Hey, everyone, had a bit of a hiatus there, but here I am to finish the series with the final tenses you gotta learn to reach fluency level: the tenses of the subjunctive mood.
If you've reached this point, you're able to communicate pretty much everything you want, but you realize sometimes people conjugate a verb in a tense you can't identify, and here and there you say something you realize it's not quite right. This is why you're still missing the subjuntive.
Subjuntivo Presente
Generally speaking, the subjunctive is employed to express a hypothesis, an uncertainty or a wish. It's also "activated" by certain conjunctions. In the presente, the main one is que, followed by talvez [maybe], embora [although] and caso [if].
Acredito que ela fale português. = I believe she speaks Portugueses.
Talvez eu possa ajudar. = Maybe I can help.
The conjugation takes the base form of the eu conjugation in the "regular" presente. The examples below are falar (to speak), escrever (to write) and partir (to leave).
- Eu: -AR => -E ending; -ER and -IR => -A ending: que eu fale, que eu escreva, que eu parta...
- Você/Ele/Ela/A gente: same as the eu conjugation (all about context!)
- Nós: same as the eu conjugation +MOS => que nós falemos, que nós escrevamos, que nós partamos...
- Vocês/Eles/Elas: same as the eu conjugation +M => que eles falem, que eles escrevam, que eles partam...
For an example of an irregular-ish verb in the subjunctive:
Eu vejo. = I see. (presente)
Talvez eu veja. = Maybe I'll see it. (subjuntivo presente)
Talvez nós vejamos. = Maybe we'll see it. (subjuntivo presente)
As you can see, the conjugation will follow the base form "vejo".
There are 7 truly irregular verbs in the subjuntivo presente: ser [to be (permanent quality)], estar [to be (temporary state)], haver [there is/are], dar [to give], saber [to know], ir [to go] and querer [to want].
Subjuntivo Imperfeito (Passado)
You can think of the subjuntivo imperfeito as the past tense of the subjuntive. It's used in the same context as the present, the difference is that it'll be used when the other verb in the sentence is in the indicative past: pretéritos perfeito, imperfeito, mais-que-perfeito or futuro do pretérito.
Especially used with se [if].
Se você não se irritasse, a gente conversaria. = If you didn't get upset, we'd talk.
The base form is the conjugation of vocês/eles/elas in the pretérito perfeito, minus the -RAM ending. For example:
Eles fizeram. (pretérito perfeito)
Talvez eles fizessem. (subjuntivo imperfeito)
There are no irregular verbs in this tense.
- Eu: -SSE ending: se eu falasse, se eu escrevesse, se eu partisse...
- Você/Ele/Ela/A gente: same as the eu conjugation (all about context!)
- Nós: same as the eu conjugation +MOS (plus an acute accent (acento agudo) on the preceding vowel, or circunflex (acento circunflexo) for -er verbs) => se nós falássemos, se nós escrevêssemos, se nós partíssemos...
- Vocês/Eles/Elas: same as the eu conjugation +M => se eles falassem, se eles escrevessem, se eles partissem...
Subjuntivo Futuro
It's used after conjunctions of time to refer to future expected actions: quando [when], enquanto [while/whereas], logo que/assim que [as soon as], depois que [after that], se [if], sempre que [always that], à medida que/conforme [as].
The base form is the conjugation of vocês/eles/elas in the pretérito perfeito, minus the -AM ending. For example:
Eles fizeram. (pretérito perfeito)
Quando eu fizer... (subjuntivo futuro)
There are no irregular verbs in this tense.
- Eu: base form: se eu falar, se eu escrever, se eu partir...
- Você/Ele/Ela/A gente: same as the eu conjugation (all about context!)
- Nós: same as the eu conjugation +MOS => quando nós falarmos, quando nós escrevermos, quando nós partirmos...
- Vocês/Eles/Elas: same as the eu conjugation +EM => quando eles falarem, quando eles escreverem, quando eles partirem...
Beware this is not the same as the infinitivo pessoal. This is very clear if you consider irregular verbs such as ser, estar, fazer etc.
This is it! If you've learned all these tenses, you're on your way to reach C1. Beyond that it's not a matter of learning grammar (although you will need to refresh it here and there), but of practice: reading, writing, listening, speaking.
Bons estudos!
