Recursio: Learn English

Recursio helps English learners stop forgetting the words, phrases, and grammar they already study.

Build your own vocabulary, practice what matters to you, and let Recursio bring weak spots back into review. Instead of following a fixed course path, you choose what to learn: useful words, everyday phrases, grammar topics, sentence practice, speaking practice, and focused Coach sessions.

NEW: Phrases
Recursio now teaches phrases, not just single words. Save phrasal verbs, collocations, idioms, and everyday conversational chunks like "look forward to," "make a decision," or "to be honest." Phrases live in the same vocabulary space as your words — just switch between the Words and Phrases filters. They practice through the same exercises and return in your daily Mixed Review, so the phrases you save today come back at the right time tomorrow.

Recursio is designed for learners who can already work in English at a basic level. Definitions, examples, grammar explanations, and practice prompts are shown in English, so you stay inside real English instead of constantly translating.
