The Longman Active Study Dictionary is designed for secondary schools. It uses the world-famous 2000-word Longman Defining Vocabulary to keep definitions accessible for intermediate learners. The dictionary includes thousands of examples, based on the British National Corpus and the Longman American Corpus, and features 16 colour pages with vocabulary exercises. It also includes usage notes and study pages to aid classroom practice or self-study, with a built-in workbook.
