What C2 vocabulary means

C2 learners understand virtually everything they read or hear, summarise information from different sources and express themselves precisely, distinguishing finer shades of meaning. C2 vocabulary includes literary, formal and specialised words such as meticulous, ephemeral, paramount and disseminate.

C2 words are rare even for native readers; many appear only a few times in a whole novel. Knowing them is what makes literary fiction, academic writing and specialist texts feel effortless.

Where this list comes from

The C1 and C2 words come from the Octanove Vocabulary Profile by Octanove Labs, which extends the CEFR-J approach to advanced levels. The list is licensed CC BY-SA 4.0.

Okuzeka kept the single-word headwords and sorted them by word frequency. Other lists, such as the Cambridge English Vocabulary Profile or the Oxford 3000/5000, may give some words a different level, and a word's level can depend on the meaning being taught.

FAQ

Frequently asked questions

How many words are in the C2 list?

869 single-word headwords. From A1 to C2 the lists contain 8,498 words in total.

Can I download the C2 word list?

Yes. Use the copy button to copy the whole list, or the words you filtered, and paste them into your own word list or flashcard app.

Is this the official Cambridge or Oxford list?

No. It is based on the CEFR-J and Octanove word lists. Cambridge and Oxford publish their own lists, which may level some words differently.

How long does it take to learn the C2 words?

It depends mostly on how much you read. Twenty minutes a day at your level means meeting C2 words many times, and those repeated meetings are what make words stick, far more than a list.

How can I check the level of a single word?

Type it into the English word level checker to see its level, frequency and meaning.
