Learn English vocabulary by CEFR level

Start with your level or explore vocabulary one step above it.

Every learner word in the unscrambler and the scramble maker carries a checked CEFR level from A1 to C2. Dedicated study lists cover A1–C1; the C2 list is in preparation.

All six bands are explained on the levels page, including why the two highest ones have no list.

Built for learning, not just solving

WordScrambleLab combines a large English recognition list with a carefully prepared learner vocabulary collection. When teaching information is available, you can go beyond the answer and learn the meaning, pronunciation, example, word family and CEFR level.

  • Learning first

    Vocabulary information instead of only possible letter combinations.

  • Evidence-aware CEFR

    Levels show how strongly published vocabulary sources support the classification.

  • Teacher ready

    Turn vocabulary directly into printable classroom activities.

  • Privacy friendly

    Core tools run locally in the browser.

CEFR levels with visible evidence

Vocabulary levels are checked against published vocabulary profiles. When sources disagree, WordScrambleLab shows the disagreement instead of hiding it.

  • ✓✓Strong agreement — Two or more published wordlists agree on the level.
  • Supported — Matches the one wordlist that covers the word.
  • Sources differ — The wordlists place the word in different bands, usually neighbouring ones. Treat the level as approximate.
  • ✓*Reviewed — A conflict examined and decided by the editor, with the reasoning recorded.
  • Draft — Covered by no checked wordlist yet.

Questions

Is WordScrambleLab free?

Yes. Everything here is free and needs no account. The unscrambler, the scramble maker and Practice My Words run in your own browser, so what you type stays on your device. There are no ads and no tracking cookies; the only analytics is a cookieless page count.

How are CEFR levels checked?

CEFR is the Common European Framework of Reference, which bands language from A1 for beginners up to C2 for near-native users. Each level here is checked against published wordlists — the CEFR-J Wordlist v1.5, the Oxford 3000/5000 level bands and, for C1–C2, the Octanove profile — and carries a mark showing how far they agree: ✓✓ two or more agree, ✓ the one that covers the word matches, ≠ they differ, ✓* reviewed by the editor, ⚠ draft. Treat ≠ and ⚠ as approximate.

Can teachers use the worksheets?

Yes. The scramble maker builds level-appropriate worksheets with an answer key, the library has ready-made packs with a classroom procedure and timings, and all of it may be copied, printed and adapted for teaching under CC BY-NC-SA 4.0, with credit and no resale.

Does WordScrambleLab work offline?

Yes. After your first visit, the tools keep working without a connection: pages and word lists you have used are stored in your own browser and read only when the network is unavailable. While you are online, the site always loads fresh from the network, and nothing about your searches is sent anywhere either way.

Which dictionaries and vocabulary sources does WordScrambleLab use?

Different sources are used for different purposes, rather than one dictionary. Definitions and examples in the learner cards are written for learners and checked against established learner dictionaries. CEFR levels are evidence-graded against published vocabulary profiles, and pronunciation comes from the CMU Pronouncing Dictionary. A separate, much larger wordlist is used only to recognize other English words that do not yet have teaching data. See Methodology & sources for the exact datasets, versions, licences and coverage.

How does the pronunciation button work?

It uses the speech voice already built into your phone or computer, so nothing is downloaded and no recording is stored here. Quality varies by device, and a synthetic voice occasionally gets a word wrong. Treat it as a rough guide rather than a model to imitate; the written transcription beside each word is the more reliable of the two. If your device has no English voice, the button says so and explains how to add one.

What do ? and * mean in the unscrambler?

Both stand for a blank tile: a letter you do not have. TEACH?R finds teacher. Up to three blanks are used in one search, because more would match most of the dictionary.

Can I use WordScrambleLab in Thai?

Yes. The unscrambler, the level word lists, Practice My Words, the scramble maker and the teaching resources all have Thai pages. Use the EN | ไทย switch in the header; the word data itself — meanings, examples, word families — stays in English, because English is what you are learning.
