MY BOOKS
Here is where my training in Linguistics and my experience teaching languages converge. Throughout my years of teaching, I saw many students struggling with grammar rules that were explained in their textbooks and that they were told to memorize. This way of learning was not really effective. So very early on, I began writing materials to clarify concepts and rules for my students or to present the grammatical system in a completely new way. This led me, over the years, to write the books I posted below, some of which were coauthored with Arie Vicente.

Have you ever had doubts on when to write e with accent in Spanish? or i with accent in Spanish? Why is Mario without accent, but María carries one? or when to use a with accent, or o with accent? Why is joven without accent, but jóvenes needs one?
You will find answers in The Written Accent Marks in Spanish.
And no, we don't need to memorize accented words, nor to remember what "aguda, llana, esdrújula y sobresdrújula" mean. The premise of this book is that there are no rules for writing the accent marks. There are, however, rules for speaking and placing the stress--oral emphasis given to certain syllables in speech. In this book you will find:
-
Explanations in English
-
Multiple examples in Spanish
-
Differences between Spanish and English
-
Exercises for practice
-
If you wish to delve deeper, look for boxes named “FOR MORE.”
Whether you are a Spanish learner or a teacher who wants to teach this topic in a simple way, this book is for you.
