Why verbs change: the basic idea
Portuguese verbs change their endings to show who is doing the action, when the action happens, and sometimes how it is happening. This is called conjugation. Unlike English, which often uses separate words like do/does or will, Brazilian Portuguese typically modifies the verb itself. Understanding this will help you read menus, fill out forms, and say simple sentences correctly.
Key terms
Conjugação – the process of changing a verb’s form to match subject and tense.
Tempo – tense, which shows when the action happens (present, past, future).
Pessoa – grammatical person, which indicates who performs the action (I, you, he/she, we, you plural, they).
Subjects and verb endings: the present tense
Start with the present tense, because beginners use it the most. In Portuguese, verbs in the infinitive end in -ar, -er, or -ir. Each group has its own endings for each person.
Example verbs: falar (to speak), comer (to eat), abrir (to open).
Present tense endings: a simple chart in practice
I speak: eu falo
You speak (informal): você / tu fala / fala
He/She speaks: ele/ela fala
We speak: nós falamos
You all speak (formal): vocês falam
They speak: eles/elas falam
I eat: eu como
You eat: você / tu come / come
We eat: nós comemos
They eat: eles comem
I open: eu abro
You open: você abre
We open: nós abrimos
They open: eles abrem
Why you see many different forms in simple sentences
In English a beginner sentence like I eat or She eats looks similar because English adds an auxiliary or little ending. In Portuguese the verb itself changes more. For example, the phrase Eu como pão (I eat bread) uses como, but Você come pão uses come. Both look like different words, but they come from the same verb comer.
Practical beginner examples
At a café: Você quer café? (Do you want coffee?)
Here quer is the third person form used with você for want, from querer.
On a menu: Prato do dia: peixe grelhado
The participle grelhado shows how the fish is prepared, matching common menu language.
On a schedule: O ônibus chega às 8h. (The bus arrives at 8.)
Here chega is present tense for ele/ela from chegar.
Subject pronouns: when they are optional
Subject pronouns like eu, você, ele often appear in beginner lessons but are not always needed in Portuguese. The verb ending usually tells you the subject. Beginners are encouraged to learn pronouns, but in real spoken Brazilian Portuguese, people often drop eu or ele because the verb form is clear.
Example without pronoun: Vou ao mercado. (I go / I’m going to the market.)
Example with pronoun: Eu vou ao mercado.
Tip for beginners
When writing or speaking your first sentences, include the pronoun to avoid mistakes. As you get more comfortable, you will start dropping it naturally.
Regular vs irregular verbs: what changes and what stays the same
Most verbs are regular and follow predictable patterns. Irregular verbs change stems or endings and must be memorized. Beginners should first focus on high-frequency regular verbs, then learn the most common irregulars.
Common regular verbs to practice: falar, comer, abrir, estudar (to study), trabalhar (to work).
Common irregular verbs: ser (to be), estar (to be temporary), ir (to go), ter (to have), fazer (to do/make).
Examples of irregular verbs in simple sentences
Eu sou estudante. (I am a student.) – from ser
Eu estou cansado. (I am tired.) – from estar
Eu vou ao banco. (I go / I’m going to the bank.) – from ir
Eu tenho uma pergunta. (I have a question.) – from ter
Past and future: simple beginner patterns
Beginners will meet two common past tenses: the pretérito perfeito (simple past) and the imperfect. Start with the pretérito perfeito to say completed actions.
Example with falar in the past: Eu falei com ela ontem. (I spoke with her yesterday.)
Example with comer in the past: Nós comemos no restaurante. (We ate at the restaurant.)
To talk about the future, a simple beginner option is the periphrastic construction using ir + infinitive, which behaves like English will be going to.
Eu vou estudar amanhã. (I will study tomorrow.)
Ele vai trabalhar hoje à noite. (He will work tonight.)
Practical vocabulary and phrases showing verb changes
Basic verbs and example uses you will encounter:
comprar – eu compro pão todos os dias. (to buy)
pagar – Você paga com cartão? (Do you pay with card?) (to pay)
abrir – A loja abre às 9h. (The store opens at 9.) (to open)
fechar – O supermercado fecha às 22h. (The supermarket closes at 10 pm.) (to close)
precisar – Eu preciso de ajuda. (I need help.) (to need)
Short dialogues for beginners
At a shop:
Vendedor: Olá, em que posso ajudar?
Cliente: Eu quero uma água, por favor.
Vendedor: Tudo bem, são 5 reais.
On the phone:
Amigo: Você vai ao cinema hoje?
Você: Sim, eu vou às 20h.
Common beginner mistakes and how to avoid them
Mistake 1: Using the infinitive instead of a conjugated form. Beginners sometimes say eu falar instead of eu falo. Fix: learn the present endings and practice with I, you, he forms.
Mistake 2: Confusing ser and estar. Use ser for permanent identity and estar for temporary states. Eg: Eu sou professor vs Eu estou cansado.
Mistake 3: Overusing pronouns. It is okay to drop subject pronouns once you know verb endings, but beginners should keep them while learning.
Practical drill suggestions
Practice 1: Take one regular verb and make six present-tense sentences, one for each person. Say them out loud.
Practice 2: Create three short dialogues using high-frequency irregular verbs: ser, estar, ir, ter.
Practice 3: Read a simple sign or menu and identify every verb, then write who is doing the action and when it happens.
Why learning verb patterns pays off quickly
Understanding verb changes gives you the power to express time, ask questions, and understand signs and schedules. Early mastery of a few patterns and the most common irregular verbs allows beginners to form hundreds of practical sentences for travel, shopping, and daily life in Brazil.
Conclusion
Verb changes in Brazilian Portuguese are a way to show who does an action and when it happens. Learn present tense endings for -ar, -er, -ir verbs, study a handful of irregular verbs, and practice with short real-life sentences like Eu vou ao mercado and Ela chega às 9h. With targeted practice, these patterns will soon feel natural.
