Questions & Answers about Se o valor não aparecer no extrato, eu vou ligar para o banco amanhã.

Why is aparecer used instead of aparece?

Because after se when Portuguese talks about a possible future condition, it usually uses the future subjunctive.

So:

• Se o valor não aparecer... = If the amount doesn’t appear / if the amount should not appear...

For many regular verbs, the future subjunctive looks exactly like the infinitive:

• aparecer → future subjunctive aparecer
• falar → falar
• comer → comer

That is why it may look like the infinitive, but here it is actually a verb form used in a conditional clause.

Compare:

• Se ele aparecer, me avise. = If he shows up, let me know.
• Quando o valor aparecer, eu aviso. = When the amount appears, I’ll let you know.

This is a very important pattern in Portuguese.

What does se mean here?

Here, se means if.

It introduces a condition:

• Se o valor não aparecer no extrato... = If the amount doesn’t appear on the statement...

Be careful: se can have other uses in Portuguese, but in this sentence it is simply the conjunction if.
