The book aims to help children improve their wordpower, by increasing their vocabulary and making sure they use words correctly and imaginatively. Areas covered include adjectives, describing people, collective nouns, onomatopoeic words, commonly confused pairs, avoiding over-used words - and much more. Vocabularly Repair Kit is livened up by the usual cast of humorous Repair Kit characters (Zelda, Colin and Steven), and the book also contains interactive elements such as quizzes and tests.
