conjugation rules and endings for the first group verbs.
However, although the terminations are perfectly regular, stem can be irregular and have numerous variations.
Corroyer is conjugated the same way that verbs that end in :
-yer. Verbs ending in
-yer may transform the stem letter
« y » in
« i » before a silent endings.
It is the case for verbs ending in
-oyer and
-uyer (other than envoyer and renvoyer). They replace the
« y » with an
« i » before an unpronounced
« e », turning the preceding syllable in a diphthong. The prototypical verbs are broyer, noyer, ennuyer.
Corroyer 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 »:
« corroie-t-il ">« aura-t-il corroyé ? ».
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 »:
« corroyé-je ">« i » is no longer necessary.
Finally, the interrogative form does not exist in subjunctive and imperative.
