How it works

From “I've seen that word” to using it without thinking.

1

Discover your level

A quick level check estimates how many advanced words you already know. Wordsure then skips what you know and starts exactly where your vocabulary runs out.

  • See your level, like C1.1, and how many words to the next one
  • Words picked for you, not for an average learner

2

Learn one word at a time

Every word comes with everything you need to actually use it: a clear meaning, pronunciation, a natural example, synonyms, collocations and where the word comes from.

  • Hear it spoken, then see it in a real sentence
  • “I know it” skips a word in one tap

3

Practise it five ways

Recognising a word isn't the same as owning it. Each new word goes through meaning, fill-the-gap, synonyms, sentence building and listen-and-spell before it joins your reviews.

  • Fill the gap in real sentences
  • Match synonyms and meanings
  • Listen, then spell it from memory

Review right before you'd forget

Spaced repetition brings each word back at the moment it starts to fade, so a few minutes a day is enough to keep everything you've learned.

  • Daily streaks and a progress calendar
  • Only the words that are due, so sessions stay short

Every word has a story

Learners stay for the meaning. Everyone stays for the story.

Wordsure doesn't stop at definitions. Each word shows where it came from, which is often the detail that makes it stick. Catch a new one every day in our Word of the Day videos.

Questions

Good to know

Who is Wordsure for?

Upper-intermediate and advanced learners (B2, C1 and C2) who already speak English well and want the precise, expressive vocabulary that makes them sound natural. Native speakers who like words use it too.

How does the level check work?

You see a series of words and say whether you know them, with a few “what does this mean?” questions mixed in. Some words are invented, so guessing doesn't pay. Wordsure estimates your vocabulary, shows your level, and picks new words just above it. You can also choose your level yourself.

How much time do I need?

A few minutes a day. You choose your daily goal for new words, and reviews only show up when a word is due.

Is it only single words?

No. The library also has phrasal verbs and idioms, each with a meaning, examples and synonyms.

Is there an iPhone version?

Wordsure is coming to Android first, with iPhone following soon.

A few minutes a day. Words you'll actually use.
