解説 sistema in your Level:

At the A1 level, the word sistema is introduced primarily as a cognate to the English 'system'. Students learn that it is a masculine noun despite the '-a' ending. The focus is on very concrete examples that are easy to visualize. Common phrases include 'sistema solar' (solar system) and 'sistema de som' (sound system). A1 learners should practice saying 'o sistema' and 'um sistema' to build the correct habit from the start. They might use it in simple sentences like 'O sistema é novo' (The system is new). The goal is to recognize the word in text and understand its basic meaning in everyday technology and nature.

At the A2 level, learners expand their use of sistema to include public services and basic biology. They start to use terms like 'sistema de transporte' (transport system) and 'sistema de saúde' (health system). This is also where the importance of adjective agreement is emphasized—learning to say 'sistema público' or 'sistema complexo'. A2 students should be able to describe a problem with a system, such as 'O sistema não funciona' (The system doesn't work). They also begin to see the word in compound forms and understand how it functions in slightly more abstract contexts, like a 'sistema de segurança' at home or work.

At the B1 level, sistema moves into the realm of social and political structures. Students discuss the 'sistema político', 'sistema econômico', and 'sistema educacional'. They are expected to use the word in more complex sentences involving prepositions and contractions, such as 'Eu não concordo com o sistema atual' (I don't agree with the current system). B1 learners also encounter the word in professional contexts, like 'sistema de gestão' (management system). They start to understand the nuance between 'sistema' and 'método' and can choose the appropriate word based on whether they are talking about a broad structure or a specific technique.

At the B2 level, learners use sistema to discuss abstract concepts and complex interactions. They might talk about a 'sistema de crenças' (belief system) or the 'sistema jurídico' (legal system). At this stage, students should be comfortable using the word in debates and essays, analyzing how different systems interact. They understand idiomatic uses and can follow technical explanations in their field of interest, whether it's 'sistema de arquivos' in IT or 'sistema endócrino' in medicine. Their pronunciation should be natural, following regional variations, and they should never make gender mistakes with the word.

At the C1 level, sistema is used with high precision in academic and professional discourse. Learners can discuss 'teoria dos sistemas' (systems theory) or the 'sistema de pesos e contrapesos' (system of checks and balances) in a political context. They recognize the word's role in formal writing and can use it to synthesize complex ideas. C1 learners are also aware of the historical and etymological roots of the word and how it has shaped various scientific disciplines. They can use the word metaphorically and understand subtle connotations in literature and high-level journalism, such as when 'o sistema' is used to critique societal norms.

At the C2 level, mastery of sistema is absolute. The speaker uses it with the same flexibility as a native, employing it in philosophical discussions, highly technical scientific papers, or creative writing. They can navigate the most complex bureaucratic 'sistemas' in Lusophone countries without confusion. They understand the word's evolution and its relationship with other Greek-derived terms. A C2 learner can play with the word's meaning in wordplay or rhetoric and can explain its nuances to others. The word is no longer a 'vocabulary item' but a versatile tool for expressing intricate thoughts about the structure of reality and society.

sistema 30秒で

Sistema is a masculine noun meaning 'system'.
It is a Greek-derived word ending in '-ma', which is why it is masculine.
It is used in technology, biology, politics, and everyday life.
Common phrases include 'sistema solar' and 'sistema operacional'.

The Portuguese word sistema is a masculine noun that translates directly to the English word 'system'. Despite ending in the letter 'a', which usually indicates a feminine noun in Portuguese, sistema is one of the many Greek-derived words ending in '-ma' that are masculine, such as 'problema', 'tema', and 'poema'. Understanding this grammatical quirk is essential for beginners. In its most basic sense, a sistema refers to a set of connected things or parts forming a complex whole, or a set of principles or procedures according to which something is done.

Biological Context: In medicine and biology, it describes the functional units of the body. For example, the 'sistema nervoso' (nervous system) or 'sistema imunológico' (immune system). Doctors use this term to explain how different organs interact to maintain health.

O sistema digestivo humano é muito complexo e eficiente.

Technological Context: In the world of computing, it refers to software frameworks. A 'sistema operacional' (operating system) like Windows or macOS is the core software that manages hardware. It is also used for 'sistema de segurança' (security system) or 'sistema de som' (sound system).

Preciso atualizar o sistema do meu computador hoje.

Societal Context: It is frequently used to describe political, economic, or social structures. Phrases like 'sistema educacional' (educational system) or 'sistema político' (political system) are common in news and academic discussions. It can also be used abstractly to refer to 'the establishment' or the way things are organized in society.

Muitas pessoas protestam contra o sistema econômico atual.

O sistema solar possui oito planetas principais.

O engenheiro desenhou um novo sistema de irrigação.

Beyond these, 'sistema' appears in 'sistema de arquivos' (file system), 'sistema métrico' (metric system), and 'sistema de numeração' (numbering system). Its versatility makes it one of the most useful nouns to master early in your Portuguese learning journey. Whether you are talking about the universe, your body, your phone, or your country, this word will likely be part of the conversation.

Using sistema correctly involves paying close attention to adjective agreement and prepositional contractions. Since it is a masculine noun, all accompanying adjectives must also be in the masculine form. For example, you would say 'sistema antigo' (old system) rather than 'sistema antiga'. This is a point of confusion because the 'a' at the end of 'sistema' often tricks the brain into thinking it is feminine.

Adjective Agreement: When describing a system, ensure the adjective matches the masculine gender. Common pairings include 'sistema complexo' (complex system), 'sistema eficaz' (effective system), and 'sistema público' (public system). Even if the adjective ends in 'a' for other words, it must be masculine here.

Eles implementaram um sistema inovador na fábrica.

Prepositional Contractions: Because 'sistema' is masculine, prepositions like 'de', 'em', and 'a' contract with the masculine article 'o'. You will see 'do sistema' (of the system), 'no sistema' (in the system), and 'ao sistema' (to the system). For instance, 'Houve uma falha no sistema' (There was a failure in the system).

A manutenção do sistema é feita mensalmente.

Verbal Collocations: Common verbs used with 'sistema' include 'criar' (to create), 'desenvolver' (to develop), 'instalar' (to install), 'analisar' (to analyze), and 'mudar' (to change). When a system stops working, we say 'o sistema caiu' (the system went down/crashed).

O técnico vai instalar o novo sistema de rede amanhã.

Infelizmente, o sistema bancário está fora do ar.

Nós precisamos entender como esse sistema funciona.

In professional environments, you will often hear 'sistema de gestão' (management system) or 'sistema de qualidade' (quality system). In these cases, the word acts as the anchor for the entire organizational structure being discussed. Mastering the use of 'sistema' in sentences allows you to discuss technical, scientific, and social topics with precision.

The word sistema is ubiquitous in daily life across the Lusophone world. From the moment you wake up and check your phone's 'sistema operacional' to when you pay for coffee using a 'sistema de pagamento', you are interacting with systems.

In the News: News anchors frequently discuss the 'sistema de saúde' (health system), especially during public health crises. You will also hear about the 'sistema prisional' (prison system) or 'sistema judiciário' (judicial system) during reports on law and order. Political analysts often debate the 'sistema eleitoral' (electoral system) during election cycles.

O governo anunciou investimentos no sistema de transporte público.

In the Workplace: In an office setting, 'o sistema' is often the culprit for delays. If a colleague says 'O sistema está lento hoje' (The system is slow today), they are likely referring to the company's internal software or the internet connection. IT departments are constantly 'atualizando o sistema' (updating the system) or 'reiniciando o sistema' (restarting the system).

Não consigo acessar os arquivos porque o sistema caiu.

In Education: Students learn about the 'sistema solar' (solar system) in science class and the 'sistema feudal' (feudal system) in history. Teachers might discuss the 'sistema de avaliação' (grading system) at the start of a semester. It is a foundational word for academic literacy.

O professor explicou o funcionamento do sistema respiratório.

Este sistema de ensino é focado na prática.

O sistema de som do cinema é incrível.

In summary, 'sistema' is not just a technical term; it is a word that bridges the gap between science, technology, politics, and everyday frustrations. Listening for it in podcasts, news broadcasts, and daily conversations will help you understand how Portuguese speakers categorize and describe the organized world around them.

The most frequent mistake learners make with sistema is treating it as a feminine noun. This is an understandable error because about 90% of Portuguese nouns ending in 'a' are feminine. However, 'sistema' belongs to a specific group of words of Greek origin that are masculine.

Gender Error: Saying 'a sistema' or 'esta sistema' is incorrect. You must always use 'o sistema' or 'este sistema'. This also applies to plural forms: 'os sistemas' (correct) vs 'as sistemas' (incorrect).

Errado: A sistema está com problemas.
Correto: O sistema está com problemas.

Adjective Misalignment: Learners often use feminine adjectives with 'sistema'. For example, saying 'sistema nova' instead of 'sistema novo'. Remember that the adjective must agree with the masculine gender of the noun, regardless of its ending.

Errado: Precisamos de uma sistema moderna.
Correto: Precisamos de um sistema moderno.

Pronunciation Pitfalls: In European Portuguese, the first 'e' in 'sistema' is often reduced or almost silent, sounding like 's'stema'. In Brazilian Portuguese, it is more clearly pronounced as 'sis-TE-ma'. English speakers sometimes over-emphasize the 'i' sound, making it sound like 'see-stema', which is slightly off. The 's' in the middle is unvoiced (like 'snake'), not voiced (like 'zebra').

Pronuncie: sis-TE-ma (com o 's' chiado ou seco, dependendo da região).

Evite: zee-stema (o 's' não tem som de 'z').

Evite: a sistema (sempre use o artigo masculino).

Another mistake is using 'sistema' when 'aparelho' (device) or 'equipamento' (equipment) is more appropriate. While a sound system is 'sistema de som', a single speaker is an 'alto-falante' or 'caixa de som'. Understanding the scope of the word—that it refers to a collection of parts—will help you use it more naturally.

While sistema is a very broad term, Portuguese offers several alternatives depending on the specific context. Choosing the right word can make your speech sound more sophisticated and precise.

Método vs. Sistema: 'Método' refers to a specific way of doing something, a technique or a process. 'Sistema' is broader and usually implies a larger structure. You might use a 'método de estudo' (study method) within an 'sistema educacional' (educational system).

Qual é o seu método para aprender vocabulário?

Regime vs. Sistema: 'Regime' is often used for political systems, specifically those that are authoritarian or have a specific governing style (e.g., 'regime militar'). It can also refer to a diet or a strict routine ('regime alimentar'). 'Sistema' is more neutral.

O país viveu sob um regime democrático por décadas.

Processo vs. Sistema: 'Processo' refers to a series of actions or steps taken to achieve an end. A 'sistema' often contains many 'processos'. For example, 'O processo de inscrição no sistema é simples' (The registration process in the system is simple).

Precisamos agilizar o processo de produção.

A organização da empresa é impecável.

O mecanismo do relógio parou de funcionar.

Other words like 'aparelho' (for biological systems like 'aparelho digestivo', though 'sistema' is also used) and 'esquema' (for a diagram or a 'scheme') are also useful. 'Esquema' is often used informally in Brazil to mean a 'plan' or 'setup'. By learning these nuances, you can avoid overusing 'sistema' and express yourself with greater clarity.

How Formal Is It?

豆知識
