Expressing Obligation: How to Use 'Ter Que'
Grammar Rule in 30 Seconds
Use 'ter que' + infinitive to express a personal obligation or necessity in Portuguese.
- Conjugate 'ter' to match the subject: 'Eu tenho que estudar'.
- Always follow with the preposition 'que' and an infinitive verb.
- In negative sentences, 'não ter que' often implies a lack of obligation.
Overview
To express obligation or necessity in Portuguese, you primarily use the construction ter que + infinitive. This structure is fundamental for A2 learners, serving as the direct equivalent of "to have to" or "must" in English. It conveys a strong sense of duty, requirement, or external compulsion.
Mastering ter que is crucial for navigating everyday communication in Portuguese, as it is one of the most frequently used grammatical patterns.
For instance, if you need to state that you are required to work, you would say Eu tenho que trabalhar. This phrasing indicates a non-negotiable commitment. Similarly, if there's a deadline, you might hear Você tem que entregar o relatório até amanhã, emphasizing the imperative nature of the task.
The ubiquity of ter que across all registers of Portuguese—from formal announcements to casual text messages—underscores its importance in achieving functional fluency.
How This Grammar Works
ter que + infinitive functions as a periphrastic verb, where ter (to have) acts as an auxiliary verb, and que serves as an invariable connective particle linking ter to the main action verb in its infinitive form. The linguistic principle behind this is a common evolution in Romance languages, where verbs of possession (ter) or existence (ser/estar) combine with a conjunction to express modality—specifically, obligation. Ter loses its literal meaning of possession in this context and instead conveys a sense of obligation or necessity.Eu tenho um carro (I have a car) uses ter to express possession. However, in Eu tenho que comprar um carro (I have to buy a car), ter combines with que and the infinitive comprar to signify an obligation. The main verb (comprar) remains unconjugated, carrying the core meaning of the action.ter que is overwhelmingly common, particularly in Brazilian Portuguese, you may also encounter ter de + infinitive. In Portugal, ter de is historically considered more grammatically precise and is often taught in educational settings. However, in contemporary spoken European Portuguese, ter que is also widely used and accepted, especially in informal contexts.ter de) or informal (with ter que) register. For A2 learners primarily focused on Brazilian Portuguese, ter que is the standard and most practical option.Word Order Rules
ter que is consistent and straightforward. Adhering to this structure ensures clarity and grammatical correctness.ter + que + Infinitive Verb- The subject determines the conjugation of
ter. queremains constant, never changing form.- The second verb always stays in its infinitive (
-ar,-er,-ir) form, regardless of the subject or tense ofter.
Nós temos que estudar para o exame.(We have to study for the exam.)Ela tem que sair cedo hoje.(She has to leave early today.)
não directly before the conjugated form of ter. No other words should come between não and ter.Não + Conjugated ter + que + Infinitive VerbEu não tenho que ir ao banco agora.(I don't have to go to the bank now.)Eles não têm que trabalhar no fim de semana.(They don't have to work on the weekend.)
ter or follow the infinitive. Crucially, nothing should ever separate ter, que, and the infinitive verb. These three elements form a fixed unit.Sempre temos que verificar os dados.(We always have to check the data.)Temos que verificar os dados sempre.(We have to check the data always.)
- 1Attached to the infinitive (most common in Brazil): The pronoun is placed after the infinitive verb, connected with a hyphen.
Eu tenho que me arrumar rapidamente.(I have to get myself ready quickly.)Você tem que lavá-lo amanhã.(You have to wash it tomorrow.)
- 1Before the conjugated
ter(also correct, less common in informal Brazilian Portuguese): The pronoun precedes the conjugatedter.
Eu me tenho que arrumar rapidamente.Você o tem que lavar amanhã.
ter que, the word order typically remains the same as an affirmative statement. The interrogative nature is conveyed primarily through intonation in spoken Portuguese, or with a question mark in written form. Subject-verb inversion, while possible, is less common than in English.Você tem que trabalhar hoje?(Do you have to work today?)Eles têm que viajar amanhã?(Do they have to travel tomorrow?)
Formation Pattern
ter que is a systematic process. You will follow a consistent sequence: identify the subject, conjugate ter accordingly, insert que, and then add the main action in its infinitive form. The primary challenge for learners is mastering the conjugations of ter in different tenses, as ter is an irregular verb.
Eu, Você, Ele/Ela, Nós, Vocês/Eles/Elas).
ter: Match ter to your chosen subject and the desired tense. For A2, focus on the present tense (Presente do Indicativo), simple past (Pretérito Perfeito Simples), and the periphrastic future (Futuro Próximo).
que: This connective particle is always present and invariant.
-ar, -er, or -ir).

When To Use It
ter que is employed to convey various forms of obligation, necessity, or duty. Its usage is pervasive across different contexts due to its direct and forceful implication.Ter que indicates that an action is mandatory, often due to rules, laws, schedules, external circumstances, or instructions from another person. The obligation is typically perceived as originating from outside the speaker.Eu tenho que entregar meu passaporte na embaixada.(I have to submit my passport at the embassy – external requirement).Você tem que acordar cedo para pegar o voo.(You have to wake up early to catch the flight – dictated by circumstance).
ter que can also express a strong internal conviction or a perceived personal necessity, especially when the speaker feels compelled to perform an action.Eu tenho que falar com ele sobre o projeto.(I have to talk to him about the project – strong personal feeling of necessity).Nós temos que ser mais cuidadosos.(We have to be more careful – a strong conviction or advisement).
ir + ter que), it can suggest an unavoidable event or consequence.Se chover, nós vamos ter que cancelar o piquenique.(If it rains, we will have to cancel the picnic – an unavoidable consequence).Para resolver isso, você vai ter que ligar para o suporte.(To solve this, you will have to call support – an inevitable next step).
se):ter que can be used with the impersonal pronoun se to express a general obligation.Tem-se que respeitar as regras de trânsito.(One has to respect traffic rules – a general obligation).- (Note: This is less common and more formal than using a specific subject like
As pessoas têm que…)
ter que communicates a strong, often non-negotiable requirement.Common Mistakes
ter que. Recognizing and understanding these common errors is key to developing accurate Portuguese.que:Eu tenho trabalhar. This is incorrect. Without que, ter retains its meaning of possession, making the sentence nonsensical in the context of obligation.- Incorrect:
*Eu tenho trabalhar.(Incorrectly means "I have to work" in a possessive sense, which is not possible.) - Correct:
Eu tenho que trabalhar.(I have to work.) - Why it's wrong: The
queis the essential grammatical link that transformsterfrom a verb of possession into an auxiliary verb of obligation.
ter should be conjugated to agree with the subject and tense. The second verb, which describes the main action, must always remain in its infinitive form.- Incorrect:
*Ela tem que estuda.(Attempting to conjugateestudarasestuda) - Correct:
Ela tem que estudar.(She has to study.) - Why it's wrong: Periphrastic constructions rely on the auxiliary verb (
ter) to carry tense and subject agreement, while the main verb (estudar) provides the lexical meaning without inflection.
ter and que:ter que + infinitive is syntactically fixed. Inserting adverbs or other words between ter and que is ungrammatical.- Incorrect:
*Eu tenho sempre que comer salada.(Incorrect word order for the adverbsempre) - Correct:
Eu sempre tenho que comer salada.OREu tenho que comer salada sempre.(I always have to eat salad.) - Why it's wrong:
ter queacts as a cohesive verbal unit, and breaking it disrupts the intended meaning and flow.
não in Negation:não must directly precede the conjugated form of ter.- Incorrect:
*Eu tenho não que ir. - Correct:
Eu não tenho que ir.(I don't have to go.) - Why it's wrong: In Portuguese, the negating particle
nãogenerally comes before the main or auxiliary verb it modifies.
dever (should):ter que implies a stronger, often external, and less negotiable requirement, whereas dever suggests a milder, more internal or advisable obligation.- Context for
dever:Eu devo comer salada.(I should eat salad – it's good for me, a recommendation.) - Context for
ter que:Eu tenho que comer salada.(I have to eat salad – doctor's orders, a strict requirement.) - Why it's wrong to confuse them: Using
ter quewheredeveris appropriate can make your statement sound overly forceful or demanding, altering the nuance of your message.
