解説 cadeira in your Level:

At the A1 level, 'cadeira' is simply one of the first household objects you learn. You should be able to identify it in a room, ask for one if you need to sit down, and describe its color or location using basic prepositions. For example: 'A cadeira é branca' (The chair is white) or 'A cadeira está na cozinha' (The chair is in the kitchen). The focus is purely on the physical object and basic grammar like gender (feminine) and number (plural: cadeiras). You might also learn 'cadeira de rodas' (wheelchair) as part of basic vocabulary for public spaces. The goal is to survive a basic conversation where seating is involved, such as at a friend's house or a small cafe.

At the A2 level, you begin to use 'cadeira' in more varied contexts and with more complex sentence structures. You will learn to use it with verbs of movement and position, such as 'puxar uma cadeira' (to pull up a chair) or 'trocar as cadeiras' (to swap the chairs). You also start to encounter common types of chairs, like 'cadeira de escritório' (office chair) or 'cadeira de praia' (beach chair). At this stage, you should be comfortable using possessives ('minha cadeira') and demonstratives ('aquela cadeira'). You might also be introduced to the idea that 'cadeira' can mean a university subject, particularly if you are studying European Portuguese, though the focus remains largely on the furniture.

By B1, you are expected to understand the metaphorical and idiomatic uses of 'cadeira'. You will recognize terms like 'cadeira cativa' (a reserved seat or a regular spot) and understand the plural 'cadeiras' when used informally in Brazil to mean hips. Your vocabulary expands to include more specific seating like 'poltrona' (armchair) or 'banqueta' (stool), and you can explain the differences between them. In an academic setting, you can discuss your university schedule using 'cadeiras' (in Portugal) or 'matérias' (in Brazil) fluently, using past and future tenses to describe the courses you have taken or will take. You can also describe the materials and comfort levels of different chairs in detail.

You are aware of the regional differences between Portugal and Brazil regarding academic terminology and anatomical slang. You can participate in a debate about ergonomics in the workplace, using 'cadeira de escritório' as a focal point. Your understanding of the word is now integrated into a broader cultural context, recognizing how the 'cadeira' serves as a symbol of authority, comfort, or academic progress depending on the situation. You use the word accurately in complex grammatical constructions, including passive voice and subjunctive moods.

cadeira 30秒で

Cadeira is the Portuguese word for chair, a feminine noun used daily in all Lusophone countries for furniture.
In Portugal, it is the standard term for a university course or subject, replacing 'matéria' or 'disciplina'.
In Brazil, 'as cadeiras' (plural) is a common informal way to refer to the hips, especially regarding movement.
The word can also represent a position of power or a reserved seat in a formal organization or stadium.

The Portuguese word cadeira is a fundamental noun that every learner must master early in their journey. At its most basic level, it refers to a chair—a piece of furniture designed for one person to sit on, typically having a back and four legs. However, the depth of this word in Lusophone cultures extends far beyond the dining room or the classroom. In European Portuguese, especially, cadeira is the standard term for a university subject or course. When a student in Lisbon says they have a difficult cadeira of mathematics, they aren't talking about the furniture they sit on, but rather the academic module they are enrolled in. This usage stems from the Latin 'cathedra', which represented the seat of a professor or a person of authority. Therefore, the 'chair' represents the position or the authority of the knowledge being taught.

Physical Object: A piece of furniture with a backrest and seat. Example: 'A cadeira da cozinha é de madeira' (The kitchen chair is made of wood).
Academic Subject: A specific unit of study in higher education. Example: 'Fui aprovado na cadeira de História' (I passed the History course).
Anatomy (Informal): In Brazil, 'as cadeiras' refers to the hips. Example: 'Ela sabe mexer as cadeiras' (She knows how to move her hips).

Por favor, puxe uma cadeira e junte-se a nós para o jantar.

In everyday life, you will encounter various types of cadeiras. There is the cadeira de rodas (wheelchair), essential for accessibility, and the cadeira de balanço (rocking chair), often associated with comfort and the elderly. In professional environments, the cadeira de escritório (office chair) is a staple. The word is also used metaphorically to describe a position of power. To 'occupy a chair' in an academy of letters or a political body signifies holding a permanent and prestigious seat. This versatility makes cadeira a rich word that bridges the gap between domestic simplicity and professional or academic achievement. Whether you are sitting down to rest, studying for a final exam, or dancing at a carnival, the word cadeira finds its way into the conversation. It is a feminine noun, so it always takes feminine articles and adjectives, such as a cadeira, esta cadeira, or uma cadeira confortável. Understanding these nuances allows a learner to move from basic identification to nuanced communication in both Portugal and Brazil.

Using cadeira correctly involves understanding its grammatical gender and how it interacts with verbs. As a feminine noun, it requires the article a (the) or uma (a/an). When you want to describe the chair, the adjectives must also be feminine. For example, 'a cadeira é nova' (the chair is new) or 'as cadeiras são pesadas' (the chairs are heavy). Verbs commonly associated with this noun include sentar-se (to sit down), puxar (to pull), and quebrar (to break).

Sitting Down: Eu vou me sentar naquela cadeira azul que está no canto da sala.
Ownership/Placement: Esta cadeira pertence ao meu avô; ela é uma antiguidade muito valiosa.

A criança não para quieta na cadeira durante a aula.

When referring to the academic context, the verb fazer (to do/take) is frequently used. 'Estou a fazer a cadeira de macroeconomia' (I am taking the macroeconomics course). In Brazil, when referring to hips, you might hear the verb rebolar (to sway/wiggle). 'Ela rebolou as cadeiras ao som do samba' (She swayed her hips to the sound of samba). This distinction is vital for learners to avoid confusion between furniture and body parts. In a restaurant, you might ask the waiter, 'Pode trazer mais uma cadeira?' (Can you bring one more chair?), which is a very common and practical use of the word. Another interesting usage is the term cadeira cativa, which refers to a reserved seat, often in a stadium or theater, but is also used metaphorically for someone who is always present in a specific place or situation. For example, 'Ele tem cadeira cativa neste bar' means he is a regular customer who is always there. This idiomatic use shows how the physical object becomes a symbol of belonging and status. When constructing sentences, remember that 'cadeira' can be part of compound nouns like cadeira de braços (armchair) or cadeira de praia (beach chair). These compounds follow the pattern [Noun] + de + [Purpose/Description], which is a very productive pattern in Portuguese grammar.

The word cadeira is ubiquitous. You will hear it in the most mundane domestic situations and the most formal academic or political environments. In a typical Portuguese home, the sala de jantar (dining room) is the primary location for cadeiras. Parents might tell their children, 'Senta direito na cadeira!' (Sit properly in the chair!) during dinner. In a school setting, teachers ask students to keep their cadeiras in line. At the beach, especially in Brazil, the cadeira de praia is an essential item, and you will hear vendors renting them out: 'Aluguel de cadeiras e guarda-sóis!' (Chairs and umbrellas for rent!).

O palestrante pediu que todos tomassem seus lugares nas cadeiras da primeira fila.

In the context of health and accessibility, cadeira de rodas is a term heard in hospitals, airports, and public transport. Understanding this term is crucial for providing or receiving assistance. In the academic world of Portugal, the start of a semester is filled with talk about cadeiras. Students discuss which cadeiras are the hardest or which ones they have already completed (concluído). 'Quantas cadeiras tens este semestre?' (How many courses do you have this semester?) is a standard question among university peers. In Brazil, during Carnival or at a dance club, you might hear the word used anatomically. Lyrics in popular music often mention 'mexer as cadeiras' (moving the hips), celebrating the rhythm and dance culture of the country. Even in politics, the 'disputa por uma cadeira no Senado' (the race for a seat in the Senate) is a common headline during election cycles. This broad range of environments—from the sandy beaches of Rio to the ancient halls of the University of Coimbra—demonstrates that cadeira is a high-frequency word that adapts to its surroundings. It is not just a piece of wood or plastic; it is a seat of learning, a tool for mobility, a rhythm of the body, and a position of social standing. Listening for the context—whether there are books, music, or sand around—will help you immediately identify which 'cadeira' is being discussed.

One of the most frequent mistakes for English speakers learning Portuguese is the confusion between cadeira and other types of seating. While English uses 'chair' for almost anything with a back, Portuguese is more specific. A banco is a stool or a bench (usually without a backrest), and a poltrona is a large, comfortable armchair, often found in a living room for watching TV. Calling a plush armchair a 'cadeira' might sound slightly odd to a native speaker, though it is technically correct in a broad sense. Another mistake involves the plural usage in Brazil. If you say 'minha cadeira dói' (my chair hurts), people will look at you strangely; you must say 'minhas cadeiras doem' (my hips hurt) if you are referring to your body, although 'quadril' is the more formal anatomical term.

Cadeira vs. Banco: A 'cadeira' has a backrest; a 'banco' (stool) usually does not. Use 'banco' for a park bench or a bar stool.
Cadeira vs. Poltrona: A 'poltrona' is upholstered and much more comfortable than a standard 'cadeira'.

Não confunda a cadeira de jantar com o banco do jardim.

Grammatically, learners often forget that cadeira is feminine. Saying 'o cadeira' is a common error for beginners. Remember: a cadeira, esta cadeira, minha cadeira. Another subtle mistake occurs in the academic context. In Brazil, if you ask a student 'Qual cadeira você está fazendo?', they will understand you, but it sounds very formal or old-fashioned; they would typically say 'Qual matéria você está fazendo?'. Conversely, in Portugal, using 'matéria' to mean a university course might be misunderstood as the 'content' or 'subject matter' of a specific lesson, rather than the course itself. Finally, be careful with the phrase 'cadeira elétrica'. While it obviously means electric chair, using it metaphorically in Portuguese isn't as common as in English unless you are specifically talking about capital punishment or a very high-pressure situation in a very specific slang context. Stick to the literal meanings until you are very comfortable with the language's nuances.

To enrich your Portuguese vocabulary, it is helpful to know words related to cadeira. While 'cadeira' is the general term, several alternatives provide more specificity depending on the design and function of the seat. For example, assento is a more formal and general term meaning 'seat'. You see this in airplanes ('aperte o cinto no seu assento') or theaters. If you are looking for something more comfortable, poltrona is the word for armchair. For a seat without a back, like at a bar or in a park, use banco.

Assento: A general term for any place to sit. Used in official contexts, like 'assento parlamentar' (parliamentary seat).
Sofá: A couch or sofa, designed for multiple people. Much larger than a 'cadeira'.
Banqueta: A high stool, typically used at a kitchen counter or a bar.

Em vez de uma cadeira comum, ele prefere sentar-se em um banco alto.

In academic contexts, synonyms for 'cadeira' (as a subject) include disciplina and matéria. 'Disciplina' is the most formal and official term used in university transcripts. 'Matéria' is the most common informal term in Brazil for any subject from primary school to college. In the anatomical sense, quadril is the proper medical and formal word for 'hip', while ancas is another term often used for the hips of animals or in a slightly more coarse way for humans in some regions. Knowing these synonyms allows you to adjust your register. You might use 'cadeira' at home, 'assento' when booking a flight, 'disciplina' when talking to a professor, and 'quadril' when talking to a doctor. This linguistic flexibility is a hallmark of an advanced learner. Additionally, consider the word trono (throne), which is essentially a 'cadeira' for a king or queen. While you won't use it often, it highlights the 'status' aspect that the word 'cadeira' can sometimes carry.
