解説 nadar in your Level:

At the A1 level, 'nadar' is introduced as a basic action verb used to describe hobbies and abilities. Learners focus on the present tense (eu nado, você nada) and the simple infinitive. The primary goal is to be able to say whether you like to swim, where you swim (pool or beach), and ask others if they know how to swim. Vocabulary is centered around 'piscina', 'praia', and 'mar'. At this stage, the focus is on literal meaning and simple sentence structures like 'Eu gosto de nadar'. Beginners also learn the basic distinction between 'saber nadar' (having the skill) and 'nadar' (the action). It is essential for forming basic 'about me' profiles and participating in introductory conversations about leisure activities.

At the A2 level, students expand their use of 'nadar' into the past and future tenses. They learn to describe past experiences, such as 'Ontem eu nadei no mar', using the Pretérito Perfeito. They also start using the Pretérito Imperfeito to describe habitual actions in the past: 'Quando eu era criança, eu nadava todos os dias'. The use of prepositions becomes more accurate, distinguishing between 'nadar em' for location and 'nadar para' for direction. Learners begin to understand simple compound sentences and can describe their swimming routines in more detail, including the frequency and with whom they participate in the activity. Basic health benefits of swimming might also be discussed.

At the B1 level, 'nadar' is used in more complex grammatical structures, including the conditional and the subjunctive mood. For example, 'Se eu tivesse uma piscina, eu nadaria mais' or 'Minha mãe quer que eu nade com cuidado'. Learners can participate in longer discussions about the benefits of swimming for physical and mental health. They also begin to encounter common idiomatic expressions like 'nadar contra a maré' and 'nadar em dinheiro', understanding their metaphorical meanings in context. The vocabulary broadens to include different swimming strokes and more specific aquatic environments. Students can recount detailed stories involving swimming, such as a vacation mishap or a successful race.

At the B2 level, 'nadar' is used fluently in a variety of contexts, including professional and abstract ones. Learners can debate topics like the environmental impact of swimming in natural habitats or the ethics of competitive sports. They are comfortable with the personal infinitive ('Para nós nadarmos bem, precisamos de treino') and can use the verb in formal writing. Idiomatic usage becomes more natural, and the nuances between 'nadar', 'mergulhar', and 'flutuar' are clearly understood and applied. B2 students can also understand more complex media, such as sports documentaries or news reports about swimming championships, without much difficulty. They can express subtle differences in meaning, such as the difference between a casual 'mergulho' and a serious 'sessão de natação'.

At the C1 level, learners use 'nadar' with full linguistic flexibility, often employing it in sophisticated literary or rhetorical ways. They can appreciate the use of 'nadar' in Portuguese literature and poetry, where it might represent themes of existentialism or the passage of time. The verb is used effortlessly in all moods and tenses, including the more obscure ones like the Pluperfect. C1 speakers can use 'nadar' to describe complex social phenomena metaphorically, such as 'nadar num mar de burocracia'. They have a deep understanding of regional variations in how swimming-related terms are used across the Lusophone world, from Portugal to Angola to Brazil, and can adapt their register accordingly.

At the C2 level, 'nadar' is just one tool in a vast arsenal of expression. A C2 speaker can use the verb with the precision of a native, including all its technical, metaphorical, and idiomatic nuances. They can engage in high-level philosophical discussions where 'nadar' serves as a metaphor for human agency or flow. Their understanding of the word's etymology from the Latin 'natare' and its historical evolution in the Portuguese language adds depth to their usage. They can write complex essays or deliver speeches where 'nadar' is used to evoke specific cultural imagery or emotional responses. At this level, the distinction between the learner and the native speaker is virtually non-existent in the use of this foundational verb.

nadar 30秒で

Nadar is the Portuguese verb for 'to swim', used for both people and animals.
It is a regular -ar verb, making it easy to conjugate in all tenses.
Commonly used with the preposition 'em' (in) to indicate the body of water.
Beyond the literal, it features in several common idioms about wealth and effort.

The Portuguese verb nadar is a fundamental action verb that translates directly to the English 'to swim'. At its most basic level, it describes the physical act of moving through water by using one's limbs, whether for recreation, survival, or sport. However, in the Lusophone world, the act of swimming carries deep cultural significance, particularly in Brazil and Portugal, where the coastline plays a central role in daily life and national identity.

Physical Action: The literal use of nadar refers to any stroke, such as 'crawl' (livre), 'peito' (breaststroke), 'costas' (backstroke), or 'mariposa' (butterfly).
Recreational Context: Used when going to the 'piscina' (pool) or 'praia' (beach) to enjoy the water without necessarily being a professional athlete.
Metaphorical Usage: Commonly used in idioms like 'nadar em dinheiro' (to swim in money) to indicate abundance or wealth.

As crianças adoram nadar no mar durante as férias de verão.

(The children love to swim in the sea during the summer holidays.)

In terms of frequency, nadar is an A1 level word because it is essential for describing hobbies and basic physical abilities. You will encounter it in childhood stories, travel brochures, and fitness conversations. It is a regular '-ar' verb, making it one of the easiest verbs for English speakers to conjugate early in their Portuguese learning journey. Beyond the literal, it signifies a sense of freedom and connection with nature, especially in coastal cities like Rio de Janeiro or Lisbon, where 'ir nadar' is a common social invitation.

Eu nado mil metros todos os dias para manter a forma.

(I swim a thousand meters every day to stay in shape.)

Furthermore, the word appears in several proverbs that reflect the Portuguese-speaking world's historical relationship with the sea. For instance, the phrase 'nadar, nadar e morrer na praia' illustrates the frustration of working hard toward a goal only to fail at the very last moment. This shows how 'nadar' is deeply embedded in the collective psyche as more than just a physical movement but a metaphor for life's struggles and efforts.

Ele está nadando contra a maré ao tentar mudar as regras da empresa.

(He is swimming against the tide by trying to change the company's rules.)

In a professional or academic context, 'nadar' might be used to describe the locomotion of aquatic organisms in biology or the fluid dynamics in physics. However, for most learners, the focus remains on personal ability. Questions like 'Você sabe nadar?' (Do you know how to swim?) are standard icebreakers in summer settings. The verb is versatile, emotive, and foundational for anyone looking to navigate Portuguese conversations about health, travel, or sports.

Using nadar correctly involves understanding its conjugation as a regular '-ar' verb and knowing which prepositions typically accompany it. Because it is an intransitive verb (it doesn't require a direct object to make sense), it is often followed by prepositional phrases that indicate location or manner.

Preposition 'em': Used to specify the body of water. Example: 'Nadar no (em + o) rio' or 'Nadar na (em + a) piscina'.
Preposition 'para': Used to indicate a destination or purpose. Example: 'Nadar para a margem' (Swim to the shore).
Adverbial Modification: Used to describe the quality of the action. Example: 'Nadar depressa' (to swim fast) or 'Nadar suavemente' (to swim smoothly).

Nós nadamos no lago ontem à tarde.

(We swam in the lake yesterday afternoon.)

Conjugation is straightforward. In the present tense, it follows the pattern: *eu nado*, *você nada*, *nós nadamos*, *vocês nadam*. In the past (Pretérito Perfeito), it becomes: *eu nadei*, *você nadou*, *nós nadamos*, *vocês nadaram*. Note that 'nós nadamos' is identical in both the present and the past in Brazilian Portuguese, so context is key to determining the time frame. In European Portuguese, the past form 'nadámos' uses an accent to distinguish it.

Se eu tivesse tempo, nadaria todos os fins de semana.

(If I had time, I would swim every weekend.)

For more advanced usage, the personal infinitive (infinitivo pessoal) is common. For example, 'É importante nós nadarmos com segurança' (It is important that we swim safely). Also, consider the reflexive use, though rare, 'nadar-se' is not used; instead, we use 'banhar-se' for bathing. 'Nadar' is always about the action of propulsion. In the future tense, 'Eu vou nadar' is more common in spoken Portuguese than the formal 'Nadarei'.

Eles estão nadando na direção errada.

(They are swimming in the wrong direction.)

When describing a scene, the imperfect tense (*Pretérito Imperfeito*) is used for ongoing actions in the past: 'Enquanto eu nadava, vi um golfinho' (While I was swimming, I saw a dolphin). This tense is essential for storytelling and setting the stage in narratives. Mastery of these patterns allows the speaker to describe everything from a simple workout to a complex aquatic adventure with precision and natural flow.

The word nadar is ubiquitous in any setting involving water. In Brazil, with over 7,000 kilometers of coastline, the beach is a second home for many, and 'nadar' is a daily topic of conversation. You will hear it in casual settings, sports news, and even in safety warnings.

At the Beach (Na Praia): Lifeguards might shout 'Não nade longe da costa!' (Don't swim far from the shore!) to ensure safety against rip currents.
Sports Commentary: During the Olympics or Pan-American Games, commentators will discuss how an athlete 'nada com perfeição' (swims with perfection).
Health and Fitness: Doctors often recommend 'nadar' as a low-impact exercise for patients with joint issues or back pain.

O salva-vidas recomendou não nadar aqui devido às correntes fortes.

(The lifeguard recommended not swimming here due to strong currents.)

In popular culture, 'nadar' appears in many Brazilian 'música popular brasileira' (MPB) songs, often symbolizing freedom, cleansing, or the vastness of life. It’s also heard in children's songs like 'O Peixinho', which teaches kids about the movements of fish. In schools, 'aulas de natação' (swimming lessons) are a common extracurricular activity, so parents and teachers use the word frequently when discussing schedules and progress.

Você ouviu que o campeão vai nadar na prova de amanhã?

(Did you hear that the champion is going to swim in tomorrow's race?)

Furthermore, in the business world, you might hear 'nadar' used metaphorically during strategy meetings. A manager might say a company is 'nadando em águas calmas' (swimming in calm waters) to indicate a period of stability, or 'nadando com tubarões' (swimming with sharks) to describe a highly competitive and dangerous market environment. This versatility ensures that whether you are on a surfboard in Nazaré or in a boardroom in São Paulo, the word 'nadar' will be part of the linguistic landscape.

Muitos peixes costumam nadar perto dos corais.

(Many fish usually swim near the corals.)

Finally, social media is full of 'nadar'. Instagram captions for vacation photos often feature 'nadando no paraíso' (swimming in paradise) or 'apenas nadar' (just swimming). The word is evocative of relaxation and the quintessential 'férias' (vacation) vibe. Thus, hearing 'nadar' usually brings a sense of positivity, activity, or natural beauty to the listener's mind.

Even though nadar is a regular verb, English speakers often stumble on specific nuances and prepositional choices. Understanding these common pitfalls will help you sound more like a native speaker and avoid confusion in aquatic contexts.

Confusion with 'Banhar-se' or 'Tomar Banho': In English, 'to go for a swim' can sometimes mean just getting in the water. In Portuguese, 'nadar' specifically implies the action of swimming strokes. If you just want to say you are going into the water to cool off, use 'entrar na água' or 'se refrescar'.
Preposition Errors: Learners often say 'nadar para a piscina' when they mean they are swimming *in* the pool. Remember: 'em' (no/na) for the location, and 'para' for the destination.
Saber vs. Poder: To express ability, use 'saber'. 'Eu não sei nadar' means you don't have the skill. 'Eu não posso nadar' means you have the skill but are currently prevented (e.g., the pool is closed).

Errado: Eu posso nadar muito bem. (Unless you mean you are allowed to).

(Correct: Eu sei nadar muito bem.)

Another frequent error involves the past tense of 'nadar' in European Portuguese. Portuguese learners often forget the accent in 'nadámos' (we swam), which distinguishes it from the present 'nadamos' (we swim). In Brazil, they sound the same, but in Portugal, the 'á' is open and the 'a' is closed. Neglecting this pronunciation/spelling difference can lead to confusion in written European Portuguese.

Errado: Eu gosto de nadar no mar para a praia.

(Correct: Eu gosto de nadar do mar para a praia / I like to swim from the sea to the beach.)

Lastly, be careful with the verb 'mergulhar'. While in English we might say 'I'm going for a swim' and then jump in, 'mergulhar' specifically means to dive or submerge. If you tell someone 'Eu vou nadar', they expect to see you moving across the surface. If you say 'Eu vou mergulhar', they expect to see you go underwater. Misusing these can lead to safety misunderstandings, especially in deep or murky waters.

Eu nadei ontem, não 'nadou'.

(Remember to match the verb ending to the subject: 'I swam' vs 'He swam'.)

Avoid overcomplicating the verb. Since it is regular, many students try to find irregularities where there are none. Stick to the basic '-ar' endings and you will be correct 99% of the time. The biggest challenge isn't the verb itself, but the surrounding vocabulary like 'touca' (swim cap), 'óculos de natação' (goggles), and 'sunga' (men's swim trunks in Brazil), which are essential for a complete conversation about swimming.

While nadar is the most common verb for moving in water, Portuguese offers a rich palette of related verbs that provide more specific details about the action or the context. Choosing the right one can make your speech more precise and natural.

Mergulhar: To dive or submerge. Use this when the action involves going underwater or jumping from a height. Example: 'Mergulhar de cabeça' (To dive headfirst).
Boiar: To float. This is the opposite of 'afundar' (to sink) and implies staying on the surface without active swimming strokes.
Flutuar: Similar to 'boiar', but often used in more poetic or scientific contexts. Objects 'flutuam' in space or water.
Banhar-se: To bathe or take a dip. Often used in literary contexts or to describe a casual, non-athletic interaction with water.

Em vez de nadar, eu prefiro apenas boiar e relaxar.

(Instead of swimming, I prefer to just float and relax.)

In a competitive sense, you might use 'disputar uma prova de natação' (to compete in a swimming race) instead of just 'nadar'. If you are talking about crossing a body of water, 'atravessar a nado' (to cross by swimming) is a more descriptive phrase. For instance, 'Ele atravessou o canal a nado' (He swam across the channel).

O pato nada calmamente no lago.

(The duck swims calmly in the lake.)

For those learning Portuguese for travel, knowing 'chapiscar' or 'brincar na água' (to play in the water) can be useful when describing children's activities. If you are talking about professional swimming, you'll need the names of the strokes: 'nado livre', 'nado de costas', 'nado de peito', and 'nado borboleta'. This adds a layer of technical proficiency to your vocabulary.

É perigoso nadar onde os barcos estão navegando.

(It is dangerous to swim where boats are sailing.)

Finally, consider the verb 'chapinhar', which means to splash or paddle about in shallow water. It is a very common word to use when talking about toddlers or puppies at the beach. By diversifying your water-related verbs, you move beyond the basic A1 level and start expressing the nuances of your experiences in the Portuguese-speaking world.

ヒント

Master the -ar endings

Since 'nadar' is regular, use it as a model for other -ar verbs like 'falar' or 'andar'. Once you know how to conjugate 'nadar', you know hundreds of other verbs.

Learn aquatic nouns

Pair 'nadar' with nouns like 'touca' (cap), 'óculos' (goggles), and 'prancha' (board) to expand your ability to talk about the activity.

Use 'Mergulho' casually

In Brazil, if someone invites you to 'dar um mergulho', they mean go for a quick swim. It's more common than saying 'vamos nadar' in social settings.

Understand warnings

Look for signs that say 'Proibido nadar' (Swimming prohibited) or 'Perigo' (Danger) on beaches to stay safe.

Money Metaphor

Stress the end

Always stress the 'dar' part of 'nadar'. If you stress the 'na', it sounds like you are saying 'nothing' (nada).

Pool vs Sea

Remember that 'piscina' is feminine (na piscina) and 'mar' is masculine (no mar). Getting these right makes you sound much more fluent.

Yes, 'nadar' is a completely regular -ar verb in all tenses. This makes it very easy for students to learn. For example, in the present: nado, nadas, nada, nadamos, nadais, nadam.

You say 'Eu gosto de nadar'. Remember to always include the preposition 'de' after the verb 'gostar' when followed by an infinitive.

'Nadar' is the verb (the action), while 'natação' is the noun (the sport or the activity). For example: 'Eu nado' (I swim) vs 'Eu pratico natação' (I practice swimming).

Yes, 'nadar' is used for fish, dogs, ducks, and any other animal that moves through water using limbs or fins. 'O peixe nada' is a perfect sentence.

Usually 'em' (no, na, nos, nas) for locations like 'no mar' or 'na piscina'. You use 'para' for directions like 'nadar para a margem'.

You can use the phrase 'atravessar a nado'. For example: 'Ele atravessou o rio a nado' (He swam across the river).

Yes, metaphorically. 'Nadar em dinheiro' means to be very rich, and 'nadar contra a maré' means to go against the market trends.

The conjugation is mostly the same, but the 1st person plural past has an accent: 'nadámos' (past) vs 'nadamos' (present). In Brazil, both are 'nadamos'.

The main styles are: nado livre (crawl), nado de costas (backstroke), nado de peito (breaststroke), and nado borboleta (butterfly).

You can say 'Vou nadar' or 'Vou dar um mergulho'. The latter is very common in Brazil for a casual swim.
