Learning grammar is always a difficult task. It often becomes tedious to memorise long lists of verbs and tenses. We recommend that you use the "learn basic French" and "learn French by selecting a theme" lessons to begin. The grammar lessons should only be used as a revision and reference when confronted with a problem. Do not try to learn all of this by heart.
You can conjugate hundreds of regular French verbs by typing in the English translation of the French infinitive (the verb ending in er, -ir, or re) on the interactive Verb conjugation page.
