Connect cultures.
LinguaCommons is a free, open library of the world’s languages — past, present and invented. Structured guides, spaced-repetition vocabulary, and the study methods that research actually supports. No ads, no sponsors, no paywall.

How it works
A library, not a course — and definitely not a game.
There is no streak to protect and nothing to unlock. LinguaCommons gives you the reference material serious learners actually need, organised so you can find it, and sourced so you can check it.
1.Pick a language
Start from your own native language, not from English. Guides are written for the pair — Yorùbá from French reads differently to Yorùbá from Japanese.
2.Follow a structured path
Every guide is CEFR-banded A1 to C2, with pronunciation contrasts, grammar in plain language, and worked examples rather than word lists.
3.Drill it until it sticks
Pair the guide with a spaced-repetition deck of the highest-frequency words, and the study methods that research actually supports.
Every language is worth keeping.
Endangered tongues, regional dialects, ancient scripts and constructed worlds — all held in the same commons, free for anyone who wants them.
