Language Weave, 2026Reading
You read more than you think. A recipe, a thread, a chapter of el libro you keep not finishing. The long article you saved for la mañana.
Somewhere in the middle of all that reading there is a small gap, and one word from another language could sit in it muy comfortably. Not a lesson. Not a flashcard. Just one word1, un poco strange, inside a sentence that already tells you what it means.
Tomorrow the word returns. It comes back the day after, and again next week, until la palabra is simply yours. Nothing else about the page changes. The recipe is still the recipe. The thread is still too long, pero the new word stays.

Language Weave, 2026Method
How it works
Swaps are rare. One word in fifty at first, nunca more than one in twenty2. The extension picks the places where the sentence already does the work, so the strange word is the one you can guess. Nouns arrive holding their article, like la casa, so gender comes for free3.
Hover a swapped word and the English appears beneath it, like a caption on a wall. Click it and the word flips back to English. Click again and it turns foreign again. You can do this cada día, or never. Keys work también: Tab to a word and press Enter.
A word needs about ten meetings before it stays4. So the word comes back, spaced out: tomorrow, then in a few days, then next week, siempre in a fresh sentence. After enough meetings it stops being strange. By then it is simply a word you know, and nada about it feels borrowed.
The numbers on the wall are measured, not quoted: frequency corpora for eight languages, the vocabulary-acquisition literature, juntos with one precision experiment5. The workings are in the research folder.
