Blurbs English: Word Formation is an app for iPhone and iPad for intermediate-advanced learners of English. If you are studying for English exams (B2-C2), you will know that the word formation section of the exam is especially challenging. Even in day-to-day conversation, or writing an email, word formation can be the difference between miscommunication and fluency. Blurbs English: Word Formation is the first app in a series which concentrates on focused practice of English exam skills. Challenge yourself, practise every day, and pass those exams.
