This textbook gives an introduction to the grammar and punctuation of present-day Standard English in the context of their relevance to communication. Its up-to-date grammatical and punctuation content, rooted in national literacy strategies, is particularly relevant to Key Stages 3 and 4 (ages 11-16), but the book can be used also for, and by, older students. Its unique selling points include concise notes addressing a range of relevant usage points, a spotlight on the areas which writers tend to find troublesome and authentic examples helping to bring the content to life. The book aims primarily to improve students' communication skills (particularly written), to constitute an accessible reference source and to serve as an editing handbook.
