We kept asking the same question: if the brain is built to learn languages, why does it feel so hard the second time around?
These essays are what we found: the science of how your brain picks up a language, what makes languages work the way they do, and what that means if you're trying to become fluent. Read them in any order.

Most language learning tools feel like progress but don't produce fluency. They're optimized for something else entirely.

How languages evolve, mix, and end up the way they do
