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.
