Rootles is a small collection of daily word games about the roots of English — the buried Latin, Greek, Norse, French, and Old English pieces that quietly assemble the words we use every day. Most word games reward the spellings you already know. Rootles is about the layer underneath: why a word means what it means, and how words that look nothing alike turn out to be cousins.
The idea
English is a borrowing language. It has spent fifteen centuries absorbing vocabulary from everywhere it touched, and the seams are still visible if you know where to look. Fracture, fragment, and infringe all carry the Latin frangere, "to break," even though only one of them still looks like it. Transfer and relate share the same root for "carry" wearing two different masks. Once you start noticing these patterns — a prefix that shifts its spelling to fit the next sound, a root that surfaces as duct in one word and duce in another — you can't stop. Rootles is built to give you that habit, a few minutes at a time.
The games
There are six, each taking a different angle on the same material. Graft asks you to hop from one word to another by a shared root, finding hidden routes between two distant words. Dig has you cut a single word at its seams and match each piece to its meaning. Grow plants one ancient root and challenges you to grow as many English words from it as you can. Germinate asks you to trace each part of a word back to the language it came from. Branch traces a word's family tree, from its Proto-Indo-European root down through Germanic or Latin to the modern English word. Mint hands you a set of ancient roots and endings and asks you to coin brand-new words that don't exist yet. A new puzzle for each appears every day (Saturdays rest), the same for everyone, so you can compare notes.
The six strata
Throughout the games you'll see a recurring palette: six colors standing for the six great layers of English vocabulary — Old English, Old Norse, Latin, Old French, Greek, and Arabic. The colors aren't decoration; they're a quiet teaching tool. Handle enough words and you start to feel which stratum a word came from before you're told — the same way you'd learn rock layers by digging through them.
How it's made
Rootles runs entirely in your browser — there are no accounts, and your progress and streaks stay on your device. The word data is assembled from openly licensed sources and cross-checked against Wiktionary so the etymologies are honest rather than guessed; the full list of sources and licenses lives in the project's credits. The site is free to play, supported by ads; how that works, and your choices around it, are described in the privacy policy.
Who made it
Rootles is an independent project made by one person who likes etymology a little too much. It's still growing — new roots and refinements land regularly. If you spot a wrong root, a puzzle that feels off, or just have an idea, I'd genuinely like to hear it: [email protected].
