Build Better Vocabulary for Real Life

English may not be your first language, but you use it in many parts of your life. And building your vocabulary gives you more words to understand, express your ideas, and communicate with confidence.

Understand more. Express your ideas better.

A stronger vocabulary makes it easier to understand what you're reading and learning. It helps you follow complex ideas, write clearly, join discussions, and communicate what you know.

English Can Open More Doors in Life

English is more than a language. It can connect you to opportunities, people, knowledge, and experiences around the world.

Nearly 30% of people worldwide speak English. That's more than 2.3 billion people who use English to communicate across countries and cultures.

English can help you:

  • Grow your career and access more opportunities
  • Work with people around the world
  • Study and learn from more resources
  • Travel and connect with people more easily

Why games outperform studying for vocabulary.

Four findings, in the order they build on each other.

  1. 01

    Spacing beats cramming

    Memory for new material decays within days unless it is revisited. A short daily round is spacing, whether or not it feels like study.

    Ebbinghaus, 1885
  2. 02

    Being tested beats re-reading

    Retrieving an answer builds memory faster than reviewing it. Every round asks you to produce the word, not just recognise it.

    Roediger & Karpicke, 2006
  3. 03

    Recognising a word is not knowing it

    Understanding a word you meet is not the same as reaching for it yourself. That gap is where most learners stall.

    Nation, 2001
  4. 04

    Effortful recall is what sticks

    Recall that takes a little effort lasts longer. Hence the timer, and a hint you have to ask for.

    Bjork & Bjork, 2011

How to Answer "Tell Me About Yourself" When English Isn't Your First Language

The words that stall in an interview are not the ones you never learned. They are the ones you read constantly and say almost never. A sixty second test to find yours, a fifteen word list to fix them, and what to do in the room when one refuses to come.

Common questions.

If something's still unclear, reach out. We're building this for real learners and the feedback helps shape what gets built next.

Yes, all three games and your progress dashboard are free to play. WordSensei is supported by the ads shown on the site, which cover our servers and development. We may add optional paid features for advanced analytics in the future, but the core will always be free.
Yes, and it is worth saying that most people who ask this are further along than they think. If you can read this page, comprehension is not your problem. What is missing is usually production: recalling the right word quickly enough to use it. Start with the easier word sets and work up.
Duolingo teaches a language from the ground up: listening, grammar, reading, the lot. WordSensei assumes you already have the language and are stuck on range, which is the usual position for someone who works or studies in English but did not grow up in it. Different problem, different tool. Using both is perfectly reasonable.
No. WordSensei runs entirely in your browser on desktop or mobile. Nothing to install, nothing to update.
English vocabulary is our focus for now. However, we're expanding the interface to support more native languages so learners can navigate the platform in their own language.

Tell us what you are stuck on

If a word set is missing something you need for your work or your studies, we would rather hear it than guess. Questions about the site are welcome too.
