Health, Needs, and Obligations · Speak and Write Portuguese: Foundations of Practical Communication

Chapter Overview

This chapter closes Unit III by giving you the language to describe how you feel, say what you need, and talk about obligations. You will build on the request and help vocabulary from Capítulo 13 (Você pode me ajudar?, poder, saber, conseguir) and add the pattern estar com for physical states and symptoms, the verb precisar for needs, ter que and dever for obligation and advice, and reflexive se as a recognition item in common formulas like sentir-se. Together these systems let you describe basic symptoms, express what you need, and talk about what you or someone else must or should do.

Chapter Objectives

By the end of this chapter, you will be able to:

  1. Describe basic physical states and symptoms using estar com.
  2. Express needs using precisar de and precisar + infinitive.
  3. Express obligation using ter que + infinitive.
  4. Give advice or express a softer obligation using dever + infinitive.
  5. Recognize reflexive se in the formula sentir-se without producing the full reflexive system.
  6. Combine these systems into a short spoken and written exchange about health and needs.

Communication Scenario

You are not feeling well, or a friend is not feeling well. You describe the symptoms, say what you need, and talk about what you have to do or should do about it — for example, resting, calling a doctor, or missing a class or a shift at work.

  1. This chapter activates estar com, precisar, ter que, and dever for the first time, and introduces reflexive se only as a recognition item.
  2. Full reflexive verb conjugation remains outside this chapter's scope; here, sentir-se and similar forms are learned only as fixed formulas.
  3. You may invent your own symptom or situation if you prefer not to describe a real one.

Core Vocabulary

The following vocabulary supports describing basic symptoms, needs, and obligations at a beginner level.

Grammar and Sentence Patterns

Describing symptoms: Estou com dor de cabeça

Use estar com plus a noun to describe a temporary physical state or symptom. This recycles estar from earlier chapters in a new formulaic pattern.

Building Block
estar (conjugated) + com + noun
The noun does not take an article in this fixed pattern.
Estou com dor de cabeça.
I have a headache. (Literally: I am with headache.)
  • Meu amigo está com febre. My friend has a fever.
  • Nós estamos com fome e com sede. We are hungry and thirsty. (recycled from earlier vocabulary)

Estar com is a fixed formula for temporary physical and emotional states. Do not confuse it with ter alone, which you already use for possession and age.

Expressing needs: Precisar de and precisar + infinitive

Precisar changes its pattern depending on whether it is followed by a noun or a verb.

  • Eu preciso de um médico. I need a doctor. precisar de + noun
  • Eu preciso descansar hoje. I need to rest today. precisar + infinitive, no preposition

Use precisar de before a noun and precisar alone before an infinitive. Do not insert de before a verb.

Ter que and dever

Both ter que and dever express obligation, but they differ in strength.

  • Eu tenho que ir ao médico amanhã. I have to go to the doctor tomorrow. ter que — strong, often necessary obligation
  • Você deve descansar mais. You should rest more. dever — advice or softer obligation

Do not treat ter que and dever as interchangeable. Ter que presents an action as necessary or required; dever presents an action as advisable or recommended.

Language Focus — Recognizing reflexive se

Some Portuguese verbs use a reflexive pronoun to show that the action affects the subject. You will see this in the fixed expressions sentir-se bem and sentir-se mal ("to feel well," "to feel bad"). In this chapter, treat these as whole formulas to recognize and understand, not as a system to build new sentences with. Eu não estou me sentindo bem. ("I'm not feeling well.") The full reflexive system develops later in the series.

Model Dialogue

Context: Two coworkers talking before a shift, neutral informal register.
Marina Oi, Rafael. Tudo bem? Você está bem? Hi, Rafael. How's it going? Are you okay?
Rafael Não muito. Estou com dor de cabeça e com um pouco de febre. Not really. I have a headache and a bit of a fever.
Marina Nossa. Você precisa descansar. Você já tomou algum remédio? Wow. You need to rest. Have you taken any medicine?
Rafael Ainda não. Acho que eu tenho que ir à farmácia depois do trabalho. Not yet. I think I have to go to the pharmacy after work.
Marina Você não deveria trabalhar hoje. Você deve ligar para o médico e faltar ao trabalho, se precisar. You shouldn't work today. You should call the doctor and miss work, if you need to.
Rafael Talvez você tenha razão. Eu não estou me sentindo bem mesmo. Maybe you're right. I really am not feeling well.
Marina Vai para casa. Eu posso te ajudar aqui hoje. Go home. I can help out here today.

Note estou com dor de cabeça, você precisa descansar, eu tenho que ir, você deve ligar, and eu não estou me sentindo bem together in this exchange — each pattern doing a distinct communicative job.

Guided Practice

  1. Reread the model dialogue and underline every use of estar com, precisar, ter que, and dever.
  2. Choose precisar de or precisar: Eu ______ um médico. / Ela ______ descansar. / Nós ______ de água.
  3. Choose ter que or dever: Amanhã eu ______ ir ao trabalho, mesmo doente. (obligatory) / Você ______ tomar mais água. (advice)
  4. Write one sentence describing a symptom, using estar com + a body-related noun.

Listening Task

If no audio recording is available, ask a partner, instructor, or text-to-speech tool to read the script below aloud, or read it aloud to yourself slowly.

Listening script
Oi, mãe. Eu não estou me sentindo bem. Estou com dor de garganta e um pouco de tosse. — Você está com febre? — Acho que não, mas estou muito cansado. — Você precisa descansar hoje. Você deve tomar bastante água e talvez um chá quente. — Eu tenho que ir à aula às dez, mas acho que vou faltar. — Isso mesmo. Você não deve sair de casa assim. Se a garganta não melhorar amanhã, você tem que ir ao médico.
Hi, Mom. I'm not feeling well. I have a sore throat and a bit of a cough. — Do you have a fever? — I don't think so, but I'm very tired. — You need to rest today. You should drink plenty of water and maybe a hot tea. — I have class at ten, but I think I'm going to miss it. — That's right. You shouldn't leave the house like this. If your throat doesn't get better tomorrow, you have to go to the doctor.
  1. What symptoms does the speaker describe?
  2. What does the mother recommend?
  3. What will happen if the throat doesn't improve by tomorrow?

Speaking Task

Prática controlada — Controlled practice: three sentences

Say each sentence aloud: Estou com ______. (a symptom); Eu preciso ______. (something you need to do); Eu tenho que ______ / Eu devo ______. (an obligation or a piece of advice)

Tarefa comunicativa — Communicative task: describe and advise

With a partner, take turns describing a symptom using estar com, then give advice or state an obligation using precisar, ter que, or dever.

Prática individual — Solo alternative

Record yourself describing a time you did not feel well, what you needed, and what you had to do or should have done, using at least three of the four patterns from this chapter.

Reading Task

Uma mensagem para o professor

Bom dia, professor. Desculpe incomodar. Eu não estou me sentindo bem hoje. Estou com dor de barriga e um pouco de febre. Eu preciso descansar em casa e acho que tenho que faltar à aula. Eu devo ir ao médico se a febre não melhorar. Eu preciso do material da aula de hoje, se possível. Muito obrigado pela compreensão.

Notice estou com dor de barriga, eu preciso descansar, tenho que faltar, and devo ir ao médico in this message, all recycled naturally into a single written request.

Tarefa de leitura — Reading task:

  1. What symptoms does the student describe?
  2. What does the student say they have to do?
  3. What does the student ask the teacher for?

Writing Task

Complete the following linked writing tasks in order to build a short message about not feeling well.

Tarefa 1 — Symptom: Write one sentence describing a symptom using estar com.

Tarefa 2 — Need: Write one sentence using precisar de or precisar + infinitive.

Fill in the blank
Oi! Eu não estou me sentindo bem. Estou com ______. Eu preciso ______. Eu acho que tenho que ______. Eu devo ______, se não melhorar. Obrigado pela compreensão!
Hi! I'm not feeling well. I have ______. I need ______. I think I have to ______. I should ______, if it doesn't get better. Thanks for understanding!

Tarefa 3 — Obligation and advice: Write one sentence with ter que and one sentence with dever, keeping their meanings distinct.

Tarefa 4 — Full message: Combine Tarefas 1–3 into one short message of five to six sentences explaining that you are not feeling well, following the model of the Reading Task passage.

  1. Draft each section separately. Write the symptom, the need, and the obligation/advice sentences one at a time before combining them.
  2. Combine the sections into one message. Add a greeting at the start, recycled from Capítulo 1.
  3. Check precisar de vs. precisar. Confirm you used de before a noun and no preposition before a verb.
  4. Check ter que vs. dever. Confirm the verb matches strong obligation or softer advice.
  5. Check diacritics. Confirm that forms such as é, não, and médico keep their correct spelling.

Lista de revisão — Editing checklist:

  • The message includes a greeting, a described symptom, a need, and an obligation or advice sentence.
  • estar com is used correctly with a body-related or symptom noun.
  • precisar de and precisar + infinitive are used correctly.
  • ter que and dever are used for their distinct functions.
  • All diacritics are preserved.

Culture and Communication

Culture in Context — Talking about health

In many Brazilian workplaces and schools, it is common and expected to notify a supervisor or teacher directly when illness prevents attendance, often with a brief message like the one in this chapter's Reading Task. Home remedies such as chás (teas) are frequently mentioned alongside formal medical advice, without one replacing the other.

Regional Variation — Pharmacy access

In Brazil, pharmacies (farmácias) commonly offer informal guidance for minor symptoms and sell many over-the-counter medications without a prescription, a pattern that differs from some other Lusophone countries and from parts of Europe and North America. This is general cultural information, not medical guidance, and specific practices vary by country, region, and pharmacy.

Common Mistakes to Avoid

Common Mistake — Confusing ter que and dever

Error: Saying Você deve ir ao médico agora mesmo, é urgente! when the situation actually requires strong necessity rather than a recommendation.

Correction: Use ter que for strong or necessary obligation: Você tem que ir ao médico agora mesmo. Reserve dever for advice or softer recommendations: Você deve descansar mais esta semana.

Common Mistake — Adding de before an infinitive with precisar

Error: Writing Eu preciso de descansar instead of the correct pattern.

Correction: Use de only before a noun: Eu preciso de um remédio. Before an infinitive, drop de: Eu preciso descansar.

Common Mistake — Overusing reflexive se

Error: Trying to attach se freely to other verbs, as if the full reflexive system were already active.

Correction: At this stage, recognize se only in the fixed formula sentir-se bem/mal. Broader reflexive verb production develops in later volumes.

Chapter Summary

O que você praticou — What you practiced
