What it actually is

Definitions are constrained to a controlled defining vocabulary, so you never need a second dictionary to understand the first one, and each headword carries a CEFR tag telling you whether it is worth learning yet, alongside British and American audio, grammar patterns and collocations. The free site covers the full Advanced Learner's Dictionary. It is monolingual by design, which is right for intermediate learners and off-putting for absolute beginners, and the ads and app upsells on the free site are noticeable.
