Auto-envoyer 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 »:
« auto-envoie-t-elle ? »,
« auto-envoya-t-elle ? »,
« auto-enverra-t-elle ? »,
« a-t-elle auto-envoyé ? »,
« aura-t-elle auto-envoyé ? ».
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 »:
« auto-envoyé-je ? ». Note that with the
« é » at the first person of present indicative, the transformation of
« y » in
« i » is no longer necessary.
Finally, the interrogative form does not exist in subjunctive and imperative.
