Explanation indispensável in your Level:
At the A1 beginner level, the word 'indispensável' might seem a bit long and intimidating, but it is incredibly useful to learn early on. At this stage, learners are primarily focused on basic survival vocabulary, expressing simple needs, and identifying everyday objects. While a beginner might rely heavily on simpler words like 'muito importante' (very important) or 'preciso de' (I need), introducing 'indispensável' helps them understand signs, basic instructions, and simple texts. For an A1 learner, the concept is taught through highly visual and concrete examples. For instance, a teacher might show a picture of a car and a key, explaining that the key is 'indispensável' to start the car. Or, they might show a picture of a person drinking water, noting that water is 'indispensável'. The focus is not on complex grammar, but on recognizing the word as a strong synonym for 'necessary'. A1 learners should practice pronouncing the word slowly, breaking it down into syllables: in-dis-pen-sá-vel, paying special attention to the stress on the 'sá'. They should also learn the basic phrase 'é indispensável' (it is indispensable) to express strong necessity in a simple, direct way. By recognizing this word, beginners can better navigate environments like airports or hospitals where critical instructions are given.

As learners progress to the A2 elementary level, their ability to construct sentences and express routines improves significantly. At this stage, 'indispensável' becomes an active part of their vocabulary for describing daily life, work requirements, and travel preparations. An A2 learner understands that 'indispensável' is an adjective and begins to practice its basic agreement, particularly the plural form 'indispensáveis'. They move beyond simple identification and start using the word in short, descriptive sentences. For example, when talking about their job, an A2 learner might say, 'O computador é indispensável para o meu trabalho' (The computer is indispensable for my work). When discussing travel, they can create packing lists, identifying items like passports and tickets as 'documentos indispensáveis'. The focus at the A2 level is on pairing the word with the correct preposition, primarily 'para' (for). Teachers encourage A2 students to replace the overused phrase 'muito importante' with 'indispensável' to elevate their spoken and written Portuguese. They also begin to encounter the word in short reading passages, such as simple blog posts about health (e.g., 'Dormir é indispensável') or basic job advertisements. Mastery at this level involves confident pronunciation and correct singular/plural usage in everyday contexts.

At the B1 intermediate level, learners are expected to handle a wider range of topics, express opinions, and deal with most situations likely to arise while traveling. 'Indispensável' is firmly established as a core vocabulary word at this stage. B1 learners use it to articulate arguments, give advice, and discuss abstract concepts rather than just physical objects. They understand the nuanced difference between 'importante', 'necessário', and 'indispensável', choosing the latter for emphasis and impact. A critical grammatical leap at the B1 level is the introduction of the subjunctive mood. Learners are taught the impersonal expression 'É indispensável que...' (It is indispensable that...) and must practice following it with the present subjunctive. For example: 'É indispensável que você estude mais' (It is indispensable that you study more). This structure is heavily practiced in writing assignments, such as formal emails, opinion essays, or letters of complaint. Furthermore, B1 learners encounter 'indispensável' in authentic listening materials, such as news broadcasts, podcasts, and interviews, where native speakers use it to discuss societal issues, economics, or politics. The goal at B1 is to use the word fluidly, accurately applying both prepositional collocations ('para') and subjunctive triggers ('que').
Reaching the B2 upper-intermediate level means the learner can interact with a degree of fluency and spontaneity that makes regular interaction with native speakers quite possible without strain. At this level, the use of 'indispensável' becomes highly sophisticated and natural. B2 learners do not just use the word; they play with its placement in the sentence for rhetorical effect and use it in complex, multi-clause sentences. They are comfortable using it in professional and academic environments, writing detailed reports, cover letters, or academic essays where precise vocabulary is demanded. For instance, a B2 learner might write, 'A implementação de novas tecnologias provou-se indispensável para a otimização dos recursos da empresa' (The implementation of new technologies proved indispensable for the optimization of the company's resources). They also fully grasp the morphological breakdown of the word (in + dispensar + ável) and can use this knowledge to understand or guess the meaning of related words (like 'dispensável' - expendable). At B2, learners are also expected to recognize and use synonyms like 'imprescindível', 'vital', and 'fundamental' interchangeably to avoid repetition and demonstrate lexical variety. The focus is on register, ensuring the word is used appropriately in both formal and informal, yet serious, contexts.

At the C1 advanced level, learners possess a vast vocabulary and can express ideas fluently and spontaneously without much obvious searching for expressions. The word 'indispensável' is used with native-like precision. C1 learners understand the subtle cultural and contextual weights of the word. They use it effortlessly in high-level debates, negotiations, and complex academic writing. At this stage, the focus is on collocations, idiomatic usage, and stylistic elegance. A C1 learner might use phrases like 'condição indispensável' (prerequisite/indispensable condition) or 'fator indispensável' (indispensable factor) in formal discourse. They are also adept at using the word in literary or abstract contexts, perhaps discussing philosophical concepts where certain virtues are deemed 'indispensáveis' for a just society. Furthermore, C1 learners can easily navigate complex grammatical structures involving the word, such as passive voices or conditional sentences: 'Teria sido indispensável que ele chegasse mais cedo' (It would have been indispensable for him to arrive earlier). They are highly sensitive to tone and can use 'indispensável' ironically or hyperbolically if the situation calls for it. Mastery at C1 means the word is fully integrated into the learner's linguistic repertoire, deployed automatically and flawlessly.

At the C2 proficiency level, the learner's command of Portuguese is virtually indistinguishable from that of a highly educated native speaker. They can understand with ease virtually everything heard or read. For a C2 learner, 'indispensável' is merely one tool in an expansive and highly refined linguistic arsenal. They understand the historical etymology of the word and how its usage has evolved. In writing, a C2 user employs 'indispensável' to craft compelling, persuasive, and rhetorically flawless arguments in legal documents, scientific papers, or literary critiques. They are capable of recognizing and utilizing the most obscure and formal synonyms, such as 'imprescindível' or 'sine qua non' (used as a borrowed phrase in Portuguese). A C2 learner can also play with the word's morphology creatively, perhaps coining new phrases or using it in highly poetic ways. They perfectly understand the socio-linguistic implications of using such a strong word in delicate social situations, knowing exactly when it is appropriate to assert absolute necessity and when a softer approach is required. At this ultimate level of proficiency, 'indispensável' is used not just to communicate a need, but to shape thought, influence opinions, and demonstrate absolute mastery over the nuances of the Portuguese language.

indispensável in 30 Seconds

  • Means 'absolutely necessary' or 'essential'.
  • Stronger than 'importante' (important).
  • Plural form is 'indispensáveis'.
  • Usually followed by the preposition 'para'.
The Portuguese adjective 'indispensável' is a highly versatile, frequently used, and structurally profound word that translates directly to 'indispensable', 'essential', or 'absolutely necessary' in the English language. When we delve into the core meaning of this particular vocabulary item, we are fundamentally discussing something that simply cannot be set aside, ignored, bypassed, or done without under any reasonable circumstances. It implies a level of absolute, undeniable necessity that goes far beyond mere importance or preference. For instance, while having a comfortable pair of shoes might be considered important for a long journey, having a valid passport is absolutely indispensável if you are traveling internationally. This critical distinction between 'important' and 'indispensable' is crucial for language learners to grasp early on to elevate their expressive accuracy. Let us break down the morphological structure of the word to better understand its origins, its linguistic DNA, and how it functions within the broader context of the Portuguese language. The word is meticulously formed by three distinct morphological components: the prefix 'in-', the root verb 'dispensar', and the suffix '-ável'.
Prefix: in-
This prefix denotes negation, absence, or the opposite of the root word, similar to 'un-' or 'in-' in English.
Root: dispensar
This verb means to dismiss, to excuse, to give up, or to do without something or someone.
Suffix: -ável
This suffix indicates capability, possibility, or suitability, equivalent to '-able' in English.
Therefore, when you combine these three distinct linguistic elements, 'in-dispens-ável' literally and beautifully translates to 'not capable of being done without'. This morphological breakdown is an excellent, highly effective way for learners to memorize the word and deeply understand its fundamental essence.

A água é um recurso indispensável para a sobrevivência de todos os seres vivos no planeta Terra.

Furthermore, understanding this word opens the door to a broader comprehension of Portuguese adjectives ending in '-ável', which are incredibly common and follow similar stress and pluralization rules. When pluralized, 'indispensável' becomes 'indispensáveis', following the standard rule of replacing the final 'l' with 'is' for words ending in '-el'.

Os documentos são indispensáveis para a conclusão do processo de matrícula na universidade.

In everyday conversation, you will hear native speakers use this word to emphasize the critical nature of an object, a person's role, or a specific action. It elevates the register of the conversation slightly, making it sound more formal and precise than simply saying 'muito necessário'.

O seu apoio foi indispensável para o sucesso do nosso projeto de caridade no mês passado.

Para fazer um bom bolo, a farinha de trigo é um ingrediente absolutamente indispensável.

A presença do diretor é indispensável na reunião de amanhã para tomarmos a decisão final.

By mastering the nuances, the morphological roots, and the precise contexts in which 'indispensável' thrives, learners can significantly enrich their vocabulary, express themselves with greater authority, and sound much more like fluent, educated native speakers of Portuguese.
Understanding how to correctly use the adjective 'indispensável' in various grammatical and syntactic contexts is a fundamental step for any Portuguese learner aiming for fluency and precision. This word, while straightforward in its meaning, requires careful attention to its placement within a sentence, its agreement with the nouns it modifies, and the specific prepositions it frequently pairs with. First and foremost, as an adjective, 'indispensável' must always agree in number with the noun it describes. Because it ends in '-l', it is a uniform adjective regarding gender; meaning, it does not change form whether it is describing a masculine or a feminine noun.
Gender Neutrality
You say 'o livro indispensável' (masculine) and 'a ferramenta indispensável' (feminine). The adjective remains exactly the same.
However, it does change for the plural. The rule for adjectives ending in '-el' is to drop the 'l' and add 'is'. Therefore, the plural form is 'indispensáveis'.
Pluralization Rule
Change 'o recurso indispensável' to 'os recursos indispensáveis'. The accent mark remains on the 'á' to maintain the paroxytone stress.

Estas ferramentas são indispensáveis para consertar o motor do carro antigo.

Regarding syntax and sentence structure, 'indispensável' is most commonly placed immediately after the noun it modifies, which is the standard position for descriptive adjectives in Portuguese. However, it can also function as a predicative adjective, following a linking verb such as 'ser' (to be), 'tornar-se' (to become), or 'considerar' (to consider).

A paciência tornou-se indispensável durante os longos meses de negociação do contrato.

One of the most critical aspects of using 'indispensável' correctly is mastering its collocations, particularly the prepositions that follow it. When you want to state what something is indispensable *for*, you must use the preposition 'para' (for/to). This is a highly frequent pattern: [Noun] + ser + indispensável + para + [Noun/Infinitive Verb].
Preposition Pairing
Always use 'para' when indicating the purpose or the beneficiary of the indispensable item or action.

O estudo diário é indispensável para aprender um novo idioma com fluência e confiança.

Another common structure involves using 'indispensável' in impersonal expressions. For example, 'É indispensável que...' (It is indispensable that...). When you use this structure, it triggers the subjunctive mood in the following dependent clause, because it expresses a necessity, a demand, or a strong recommendation.

É indispensável que você chegue ao aeroporto com pelo menos três horas de antecedência.

Finally, 'indispensável' can occasionally be used as a noun itself, preceded by a definite article, to refer to 'the essential things' or 'the bare necessities'. For instance, 'Ele viajou apenas com o indispensável' (He traveled with only the bare essentials).

Na hora de arrumar a mala para o acampamento, leve estritamente o indispensável.

By paying close attention to these grammatical rules, pluralization patterns, prepositional pairings, and subjunctive triggers, learners can confidently integrate 'indispensável' into their daily Portuguese communication.
The adjective 'indispensável' is omnipresent in the Portuguese language, permeating various spheres of daily life, professional environments, academic discourse, and media. Because it conveys a strong sense of absolute necessity, it is a word that naturally arises in situations where priorities are being established, rules are being enforced, or critical advice is being given. One of the most common environments where you will hear 'indispensável' is in the workplace and corporate settings. In job descriptions, performance reviews, and project planning meetings, this word is used to highlight crucial skills, mandatory requirements, or key personnel.

O domínio da língua inglesa é um requisito indispensável para esta vaga de gerente de marketing internacional.

Corporate Context
Used heavily in HR documents, job postings, and strategic planning to define non-negotiable elements of a role or project.
Another frequent context is within the realms of health, wellness, and medical advice. Doctors, nutritionists, and fitness instructors frequently use 'indispensável' to emphasize the importance of certain habits, nutrients, or medical procedures. When a doctor tells you that a medication is indispensable, they are conveying that your recovery depends on it.

Uma alimentação balanceada e a prática de exercícios físicos são indispensáveis para manter uma boa saúde cardiovascular.

You will also encounter this word frequently in educational and academic settings. Teachers and professors use it to outline course requirements, essential reading materials, and mandatory attendance policies. It sets the baseline for what a student must do to succeed.
Academic Context
Look for this word in syllabi (planos de ensino) to identify the books and materials you absolutely must purchase or read.

A leitura deste artigo científico é indispensável para a compreensão do próximo capítulo do nosso curso de biologia.

Furthermore, 'indispensável' is a staple in the worlds of travel, tourism, and event planning. When preparing for a trip, guidebooks and travel blogs will list the 'itens indispensáveis' (indispensable items) you need to pack. Similarly, event organizers will talk about the indispensable elements needed to make a conference or a wedding successful.

O protetor solar e um bom chapéu são itens indispensáveis para quem vai passar as férias nas praias do Nordeste brasileiro.

Finally, in everyday interpersonal relationships and emotional contexts, people use 'indispensável' to express deep appreciation and reliance on someone else. Telling a friend, a partner, or a colleague that they are indispensable is a profound compliment, indicating that their presence or help is vital to your happiness or success.
Emotional Context
Used to express deep gratitude and the irreplaceable nature of a person in someone's life.

Quero agradecer a todos pela ajuda, mas o apoio da minha família foi verdadeiramente indispensável nesta jornada difícil.

By recognizing these diverse contexts—from the rigid requirements of a job posting to the heartfelt gratitude expressed to a loved one—learners can appreciate the dynamic range of 'indispensável' and begin to incorporate it naturally into their own varied conversations.
While 'indispensável' is a highly useful word, language learners frequently stumble over a few common pitfalls regarding its spelling, pronunciation, grammatical agreement, and nuanced usage. Addressing these mistakes early on is crucial for developing accurate and confident Portuguese. The most prevalent mistake, by far, involves the spelling and the accent mark. Many learners, especially those whose native languages do not use diacritics, forget to include the acute accent (acento agudo) on the 'a': writing 'indispensavel' instead of the correct 'indispensável'.
Spelling Error
Forgetting the accent mark changes the theoretical stress of the word and is considered a significant orthographic error in formal writing.

Incorrect: A água é indispensavel.
Correct: A água é indispensável.

Another frequent error occurs during pluralization. Because the singular form ends in 'l', learners sometimes incorrectly add an 's' to the end, creating the non-existent word 'indispensávels'. The correct rule for adjectives ending in '-el' is to drop the 'l' and add '-is', resulting in 'indispensáveis'.
Pluralization Error
Applying the standard English pluralization rule (just adding 's') to a Portuguese word ending in 'l' will always result in an error.

Incorrect: Estes documentos são indispensávels.
Correct: Estes documentos são indispensáveis.

Grammatically, learners often struggle with the preposition that follows 'indispensável'. Influenced by English ('indispensable to'), learners might say 'indispensável a'. While not entirely grammatically incorrect in highly formal or poetic contexts, it sounds unnatural in everyday Portuguese. The overwhelmingly preferred and correct preposition is 'para'.

Incorrect (Unnatural): O oxigênio é indispensável à vida.
Correct (Natural): O oxigênio é indispensável para a vida.

Furthermore, learners sometimes use 'indispensável' when a weaker adjective like 'importante' (important) or 'útil' (useful) would be more appropriate. Overusing 'indispensável' dilutes its strong meaning. If something is merely helpful but you could survive or succeed without it, it is not indispensable.
Semantic Overuse
Using 'indispensável' for trivial things makes the speaker sound overly dramatic or imprecise.

Overdramatic: Um café extra é indispensável hoje. (Unless you literally cannot function, 'necessário' or 'importante' is better).
Accurate: O cinto de segurança é indispensável para a sua proteção.

Finally, a common syntactic mistake involves the impersonal expression 'É indispensável que...'. Learners often forget that this structure absolutely requires the verb in the following clause to be conjugated in the subjunctive mood, not the indicative.

Incorrect: É indispensável que você estuda (indicative) todos os dias.
Correct: É indispensável que você estude (subjunctive) todos os dias.

By consciously avoiding these spelling, pluralization, prepositional, semantic, and subjunctive errors, learners will master the use of 'indispensável' and significantly improve the overall grammatical accuracy of their Portuguese.
To truly master a language, one must not only understand a word in isolation but also comprehend its relationship to other words within the same semantic field. The Portuguese language offers a rich tapestry of synonyms and related terms for 'indispensável', each carrying its own subtle nuances, specific contexts of use, and varying degrees of intensity. Exploring these similar words allows learners to express themselves with greater precision, avoid repetitive vocabulary, and understand native speakers more deeply. The most direct and commonly used synonym is 'essencial' (essential). In most contexts, 'essencial' and 'indispensável' can be used interchangeably without any loss of meaning. Both convey that something is absolutely necessary.
Essencial
The closest synonym. It relates to the 'essence' of something, meaning without it, the thing cannot exist or function properly.

A confiança é essencial (ou indispensável) para qualquer relacionamento duradouro.

Another powerful synonym is 'fundamental' (fundamental). This word shares the idea of absolute necessity but carries a slightly different metaphorical weight. It suggests that the item or concept in question serves as the foundation or the base upon which everything else is built.
Fundamental
Best used when describing core principles, basic rules, or foundational elements of a system or theory.

O respeito mútuo é fundamental para manter a paz no ambiente de trabalho.

For situations involving life, death, or extreme urgency, the word 'vital' (vital) is highly appropriate. Derived from the Latin word for life ('vita'), 'vital' literally means necessary for life. While it can be used metaphorically, it always carries a sense of extreme urgency and high stakes.

A chegada rápida da ambulância foi vital para salvar a vida do paciente acidentado.

Moving slightly down the scale of intensity, we find words like 'necessário' (necessary) and 'importante' (important). It is crucial to understand that while these are related, they are weaker than 'indispensável'. Something can be necessary but not strictly indispensable (perhaps there is a difficult workaround). Something can be important, but its absence won't cause total failure.
Necessário vs. Indispensável
'Necessário' means you need it. 'Indispensável' means you absolutely cannot do without it under any circumstances.

É necessário estudar, mas a dedicação total é indispensável para passar no exame de medicina.

Finally, in legal, administrative, or highly regulated contexts, you might encounter the word 'obrigatório' (mandatory/obligatory). While 'indispensável' focuses on practical necessity (you need it to succeed), 'obrigatório' focuses on imposed rules (you need it because a rule or law says so).

O uso de capacete é obrigatório por lei, e também indispensável para a sua segurança na moto.

By understanding the subtle differences between essencial, fundamental, vital, necessário, and obrigatório, learners can choose the exact right word for every situation, demonstrating a sophisticated command of Portuguese vocabulary.

How to Use It

nuance

Carries a heavier weight of absolute necessity compared to 'necessário'. Do not use it for trivial preferences.

formality

Appropriate for all registers, but leans slightly formal. It is never out of place in professional or academic settings.

Common Mistakes
  • Writing 'indispensavel' without the acute accent on the 'a'.
  • Pluralizing it as 'indispensávels' instead of the correct 'indispensáveis'.
  • Using the preposition 'a' (indispensável a) instead of the much more natural 'para' (indispensável para).
  • Following 'É indispensável que...' with a verb in the indicative mood instead of the required subjunctive mood.
  • Using 'indispensável' to describe things that are merely 'nice to have' or 'somewhat important', thereby diluting its strong meaning.

Always remember that the phrase 'É indispensável que...' is a classic trigger for the present subjunctive. Do not use the indicative. Practice this by writing five sentences starting with this phrase and conjugating the following verb in the subjunctive.

Don't Forget the Accent

The acute accent on the 'á' is not optional. It is required to show that the stress falls on the penultimate syllable. Make it a habit to physically write the accent mark immediately when you write the letter 'a' in this word.

Upgrade Your Vocabulary

Challenge yourself to stop using 'muito importante' for one week. Every time you want to say something is very important, force yourself to evaluate if it is 'indispensável'. If it is, use the new word to build your active vocabulary.

Stress the 'SÁ'

When speaking, ensure the loudest and longest syllable is 'sá'. Practice saying it slowly: in-dis-pen-SÁ-vel. Correct stress makes you sound much more natural and easily understood by native speakers.

Pair with 'Para'

Memorize 'indispensável' and 'para' as a single chunk of language. When you learn them together ('indispensável para'), you won't have to pause and think about which preposition to use during a fast-paced conversation.

The '-el' to '-eis' Rule

Use 'indispensável' to anchor the pluralization rule for all adjectives ending in '-el'. If you know 'indispensável' becomes 'indispensáveis', you also know 'amável' becomes 'amáveis' and 'incrível' becomes 'incríveis'.

Professional Resumes

If you are writing a resume or cover letter in Portuguese, use 'indispensável' to describe the skills you possess that match the job description. It shows confidence and a strong command of professional language.

Scan Bureaucratic Texts

When dealing with visas, university enrollments, or government forms in a Portuguese-speaking country, scan the document for the word 'indispensável'. Whatever follows that word is something you absolutely must provide to avoid rejection.

Avoid Redundancy

Try to avoid saying 'muito indispensável'. Because the word already implies a maximum level of necessity, adding 'muito' is redundant. Use 'absolutamente indispensável' if you really need to add dramatic flair.

Learn the Latin Equivalent

In highly formal, legal, or academic texts, you might see the Latin phrase 'condição sine qua non'. This means exactly the same thing as 'condição indispensável'. Recognizing this will boost your advanced reading comprehension.

Memorize It

Mnemonic

IN (not) + DISPENS (dispense/throw away) + ABLE (able). You are NOT ABLE to THROW it AWAY because you need it.

Visual Association

Imagine a survival kit. Everything inside it is 'indispensável'. If you take anything out, you might not survive.

Word Origin

From Medieval Latin 'indispensabilis'.

Cultural Context

Commonly used in job requirements and bureaucratic lists (e.g., Detran, Polícia Federal).

Used similarly, often in academic and formal administrative contexts (e.g., Finanças, SEF).

In very informal settings, people might hyperbolically call a specific brand of beer or a soccer player 'indispensável' for a good weekend.

No, it does not. 'Indispensável' is a uniform adjective regarding gender. This means you use the exact same word for masculine nouns (o livro indispensável) and feminine nouns (a ferramenta indispensável). You only need to worry about changing it for the plural.

To make it plural, you drop the final 'l' and add 'is'. So, 'indispensável' becomes 'indispensáveis'. Remember to keep the accent mark on the 'á' in the plural form as well. For example: 'os documentos indispensáveis'.

The most common and natural preposition to use is 'para' (for). You use it to indicate what the item is indispensable for. For example: 'A água é indispensável para a vida' (Water is indispensable for life). Avoid using 'a' unless you are writing highly formal literature.

In Portuguese, impersonal expressions that convey necessity, doubt, emotion, or desire trigger the subjunctive mood in the following clause. Because 'É indispensável que' expresses an absolute necessity or demand, the verb that follows must be in the subjunctive to reflect that required state. Example: 'É indispensável que você vá' (It is indispensable that you go).

Yes, you can use it as a noun by placing the definite article 'o' in front of it: 'o indispensável'. In this context, it translates to 'the bare essentials' or 'only what is strictly necessary'. For example: 'Na viagem, levei apenas o indispensável'.

'Importante' means something has value or significance, but you might still succeed or survive without it. 'Indispensável' is much stronger; it means absolute necessity. If something is indispensable, you cannot function, succeed, or survive without it. Use 'indispensável' for strict requirements.

It is a standard word that is appropriate in all contexts, but it does elevate the register slightly compared to just saying 'preciso muito' (I need it a lot). It is highly common in formal writing, business, academia, and bureaucracy, but also perfectly normal in everyday conversation.

If you write 'indispensavel' without the accent, it is a spelling error. In Portuguese, the accent mark dictates the stress of the word. Without it, the rules of pronunciation would technically shift the stress to the last syllable (vel), which is incorrect. Always write 'indispensável'.

The most direct and common synonym is 'essencial'. Another excellent synonym is 'fundamental'. If you are writing a very formal text, you can use 'imprescindível'. All of these convey the idea of absolute necessity.

While you might hear it in casual speech, it is technically redundant. 'Indispensável' already means 'absolutely necessary', so adding 'muito' (very) is like saying 'very absolutely necessary'. It is better to use adverbs like 'absolutamente' (absolutely) or 'estritamente' (strictly) for emphasis: 'absolutamente indispensável'.
