ter de en 30 secondes
- Expresses necessity or obligation.
- Equivalent to 'to have to' in English.
- Structure: conjugated 'ter' + 'de' + infinitive verb.
- Essential for daily communication.
- Core Meaning
- 'Ter de' is a fundamental verb phrase in Portuguese that conveys necessity or obligation. It directly translates to 'to have to' or 'to be obliged to' in English. It signifies that an action is required, either due to external circumstances, rules, or personal commitment. This phrase is incredibly common and essential for expressing everyday responsibilities and duties.
- When to Use It
- You will use 'ter de' in countless situations. It's used for daily routines: 'Eu tenho de acordar cedo.' (I have to wake up early.). It's used for work or school obligations: 'Nós temos de entregar o projeto até sexta-feira.' (We have to hand in the project by Friday.). It's also used for rules and laws: 'Os motoristas têm de usar cinto de segurança.' (Drivers have to use seatbelts.). In personal contexts, it expresses a strong need or a plan: 'Tenho de ir ao supermercado.' (I have to go to the supermarket.) or 'Temos de pensar numa solução.' (We have to think of a solution.). The phrase is versatile and adapts to many contexts, making it a cornerstone of practical Portuguese communication.
- Grammar Note
- 'Ter de' functions as a modal verb phrase. The verb 'ter' (to have) is conjugated according to the subject, and it is always followed by the preposition 'de' and then the infinitive of the main verb. For example, 'eu tenho de comer' (I have to eat), 'tu tens de comer' (you have to eat), 'ele/ela/você tem de comer' (he/she/you has/have to eat), 'nós temos de comer' (we have to eat), 'vós tendes de comer' (you all have to eat), 'eles/elas/vocês têm de comer' (they/you all have to eat). Understanding the conjugation of 'ter' is key to using this phrase correctly.
Eu tenho de estudar para o exame.
Eles têm de sair agora.
Você tem de terminar o trabalho hoje.
- Basic Structure
- The most common structure is: [Subject Pronoun] + ter (conjugated) + de + [Infinitive Verb]. For example, 'Eu tenho de comer' (I have to eat). The subject pronoun can often be omitted if it's clear from the verb conjugation.
- Expressing Daily Obligations
- 'Ter de' is perfect for describing routines and things you must do regularly. 'Eu tenho de ir à academia três vezes por semana.' (I have to go to the gym three times a week.). 'Ela tem de preparar o jantar todas as noites.' (She has to prepare dinner every night.). 'Nós temos de verificar o nosso email constantemente.' (We have to check our email constantly.).
- Talking About Work and Studies
- This phrase is indispensable when discussing professional or academic responsibilities. 'Os alunos têm de estudar para passar no exame.' (The students have to study to pass the exam.). 'Eu tenho de ligar para o cliente antes do fim do dia.' (I have to call the client before the end of the day.). 'Precisamos de pensar em novas estratégias; temos de inovar.' (We need to think of new strategies; we have to innovate.).
- Referring to Rules and Laws
- When discussing regulations or what is required by law, 'ter de' is the go-to phrase. 'Todos os cidadãos têm de pagar impostos.' (All citizens have to pay taxes.). 'É preciso ter de apresentar um documento de identificação.' (It is necessary to have to present an identification document.). 'Os carros têm de parar no semáforo vermelho.' (Cars have to stop at the red light.).
- Expressing Personal Needs or Plans
- You can also use it to talk about what you personally need or plan to do. 'Eu tenho de comprar pão para o pequeno-almoço.' (I have to buy bread for breakfast.). 'Temos de decidir onde vamos nas férias.' (We have to decide where we are going on vacation.). 'Ela tem de arranjar o carro antes da viagem.' (She has to fix the car before the trip.).
- Forming Questions
- To ask about obligations, you can invert the subject and verb or use question words. 'Tens de ir?' (Do you have to go?). 'O que temos de fazer agora?' (What do we have to do now?). 'Por que ele tem de sair tão cedo?' (Why does he have to leave so early?).
Nós temos de terminar este relatório até amanhã.
Ele tem de ligar para a mãe todos os domingos.
Vocês têm de seguir as instruções cuidadosamente.
- Everyday Conversations
- You'll hear 'ter de' constantly in casual chats among friends and family. Imagine someone planning their day: 'Hoje eu tenho de ir ao mercado e depois tenho de buscar as crianças na escola.' (Today I have to go to the market and then I have to pick up the children from school.). Or discussing chores: 'Nós temos de limpar a casa antes que os convidados cheguem.' (We have to clean the house before the guests arrive.). It's the natural way to express what needs to be done.
- Workplace and Professional Settings
- In professional environments, 'ter de' is used to outline responsibilities and deadlines. A manager might say to their team: 'Vocês têm de terminar esta apresentação até às cinco.' (You all have to finish this presentation by five.). An employee might report: 'Eu tenho de contactar o fornecedor para confirmar o pedido.' (I have to contact the supplier to confirm the order.). It's common in meetings, emails, and project discussions.
- Educational Institutions
- Teachers and professors frequently use 'ter de' when giving instructions or setting expectations. 'Os alunos têm de entregar os trabalhos a tempo.' (The students have to hand in their assignments on time.). 'É importante que todos tenham de ler o capítulo antes da aula.' (It's important that everyone has to read the chapter before class.). Students also use it to talk about their academic workload: 'Eu tenho de estudar muito para este exame.' (I have to study a lot for this exam.).
- Public Announcements and Instructions
- You'll encounter 'ter de' in public signage, announcements, and official instructions. For instance, on a bus: 'Os passageiros têm de validar o seu bilhete.' (Passengers have to validate their ticket.). In a museum: 'Os visitantes não têm de tocar nas obras de arte.' (Visitors do not have to touch the works of art.). Or during public health advisories: 'Todos têm de usar máscara em locais fechados.' (Everyone has to wear a mask in enclosed spaces.).
- Media and Entertainment
- News reports, documentaries, and even fictional dialogues will feature this phrase. A news anchor might report on a new regulation: 'O governo anunciou que as empresas terão de reduzir as emissões.' (The government announced that companies will have to reduce emissions.). In a movie, a character might say to another: 'Temos de sair daqui agora, não temos tempo a perder!' (We have to get out of here now, we don't have time to lose!).
No aeroporto, os passageiros têm de passar pela segurança.
A professora disse que nós temos de apresentar o trabalho na próxima semana.
Eu tenho de ir ao médico amanhã de manhã.
- Forgetting the 'de'
- One of the most frequent errors for learners is omitting the preposition 'de' after the conjugated verb 'ter'. This results in grammatically incorrect sentences. For example, saying 'Eu tenho comer' instead of 'Eu tenho de comer' is a common mistake. The 'de' is essential for linking 'ter' to the infinitive verb that expresses the action that must be done. It's like saying 'I have to eat' where 'to' is the necessary connector.
- Incorrect Conjugation of 'ter'
- 'Ter' is an irregular verb in Portuguese, and its conjugation can be tricky. Learners might use the wrong form of 'ter' for a particular subject. For instance, using 'Eu tem de ir' instead of the correct 'Eu tenho de ir'. Or confusing third-person singular and plural forms, like 'Nós tem de sair' instead of 'Nós temos de sair'. Mastering the conjugation of 'ter' is crucial for using 'ter de' accurately.
- Confusing with 'ter que'
- While 'ter de' and 'ter que' are often interchangeable and both mean 'to have to', there can be subtle differences in usage and regional preference. Some learners might overuse one or the other, or use them in contexts where one is more natural. In many situations, they are synonymous, but 'ter de' is sometimes perceived as slightly more formal or a stronger obligation than 'ter que', though this is not a strict rule and varies greatly.
- Using 'ter' alone
- Sometimes learners might try to use 'ter' alone to express obligation, which is incorrect. For example, 'Eu tenho ir' is not a valid construction in Portuguese for expressing necessity. The verb 'ter' on its own means 'to have' in the sense of possession, not obligation. The construction 'ter de' or 'ter que' is specifically for expressing 'to have to'.
- Overusing 'ter de' when 'dever' is more appropriate
- While 'ter de' expresses a strong obligation, the verb 'dever' also means 'to have to' or 'should', often implying a moral obligation or a strong recommendation. Learners might use 'ter de' in situations where 'dever' would sound more natural, or vice-versa. For instance, 'Eu tenho de ser gentil com os outros' (I have to be kind to others) is grammatically correct, but 'Eu devo ser gentil com os outros' might sound more natural as it implies a moral duty.
Incorrect: Eu tenho ir ao médico.
Correct: Eu tenho de ir ao médico.
Incorrect: Nós tem de estudar.
Correct: Nós temos de estudar.
Incorrect: Ele tem que comer agora.
Correct: Ele tem de comer agora. (or Ele tem que comer agora.)
- Ter que
- Meaning: To have to; to be obliged to.
Comparison: 'Ter que' is very similar to 'ter de' and is often used interchangeably in most contexts. Both express necessity or obligation. In Brazilian Portuguese, 'ter que' is generally more common in everyday speech than 'ter de'. In European Portuguese, 'ter de' might be slightly more prevalent in formal contexts, but both are widely understood and used.
Example: Eu tenho que estudar para o exame. (I have to study for the exam.)
Example: Nós temos que ir. (We have to go.) - Dever
- Meaning: Should; ought to; must.
Comparison: 'Dever' can express a strong obligation, similar to 'ter de', but it often carries a sense of moral duty, recommendation, or probability. When 'dever' is used to express a strong obligation (like 'must'), it can be synonymous with 'ter de' or 'ter que'. However, it's also used for advice ('You should...') or to express likelihood ('He must be tired.').
Example: Você deve estudar mais. (You should study more. / You must study more.)
Example: Os pais devem cuidar dos filhos. (Parents must take care of their children. - moral obligation) - Ser preciso
- Meaning: To be necessary.
Comparison: 'Ser preciso' is an impersonal expression that means 'it is necessary'. It conveys obligation or requirement, but it's structured differently. You don't conjugate 'ser' for a specific subject in the same way as 'ter de'. It's often followed by 'de' and the infinitive.
Example: É preciso apresentar um documento. (It is necessary to present a document.)
Example: É preciso seguir as regras. (It is necessary to follow the rules.) - Necessitar de
- Meaning: To need to.
Comparison: 'Necessitar de' implies a need rather than a strict obligation or duty. While needing to do something often leads to doing it, the focus is on the requirement or lack of something, not necessarily an external or moral imperative.
Example: Eu necessito de comprar comida. (I need to buy food.)
Example: Nós necessitamos de mais tempo. (We need more time.)
'Ter de' vs 'Ter que': Both are common for 'to have to'. 'Ter de' can sometimes feel slightly more formal, especially in European Portuguese.
'Dever' can mean 'must' but also 'should', implying advice or probability. 'Ter de' is more strictly about obligation.
'Ser preciso' is impersonal ('It is necessary to...') while 'ter de' is personal ('I have to...').
How Formal Is It?
Le savais-tu ?
The preposition 'de' in 'ter de' plays a crucial role in transforming the verb 'ter' (to have) from indicating possession into indicating obligation. This is a common grammatical development in Romance languages where prepositions help to create new verb phrases.
Guide de prononciation
- Pronouncing 'ter' with a closed 'e' sound as in 'there'.
- Not pronouncing the 'de' at all.
- Pronouncing 'de' as a hard 'd' sound.
- Confusing the 'r' sound in 'ter'.
Niveau de difficulté
The phrase itself is straightforward, but understanding its nuances and correct conjugation requires practice. Recognizing it in complex sentences can be a challenge for beginners.
Requires accurate conjugation of 'ter' and correct placement of 'de'. Common errors involve forgetting 'de' or conjugating 'ter' incorrectly.
Pronunciation needs practice, especially the unstressed 'de'. Fluency comes with regular use and correct conjugation.
Recognizing the phrase in spoken Portuguese can be difficult due to the unstressed nature of 'de' and the variety of verb conjugations.

InformalFacile à confondre
Both phrases express the same core meaning of obligation.
'Ter de' is generally considered slightly more formal and is more common in European Portuguese, while 'ter que' is more prevalent in Brazilian Portuguese and can sometimes feel more colloquial. However, in many contexts, they are completely interchangeable and understood by all speakers.
Eu <mark class='bg-blue-200 dark:bg-blue-800 px-0.5 rounded'>tenho de</mark> estudar. / Eu <mark class='bg-blue-200 dark:bg-blue-800 px-0.5 rounded'>tenho que</mark> estudar.
'Dever' can also translate to 'must' or 'have to'.
While 'dever' can express a strong obligation, it also carries connotations of moral duty, recommendation, or probability. 'Ter de' is more straightforwardly about a factual necessity or obligation, often due to external circumstances or rules. For instance, 'Você deve estudar' could mean 'You should study' (advice) or 'You must study' (strong obligation), whereas 'Você tem de estudar' almost always means 'You have to study' (a requirement).
Você <mark class='bg-blue-200 dark:bg-blue-800 px-0.5 rounded'>deve</mark> ser pontual. (You should be punctual. / You must be punctual.) vs. Você <mark class='bg-blue-200 dark:bg-blue-800 px-0.5 rounded'>tem de</mark> ser pontual. (You have to be punctual - likely due to a rule.)
Both express necessity.
'Ser preciso' is an impersonal construction meaning 'it is necessary'. It's not tied to a specific subject doing the action. 'Ter de' is personal, indicating that a specific subject has the obligation. For example, 'É preciso estudar' means 'It is necessary to study', while 'Eu tenho de estudar' means 'I have to study'.
<mark class='bg-blue-200 dark:bg-blue-800 px-0.5 rounded'>É preciso</mark> chegar cedo. (It is necessary to arrive early.) vs. Eu <mark class='bg-blue-200 dark:bg-blue-800 px-0.5 rounded'>tenho de</mark> chegar cedo. (I have to arrive early.)
Both imply something needs to be done.
'Necessitar de' means 'to need to' and focuses on the need or requirement for something. 'Ter de' emphasizes the obligation or duty to perform an action. While needing to do something often implies an obligation, 'necessitar de' is about the lack or requirement, while 'ter de' is about the action that must be performed.
Eu <mark class='bg-blue-200 dark:bg-blue-800 px-0.5 rounded'>necessito de</mark> comprar pão. (I need to buy bread - focus on the lack of bread.) vs. Eu <mark class='bg-blue-200 dark:bg-blue-800 px-0.5 rounded'>tenho de</mark> comprar pão. (I have to buy bread - focus on the action required.)
Both convey a sense of obligation.
'Obrigar-se a' means 'to oblige oneself to' or 'to make oneself do something'. It implies a self-imposed obligation or a strong personal commitment. 'Ter de' is more general and can refer to obligations imposed by external factors, rules, or personal circumstances. 'Obrigar-se a' is more about internal resolve.
Ele <mark class='bg-blue-200 dark:bg-blue-800 px-0.5 rounded'>obrigou-se a</mark> aprender português. (He obliged himself to learn Portuguese.) vs. Ele <mark class='bg-blue-200 dark:bg-blue-800 px-0.5 rounded'>tem de</mark> aprender português. (He has to learn Portuguese - perhaps for work.)

'Ter' is an irregular verb. Using the wrong form, like 'Nós tem de estudar', is a common error. Ensure you use the correct conjugation for each subject (eu tenho, tu tens, ele/ela/você tem, nós temos, vós tendes, eles/elas/vocês têm).
-
Using 'ter' alone for obligation
→
Eu tenho de trabalhar.
The verb 'ter' by itself means 'to have' (possession). To express obligation ('to have to'), you must use the construction 'ter de' or 'ter que'. 'Eu tenho trabalhar' is incorrect.
-
Confusing 'ter de' with 'dever'
→
Você tem de pagar a conta. (You have to pay the bill - obligation)
'Dever' can mean 'must' but often implies moral duty or probability ('should'). 'Ter de' is more about a direct necessity or obligation. 'Você deve pagar a conta' could mean 'You should pay the bill' or 'You must pay the bill' (moral/strong recommendation).
-
Using 'ter de' for possibility
→
Eu posso ir agora. (I can go now - possibility/permission)
'Ter de' expresses obligation, not possibility or permission. For those meanings, use 'poder' (can/may). 'Eu tenho de ir agora' means 'I have to go now' (it's an obligation).
Astuces
The Crucial 'de'
Never forget the preposition 'de' after the conjugated verb 'ter'. It's the key element that transforms 'ter' (to have) into the obligation phrase 'ter de' (to have to). Always say 'Eu tenho de ir', not 'Eu tenho ir'.
Unstressed 'de'
In spoken Portuguese, the 'de' in 'ter de' is often unstressed and can sound like 'dji'. Practice saying 'tenho dji ir', 'temos dji fazer' to sound more natural.
Conjugation is Key
'Ter' is an irregular verb. Master its present, past, and future conjugations to use 'ter de' correctly with any subject and in any tense. Practice lists of conjugations regularly.
Context Matters
While 'ter de' is versatile, consider if 'dever' (should/must) or 'ser preciso' (it is necessary) might fit better in certain contexts, especially for moral obligations or impersonal necessities.
Sentence Building
Create your own sentences using 'ter de' based on your daily life. 'Tenho de trabalhar', 'Tenho de estudar', 'Tenho de comprar pão'. This active recall is highly effective for memorization.
Native Speaker Immersion
Listen to Portuguese podcasts, music, or watch movies. Pay attention to how native speakers use 'ter de' in different situations. This will help you grasp the natural flow and common collocations.
'Ter de' vs. 'Ter que'
Understand that 'ter de' and 'ter que' are often interchangeable. While regional preferences exist, using either is usually acceptable. Focus on mastering one first, then explore the other.
Avoid 'Ter' Alone
Never use 'ter' alone to express obligation like 'Eu tenho ir'. This is incorrect. Always include 'de' (or 'que') followed by the infinitive: 'Eu tenho de ir'.
Role-Playing
Imagine scenarios: you're a student, a worker, a parent. What do you 'ter de' do in each role? Role-play these situations to practice the phrase in context.
Regular Revision
Revisit the conjugation of 'ter' and common 'ter de' phrases regularly. Consistent review will help cement this essential vocabulary into your active memory.

Origine du mot
The phrase 'ter de' originates from the Latin verb 'tenēre', meaning 'to hold' or 'to have'. Over time, in Vulgar Latin and its descendants like Portuguese, 'tenēre' evolved to express possession ('ter') and also necessity when combined with other particles or prepositions.
Sens originel : Originally, 'ter' meant possession. The addition of 'de' and an infinitive verb developed to express obligation, moving from a physical holding to a conceptual holding of duty.

Using 'ter de' is generally neutral. However, the context in which it's used can imply pressure or a lack of choice, so be mindful of the tone and situation.
While English has 'have to' and 'must', the Portuguese 'ter de' is a very direct and frequently used equivalent that covers a broad spectrum of obligations, from minor daily tasks to significant life duties.

Questions fréquentes
10 questionsYes, 'ter de' is a verbal locution that must always be followed by a verb in its infinitive form. The preposition 'de' connects the conjugated verb 'ter' to the action that needs to be performed. For example: 'Eu tenho de comer' (I have to eat), where 'comer' is the infinitive.
Absolutely. You conjugate the verb 'ter' according to the desired tense. For example, in the past: 'Eu tive de estudar.' (I had to study.) In the future: 'Nós teremos de esperar.' (We will have to wait.)
In most contexts, they are interchangeable and mean 'to have to'. 'Ter de' can sometimes be perceived as slightly more formal or a stronger obligation, particularly in European Portuguese. 'Ter que' is generally more common in Brazilian Portuguese and can sound more colloquial. Both are widely understood.
To make a sentence negative, you place the word 'não' before the conjugated verb 'ter'. For example: 'Eu não tenho de ir.' (I don't have to go.)
It's used for strong obligations and necessities. This can range from strict rules ('You have to wear a seatbelt') to personal needs ('I have to buy groceries') or commitments ('We have to finish this project'). The context clarifies the type of obligation.
Yes, it can. The reflexive pronoun usually comes before the infinitive verb. For example: 'Nós temos de nos preocupar.' (We have to worry.)
Forgetting the 'de' is a common mistake and makes the sentence grammatically incorrect. For instance, 'Eu tenho comer' is wrong; it must be 'Eu tenho de comer'. The 'de' is essential for the phrase to function as an expression of obligation.
It's very close. 'Ter de' is the most common equivalent for 'to have to'. While English 'must' can express strong obligation, 'ter de' covers a wider range of necessities and obligations, from simple tasks to more serious duties. 'Dever' is often closer to 'must' when expressing moral obligation or strong recommendation.
You can form questions by inverting the subject and verb or by using question words. For example: 'Tens de ir?' (Do you have to go?) or 'O que temos de fazer?' (What do we have to do?).
'Ter de' is appropriate for expressing necessity or obligation. If you want to express possibility, permission, or ability, you would use verbs like 'poder' (can/may) or 'conseguir' (to manage to). For advice or recommendations, 'dever' is often more suitable.
