Overview
Overview
what if and when this happens. It's an essential tool for C1 learners aiming for fluency and a deeper understanding of Portuguese grammar.se (if) and quando (when). By understanding its role in expressing future events that are contingent on other actions or circumstances, you'll be able to construct more accurate and natural-sounding sentences.How This Grammar Works
se (if) and quando (when). The formation typically involves taking the third-person plural of the preterite perfect indicative (e.g., eles falaram, eles comeram, eles partiram), removing the -am ending, and adding the appropriate future subjunctive endings: «-r» for eu, -res for tu, «-r» for ele/ela/você, -rmos for «nós,» -rem for eles/elas/vocês.For example, from
falaram, we get eu falar, tu falares, ele falar, nós falarmos, eles falarem.Se eu tiver tempo, irei à festa(If I have time, I will go to the party). Here,
tiver (from ter - to have) is in the future subjunctive, indicating that going to the party is conditional on having time.Quando ele chegar, avisaremos você(When he arrives, we will let you know).
Chegar (to arrive) is in the future subjunctive because the act of notifying someone is dependent on his arrival, which is a future, uncertain event. This tense is crucial for expressing cause and effect, plans, and predictions that are not yet guaranteed.
Common Mistakes
- 1✗ Wrong:
Se eu vou amanhã, você vem?
Se eu for amanhã, você vem?
se (if) introduces a hypothetical or conditional future event, which requires the future subjunctive (for from ir - to go). The future indicative (vou) implies a certainty of going, which contradicts the conditional nature introduced by se.- 1✗ Wrong:
Quando você vai terminar o trabalho, me diga.
Quando você terminar o trabalho, me diga.
quando (when), when referring to a future event that hasn't happened yet, triggers the future subjunctive. Vai terminar is the future indicative. Terminar is the correct future subjunctive form, indicating that the action of telling will happen *after* the work is finished, a future, contingent event.

Quick FAQ
Can the future subjunctive be used with depois que (after)?
Yes, depois que often triggers the future subjunctive when referring to a future event that will happen after another future event. For example,
Depois que eu comer, vou estudar.(After I eat, I will study.)
Is the future subjunctive always used with se and quando?
Not always. Se can also be followed by the imperfect subjunctive for past hypothetical situations (e.g.,
