The purpose of the BonPatron Grammar Guide is to provide learners with key points to keep in mind when they are writing. The guide contains explanations of the main grammatical categories, grammatical rules, exceptions and grammatical errors to avoid. The objective of the guide is not to provide a "laundry list" of every imaginable detail of French grammar. Rather, it is to identify the key points learners need to master in order to avoid making errors in their written assignments. In brief, the guide is a valuable resource to help learners self-edit their compositions.
