First and foremost, I should like to acknowledge my debt of gratitude to Patricia López Iglesias, whose support and advice, unstintingly given, have been invaluable in the preparation of the fourth edition of Practising Spanish Grammar. Thanks also go to Laura Sandford and Rosie McEwan of Routledge for bringing the book to print.
This edition has been fully revised so that it follows more closely the general order of A New Reference Grammar of Modern Spanish by John Butt, Carmen Benjamin, and Antonia Moreira-Rodríguez (BB&M), and the references given for each exercise relate to the sixth edition of that book. New exercises have also been incorporated into the text to provide further practice of points of Spanish grammar.
