About

Rigl

Features
Read full description

Rigl-lingvo is built for one specific goal: helping you actually use English phrasal verbs and irregular verbs in spontaneous speech. Instead of memorizing long lists, you practice short real-life prompts, type or say your answer, get instant feedback, and learn the natural version of the phrase. Rigl focuses on phrasal verbs, irregular verb forms, and everyday English expressions that are hard to master through traditional exercises. Rigl is different from general language apps like Duolingo, Babbel, Busuu, Memrise, or ELSA Speak. Those apps are useful for broad language learning, vocabulary, grammar, or pronunciation. Rigl is narrower and more practical: it trains you to recall phrasal verbs and the right irregular forms quickly, and use them naturally in context. What you can do in Rigl: • Practice English phrasal verbs in short speaking-style exercises • Drill irregular verbs and their three forms (go – went – gone) in real sentences • Train spontaneous answers instead of passive recognition • Get feedback when your answer is almost right or unnatural • See better, more natural alternatives • Use hints when you get stuck • Practice by typing or using your voice • Browse focused catalogs of phrasal verbs and irregular verbs with translations • Learn through context, not isolated flashcards Supported interface and explanation languages: Chinese, French, German, Italian, Portuguese, Russian, and Spanish. Rigl is designed for learners who already know some English but still freeze when they need to use natural expressions — or the right verb form — in real conversation. If you want to stop recognizing phrasal verbs and irregular verbs only after you see them — and start using them yourself — Rigl is made for that.
