🌍 LinguaEvo

An interactive evolutionary language simulator — Watch languages grow and change naturally over time, just like real historical linguistics.

---

What is LinguaEvo?

LinguaEvo lets you create a starting "proto-language" and then simulate how it evolves over centuries through realistic sound changes.

You define:

• Phoneme inventory (sounds)
• Starter vocabulary
• Sound change rules (e.g., p → f before a vowel)

Then watch your language naturally transform across multiple generations — with audio playback so you can hear the evolution.

It’s designed for:

• Fantasy & sci-fi worldbuilders
• Game developers
• Writers
• Language enthusiasts
• Educators teaching historical linguistics

Features

• Interactive Proto-Language Creator — Define phonemes, vocabulary, and rules with a beautiful UI
• Multi-Generation Evolution — Simulate 100, 300, or 500 years at a time
• Realistic Sound Changes — Supports environment rules (e.g. _V = before vowel)
• Audio Playback — Click 🔊 to hear words in their original and evolved forms
• Language Family Tree — Track and switch between multiple generations
• Real-World Example — One-click "Latin → Romance Languages" demo
• Export — Download your full language family as JSON

How to Use

1. Create a Language

   • Add phonemes (sounds)
   • Add starter words with meanings
   • Define sound change rules

2. Load Example (Recommended for first time)

   • Click "Load Latin → Romance Example" to see real historical evolution

3. Evolve

   • Choose simulation length (100 / 300 / 500 years)
   • Click "Evolve X Years"
   • Use "Evolve Again" to continue the evolution

4. Explore

   • Switch between generations
   • Click speaker icons to hear the words
   • Export your language family

💡 Why This Project?

Most constructed-language tools let you design a language statically.
LinguaEvo lets you grow a language the way real languages evolve through history.

It transforms abstract linguistics into something:

• Visual
• Audible
• Interactive

🔮 Future Ideas

• 🌍 Culture contact (two languages influencing each other)
• 🌳 3D language family tree visualization
• 📜 Grammar evolution simulation
• ✍️ Procedural text generation in evolved languages
• 📄 Export as grammar PDF + audio samples
