Ideal for intermediate-level learners (CEFR B1-B2), the dictionary has more than 35,000 definitions in clear, simple English. Essential words that learners need to know are clearly marked, helping them to make faster progress by focusing on the most important vocabulary to master at intermediate level. These essential words have been identified using English Profile, a ground-breaking collaborative project between two departments of the University of Cambridge: Cambridge University Press and Cambridge Assessment. Other features include mini-collocation panels to help learners produce more natural English, and common mistake boxes that highlight common errors to avoid when communicating in English.
