What this is about
Portuguese has two futures. Since Lição 4 you've used the spoken one — vou viajar — and that covers about 90% of daily conversation. The futuro simples (viajarei) — a Brazilian grammar book calls it the futuro do presente — is the dressed-up future: newspapers, contracts, speeches, song lyrics, promises and solemn dreams. You need it to read Brazil and to write like an adult; you'll speak it mostly in fixed phrases such as será que…? and farei o meu melhor.
The formation — the whole infinitive + four endings
| eu morarei · você/ele morará · nós moraremos · eles morarão | -AR verbs |
| comerei · comerá · comeremos · comerão | -ER verbs — identical endings |
| abrirei · abrirá · abriremos · abrirão | -IR verbs — identical endings |
| serei · estarei · irei · terei · poderei | the usual troublemakers are REGULAR here |
The three rebels — fazer, dizer, trazer
| fazer → far-: farei, fará, faremos, farão | NOT fazerei |
| dizer → dir-: direi, dirá, diremos, dirão | NOT dizerei |
| trazer → trar-: trarei, trará, traremos, trarão | NOT trazerei |
When to use which future
| Vou viajar amanhã. | spoken plan — everyday life |
| Viajarei pelo mundo. | written / promise / dream |
| O presidente visitará o Brasil em maio. | news style |
| Eu te amarei para sempre. | a vow — vou te amar would sound like a schedule |
| Será que vai chover? · Será que ela gosta de mim? | será que = I wonder if… (spoken constantly) |
Exceptions & details
1 · The "probably" future. Brazilians use the futuro simples to guess about NOW: Serão umas três horas (it must be about three), Onde ela estará? (where can she be?).
2 · Formal service register. Será feito, senhora — "it will be done"; O senhor fará a gentileza de…? — hotel-desk politeness.
3 · Never after quando/se. "When I go" is quando eu for (future subjunctive, Lição 27) — never quando eu irei.
4 · Object pronouns in careful writing can split the verb (dir-lhe-ei) — you'll see it in old texts; nobody speaks it. Brazilians say vou dizer para ele.
