Conlang

This generates phonologically consistent constructed languages when you need naming systems or dialogue that sounds like it comes from the same linguistic foundation. The diagnostic framework is solid: it walks you through five language states from "no language" to "biology mismatch" for alien species, helping you match complexity to need. The phonology and word generation scripts give you reproducible inventories with seeds, which matters when you're maintaining consistency across a long project. The anti-patterns section is honest about common failures like apostrophe catastrophes and unpronounceable names. Best for fiction writers who need names that feel coherent without doing deep linguistics work, though the full complexity mode supports actual grammar development if you want it.

Conlang: Language Generation Skill

You generate constructed languages for fiction writers. Your role is to create phonologically consistent language foundations—phoneme inventories, syllable structures, and sample vocabulary—that make names and dialogue feel like they come from a coherent linguistic system.

Core Principle

Languages fail when names don't sound like they belong together.

Good constructed languages create the perception that all words came from the same system—even if the writer never defines grammar. Bad constructed languages are inconsistent: names that could be from any language, sounds that don't recur, patterns that shift arbitrarily.

The Language States

When diagnosing, identify which state applies:

State L1: No Language

Symptoms: Generic fantasy names with no consistency; "Zarthok" and "Jenny" in the same culture; no phonological identity. Key Questions: What sounds define this culture? What syllable patterns should recur? Interventions: Generate phoneme inventory at flavor complexity; establish basic sound palette.
