Common Auxiliary Verbs in Portuguese

LEVEL a2 TOPIC Verbs auxiliary verbs

Have you ever struggled to determine whether an auxiliary verb should be followed by ‘a’ or not?

For example, many students say Vou a comprar leite, but in Portuguese, the auxiliary verb ir is not followed by a preposition. The correct form is Vou comprar leite.

Typically, auxiliary verbs are conjugated in the Present or Past tense and followed by the main verb in the Infinitive form.* However, there are some variations to this pattern.

Some auxiliary verbs require a or de before the main verb, while others connect directly without any preposition.

Let’s explore some of the most commonly used auxiliary verbs in Portuguese and identify the structures they typically follow.

* Auxiliary verbs like ter, ser, and estar are also used to form compound tenses (perfect tenses) and the passive voice. In these cases, they are followed by the main verb in the Past Participle form rather than the Infinitive. However, these uses are not covered in this article.

What learners say

I love the mix of formats. The listening pieces, short reads, exercises, and idioms cover different angles, so I don't get stuck doing the same thing. It keeps me coming back.

~ Olivia ~

It doesn’t feel like studying in the boring sense. The tone is light, but the practice is solid, and I’ve noticed I can put sentences together more easily.

~ Giulia ~

Everything feels well put together. I'll listen to something at my level, check a quick explanation when I'm confused, and then do a practice exercise. Everything I need is in one place and easy to find.

~ Liam ~

Portuguese used to feel messy, like I was putting in effort but not getting results. With Portuguesepedia, I can focus on what I actually need, and I’ve started noticing real improvement week by week.

~ Ebba ~

Something clicked after a few weeks. Real Portuguese started making more sense — not just on paper, but when I'm actually listening. I hadn't felt that kind of progress before.

~ Maria ~

I’d been trying to learn Portuguese for years, but I never felt confident using it. Textbooks were too much, and speaking classes made me freeze. With Portuguesepedia, things finally started to make sense.
