Introduction to the Clé de l'orthographe des verbes français aux temps usuels
Verb forms constitute one of the major difficulties for students of French, a difficulty which has led to a plethora of methods and learning techniques, as well as a proliferation of reference works.

Most often the obvious concern to account for all dimensions of the verb system has led authors to conceive very learned works, but works that are often difficult to consult and hardly adapted to the needs of a French second-language classroom. Students who have questions about how to form a certain tense or how to spell it need a practical and simple answer. Thus the Clé de l'orthographe des verbes français aux temps usuels.
