The Oxford Advanced Learner's Dictionary gives more help and more support than any other dictionary at this level. It focuses on learners' need to understand and use words correctly, and to develop their core language skills.
This tenth edition includes many new features. For written skills, the Oxford iWriter is an interactive tutor to help students plan, write, and check their written work; while the Oxford Writing Tutor is a 32-page practical guide to improving writing skills.
