Why Learn Welsh with Dragon Lingo?
Spaced Repetition
Our SM-2 algorithm shows you words right before you'd forget them — the same proven method used by Anki. See how it works →
Daily Streaks
Build a study habit that sticks. Track your current and longest streaks, and watch your progress on a GitHub-style activity heatmap.
Beginner to Fluent
From everyday greetings to mutations, conjugations, and idioms — structured by level so you always know what's next.
Achievements & Badges
Unlock dozens of badges for streaks, vocabulary milestones, review counts and completed topics as you progress.
Friends & Leaderboards
Add friends, compare streaks and progress, and keep each other motivated with a bit of friendly competition.
Your Own Personal Decks
Create private decks of your own words and phrases — for work, family or travel — studied with the same spaced repetition.
How It Works
Sign Up Free
Create an account in seconds — just a username, email and password. No card details, ever.
Pick Your Level & Pace
Choose Beginner, Intermediate, Advanced or Fluent as your active level, and set how many new words you'd like to learn per day — relaxed, steady, brisk or intensive.
Study Daily
Rate how well you knew each card — Again, Hard, Good or Easy — and let the SM-2 algorithm schedule your next review automatically. "Again" cards come straight back round before your session ends.
Type to Test Yourself
Choose Typed Mode at the start of a session for a stricter recall test — every card shows English first and you type the Welsh word from memory, spelling and mutations included.
Track Your Progress
Watch your streaks grow, review your activity heatmap, and see your answer-quality breakdown over time.
Print & Practise Anywhere
Generate a printable cheatsheet for any topic, or use Random and Hard Words modes for extra practice.
Who Is It For?
Whether you're a complete beginner who's never spoken a word of Welsh, a parent learning alongside your children at a Welsh-medium school, brushing up before a Cymraeg exam or job interview, or simply reconnecting with family heritage — Dragon Lingo is built to fit around your life.
Many learners use it as a standalone course from "Bore da" through to natural conversational Welsh, while others use it as a daily vocabulary "gym" alongside a class, app or course they're already following. Just 5–10 minutes a day is enough to make steady progress thanks to spaced repetition.

What is the SM-2 algorithm?
The same spaced-repetition method used by Anki — it adjusts how often you see each word based on how well you know it. Full details on How It Works.
Do I need any prior Welsh?
No — Beginner decks start from absolute scratch with everyday greetings and basic vocabulary.

🧠 How Spaced Repetition (SM-2) Works With Your Decks
▸Every card in every deck below has its own personal schedule, tracked separately for you. When you study a deck, you're not just working through a flat list from top to bottom — you're seeing exactly the cards that are due for review right now, mixed with a handful of new cards introduced at the daily pace you chose (see Settings).
Each time you rate a card, the SM-2 algorithm decides when it should reappear:
- Again — the card stays due today and keeps reappearing in your queue (moved to the back, so other cards come first) until you get it right. It hasn't "stuck" yet, so it won't disappear from Due Now.
- Hard — you knew it, but it was a struggle. It comes back again fairly soon — a smaller jump than Good.
- Good — a solid recall. The gap before its next review grows: typically 1 day → 6 days → then roughly ×2.5 each time after that (1 → 6 → ~15 → ~37 days, and so on).
- Easy — instant recall. The gap grows even faster than Good, so well-known words fade into occasional refreshers measured in weeks or months.
This is why a deck you've "completed" can still show cards as due later — it's not re-testing everything, just the specific words that are due to resurface based on how well you knew them last time. The repetition isn't random or evenly spaced: words you find easy are repeated less and less often over time, while words you find tricky are repeated more frequently until they finally stick. Over weeks, this naturally concentrates your study time on your weak spots rather than wasting it re-confirming things you already know.
Decks
Create a personal deck
This creates a private topic just for you — perfect for words from work, family, a holiday, or anything not already covered. Once created, you can add your own Welsh/English word pairs to it. It'll appear in your deck list under 📝 My Decks, and works just like the built-in topics: spaced repetition, due reviews, streaks, printable cheatsheets — all of it. Only you can see it.
