Portuguese Verb System Overview

Portuguese verbs are the heartbeat of the language. A single verb form can tell you who is acting, when the action takes place, whether it is real or hypothetical, and how it relates to other events in time. This richness is what allows Portuguese speakers to drop subject pronouns more often than not -- the verb ending already says it all. This page is your high-level map of the entire verb system, with links to deeper pages for each topic.

The three verb classes

Every Portuguese infinitive ends in one of three suffixes: -ar, -er, or -ir. These define the three conjugation classes, and each class follows its own set of endings.

The -ar class is by far the largest and most productive -- nearly all new verbs entering the language take this ending. The -er and -ir classes are smaller but contain many essential everyday verbs like ter (to have), ser (to be), ir (to go), and vir (to come). See The Three Verb Classes for full details.

Conjugation: stem plus ending

To conjugate a verb, you remove the infinitive ending (-ar, -er, or -ir) to find the stem, then add a new ending that encodes the subject, the tense, and the mood.

Because the verb ending already identifies the subject, European Portuguese routinely drops subject pronouns. Falo on its own means "I speak" -- there is no need to say eu. See How Verb Conjugation Works for a complete walkthrough.

Subject pronouns

Although pronouns are often omitted, knowing them is essential for understanding verb tables. European Portuguese distinguishes between informal tu and formal você, plus the very formal o senhor / a senhora.

Note that vós is archaic in standard European Portuguese but still appears in some northern dialects and in liturgical language. In everyday speech, vocês has replaced it entirely. See Subject Pronouns for more.

The three moods

Portuguese has three moods, each with its own set of tenses:

The indicative is the mood of what is. The subjunctive is the mood of what might be, should be, or is hoped for. The imperative is the mood of direct commands. Portuguese uses the subjunctive heavily in everyday speech -- far more than English does. Read more in Indicative, Subjunctive, and Imperative Moods.

Portuguese also preserves a future subjunctive that is actively used in daily speech, unlike in Spanish where it has nearly disappeared. You will encounter it in quando (when) and se (if) clauses referring to future possibilities.

Simple and compound tenses

Each mood contains both simple tenses (a single conjugated word) and compound tenses (a form of the auxiliary ter plus a past participle).

Between simple and compound forms across the indicative and subjunctive, Portuguese has around 18 distinct tense-mood combinations for finite verbs. Many share patterns, so the system is more learnable than it first appears. The full inventory is covered in Overview of All Tenses.

Non-finite forms

Non-finite forms do not carry a subject marker. Portuguese has three, just like other Romance languages -- but with a twist.

The twist is the personal infinitive (infinitivo pessoal), a feature virtually unique to Portuguese among the world's languages. It is an infinitive that conjugates for person, allowing you to give the infinitive its own subject -- something no other major Romance language can do.

In the example above, falarmos is the personal infinitive of falar conjugated for nós (we). This form often replaces the subjunctive and makes complex sentences clearer. See The Personal Infinitive for a dedicated page on this remarkable feature.

Regular and irregular verbs

Most Portuguese verbs follow the predictable pattern of their class -- they are regular. A significant minority are irregular, with stem changes, spelling adjustments, or entirely unpredictable forms. As in all Romance languages, the most common verbs tend to be the most irregular: ser (to be), ir (to go), ter (to have), fazer (to do/make), and dizer (to say).

The good news is that Portuguese irregularities follow families. Verbs like ter, vir, manter, and intervir share patterns. Learn one, and you have a head start on the others.

Reflexive verbs

Reflexive verbs carry a pronoun that refers back to the subject. They are marked by the pronoun -se attached to the infinitive: levantar-se (to get up), vestir-se (to get dressed), deitar-se (to lie down).

Reflexive verbs are far more common in Portuguese than in English. Many everyday actions -- washing, sitting down, feeling an emotion -- use reflexive forms. See Reflexive Verbs for the full picture.

Three verbs for "to be": ser, estar, and ficar

Where English has one verb "to be," Portuguese has three: ser, estar, and ficar. Each covers a different aspect of "being."

• Ser expresses identity, origin, and permanent characteristics: Sou português. (I am Portuguese.)
• Estar expresses states, locations, and temporary conditions: Estou cansado. (I am tired.)
• Ficar expresses becoming, remaining, or being located: Fico contente. (I become happy.) / O banco fica ali. (The bank is over there.)

Learning when to use each is one of the central challenges of Portuguese, and the subject has its own dedicated section. See Ser, Estar, and Ficar.

The progressive: estar a + infinitive

To express an action in progress, European Portuguese uses estar a + infinitive -- different from Brazilian Portuguese, which uses estar + gerund.

This construction is one of the clearest markers of European Portuguese and something you will use from your very first conversations. See Periphrastic Constructions for more verbal phrases of this type.
