Grammar Rule in 30 Seconds

Irregular verbs in the future tense use special stems, but they all share the same standard future endings.

  • Identify the irregular stem (e.g., 'ser-' for être).
  • Add the standard endings: -ai, -as, -a, -ons, -ez, -ont.

Irregular Stem + (-ai, -as, -a, -ons, -ez, -ont) = Future Tense

A Regra do 'R'

Todo radical do Futur Simple TEM que terminar em 'r'. Se você não ouvir um 'r', não é futuro! Je ferai (com 'r'), não je faireai (sem 'r').
⚠️

A Armadilha do 'Vouloir'/'Voir'

Cuidado pra não confundir je voudrai (eu vou querer) com je verrai (eu vou ver). Pensa que voudrai tem um 'd' de 'Desejo'!
💡

Terminações do 'Avoir'

Repara que as terminações do futuro são quase iguais às do presente do verbo 'avoir' (ai, as, a, ons, ez, ont). Fica fácil de lembrar! "J'aurai«, »Tu auras".

Smart Tips

Most -oir verbs have a stem ending in -rr.

Je pouvoirai Je pourrai

The stem is always 'ser-'.

Je êtreai Je serai

The stem is always 'aur-'.

J'avoirai J'aurai

The stem is always 'fer-'.

Je faireai Je ferai

Pronúncia

IPA: /e/

Final -ai

Pronounced like 'é'.

IPA: /ɔ̃/

Final -ont

The 't' is silent.
