解説 expirar in your Level:

At the A1 level, you primarily learn 'expirar' in the context of very basic physical actions, often in contrast with 'inspirar' (to breathe in). You might encounter it in a simple gym class or a basic health context. At this stage, you don't need to worry about complex tenses. Just focus on the infinitive and the simple present. For example, 'Eu respiro: eu inspiro e eu expiro'. It's important to recognize the word when someone is giving you instructions on how to relax or during a simple doctor's visit. You are learning that 'ex-' often means 'out', which helps you remember that this word means 'breathing out'. You might also see it on a very simple website notice like 'A sessão acabou' (The session ended), though 'expirou' might still be a bit advanced. Focus on the physical sensation of the word first.

As an A2 learner, you start to see 'expirar' used for time, but in very concrete ways. You might notice it on a digital coupon or a simple app notification: 'O código vai expirar'. You are beginning to understand that some words have more than one meaning. You should be able to conjugate 'expirar' in the present and the simple past (Pretérito Perfeito). For example, 'O prazo expirou ontem' (The deadline expired yesterday). You are also learning to distinguish it from 'vencer' in basic contexts. You know that 'vencer' is for your milk and 'expirar' is for your internet session. You might also hear it in more detailed health instructions, like 'Expire devagar' (Exhale slowly). Your vocabulary is expanding to include these technical end-points of time.

At the B1 level, you are expected to use 'expirar' with confidence in both its physical and administrative senses. You understand the nuances of when to use it versus 'vencer' or 'terminar'. You can use it in complex sentences with conjunctions, such as 'Embora o prazo tenha expirado, eu consegui enviar o documento' (Although the deadline has expired, I managed to send the document). You are familiar with the noun 'expiração' and can use the word in professional settings, like explaining why a software license needs renewal. You also use it correctly in fitness or wellness contexts without confusing it with 'inspirar'. This is the level where the word becomes a functional part of your professional and personal vocabulary, allowing you to navigate bureaucratic and health-related conversations in Portuguese-speaking environments.

At the B2 level, 'expirar' is a word you use effortlessly. You understand its role in formal documents, legal contracts, and medical reports. You can discuss the implications of an 'expirado' status (expired status) on a visa or a contract. You are also aware of the phonological variations of the 'x' in different Portuguese-speaking regions. You might use the word in more abstract ways, such as discussing the 'expiração' of a political era or a specific trend, though this is bordering on C1. You are comfortable using the future subjunctive and other complex moods: 'Quando o prazo expirar, teremos que agir' (When the deadline expires, we will have to act). Your use of the word reflects a deep understanding of Portuguese register, knowing exactly when 'expirar' sounds more appropriate than its synonyms.

For C1 learners, 'expirar' takes on a more literary and precise character. You recognize its use in classical literature as a euphemism for death ('Ele expirou nos braços da amada'). You understand the etymological connection to other 'spirit' words like 'espírito', 'conspirar', and 'suspirar'. You can use 'expirar' in highly formal writing, such as legal briefs or academic papers, to describe the cessation of rights or the end of a physiological process with technical precision. You are also sensitive to the rhythmic and poetic qualities of the word in prose. Your vocabulary is so rich that you choose 'expirar' specifically for its formal and precise connotations, distinguishing it from the more mundane 'acabar' or 'vencer' with stylistic intent.

練習する例文メモとヒント

expirar 30秒で

Expirar means to exhale air from the lungs, the opposite of inhaling.
It also refers to the end of a deadline, license, or digital session.
For food and bills, 'vencer' is more common than 'expirar' in daily life.
It is a regular '-ar' verb, making it easy to conjugate in all tenses.

The Portuguese verb expirar is a sophisticated and versatile term that primarily functions in two distinct semantic realms: the physiological act of breathing and the chronological act of reaching a deadline. At its core, the word is derived from the Latin expirare, where 'ex-' means 'out' and 'spirare' means 'to breathe'. In a physical sense, it refers to the process of releasing air from the lungs, which is the essential counterpart to inspirar (to inhale). This usage is common in medical, athletic, and wellness contexts, such as during a yoga session or a medical examination where a doctor might instruct a patient to breathe out slowly to listen to their lungs.

Physiological Context: In biology and health, expirar is the technical term for exhalation. It is used when discussing respiratory rates, lung capacity, or relaxation techniques. For example, 'Ao meditar, você deve expirar lentamente pelo nariz' (When meditating, you should exhale slowly through the nose).
Temporal/Legal Context: Beyond breathing, the word is widely used to describe the end of a validity period. This applies to legal documents, digital sessions, contracts, and deadlines. While 'vencer' is often used for food expiration, expirar is the standard for technical and official expirations. For instance, 'O seu passaporte vai expirar no próximo mês' (Your passport will expire next month).

O instrutor pediu para todos expirarem profundamente após o exercício.

Translation: The instructor asked everyone to exhale deeply after the exercise.

Understanding the nuance between the physical and the abstract is key for B1 learners. When you are at a pharmacy or a supermarket, you might see the 'data de validade' (expiry date). While the verb 'vencer' is used for the milk going bad, 'expirar' is the preferred term when a software license or a promotional code reaches its end. It carries a slightly more formal tone than 'acabar' or 'terminar'. In the digital age, you will frequently encounter this word in error messages: 'A sua sessão expirou por inatividade' (Your session has expired due to inactivity). This dual nature makes it a high-frequency word in both professional environments and health-conscious social circles.

Lamentamos informar que o seu contrato de arrendamento irá expirar em trinta dias.

Translation: We regret to inform you that your lease agreement will expire in thirty days.

Finally, there is a third, more poetic and archaic meaning: to die or to breathe one's last breath. While you won't hear this in daily conversation, you might encounter it in classical Portuguese literature or formal obituaries. In this context, it is a euphemism for 'falecer' (to pass away). For a B1 learner, focusing on the 'breathing out' and 'deadline' meanings will cover 99% of your needs. Remember that the conjugation follows the regular '-ar' pattern, making it relatively simple to use once you grasp the contexts.

Using expirar correctly requires identifying whether you are describing a physical action or a temporal limit. Because it is a regular verb, it provides a stable foundation for learners to practice various tenses. Let's explore how it functions across different grammatical structures and contexts to ensure you can use it naturally in conversation and writing.

Direct Physical Action: When used to mean 'to exhale', it is often paired with adverbs like 'lentamente' (slowly), 'profundamente' (deeply), or 'totalmente' (completely). It describes the mechanics of breathing. Example: 'Inspire pelo nariz e expire pela boca' (Inhale through the nose and exhale through the mouth).
Abstract Temporal Action: When referring to time, the subject is usually an inanimate object like a 'prazo' (deadline), 'cartão' (card), or 'oferta' (offer). Example: 'Esta promoção vai expirar à meia-noite' (This promotion will expire at midnight).

É necessário expirar todo o ar antes de mergulhar na piscina.

Translation: It is necessary to exhale all the air before diving into the pool.

In formal documents, you might see the noun form 'expiração' or the past participle 'expirado'. For example, 'O prazo de validade está expirado' (The validity period is expired). However, in spoken Portuguese, using the verb in the past tense is more common: 'O prazo já expirou'. Note that when talking about breathing, we rarely use the past participle unless describing a completed medical test.

Se você não renovar a assinatura, o acesso irá expirar automaticamente.

Translation: If you do not renew the subscription, access will expire automatically.

When practicing, try to construct sentences that contrast the two meanings. This helps solidify the word's flexibility in your mind. For example: 'Enquanto eu esperava o meu visto expirar, eu tentava expirar calmamente para não ficar ansioso' (While I was waiting for my visa to expire, I tried to exhale calmly so as not to get anxious). This double usage showcases your command of the B1 level vocabulary.

The context in which you encounter expirar largely determines its meaning. It is a word that bridges the gap between the intimate act of living (breathing) and the structured world of bureaucracy and technology. Here are the primary environments where this word is part of the daily soundscape.

At the Gym or Yoga Studio: Fitness instructors constantly use this word. You will hear phrases like 'Inspire ao subir, expire ao descer' (Inhale on the way up, exhale on the way down). It is the rhythm of the workout.
In Technical Support and Apps: Modern technology is perhaps the most common place to see this word today. Banking apps, streaming services, and corporate logins use it to manage security. 'O seu token de segurança vai expirar em 30 segundos' (Your security token will expire in 30 seconds).
At the Doctor's Office: During a physical exam, a physician will say: 'Respire fundo... agora expire devagar' (Breathe deeply... now exhale slowly). It is essential for checking lung health and heart rhythms.

Atenção: sua senha temporária irá expirar em breve. Por favor, altere-a agora.

Translation: Attention: your temporary password will expire soon. Please change it now.

You will also hear it in the news when discussing international treaties or political mandates. Journalists might report, 'O mandato do presidente deve expirar no final do ano' (The president's mandate is set to expire at the end of the year). This usage is very formal and conveys a sense of official finality.

Não se esqueça de expirar o ar completamente durante o teste de espirometria.

Translation: Don't forget to exhale the air completely during the spirometry test.

In summary, expirar is a word of transitions. Whether it is the transition of air leaving your body or the transition of a document from valid to invalid, it marks a point of completion. Pay attention to your surroundings: the next time you are at an airport or using a Portuguese-language app, you are almost certain to see or hear this verb in action.

While expirar is a cognate of the English 'expire', its usage in Portuguese has specific boundaries that can trip up even advanced learners. The most frequent errors involve confusing it with its antonym, using it for the wrong types of objects, or mispronouncing the tricky 'x'.

Confusion with 'Inspirar': Because they sound similar and are always taught together, students often swap them. Remember: Inspirar = Air In. Expirar = Air Exit. Using 'expirar' when you mean to breathe in can be confusing in a medical or fitness context.
Misuse with Food Products: In English, we say 'the milk expired'. In Portuguese, while 'o leite expirou' is technically understood, it sounds very clinical or 'translated'. Native speakers almost always use 'vencer'. Say: 'O leite venceu'. Use expirar for documents, sessions, and breathing.

Errado: Eu preciso inspirar o ar para fora dos pulmões.
Correto: Eu preciso expirar o ar dos pulmões.

Correction: You exhale (expirar) air out, you don't 'inhale it out'.

Another common mistake is the pronunciation of the 'x'. In 'expirar', the 'x' is followed by a consonant ('p'). In this position, it should never be pronounced like a 'z' or an 'ks' (like 'taxi'). It should be a soft 's' (like 'stay') or a 'sh' (like 'show') depending on the dialect. Pronouncing it as 'ek-spirar' sounds very foreign and can make the word hard to recognize for natives.

Errado: O meu iogurte vai expirar amanhã.
Correto: O meu iogurte vai vencer amanhã.

Correction: Use 'vencer' for perishable goods.

Finally, avoid using expirar to mean 'to finish' a task. You don't 'expirar' your homework. You 'terminar' or 'concluir' it. Expirar is about the passage of time reaching a limit set by someone else (a system, a law, or nature), not about your own completion of an action. Keep these distinctions in mind to sound more like a native speaker.

To truly master expirar, you must understand its neighbors in the Portuguese language. Several words share its semantic space, but each has a specific 'flavor' or register that makes it more suitable for certain situations. Let's compare expirar with its closest relatives.

Expirar vs. Vencer: While both mean 'to reach an end date', vencer is the everyday choice for food, bills, and competitions. Expirar is reserved for technical, digital, and official contexts. You pay a bill that venceu, but you renew a session that expirou.
Expirar vs. Soprar: Soprar means 'to blow'. While expirar is the biological process of moving air out, soprar is the intentional act of directing air at something (like candles). You expira to relax; you sopra to cool down soup.
Expirar vs. Exalar: Exalar is more poetic or related to scents. A flower exala a perfume. While it can mean to breathe out, it suggests the air carries something with it (a smell or an emotion). Expirar is the neutral, functional term.

O prazo para a inscrição expirou, mas você ainda pode tentar no próximo ano.

Translation: The deadline for registration has expired, but you can still try next year.

In literary contexts, you might find findar or terminar. These are broader verbs meaning 'to end'. Findar is particularly beautiful and often used in poetry to describe the end of a day or a life. However, in a B1 conversation, expirar remains your best bet for technical deadlines and breathing.

As flores exalam um perfume doce, enquanto nós expiramos o ar puro do jardim.

Translation: The flowers exhale a sweet perfume, while we exhale the fresh air of the garden.

By diversifying your vocabulary with these alternatives, you avoid repetition and show a deeper understanding of Portuguese nuances. Just remember that expirar is the 'gold standard' for precision in its two main domains: the lungs and the clock.

How Formal Is It?

豆知識

The word 'expirar' and 'espírito' (spirit) come from the same root because ancient cultures believed that life was literally the breath inside the body. When you 'expirava' for the last time, your 'espírito' left the body.

発音ガイド

UK /eʃ.pi.ˈɾaɾ/

US /is.pi.ˈɾaχ/

The stress is on the last syllable: ex-pi-RAR.

よくある間違い

Pronouncing 'x' like 'ks' (as in 'taxi'). In 'expirar', it's always 's' or 'sh'.
Confusing it with 'espirrar' (to sneeze). 'Expirar' has a single 'r' sound, while 'espirrar' has a strong 'rr'.
Stressing the second syllable (ex-PI-rar). The stress must be on the end.
Making the 'e' too long like 'eee-spirar'. It should be a neutral vowel.
