OpenWords - Learn Words

OpenWords helps you actually remember the words you look up. It is a deep-dive dictionary and vocabulary tool built for learners who want to truly master English, Dutch, Polish, or Russian.
Most apps show you a translation and then you forget it. OpenWords is built to turn those lookups into long-term knowledge. The app provides translation support for English, Dutch, German, Spanish, French, Italian, Turkish, Russian, Polish, Czech and Simplified Chinese.

DICTIONARY WITH CONTEXT
- Multi-sense lookup: Don't just get a translation. See every meaning and save only the specific sense that fits your current context.
- CEFR levels & frequency: Know if a word is A1 or B2. See if it's high-frequency daily speech or niche vocabulary so you can prioritize your learning.
- Word families: View related roots and forms to understand patterns and grow your vocabulary faster.
- Examples & phrases: See how words actually function in real sentences.
