French irregular verbs are verbs that do not follow the standard conjugation patterns of regular -er, -ir, or -re verbs. Their forms can change unpredictably, especially in the present tense. Mastering irregular verbs is essential for fluency, as many commonly used verbs are irregular.
The main irregular verbs include *être*, *avoir*, *aller*, and *faire*.

Characteristics of Irregular Verbs

Irregular verbs often undergo stem changes, unique endings, or both. Some change their stem vowels (stem-changing verbs), while others use entirely unique forms for certain pronouns.
