The Common European Framework of Reference (CEFR) describes language ability in six steps. Every entry in this dictionary carries a level label showing at which step a learner typically needs the word.
| Level | Name | You can… |
|---|---|---|
| A1 | Beginner | use familiar everyday phrases and introduce yourself |
| A2 | Elementary | handle simple, routine exchanges about immediate needs |
| B1 | Intermediate | deal with most travel situations and describe experiences and plans |
| B2 | Upper-intermediate | interact fluently with native speakers and write clear, detailed text |
| C1 | Advanced | express ideas fluently and use language flexibly for work and study |
| C2 | Proficient | understand virtually everything and express yourself precisely |
Level is not the same as frequency
A word's level says how hard it is to learn; how common it is in everyday speech is a different question. however is common but not simple; kitten is easy but rare. Use both: start with common words at your own level and one above.
Practical rule: aim at words one level above your own. Words at your level are review; words two levels above rarely stick.
Use the CEFR Level filter on any search-results page and on Phrases & Expressions to see only the level you are working on.
