This book has not been written to compete either with school-textbooks, neither with SPANISH GRAMMAR books of 500 or 800 pages, aimed at University students and teachers. This is a work directed to students and/or teachers of Primary and Secondary schools who wish to have compiled in 1 volume the numerous RULES and EXCEPTIONS - concerning Morphology and Syntax - which are scattered along the more than eighty lessons that may include studies of Primary and Secondary courses. Due to the book format and number of pages this GRAMMAR provides EASY handling. The structure and summary tables will be EASY to understand and memorize. Because of its 40 pages about Special Difficulties, and its 33 models of IRREGULAR verbs, you had wished to have been able to consult it long ago. Its INDEX General 50 CLUES and Alphabetical will make searching EASY. The INDEX entitled 50 STEPS is for structuring the teaching in 50 progressive steps from minor to greater difficulty. The information given in the ANNEX about SPAIN will be also very useful for you all.
