2. Use D&D's approach: slightly softer endings (-a, -ya) for feminine names

Building a Dwarven Character Name

Putting it together, a full dwarven character identity looks like:

1. Public name (Mannish / Old Norse): Thorin, Bjǫrn, Hákon — generate via Viking name generator or pick from the Dvergatal
2. Clan / House affiliation: of Durin's Folk, of Stonefist Clan, Ironfist
3. Optional Khuzdul name (if revealed): Kharûn, Dharâz — invented to feel Semitic
4. Optional descriptive epithet: the Strong, Forge-Master, Hammerhead

Examples:

• Thorin Oakenshield, of Durin's Folk (canonical)
• Hákon Stonefist, of the Ironbeard Clan (original)
• Brand Battle-axe, son of Hakon, of the Hill-Dweller Clan (with patronymic added)
• Vondal Thornhammer of Mithril Hall (D&D-style)

For non-Tolkien-derived dwarven worlds, you can substitute the Old Norse layer with Anglo-Saxon or Germanic names (the medieval name generator provides this register). This shifts the cultural register slightly — more Anglo-Saxon dwarves feel more grounded, more earthbound; Old Norse dwarves feel more raid-and-trade.

When to Reveal the Secret Name

Narratively, a dwarf revealing their Khuzdul name is a major plot moment. Possible occasions:

• Marriage / oath-binding — the dwarf commits identity to a partner
• Deathbed — the dwarf gives their true name to their heir before passing
• Ritual / ceremony — official clan business where the inner name is invoked
• Crisis of identity — the dwarf claims their Khuzdul name in defiance of being denied dwarven recognition

Used sparingly, this moment carries enormous weight. Used too often, it becomes another exotic flourish.

Five Patterns to Use

For your dwarven character, pick one of these structural approaches:

1. Pure Tolkien: Old Norse public name + Khuzdul kept secret + clan affiliation. The strict canonical approach.
2. D&D: Public name (Old Norse-style) + hereditary clan surname. Treats clan as a modern surname.
3. Norse-fantasy: Use Viking-style names directly with patronymics (Hákon Eiríksson, of the Iron-Beards). Less Tolkien-faithful but vivid.
4. Anglo-dwarven: Substitute Anglo-Saxon names for the Mannish layer (Aldric, Wulfgar, Mildred). Earthier feel.
5. Original conlang: Invent your own dwarven language entirely. More work, more reward.

The trilingual structure is what makes Tolkien's dwarves feel like a culture, not just a fantasy race. They have inner lives we never fully see — and that depth carries through to every dwarven character in the broader fantasy tradition.

Pick one structure, apply it consistently, and your dwarves will feel deeper than the page count suggests.
