* Different Classifications: There are various levels of "irregularity." Some verbs have just a slightly altered conjugation in certain tenses, while others are completely different throughout.
* Subtleties: There are also verbs that are considered "semi-irregular," meaning they follow a pattern but have some unpredictable changes.
* Regional Variations: French, like any language, has regional dialects and nuances, leading to slight variations in verb conjugation.
However, a general consensus is that there are around 100-150 irregular verbs in French that are commonly used.
It's more important to focus on learning the most frequent irregular verbs rather than trying to memorize a specific number. Many textbooks and online resources offer lists of the most important ones.
