conjugation rules and endings for the first group verbs.
However, although the terminations are perfectly regular, stem can be irregular and have numerous variations.
Bêtifier is conjugated the same way that verbs that end in :
-ier.
Bêtifier verb is conjugated in interrogative form. For sound reasons, an euphonious
« t » is added to the pronoun of the third person:
« il »,
« elle »,
« on »,
« ils »,
« elles » except when the verb ends with
« t » or
« d »:
« bêtifie-t-il ">« aura-t-il bêtifié ? ».
Always in interrogative form, and always for sound reasons, an accent appears in first person present indicative tense when the verb ends with
« e ». An euphonious
« e » is replaced by
« é »:
« bêtifié-je ? ».
Finally, the interrogative form does not exist in subjunctive and imperative.
