At the A1 level, the verb 'opinar' might be a bit advanced, as beginners usually focus on simpler verbs like 'achar' (to think/to find). However, it is useful to recognize it as a word that means 'to give an opinion.' At this stage, you should know that it is a regular verb ending in '-ar,' so it follows the same pattern as 'falar' (to speak) or 'gostar' (to like). You might see it in simple contexts like 'Eu opino' (I give an opinion) or 'Ele não opina' (He doesn't give an opinion). Think of it as a formal way to say what you think. While you might not use it every day, knowing that it exists will help you understand when others are talking about their views. It is a good word to add to your vocabulary once you are comfortable with basic verbs. Focus on the present tense: 'eu opino,' 'você opina,' 'nós opinamos,' 'eles opinam.' This will give you a solid foundation for using it in simple sentences about your preferences or simple choices.
At the A2 level, you can start using 'opinar' in more structured sentences. You should learn that it is often followed by the preposition 'sobre' (about). For example, 'Eu quero opinar sobre o livro' (I want to give an opinion about the book). This level is about building connections between words, and 'opinar sobre' is a very common and useful connection. You might also encounter it in the past tense (Pretérito Perfeito) to talk about something you already said: 'Eu opinei sobre o filme ontem' (I gave my opinion about the movie yesterday). At A2, you are also learning to express your needs and desires, so phrases like 'Posso opinar?' (May I give an opinion?) are very useful in social situations. You are moving beyond just 'achar' and starting to use 'opinar' to sound a bit more deliberate and clear in your communication. It’s a great way to participate in small group discussions or to give feedback on simple tasks.
At the B1 level, you are expected to handle 'opinar' with more confidence in a variety of situations. This is the level where you start to engage in more complex discussions and express your views on current events or personal experiences. You should be comfortable using 'opinar' with 'que' to introduce a clause: 'O meu amigo opinou que a viagem foi muito cara' (My friend expressed the opinion that the trip was very expensive). You will also notice 'opinar' in media reports or more formal conversations. At this stage, you should be aware of the difference between 'opinar' and 'achar'—using 'opinar' when you want to sound more professional or when you are providing a formal judgment. You can also start using it in the future tense and the imperfect: 'Eu opinava sempre nas reuniões' (I used to always give my opinion in meetings). This shows a higher level of grammatical control and allows you to describe habits and future intentions related to expressing your thoughts.
At the B2 level, 'opinar' becomes a tool for nuanced debate and professional communication. You should be able to use it in the subjunctive mood to express hypothetical situations or polite requests: 'Eu gostaria que você opinasse sobre este assunto' (I would like you to give your opinion on this matter). This level requires you to understand the social weight of 'opinar'—knowing when it is appropriate to give a formal opinion and when a more casual verb is better. you will also encounter the noun 'opinião' and its various collocations, such as 'formar uma opinião' (to form an opinion) or 'mudar de opinião' (to change one's mind), and understand how they relate back to the verb 'opinar.' You should be able to follow complex discussions in Portuguese where several people 'opinam' on a topic, and you should be able to contribute your own structured 'opinião' using the verb correctly in different tenses and moods.
At the C1 level, you should have a sophisticated grasp of 'opinar' and its synonyms. You will use it in academic, legal, or high-level professional contexts where precision is paramount. You should be able to distinguish 'opinar' from more formal alternatives like 'pronunciar-se' or 'manifestar-se' and choose the one that best fits the register of your conversation or writing. At this stage, you can use 'opinar' to analyze complex texts or to participate in philosophical debates. You will understand the subtle implications of the verb, such as when it is used to imply a certain level of authority or expertise. You should also be familiar with idiomatic expressions and more obscure uses of the verb in literature. Your use of 'opinar' should be seamless, integrated into a wide range of complex grammatical structures, including advanced subjunctive and conditional forms. You are not just using the word; you are using it to influence and shape the conversation.
At the C2 level, your mastery of 'opinar' is indistinguishable from that of a highly educated native speaker. You use the verb with total precision, capturing every nuance of meaning and tone. You can use it in highly specialized fields, such as law or philosophy, where the act of 'opinar' (issuing a 'parecer') has specific technical and legal consequences. You are also aware of the historical development of the word and its place within the broader family of Romance languages. You can use 'opinar' with a high degree of irony, humor, or rhetorical flourish. In writing, you use it to structure complex arguments, and in speaking, you use it to navigate the most delicate social and professional situations with grace and authority. At this level, 'opinar' is just one of many tools in your vast linguistic repertoire, used with effortless control and deep cultural understanding.

opinar en 30 secondes

  • Opinar is a regular Portuguese verb meaning to give an opinion or express a viewpoint.
  • It is more formal than 'achar' and is commonly used in media, professional, and social settings.
  • The verb is almost always followed by the preposition 'sobre' when specifying the topic being discussed.
  • It is essential for participating in debates and providing feedback in both casual and formal Portuguese contexts.

The Portuguese verb opinar is a fundamental pillar of communication, specifically within the realm of expressing one's thoughts, beliefs, or judgments. At its core, it translates to 'to give an opinion' or 'to express a viewpoint.' While it might seem straightforward, its usage spans a wide spectrum from formal academic debates to casual conversations among friends. In Portuguese culture, the act of 'opinar' is often seen as an essential part of social interaction, reflecting the value placed on dialogue and the exchange of ideas. Unlike the English word 'opine,' which can sometimes sound slightly archaic or overly formal, the Portuguese opinar is incredibly versatile and common in everyday speech.

Formal Contexts
In professional settings, such as board meetings or legal proceedings, 'opinar' is used when an expert or authority is asked to provide a formal assessment. For example, a lawyer might 'opinar' on the legality of a contract, or a doctor might 'opinar' on a specific course of treatment. This usage implies a level of responsibility and expertise behind the statement.
Casual Interactions
In a more relaxed setting, 'opinar' is frequently used when friends discuss movies, politics, or personal choices. It is the verbal act of contributing to a conversation by sharing what you think. It is often followed by the preposition 'sobre' (about), as in 'opinar sobre o novo filme' (to give an opinion about the new movie).

Eu não gosto de opinar sobre a vida alheia sem ser convidado.

Understanding the nuance of 'opinar' also involves recognizing its weight. To 'opinar' is more than just 'to say'; it is to take a stance. In Portuguese media, you will often see journalists or commentators being asked to 'opinar' on current events. This highlights the verb's role in the public sphere, where the exchange of opinions is vital for democracy. Furthermore, the verb is regular, ending in '-ar,' which makes it relatively easy for learners to conjugate across different tenses. However, the challenge lies in knowing when it is appropriate to use 'opinar' versus 'achar' (to think) or 'pensar' (to think/ponder). While 'achar' is very common for subjective feelings ('Eu acho que vai chover'), 'opinar' suggests a more deliberate act of expressing a thought process.

O especialista foi chamado para opinar sobre as mudanças climáticas.

Social Etiquette
In many Portuguese-speaking cultures, there is a fine line between being expressive and being 'opinativo' (opinionated). While 'opinar' is encouraged in debate, doing so excessively or without being asked can sometimes be perceived as intrusive, leading to the common phrase 'não dê pitaco,' which is a more colloquial way of saying 'don't give your unsolicited opinion.'

Você tem o direito de opinar, mas deve respeitar os outros.

To truly master 'opinar,' one must also look at its derivatives and related terms. The noun 'opinião' is the direct result of the act of 'opinar.' When you 'opinar,' you are generating an 'opinião.' In Portuguese, you might hear 'Na minha opinião...' (In my opinion...), but using the verb 'Eu opino que...' (I opine that...) is slightly more formal and assertive. This verb is also central to the concept of 'liberdade de expressão' (freedom of speech), as it represents the active exercise of that right. Whether you are a student writing an essay or a traveler chatting at a café in Lisbon or Rio de Janeiro, knowing how to use 'opinar' effectively will allow you to engage more deeply with the people and the culture.

Todos os cidadãos devem opinar sobre o futuro da cidade.

É difícil opinar quando não se conhece todos os fatos.

In summary, 'opinar' is a versatile verb that bridges the gap between personal thought and social expression. It is a tool for engagement, a marker of expertise, and a fundamental right in modern society. By learning its various contexts—from the formal to the casual—you gain a powerful way to express yourself and participate in the vibrant world of Portuguese communication.

Using the verb opinar correctly requires an understanding of its grammatical structure and the prepositions that typically accompany it. As a regular '-ar' verb, its conjugation follows the standard pattern, which is a relief for many learners. However, the nuance lies in its transitive or intransitive use and the specific contexts in which it appears. Most commonly, 'opinar' is used as a transitive indirect verb, meaning it requires a preposition—usually 'sobre' (about) or 'a respeito de' (regarding)—to connect it to the object of the opinion.

The 'Sobre' Pattern
This is the most frequent way to use 'opinar.' You use 'sobre' followed by a noun or a noun phrase. For example: 'Eles opinaram sobre o projeto' (They gave their opinion about the project). This structure is clear and direct, suitable for almost any context.

Eu gostaria de opinar sobre a nova política da empresa.

Another common structure is using 'opinar' with a 'que' clause. This is similar to saying 'to opine that...' in English. For instance: 'O diretor opinou que as vendas devem aumentar' (The director expressed the opinion that sales should increase). This is a more assertive way of speaking and is often found in formal reports or journalistic writing. It frames the opinion as a statement of belief or a professional assessment.

Intransitive Use
Sometimes, 'opinar' is used without a direct object or prepositional phrase when the context is already established. If someone asks, 'Você quer falar?' (Do you want to speak?), you might respond, 'Não, prefiro não opinar' (No, I prefer not to give an opinion). Here, the verb stands alone, emphasizing the act of expressing a view rather than the view itself.

Ela sempre opina de forma muito construtiva durante as aulas.

When using 'opinar' in the past tense, it often serves to recount a specific moment where a judgment was made. 'Ele opinou contra a decisão' (He gave an opinion against the decision). Notice the use of 'contra' (against) or 'a favor de' (in favor of) to show the direction of the opinion. This is particularly useful in political or legal discussions. In the future tense, 'opinar' can be used to indicate a forthcoming contribution: 'O comitê opinará na próxima semana' (The committee will give its opinion next week).

Negative Constructions
Negative sentences with 'opinar' often convey a sense of neutrality or a refusal to get involved. 'Eu não posso opinar sobre esse assunto' (I cannot give an opinion on this matter) is a polite and common way to decline comment, perhaps due to a lack of information or a conflict of interest.

Ninguém se atreveu a opinar diante do chefe irritado.

In more complex sentences, 'opinar' can be used in the subjunctive mood to express desire, doubt, or hypothetical situations. 'Se você opinasse mais, teríamos melhores resultados' (If you gave your opinion more, we would have better results). This shows the verb's flexibility in expressing not just facts, but also wishes and conditions. For learners, practicing 'opinar' in these different moods is key to reaching a B2 or C1 level of proficiency.

É importante que todos tenham a chance de opinar livremente.

Muitos internautas começaram a opinar nos comentários do vídeo.

Mastering the structures around 'opinar' allows you to participate in Portuguese-speaking society with confidence. Whether you are providing a professional critique or simply sharing your thoughts with a friend, understanding the prepositions and clauses that follow 'opinar' will make your speech sound natural and precise. Remember: 'opinar' is the bridge between your internal thoughts and the external world of conversation.

In the Portuguese-speaking world, opinar is a word that echoes through various layers of society. From the bustling streets of São Paulo to the quiet cafés of Lisbon, you will encounter this verb in countless contexts. One of the most prominent places you will hear 'opinar' is in the mass media. Television news programs, talk shows, and radio broadcasts are filled with 'comentaristas' (commentators) who are specifically invited to 'opinar' on the day's events. Whether the topic is the economy, sports, or international relations, the act of 'opinar' is central to the format of these programs.

News and Media
Journalists often use 'opinar' when introducing a guest: 'Estamos aqui com o Professor Silva para opinar sobre a crise.' This frames the guest as an expert whose thoughts carry weight. In newspapers, the 'Opinião' section is where columnists 'opinam' on controversial topics, shaping public discourse.

O jornalista pediu ao público para opinar através das redes sociais.

Another frequent setting is the workplace. During meetings, a manager might say, 'Gostaria que todos opinassem sobre a nova estratégia.' This is an invitation for collaboration and feedback. In this context, 'opinar' is a professional tool for improvement. It suggests that the employee's input is valued and necessary for the company's success. Similarly, in academic settings, professors encourage students to 'opinar' during seminars, fostering a culture of critical thinking and debate.

Online and Social Media
The digital age has significantly increased the frequency of 'opinar.' On platforms like Twitter (X), Instagram, and Facebook, the comment section is a primary space for people to 'opinar.' You will often see calls to action like 'Deixe seu comentário e opine!' This usage reflects the democratized nature of modern communication, where everyone has a platform to share their views.

Nas redes sociais, todos se sentem no direito de opinar sobre tudo.

In legal and governmental settings, 'opinar' has a technical meaning. When a public prosecutor or a legal consultant issues a 'parecer' (a formal legal opinion), they are said to 'opinar.' This is a high-stakes usage where the 'opinião' can influence the outcome of a trial or the implementation of a law. You might hear this in news reports about high-court decisions or legislative debates. It underscores the verb's connection to judgment and authority.

Daily Social Life
Finally, in daily social life, 'opinar' is used when making group decisions. Whether it's choosing a restaurant for dinner or deciding on a vacation destination, friends and family members will 'opinar.' It is the engine of collective decision-making. 'O que você opina?' (What do you opine/think?) is a common way to ask for someone's input in these situations.

Não vou opinar na escolha do seu vestido, a decisão é sua.

O técnico de futebol evitou opinar sobre a atuação do árbitro.

From the highest courts to the casual dinner table, 'opinar' is a verb that facilitates the flow of ideas. It is a word that invites participation and signals that a person's thoughts are being shared with the world. By paying attention to where you hear 'opinar,' you can learn a lot about the values and social dynamics of Portuguese-speaking cultures.

While opinar is a regular verb and relatively easy to conjugate, learners of Portuguese often stumble over its usage in specific ways. One of the most frequent errors is confusing 'opinar' with 'achar.' While both relate to thinking, 'achar' is far more common for expressing subjective, immediate feelings or beliefs. For example, 'Eu acho que vai chover' (I think it will rain) is natural, whereas 'Eu opino que vai chover' sounds unnaturally formal and slightly odd in a casual context. 'Opinar' should be reserved for when you are providing a more considered viewpoint or a formal judgment.

Preposition Errors
Another common mistake involves the prepositions that follow 'opinar.' Many learners try to use 'em' (in) or 'de' (of/from) incorrectly. The correct preposition is almost always 'sobre' (about). For example, saying 'opinar no projeto' is a common mistake; it should be 'opinar sobre o projeto.' While 'opinar de' can sometimes be heard in very specific regional dialects or older literature, 'sobre' is the standard and safest choice for all learners.

Incorrect: Eu opino de que o plano é ruim.

Correct: Eu opino que o plano é ruim.

A third mistake is using 'opinar' when 'sugerir' (to suggest) or 'aconselhar' (to advise) would be more appropriate. If you are telling someone what they *should* do, 'opinar' might be too passive. 'Eu opino que você deve ir' (I opine that you should go) is less direct than 'Eu sugiro que você vá' (I suggest that you go). 'Opinar' focuses on the thought itself, while 'sugerir' focuses on the action being proposed. Understanding this distinction helps in choosing the right verb for the desired impact.

Confusing with 'Opinar' in Spanish
For those who speak Spanish, the verb 'opinar' is very similar and often used in the same way. However, in Spanish, 'opinar' is used even more frequently in daily life where a Portuguese speaker might prefer 'achar.' Learners with a Spanish background should be careful not to over-use 'opinar' in Portuguese, which can make them sound overly formal or 'bookish' in casual conversations.

Incorrect: Ele opinou em mim.

Correct: Ele opinou sobre mim.

In writing, a common mistake is the omission of the 'que' when followed by a clause. Just like in English where we can say 'I think that...' or 'I think...', in Portuguese, the 'que' is mandatory after 'opinar' when a verb follows. 'Ele opinou que era tarde' is correct, whereas 'Ele opinou era tarde' is ungrammatical. This is a common slip for English speakers who are used to dropping the 'that'.

Overuse in Personal Contexts
Lastly, be wary of using 'opinar' too much when discussing very personal feelings. Using 'opinar' to talk about how much you love your partner or how you feel about a family member can sound clinical. In these cases, verbs like 'sentir' (to feel) or 'achar' are much more natural and emotionally appropriate.

Muitas vezes, é melhor ouvir do que opinar sem pensar.

Evite opinar se você não tem certeza dos dados apresentados.

By being aware of these common pitfalls—the confusion with 'achar,' the incorrect prepositions, and the overuse in casual contexts—you can use 'opinar' with greater accuracy and naturalness. Pay attention to how native speakers use it in different scenarios, and you will soon develop an intuitive feel for this important verb.

To truly enrich your Portuguese vocabulary, it is essential to understand the synonyms and alternatives to opinar. While 'opinar' is a very useful word, using it repeatedly can make your speech or writing repetitive. Depending on the context—whether formal, informal, or academic—different verbs can provide a more precise meaning. For example, 'achar' is the most common informal alternative, used for everyday thoughts and feelings.

Achar vs. Opinar
'Achar' is subjective and casual. 'Eu acho que ele vem' (I think he's coming). 'Opinar' is more formal and implies a stated viewpoint. 'O consultor opinou que o mercado está instável' (The consultant gave the opinion that the market is unstable). Use 'achar' for guesses and 'opinar' for judgments.

Em vez de apenas opinar, ele decidiu agir.

In more formal or professional contexts, verbs like 'manifestar-se' (to manifest oneself/to voice an opinion) or 'pronunciar-se' (to pronounce oneself/to make an official statement) are excellent alternatives. These verbs carry a sense of officialdom. For instance, 'O governo ainda não se pronunciou sobre o ocorrido' (The government has not yet made a statement about the occurrence). These are often used in news reports and formal documents where 'opinar' might sound too simple.

Julgar and Considerar
'Julgar' (to judge) and 'considerar' (to consider) are also related. 'Julgar' implies a more critical or evaluative stance: 'Eu julgo que esta medida é necessária' (I judge that this measure is necessary). 'Considerar' is often used to express a considered opinion: 'Nós consideramos que o projeto foi um sucesso' (We consider that the project was a success).

Ela não quis se pronunciar antes de ler o relatório completo.

Another interesting alternative is 'comentar' (to comment). While 'opinar' focuses on the judgment, 'comentar' focuses on the act of talking about something. If you are just adding information or making an observation, 'comentar' is the better choice. 'Ele comentou sobre o tempo' (He commented on the weather). If he were giving a judgment on whether the weather was good for the crops, he might 'opinar'.

Sugerir and Propor
When your opinion includes a recommended course of action, 'sugerir' (to suggest) or 'propor' (to propose) are more active and direct. 'Eu proponho que mudemos o horário' (I propose that we change the time) is more effective than 'Eu opino que o horário deve mudar' in a business setting.

O crítico de arte resolveu comentar cada detalhe da exposição.

Não é preciso opinar em tudo o que você vê na internet.

By expanding your range of verbs beyond 'opinar,' you can tailor your Portuguese to exactly the right level of formality and intent. Whether you are judging, suggesting, commenting, or officially pronouncing yourself, having these alternatives at your disposal will make you a more versatile and effective communicator.

How Formal Is It?

Le savais-tu ?

In ancient Rome, the word was often used in philosophical contexts to distinguish 'opinio' (subjective belief) from 'scientia' (proven knowledge). This distinction still exists today in the way we use 'opinar' for subjective views.

    You don't need the 'de' before 'que' when using 'opinar' to introduce a clause.

  • Opinar em o livro. Opinar sobre o livro.

    The preposition 'em' is incorrect here; 'sobre' is the standard choice.

  • Eu opino que vai chover. Eu acho que vai chover.

Astuces

Use 'Sobre'

Always remember to use 'sobre' after 'opinar' when you want to say what the opinion is about. It’s the most natural connection.

Achar vs Opinar

Use 'achar' for 90% of casual 'I think' situations. Save 'opinar' for when you want to sound more serious or when you are specifically asked for your view.

Regular Verb

Since it's a regular -ar verb, you can apply everything you know about 'falar' or 'trabalhar' to 'opinar'. This makes it easy to use in different tenses.

Ask First

Using 'Posso opinar?' is a great way to show respect in a group conversation before sharing your thoughts.

Watch the News

Portuguese news is a great place to hear 'opinar' used correctly. Look for segments where experts are interviewed.

Academic Tone

In essays, replace 'Eu acho' with 'Pode-se opinar que...' to make your writing sound much more professional.

Stress the End

Make sure the 'NAR' part is the strongest part of the word. O-pi-NAR.

Learn 'Pitaco'

If you are in Brazil, learning 'dar pitaco' will help you understand casual conversations much better.

Listen for 'Que'

When you hear 'opinou que...', you know a statement of belief or fact is coming next.

Workplace Usage

In a job interview or meeting, 'opinar' shows you are proactive and have professional judgments to share.

Mémorise-le

Moyen mnémotechnique

Association visuelle

Défi

Try to use the verb 'opinar' in three different tenses today: once in the present to a friend, once in the past about a movie, and once in the future about a plan.

Origine du mot

From the Latin verb 'opinari', which means to think, to suppose, or to have an opinion. It has roots in the Proto-Indo-European *op- meaning 'to choose' or 'to believe'.

Sens originel : The original Latin meaning was closer to 'to hold as a belief' or 'to conjecture', reflecting a mental state of uncertainty or subjective judgment.

Romance language family, derived directly from Latin, sharing cognates with Spanish 'opinar', French 'opiner', and Italian 'opinare'.

Contexte culturel

Be careful when 'opinando' on sensitive topics like religion or family in more traditional Portuguese-speaking environments. While expression is valued, respect for hierarchy and tradition is also important.

English speakers might find 'opinar' more common in Portuguese than 'opine' is in English. We often use 'think' or 'say', but Portuguese speakers love the specificity of 'opinar'.

The 'Opinião' show in Brazil (1964) was a famous musical protest against the dictatorship. Many Portuguese newspapers have a section called 'Espaço de Opinião'. The phrase 'Opinar é livre' is a common defense of free speech.
