Practice it Examples Notes & Tips vigor in 30 Seconds

Explanation vigor in your Level:

At the A1 level, you are just starting your journey with Portuguese. You might not use the word 'vigor' yourself very often, as it is a bit more advanced than words like 'força' (strength) or 'energia' (energy). However, it is good to know that 'vigor' means someone is very healthy and has a lot of energy. Think of a superhero or a very active grandfather. If you see 'vigor' in a simple book, imagine a battery that is 100% full. You can remember it because it looks like the English word 'vigour'. For now, focus on the idea that 'vigor' is a 'big' word for 'strength'. If you see a picture of a strong athlete, you could say they have 'vigor'. It is a masculine word, so you say 'o vigor'. Don't worry about the legal meanings yet; just think of it as a fancy way to say someone is strong and healthy. You might hear it in a song or a simple story about a brave knight. Just remember: vigor = strength + health. It's a positive word! If you have vigor, you can run fast and play for a long time without getting tired. It's like having a 'superpower' of health. In A1, you mostly learn words for things you can see, and 'vigor' is something you see when someone is full of life and moving with a lot of energy.

As an A2 learner, you are building more sentences and starting to understand more complex ideas. You can start using 'vigor' to describe people or actions more precisely than just using 'bom' (good) or 'forte' (strong). For example, if you are talking about your favorite sport, you can say 'Eu jogo futebol com vigor' (I play soccer with vigor). This sounds better than just saying 'Eu jogo bem'. At this level, you should also be aware that 'vigor' is used in the news. You might hear the phrase 'em vigor'. This is very important! It means a rule is working right now. If your teacher says a new rule is 'em vigor', you must follow it. It's like saying the rule is 'alive'. You can also use it to describe nature. If you have a garden, you could say 'As flores crescem com vigor' (The flowers grow with vigor). This means they are healthy and growing fast. Remember that 'vigor' is a noun. If you want to describe a person as an adjective, you can use 'vigoroso' (for a man) or 'vigorosa' (for a woman). So, you can have 'vigor' (noun) or be 'vigoroso' (adjective). This helps you make your descriptions more interesting. You are moving beyond the basic words and starting to sound more like a real Portuguese speaker by using words that have both a physical and a more formal meaning.

At the B1 level, you are becoming an independent user of the language. You should now be comfortable using 'vigor' in both its physical and legal contexts. You should know the common phrase 'entrar em vigor'. This is essential for understanding news reports or workplace announcements. For example, 'O novo horário de trabalho entra em vigor na segunda-feira' (The new work schedule takes effect on Monday). You understand that 'vigor' is not just about being strong, but about being 'in force' or 'effective'. You can also use 'vigor' to add nuance to your descriptions of people's characters. Instead of just saying someone is 'trabalhador' (hardworking), you can say they 'trabalham com um vigor invejável' (they work with an enviable vigor). This shows a higher level of vocabulary. You should also start to notice the difference between 'vigor' and 'energia'. You know that 'energia' is what you get from food or coffee, but 'vigor' is a more permanent state of being robust and healthy. If someone has 'vigor', they are not just energetic for a moment; they have a strong constitution. You are also beginning to see 'vigor' in more abstract contexts, like 'o vigor de uma ideia' (the vigor of an idea) or 'o vigor da economia' (the vigor of the economy). This helps you participate in more complex conversations about society and health. You are now able to use this word to express intensity and authority in your speech and writing.

At the B2 level, you have a solid grasp of the language and can use 'vigor' with confidence in professional and academic settings. You understand the subtle differences between 'vigor' and its synonyms like 'vitalidade', 'pujança', and 'robustez'. You know that 'vigor' is often the best choice for describing the active state of laws ('em vigor') and the sustained physical capacity of a person. You can use the word metaphorically to describe the impact of a piece of literature or the strength of an argument. For instance, 'A argumentação do autor carece de vigor' (The author's argument lacks vigor). This shows you can evaluate the quality of abstract things. You are also aware of the word family, using 'vigoroso', 'vigorosamente', and 'revigorar' (to reinvigorate) correctly. You might use 'revigorar' when talking about a vacation: 'As férias me ajudaram a revigorar minhas energias'. At this level, you can also handle more complex grammatical structures involving 'vigor', such as using it in the subject position of a sentence: 'O vigor com que ela defendeu sua tese impressionou a banca' (The vigor with which she defended her thesis impressed the committee). You are sensitive to the register of the word, knowing it is appropriate for formal reports, literary analysis, and serious discussions about health and law. You are no longer just translating from English; you are thinking in Portuguese and choosing 'vigor' because it is the most precise word for the situation.

As a C1 learner, you possess a high level of linguistic competence. You use 'vigor' with naturalness and precision, capturing all its stylistic nuances. You are well-versed in the legal implications of the term, distinguishing between 'estar em vigor' and 'ter vigência', and you can discuss the 'perda de vigor' of a law in a technical sense. In literary contexts, you recognize 'vigor' as a hallmark of certain writing styles, perhaps describing a poet's 'vigor expressivo' (expressive vigor). You are comfortable using the word in highly abstract ways, such as discussing the 'vigor intelectual' of a philosopher or the 'vigor cultural' of a specific historical period. You can also use it in sophisticated idiomatic expressions, such as 'em pleno vigor das faculdades mentais' (in full possession of one's mental faculties), which is often used in legal documents or formal biographies. Your use of 'vigor' contributes to a formal and authoritative tone in your writing. You understand the historical weight of the word, potentially connecting it to its Latin roots in an academic discussion. You can also use it to describe natural phenomena with a certain poetic flair, like 'o vigor das águas de uma catarata'. At this level, 'vigor' is a tool you use to add texture and depth to your language, allowing you to express complex ideas about strength, validity, and life with absolute clarity and stylistic variety.

At the C2 level, you have mastered Portuguese to the point where you can use 'vigor' with the same finesse as a highly educated native speaker. You are aware of the word's entire history and its various applications across different fields—from the most technical legal jargon to the most elevated poetic forms. You can use 'vigor' to make extremely fine distinctions; for example, you might contrast the 'vigor' of a physical performance with the 'fragilidade' of the performer's underlying health, or discuss how a law remains 'em vigor' despite having lost its 'eficácia social' (social effectiveness). You are comfortable using the word in all registers, from a formal speech at a national academy to a nuanced conversation about the 'vigor' of a particular vintage of wine. Your vocabulary includes rare and sophisticated related terms, and you can play with the word's connotations to achieve specific rhetorical effects. You might use 'vigor' in a critique of a political movement, analyzing its 'vigor inicial' versus its current 'estagnação'. You understand the rhythmic and phonetic qualities of the word and can place it in a sentence for maximum impact. At this level, 'vigor' is not just a word you know; it is a part of your linguistic identity, a term you can deploy with total precision, creativity, and cultural awareness in any possible context.

Practice it Examples Notes & Tips

vigor in 30 Seconds

Vigor means physical strength, vitality, and health in living beings.
In legal contexts, it signifies that a law or rule is currently active (em vigor).
It is a masculine noun used to describe intensity in actions or natural forces.
Commonly found in the phrase 'entrar em vigor', meaning 'to take effect'.

The Portuguese word vigor is a masculine noun that serves as a powerful pillar in both everyday conversation and formal documentation. At its core, it represents the concept of vitality, physical strength, and intense energy. When you describe someone as having 'vigor', you are not just saying they are strong; you are suggesting a holistic state of robust health and an active, spirited nature. However, the utility of 'vigor' extends far beyond the gym or the doctor's office. In Portuguese, it is the standard term used to describe the validity or the 'life' of a law, a contract, or a regulation. When a rule is 'em vigor', it means it is currently active and must be followed. This duality makes it an essential word for intermediate learners to master, as it bridges the gap between biological descriptions and legal or professional terminology.

Physical Vitality: Refers to the energy and strength of a living being. It is often used to describe the elderly who remain active or the impressive stamina of athletes. For example, 'Aos oitenta anos, ele ainda mantém o seu vigor juvenil' (At eighty, he still maintains his youthful vigor).
Legal Validity: Used in the phrase 'entrar em vigor' to indicate when a law or rule starts to be applied. It is the formal equivalent of 'coming into force' or 'becoming effective'.
Intensity of Action: Describes the force or passion with which an action is performed. 'Ela defendeu os seus ideais com vigor' (She defended her ideals with vigor) implies a high level of conviction and energy.

In a cultural context, Portuguese speakers often value 'vigor' as a sign of resilience. In a country like Brazil, where the climate can be demanding and the social landscape is dynamic, 'trabalhar com vigor' (working with vigor) is a common way to express dedication and hard work. In Portugal, the word might appear more frequently in formal news broadcasts discussing 'medidas em vigor' (measures in force) regarding public policy or economic shifts. Understanding 'vigor' requires recognizing that it is not just about raw power, but about the quality of being active and effective in whatever state the subject finds itself.

O novo regulamento de trânsito entrará em vigor a partir da próxima segunda-feira, afetando todos os motoristas da capital.

To use 'vigor' correctly, you must also be aware of its collocations. It is rarely used as a simple adjective (like 'vigorous'); instead, we use the noun 'vigor' with verbs like 'ter' (to have), 'manter' (to maintain), or 'perder' (to lose). If you want the adjective form, you would use 'vigoroso' or 'vigorosa'. The word carries a positive connotation when applied to health but a neutral, strictly functional one when applied to law. For instance, a 'lei em vigor' is neither good nor bad inherently; it is simply the law that is currently being enforced. Conversely, 'saúde e vigor' is a classic pairing in Portuguese literature and toast-making, symbolizing the peak of human well-being.

Apesar da idade avançada, a árvore frutífera ainda produzia com um vigor surpreendente a cada primavera.

Metaphorical Use: Can be applied to abstract concepts like an economy or a social movement. 'A economia recuperou o seu vigor' implies a return to growth and strength after a period of stagnation.

Finally, the word 'vigor' is deeply rooted in Latin ('vigere'), meaning 'to be lively' or 'to thrive'. This historical connection explains why it is used for both the thriving of a plant and the thriving of a legal decree. As you progress in your Portuguese journey, you will notice that 'vigor' is a sophisticated choice that adds precision to your descriptions of energy and authority. Whether you are reading a newspaper in Lisbon or talking to a personal trainer in Rio, 'vigor' is a word that commands respect and conveys a sense of enduring power.

Using 'vigor' effectively in Portuguese involves understanding its syntactic patterns and the specific verbs it likes to accompany. Because it is a noun, it often functions as the direct object of a sentence or as part of a prepositional phrase. Let's explore the most common structures. One of the most frequent uses is with the verb 'entrar'. The phrase entrar em vigor is the standard way to say a law or a new set of rules has started to apply. You will see this in news headlines almost daily. For example, 'A nova lei seca entra em vigor hoje' (The new prohibition law takes effect today). Here, 'vigor' represents the state of being active.

Structure: Verbo + Vigor: Common verbs include 'ter' (to have), 'demonstrar' (to demonstrate), 'recuperar' (to recover), and 'manter' (to maintain). 'Ele demonstra muito vigor físico durante os treinos' (He demonstrates much physical vigor during training sessions).
Structure: Com + Vigor: This functions as an adverbial phrase meaning 'vigorously'. 'As crianças brincavam com vigor no parque' (The children were playing with vigor in the park). It describes the intensity of the action.

Another crucial aspect is the use of 'vigor' in the context of health and vitality. It is often paired with adjectives like 'pleno' (full), 'juvenil' (youthful), or 'físico' (physical). When you say someone is in 'pleno vigor da idade', you are saying they are at the peak of their life, usually referring to someone in their 20s or 30s who is healthy and strong. This is a very common idiomatic expression in Portuguese literature and formal speech. It conveys a sense of completeness and power that 'energia' alone might not capture.

O sol brilhava com tanto vigor que era impossível caminhar sem proteção.

In formal writing, specifically in legal or administrative contexts, you will encounter the phrase 'estar em vigor'. This is slightly different from 'entrar em vigor'. While 'entrar' describes the moment of starting, 'estar' describes the ongoing state. 'O decreto anterior ainda está em vigor' (The previous decree is still in force). This is vital for navigating bureaucracy in Portuguese-speaking countries. If a document is no longer 'em vigor', it may be described as 'sem efeito' (without effect) or 'caducado' (expired).

Furthermore, 'vigor' can describe the intensity of natural phenomena or abstract forces. A storm can hit with 'vigor', or an argument can be presented with 'vigor'. In these cases, it emphasizes the impact and the strength of the delivery. 'O debate foi conduzido com vigor por ambos os candidatos' (The debate was conducted with vigor by both candidates). This usage highlights the mental or rhetorical energy involved, showing that 'vigor' is not limited to muscles and laws, but also applies to the mind and spirit.

Para vencer o campeonato, a equipe precisará de todo o seu vigor na fase final.

Common Collocations: - Vigor físico (Physical strength)
- Vigor intelectual (Mental sharpness)
- Em pleno vigor (In full force/strength)
- Perder o vigor (To lose steam/vitality)

Finally, remember that while 'vigor' is a noun, the related adjective 'vigoroso' is very common. You might hear 'um exercício vigoroso' (a vigorous exercise) or 'uma resposta vigorosa' (a vigorous response). However, sticking to the noun 'vigor' often provides a more classic, grounded feel to your Portuguese sentences. It suggests a deep-seated quality rather than just a temporary state of action. As you practice, try to swap 'energia' for 'vigor' in contexts where you want to sound more precise or formal.

If you are spending time in a Portuguese-speaking country, you will encounter 'vigor' in several distinct environments. The most frequent place is undoubtedly the news. Whether it is a television broadcast, a newspaper like 'Público' in Portugal or 'Folha de S.Paulo' in Brazil, or a digital news portal, 'vigor' is the go-to word for legal updates. Whenever the government announces a new policy—be it regarding taxes, environmental regulations, or public health measures—the reporter will inevitably say, 'As novas regras entram em vigor a partir de amanhã'. This context is so common that even people who don't work in law are intimately familiar with this specific usage.

The News and Politics: Journalists use 'vigor' to describe the status of legislation. It is a neutral, professional term that provides clarity on when citizens must begin complying with new rules.
Sports Commentary: Commentators often use 'vigor' to describe the performance of athletes, especially in sports requiring high endurance like football (soccer) or rowing. They might say a player 'perdeu o vigor no segundo tempo' (lost their vigor in the second half).

Another place you will hear 'vigor' is in medical or wellness contexts. Doctors, nutritionists, and fitness instructors use it to describe a patient's vitality. In a clinical setting, a doctor might note that an elderly patient has 'bom vigor físico para a idade' (good physical vigor for their age). In the wellness industry, supplements or diets are often marketed with the promise of 'devolver o vigor' (returning vigor) to the consumer. This taps into the word's association with youth, health, and a zest for life. It sounds more clinical and authoritative than 'energia', which can sometimes feel a bit vague or New Age.

O treinador exigiu que os jogadores mantivessem o vigor defensivo até o apito final do árbitro.

Literature and formal speeches also make heavy use of 'vigor'. If you attend a graduation ceremony or a formal dinner, the speakers might talk about the 'vigor da juventude' (the vigor of youth) or the 'vigor das ideias' (the vigor of ideas). In this context, the word is used to inspire and to highlight the potential for change and growth. It is a rhetorical tool that adds weight and dignity to the speech. Reading classic Portuguese authors like Machado de Assis or Eça de Queirós, you will find 'vigor' used to describe the character of individuals or the intensity of their passions, reflecting the 19th-century focus on temperament and constitution.

In the business world, 'vigor' is used to describe a company's health or the state of the market. A 'mercado com vigor' is one that is growing and active. Managers might discuss the 'vigor da marca' (brand vigor), referring to how strong and recognizable the brand is in the eyes of consumers. This usage is particularly common in financial reports and strategic planning meetings. It conveys a sense of momentum and sustainability. If a business is losing its 'vigor', it is a sign that it needs innovation or a change in direction.

Apesar da crise, o setor de tecnologia continua operando com pleno vigor no país.

Daily Life Examples: - Hearing a grandmother say her plants have 'vigor' because of the new fertilizer.
- Reading a contract that states 'Este contrato entra em vigor na data de sua assinatura'.
- Watching a historical documentary about the 'vigor' of an ancient empire.

Lastly, you might hear 'vigor' in religious or philosophical discussions. It can represent the strength of one's faith or the 'vigor da alma' (vigor of the soul). In these deep, contemplative settings, the word moves away from the physical and the legal toward the spiritual. It suggests an inner strength that remains even when the body fails. This versatility—from the courtroom to the gym to the church—is what makes 'vigor' such a fascinating and essential word in the Portuguese vocabulary. Pay attention to the tone of the speaker; 'vigor' is almost always a word of significance.

One of the most common mistakes English speakers make when using 'vigor' in Portuguese is assuming it is an exact 1:1 replacement for 'energy' (energia) in all contexts. While they are related, 'energia' is much broader and more informal. You can have 'energia' to go to a party, but having 'vigor' implies a deeper, more robust physical or institutional capacity. If you say 'Eu não tenho vigor para limpar a casa', it sounds a bit overly dramatic, as if you are suffering from a serious lack of constitution. In that case, 'energia' or 'força' would be more natural. Use 'vigor' when you want to emphasize a sustained, healthy, or official strength.

Mistake: Confusing 'Vigor' with 'Vigência': While 'em vigor' means 'in force', the noun for the period of time something is in force is 'vigência'. Many learners say 'o vigor da lei' when they mean 'a vigência da lei' (the period the law is active). 'Vigor' is the state; 'vigência' is the duration.
Mistake: Incorrect Preposition: Learners often try to translate 'in force' literally as 'em força'. This is incorrect. The fixed legal expression is always 'em vigor'. Saying 'A lei está em força' will sound strange to a native speaker.

Another frequent error involves the verb 'vigiar' (to watch/guard). Because 'vigor' and 'vigiar' start with the same four letters, some students confuse them. 'Vigiar' is about surveillance, while 'vigor' is about vitality. There is also the word 'vigário' (vicar), which has absolutely nothing to do with strength or laws. Be careful not to mix these up in your mind. Additionally, some learners forget that 'vigor' is a masculine noun. They might say 'a vigor' because they are thinking of other abstract nouns that end in 'or' (though most 'or' words are masculine, some learners get confused by 'a dor' or 'a cor'). Always remember: O vigor.

Erro Comum: 'A nova lei entra em força amanhã.'
Correto: 'A nova lei entra em vigor amanhã.'

In terms of pronunciation, English speakers sometimes over-emphasize the 'r' at the end, making it sound too much like the English 'r'. In Portuguese, especially in Brazil, the final 'r' can be a soft 'h' sound (as in 'house') or a tapped 'r' (like the 'tt' in 'better'), depending on the region. In Portugal, it is usually a distinct, alveolar tap. Getting this 'r' right is key to sounding natural. Also, ensure the 'o' is closed (/o/), not open (/ɔ/). It should sound like the 'o' in 'go', but without the 'u' sound at the end.

Finally, watch out for the adjective 'vigoroso'. While it is the direct adjective form of 'vigor', it is often used for things like 'um aperto de mão vigoroso' (a firm/vigorous handshake). If you use 'vigor' as a noun to describe a handshake ('um aperto de mão com vigor'), it is also correct, but 'vigoroso' is more common for physical attributes. Conversely, for laws, you almost never use the adjective; you stick to the phrase 'em vigor'. Understanding these subtle preferences in usage will help you avoid sounding like a translation machine and more like a fluent speaker.

Confusão: 'Ele tem muita vigência física.'
Correto: 'Ele tem muito vigor físico.'

Summary of Mistakes: - Using 'energia' when 'vigor' (physical robustness) is required.
- Saying 'em força' instead of 'em vigor' for laws.
- Confusing 'vigor' (state) with 'vigência' (duration).
- Misgendering the word (it is always masculine).

By paying attention to these nuances, you will be able to use 'vigor' with the same confidence and precision as a native speaker. It is a word that rewards careful usage, as it carries a certain level of sophistication and clarity that simpler words lack. Keep practicing with the phrase 'entrar em vigor' and describing physical activities 'com vigor', and soon it will feel like a natural part of your vocabulary.

To truly master 'vigor', you need to know its neighbors. Portuguese has several words that touch on the concepts of strength, energy, and validity. Knowing which one to pick depends on the context and the 'flavor' you want to give your sentence. The most common alternative is energia. While 'vigor' implies a robust, healthy constitution, 'energia' is the general fuel for action. You can have 'energia' but still lack 'vigor' if you are feeling thin or weak. Think of 'energia' as the gasoline and 'vigor' as the high-performance engine.

Vigor vs. Energia: 'Vigor' is more formal and specific to physical health or legal status. 'Energia' is used for everything from electricity to a person's mood. You would say 'a bateria está sem energia', but never 'a bateria está sem vigor'.
Vigor vs. Vitalidade: 'Vitalidade' is very close to 'vigor'. However, 'vitalidade' often has a more positive, life-affirming connotation. It is about the spark of life. 'Vigor' feels a bit more structured and powerful. You might describe a child's play as having 'vitalidade', but an athlete's performance as having 'vigor'.
Vigor vs. Validade: In legal contexts, 'vigor' is about the law being active ('em vigor'). 'Validade' is about whether the law is legally sound or if a product is still good to eat ('data de validade'). A law can be 'em vigor' but its 'validade' could be challenged in court.

Another word to consider is robustez. This specifically refers to physical sturdiness. If you are talking about a building or a person with a very large, strong frame, 'robustez' is a great choice. 'Vigor' is more about the energy inside that frame. A small person can have incredible 'vigor', but they might lack 'robustez'. In the digital world, software is often described as having 'robustez' if it doesn't crash easily, whereas you wouldn't typically use 'vigor' for software unless you were speaking very metaphorically about its market presence.

Comparação:
1. 'A lei ainda tem validade.' (The law is still legally sound.)
2. 'A lei ainda está em vigor.' (The law is still being enforced.)

For the 'intensity' aspect of 'vigor', you might use intensidade or ímpeto. 'Ímpeto' suggests a sudden burst of energy or a drive to do something. 'Vigor' is more sustained. If someone starts a project with 'ímpeto', they are very excited at the beginning. If they work with 'vigor', they are maintaining a strong, steady effort throughout. 'Intensidade' is a neutral measure of how much force is being applied, whereas 'vigor' almost always carries a connotation of health and positive strength.

Finally, let's look at pujança. This is a higher-level vocabulary word that means great power, strength, or prosperity. It is often used in economic or agricultural contexts. 'A pujança da colheita' (the strength/abundance of the harvest) or 'a pujança econômica do país'. 'Vigor' is a bit more common and versatile, but 'pujança' is what you would use if you wanted to sound very literary or impressed by the scale of someone's strength or wealth.

O idoso caminhava com uma vitalidade invejável, mas era seu vigor mental que mais impressionava a todos.

Quick Reference Table: - Use Vigor for: Laws, physical stamina, sustained intensity.
- Use Energia for: Electricity, general activity, mood.
- Use Vitalidade for: Spark of life, youthful spirit.
- Use Robustez for: Sturdiness, physical frame, software stability.

Understanding these distinctions allows you to paint a more detailed picture in Portuguese. Instead of just saying things are 'strong' (forte), you can specify if they are legally active, physically robust, or spiritually alive. This level of nuance is what separates a student from a truly proficient speaker.

Tips

Upgrade your 'força'

If you are writing an essay and find yourself using 'força' too much, try replacing it with 'vigor' to describe human effort or institutional power. It sounds more sophisticated.

Check the date

In Portuguese contracts, always look for the clause 'entra em vigor na data de sua assinatura'. This tells you exactly when the agreement starts.

Vigor vs. Energia

Think of 'energia' as something temporary (like after a coffee) and 'vigor' as something permanent (like being a healthy, strong person).

Masculine noun

Even though many abstract qualities in other languages are feminine, 'vigor' is masculine. Use 'o' and '-o' endings for adjectives.

The final R

In Portugal, tap the 'r' with your tongue. In Brazil, you can often just make a soft 'h' sound at the back of your throat.

Natural forces

You can use 'vigor' to describe a storm or a river's current. It conveys a sense of unstoppable natural power.

Collocations

Memorize 'entrar em vigor' as a single unit. Don't try to translate 'come into force' word-for-word.

Character study

When reading Portuguese novels, 'vigor' is often used to show a character's strong will or determination.

Gardening

Use 'vigor' to describe how well your plants are growing. It's a common way to talk about healthy vegetation.

Challenge

Try to use 'vigor' in two different ways today: once to describe a healthy person or plant, and once to talk about a rule or law (like 'the rules of this game are in vigor').

Word Origin

The word 'vigor' comes directly from the Latin 'vigor, vigoris'. It is derived from the verb 'vigere', which means 'to be lively, to thrive, or to flourish'.

Original meaning: In Latin, it referred to life, activity, and force, both in physical and metaphorical senses.

It is a Romance language word, sharing cognates with the Italian 'vigore', Spanish 'vigor', and French 'vigueur'.

Cultural Context

There are no major sensitivities, but be careful not to use 'vigor' to describe someone's health in a way that sounds clinical if you are in a very casual setting.

English speakers often use 'vigour' (UK) or 'vigor' (US) less frequently than Portuguese speakers use 'vigor'. In English, 'energy' or 'stamina' is more common for physical health, and 'in force' is used for laws.

The phrase 'em pleno vigor das faculdades mentais' is a staple in Brazilian legal thrillers and historical biographies. The character 'Gil do Vigor' from the Brazilian reality show Big Brother Brasil 21 became a national icon, using the word to represent his intense and joyful personality. Classical Portuguese literature often uses 'vigor' to describe the 'temperamento' (temperament) of its protagonists.
