An invaluable resource helping teachers at all levels of experience to develop their understanding of English grammar. Grammar for English Language Teachers is designed to help practising and trainee teachers to develop their knowledge of English grammar systems. It encourages teachers to appreciate factors that affect grammatical choices, and evaluates the \`rules of thumb\` presented to learners in course materials. Consolidation exercises provide an opportunity for teachers to test these rules against real language use and to evaluate classroom and reference materials.
