'Excellent book. The chapters put together and systematise a lot of material that is often taught in an anecdotal or haphazard sort of way, if at all. Students will learn a great deal from the book and have their confidence in using Spanish considerably boosted as a result.' - Jonathan Thacker, Merton College, University of Oxford, UK

'An invaluable, highly original and methodically sound approach to correcting and eliminating common, yet difficult-to-eliminate errors.' - Manuel Delgado, Bucknell University, USA
