The short answer
The future subjunctive appears after connectors such as quando and se when the event is still open in the future. Common forms include fizer (do), tiver (have), puder (be able), and vier (come).
Recognize common irregular forms
A useful way to recognize many irregular forms is to look at the third-person plural preterite and remove the final -am: fizeram → fizer, tiveram → tiver, puderam → puder, vieram → vier.
Quando você puder, me liga.
Call me when you can.
Se eu tiver tempo, vou passar aí.
If I have time, I’ll stop by.
Quando ele vier, a gente conversa.
When he comes, we’ll talk.
Use the same pattern with future plans and conditions
The result clause often uses the present or a form with ir + infinitive. The future meaning comes from the situation; you do not need to add a future ending to the verb after quando or se.
For regular verbs, the future subjunctive often resembles the infinitive, but these high-frequency irregular forms need to be learned on their own.
Se você fizer o pedido hoje, ele chega amanhã.
If you place the order today, it arrives tomorrow.
Assim que tivermos uma resposta, avisamos.
As soon as we have an answer, we’ll let you know.
Quando eu puder viajar, quero conhecer o Nordeste.
When I can travel, I want to visit the Northeast.
