Excellent.

Great reference

This is the book that took me from beginner to intermediate. Priceless. It does demand some facility with gramatical terms, but that isn't too surprising, is it?

"A New Reference Grammar of Modern Spanish has established itself as the standard English-language reference grammar for the Spanish language. It provides teachers, students, and others interested in the Spanish language with a comprehensive, accessible, and jargon-free guide to the forms and structures of Spanish as it is currently spoken and written in Spain and in Latin America."--BOOK JACKET.
