Portuguese Verb Conjugation — A Beginner's Guide

Portuguese verb conjugation can look intimidating — dozens of tenses, irregular forms, three verb groups. But here's the truth: you only need three tenses to hold a conversation, and the patterns are more regular than they first appear. This guide covers everything a beginner needs, nothing they don't.

The Three Verb Groups

Every Portuguese verb ends in -AR, -ER, or -IR. This ending tells you which conjugation pattern to follow. The good news: -AR verbs are by far the most common, and all three groups follow predictable patterns for regular verbs.

To conjugate a regular verb, you remove the ending (-ar, -er, -ir) to get the stem, then add the appropriate ending for the tense and person.

Present Tense — The Starting Point

This is where everyone begins. The present tense covers what you do, what you're doing, and general truths.

Notice that the eu form always ends in -o across all three groups. And the nós form always keeps the original vowel from the infinitive (a, e, i). These patterns make regular verbs very predictable.

Pretérito Perfeito — Simple Past

This is the second tense to learn. It covers completed past actions — "I spoke," "she ate," "they left."

Note that the nós form is identical to the present tense for -AR and -IR verbs. Context makes it clear which tense is meant — "Nós falamos português" could be "we speak" or "we spoke" depending on the conversation.

Pretérito Imperfeito — Imperfect Past

The third essential tense. It describes ongoing or habitual past actions — "I used to speak," "she was eating," "they always left early."

The imperfeito is beautifully regular — almost no verbs are irregular in this tense. And notice that -ER and -IR verbs share the same endings. Less to memorise.

The Future Shortcut

Here's something textbooks often overcomplicate: Brazilians almost never use the formal future tense in speech. Instead, they use ir + infinitive — exactly like "going to" in English.

Just conjugate ir in the present tense (eu vou, você vai, nós vamos, eles vão) and add any infinitive after it. You now have the future tense without learning a single new conjugation pattern.

The Irregular Verbs You Can't Avoid

There are about 10 verbs that are irregular in the present tense and appear in almost every conversation. These need to be memorised individually:

What to Learn When

Week 1–4: Present tense of regular verbs + the 10 irregulars above. This alone gets you through basic conversation.

Month 2–3: Pretérito perfeito (simple past) for telling stories and describing events. Plus the ir + infinitive future — essentially free.

Month 3–4: Pretérito imperfeito for describing past habits and background context. At this point, you can express almost anything in everyday conversation.

Later: Conditional (I would...), subjunctive (that I be...), and formal future (I shall...). Important eventually, but not urgent. Get the first three tenses solid before adding more.
