This Spanish grammar workbook is designed primarily for students of Spanish Philology at the university level, but also for all others interested in widening their knowledge of Spanish grammar. The book assumes a good knowledge of Spanish (at a level of B2, C1, C2) and focuses on relatively difficult grammatical phenomena. It covers the entirety of Spanish grammar: the reader will find exercises on spelling, pronunciation, morphology, syntax, and even some questions related to vocabulary. Particular attention is paid to current standards (the book contains many exercises comparing the valid norms and incorrect usages) and phenomena that are particularly difficult for Czech students of Spanish.
