description: >
  Constructed language design beyond phonetic palettes — morphology, syntax, the Sapir-Whorf
  hypothesis as worldbuilding tool, and the conlang-to-culture pipeline. Use when a culture
  needs linguistic depth beyond naming conventions, when language should encode worldview, or
  when the user asks about creating fictional languages.

# Conlang Craft — Language Shapes the World

`naming-system` gives each culture a sound palette for consistent names. This skill goes deeper: morphology, syntax, and the principle that **language shapes how speakers think about reality**. Tolkien built the world to give his languages a home.

## The Depth Gradient

| Level | What You Build | When You Need It |
|-------|---------------|-----------------|
| 1 — Sound Palette | Phoneme inventory, syllable rules | Consistent names (`naming-system`) |
| 2 — Cultural Flavor | Key words, idioms, untranslatable concepts, grammatical quirks | Novel with linguistic color |
| 3 — Functional Grammar | Syntax, verb system, enough for spoken dialogue | Epic fantasy, media properties |
| 4 — Full Conlang | Complete grammar, historical linguistics, language families | Tolkien-scale projects |

Level 2 is this skill's sweet spot for most fiction.

## Morphological Typology

| Type | How Words Are Built | Feel | Cultural Implication |
|------|-------------------|------|---------------------|
| **Isolating** | One morpheme per word, word order carries meaning | Clean, precise | Values directness, efficiency |
| **Agglutinative** | Meaningful pieces strung together | Elaborate, systematic | Values precision, categorization |
| **Fusional** | Affixes carry multiple simultaneous meanings | Compact, layered | Comfortable with complexity |
| **Polysynthetic** | Sentences compressed into single words | Dense, holistic | Sees events as unified wholes |

Fiction shortcut: choose a type and show it in a handful of key words. One example tells the reader how the language works.

## Sapir-Whorf as Worldbuilding Tool

### What a Language Has
Reveals what a culture notices: 30 words for sand (desert culture), precise wind vocabulary (seafaring), seven words for honor.

### What a Language Lacks
Even more revealing: no word for privacy, "I" and "we" are the same word, no future tense, no passive voice.

### Grammatical Worldview
- **Evidentiality markers**: Must mark whether information is firsthand, hearsay, or inference
- **Honorific systems**: Every sentence encodes speaker-listener power dynamic
- **Noun classification**: By animacy, shape, sacredness, danger — reveals what matters
- **Tense systems**: No past tense (only completed/ongoing) → different relationship to history

## The Conlang-to-Culture Pipeline

Tolkien's direction — language first, culture derived:
1. Create phonological palette (naming-system)
2. Choose morphological type, design example words
3. Add 2-3 grammatical quirks
4. Ask: what cultural values do these features imply?
5. Build culture outward from linguistic implications

The reverse (culture → language) is what `naming-system` does. This adds the forward direction.

## Writing Systems

| System | Implies |
|--------|---------|
| Pictographic | Early development, visual culture |
| Logographic | Long literate history, high literacy barrier |
| Syllabary | Intermediate complexity, often from cultural contact |
| Alphabet | High abstraction, spreads through trade |
| Abugida | Systematic analysis by the culture's scholars |

Design question: Who invented writing (merchants, priests, bureaucrats?) and why? The origin shapes what gets written and who reads.

## Practical Conlang for Fiction Writers

What you actually need, by project type:

| Project | Minimum Depth | What To Build |
|---------|--------------|--------------|
| Novel with one non-English culture | Level 2 | Sound palette + 20 key words + 5 idioms + naming conventions |
| Novel with multiple cultures | Level 2 per culture | Sound palettes that contrast + key vocabulary showing different values |
| Fantasy epic with deep linguistics | Level 3 for main culture | Functional grammar, 100+ word lexicon, in-language dialogue |
| Tolkien-scale language project | Level 4 | Full grammar, historical linguistics, related language family |
| Game/RPG setting | Level 2 | Sound palettes + place name generators + key terms |

## Relationship to Other Skills
- **Naming-System**: Level 1 foundation; this extends to Levels 2-4. **Cultures-Societies**: Sapir-Whorf connects language to all seven pillars. **Religion-Design**: Sacred languages, liturgical registers. **History-Builder**: Languages change over time; historical events leave linguistic traces. **Writing/diction**: Prose from a culture's perspective should harmonize with its linguistic character.
