The most important words to learn in English

How do you know which are the most important words to learn in English? The fully revised and up-to-date Oxford 3000™ word list provides an essential core vocabulary for learners of English graded by CEFR level. Every Oxford 3000 word in the dictionary is clearly marked with a key symbol and all the definitions in the Oxford Advanced Learner’s Dictionary are written using Oxford 3000 words. So if you learn and use the Oxford 3000 word list, you can look up and understand the definition of every word in the dictionary.

The Oxford 3000 is the core vocabulary you need up to B2 level (upper intermediate). Now with the Oxford 5000™, we’ve added an extra 2,000 words to take your vocabulary to a higher level (B2 to C1, or upper intermediate to advanced).

And if you are learning English for academic purposes, for example at college or university, the dictionary also highlights vocabulary from OPAL™ – the Oxford Phrasal Academic Lexicon – to help you learn the essential vocabulary for academic writing and speaking.
