1st Conjugation: Verbs ending in -er (e.g., parler, chanter, manger)
2nd Conjugation: Verbs ending in -ir (e.g., finir, choisir, dormir)
3rd Conjugation: Verbs ending in -re (e.g., prendre, faire, écrire)
However, it's important to note that:
* This system is a simplification. Many irregular verbs exist in each conjugation and behave differently.
* Some verbs change their stem vowel during conjugation, even within the same conjugation. For example, "je parle" (1st conjugation) but "nous parlons".
* There are some verbs that don't fit neatly into these categories. For example, "aller" (to go) and "avoir" (to have) are considered irregular verbs with their own unique patterns.
Therefore, while the three conjugations are a good starting point, it's crucial to understand the individual behavior of each verb and learn its specific conjugation pattern.
