Here's what you might be thinking of:
* Verb Conjugations: French verbs are conjugated into various tenses and moods. However, these are not grouped based on infinitive forms. All verbs, regardless of their infinitive ending, follow the same conjugation rules within a particular tense/mood.
* Verb Classes: French verbs can be categorized into three classes based on their stem vowel changes:
* Regular verbs: These verbs follow predictable conjugation patterns.
* Irregular verbs: These verbs have irregular forms in certain tenses.
* Defective verbs: These verbs lack some tenses or forms.
However, these categories are not defined by the infinitive forms themselves. The infinitive is simply the base form of the verb, from which all other tenses and moods are derived.
Therefore, it's inaccurate to talk about "groups of infinitives" in French. There is no specific classification of infinitives based on their form or conjugation patterns.
If you can clarify your question, I might be able to give you a more precise answer.
