How to Use “Ter” in Portuguese for Possession, Age, and Obligation

Introduction

Ter is one of the most essential verbs in Brazilian Portuguese. It can express possession, age, and obligation, and it appears in many everyday sentences. This article explains how to use ter in these three common functions with clear rules, conjugations, and natural examples for beginner to intermediate learners.

Overview: Why Ter Matters

Ter is irregular and multifunctional, so learning it early gives learners the ability to say who owns what, how old people are, and what must be done. While English often uses have, be, or must, Portuguese uses ter in specific ways that differ from literal English translations. Understanding those differences improves fluency and comprehension.

Basic Conjugation of Ter

Before diving into uses, here are the present and past forms you will see most often. Memorize these for everyday conversation.

Present:

eu tenho
tu tens
ele/ela/você tem
nós temos
vocês/eles/elas têm

Preterite (simple past):

eu tive
tu tiveste
ele/ela/você teve
nós tivemos
vocês/eles/elas tiveram

Imperfect (past ongoing):

eu tinha
tu tinhas
ele/ela/você tinha
nós tínhamos
vocês/eles/elas tinham

Future (simple):

eu terei
tu terás
ele/ela/você terá
nós teremos
vocês/eles/elas terão

Using Ter for Possession

One of the most direct uses of ter is to express possession, similar to English have. The structure is simple: subject + ter + object.

Examples:

Eu tenho um carro.
Ela tem uma casa em São Paulo.
Nós temos dois cachorros.

Note the placement of articles and numbers, which follow normal noun rules in Portuguese. For negative sentences, place não before the verb: Eu não tenho dinheiro.

Possession with People and Relationships

When talking about family or relationships, ter is common in conversational Brazilian Portuguese. It often replaces possessive adjectives in casual speech, though both are correct.

Examples:

Eu tenho três irmãos. (I have three siblings.)
Ele tem muita sorte com os amigos. (He has a lot of luck with friends.)

You can also use possessive adjectives for emphasis or formality: Meu irmão é médico versus Eu tenho um irmão médico.

Possession with Objects and Abstract Nouns

Ter works perfectly with both concrete and abstract nouns: objects, time, opportunities, and problems.

Examples:

Ela tem tempo hoje?
Tenho uma ideia boa.
Eles têm muitos problemas para resolver.

Using Ter to Express Age

In Portuguese, age is expressed with ter, not with the verb to be as in English. The structure is: subject + ter + number + anos.

Examples:

Eu tenho 25 anos.
Como você tem? (Informal ask for age; Note: a more formal phrase is Qual é a sua idade?)
Meu avô tem 80 anos.

When talking about children, it is common and natural to use months for babies: Ela tem cinco meses.

Negative and Past Forms for Age

To say someone was a certain age in the past, use the imperfect tense tinha: Quando nos conhecemos, eu tinha 20 anos. For negation: Ele não tem 18 anos, so the sentence denies the person is 18 now.

Using Ter for Obligation

Portuguese uses the construction ter de or ter que + infinitive to express obligation, similar to must or have to. Both forms are widely used in Brazil, though ter que is more colloquial and ter de slightly more formal or literary. The structure: subject + ter + de/que + infinitive verb.

Examples:

Eu tenho que estudar para a prova.
Ele tem de trabalhar amanhã cedo.
Nós temos que sair agora.

In spoken Brazilian Portuguese, contraction and reduced pronunciation are common, but the grammar remains the same. You can also use dever for obligation; dever is often more formal or stronger: Eu devo estudar mais.

Different Nuances: ter que vs ter de vs dever

Ter que is the most common in daily speech for obligations and plans. Ter de sounds more correct in written or formal contexts. Dever can express moral obligation or stronger necessity. Compare:

Eu tenho que pagar a conta. (I have to pay the bill.)
Eu tenho de pagar a conta. (Same meaning, slightly more formal.)
Eu devo pagar a conta. (I ought to / I should / I must pay the bill.)

Negative and Question Forms

Negatives put não before ter. For questions, invert intonation or use a question word. Examples show how possession, age, and obligation change in negative and interrogative forms.

Possession negative and question:

Eu não tenho tempo.
Você tem um mapa?

Age negative and question:

Ela não tem 18 anos.
Quantos anos você tem?

Obligation negative and question:

Eu não tenho que trabalhar amanhã.
Você tem que ir ao banco hoje?

Common Idiomatic Expressions with Ter

Ter appears in many idioms. Learning these will boost comprehension and make your speech more natural. Here are a few frequently used ones in Brazil.

ter saudade de (to miss someone or something): Eu tenho saudade da minha família.
ter razão (to be right): Você tem razão.
ter vontade de (to feel like doing something): Ela tem vontade de viajar.
ter cuidado (to be careful): Tenha cuidado ao atravessar a rua. Note the imperative form tenha.

These expressions often use ter in ways that do not translate literally into English, so memorize them as phrases.

Imperatives and Polite Requests

To give a command or a request politely, use imperative forms of ter when needed in expressions like Tenha calma or Tenha paciência. For negative commands, use não + the present subjunctive: Não tenhas or Não tenha, depending on register. In Brazil, the polite imperative for você is the present subjunctive form: Tenha paciência, por favor.

Practical Tips and Common Mistakes

1. Remember age uses ter, not ser. Saying Eu sou 25 anos is incorrect; use Eu tenho 25 anos.
2. Use ter de or ter que + infinitive for obligations rather than trying to translate must literally.
3. Mind irregular conjugations, especially in the preterite tive and imperfect tinha; these appear frequently in stories and descriptions.
4. In spoken Portuguese, subject pronouns are often dropped because the verb form shows the subject, but include pronouns to emphasize or for clarity: Tenho fome versus Eu tenho fome.
5. With adjectives that describe states tied to possession, Brazilians sometimes prefer ter expressions: Ele tem medo (He is afraid) versus Ele está com medo. Both are used, but Ele tem medo is idiomatic and common.

Cultural Notes

Using ter in polite requests and idioms reflects Brazilian conversational style. For example, when offering help you might say Precisa de ajuda? rather than Tenho? which sounds odd. Also, the phrase Minha casa é sua casa uses ser and possessive structure differently; Brazilians use both ter and possessive adjectives, depending on tone and formality.

Putting It All Together: Example Paragraphs

Conversation example showing all three uses:

— Olá, tudo bem?
— Tudo. Eu tenho um compromisso hoje e tenho que sair cedo. Além disso, meu filho tem sete anos e eu tenho que buscá-lo na escola. Você tem tempo para tomar um café amanhã?

Explanation: The first tenho expresses possession of a commitment, the second shows obligation, the third indicates the child’s age, and the last tem asks about availability (possession of time).

Advanced Tip: Combining Ter with Other Verbs

You will encounter constructions where ter pairs with compound forms or gerunds to express continuous states or completed actions in colloquial speech. For example, Ter + past participle can indicate possession of an experience: Eu tenho vivido bem ultimamente. Use these forms carefully and listen to native speakers to get natural rhythms and contexts.

Conclusion

Mastering ter unlocks basic conversations about possession, age, and obligation in Brazilian Portuguese. Learn the core conjugations, practice using ter with nouns and infinitives, and pay attention to common idioms. With these tools you will understand and express everyday ideas more naturally and confidently.
