解析 pesquisa in your Level:
At the A1 level, 'pesquisa' is introduced as a basic noun related to finding information. Beginners learn it primarily in the context of using a computer or doing simple school tasks. At this stage, you should focus on the fact that it is a feminine noun ('a pesquisa') and that it is something you 'do' (fazer uma pesquisa). You might use it to say you are looking for a word in a dictionary or a place on a map. It is one of the essential words for survival in a digital environment, as you will see it on every search button on Portuguese websites. Don't worry about complex academic meanings yet; just think of it as the Portuguese word for 'a search'.

At this level, you should be able to describe your daily activities using the word, such as 'Eu faço uma pesquisa para o meu trabalho' (I am doing research for my work). You also learn to distinguish it from the verb 'procurar' (to look for), understanding that 'pesquisa' involves a more structured search for information rather than just finding a physical object.
By B1, you are expected to use 'pesquisa' in professional and academic discussions. You understand terms like 'pesquisa de mercado' (market research) and 'pesquisa de opinião' (opinion poll).

Your vocabulary expands to include common adjectives that go with 'pesquisa', such as 'pesquisa detalhada' (detailed research) or 'pesquisa rápida' (quick search). You are now using the word to express more complex ideas about data and evidence in conversation.

Your understanding of the word is now deeply integrated with your ability to process complex information in Portuguese.

You understand how the word functions in different Lusophone countries, noting the subtle preference for 'investigação' in certain Portuguese academic circles compared to the ubiquitous use of 'pesquisa' in Brazil. You use the word with precision, selecting it over synonyms to convey exactly the right level of formality and systematic intent.

You can participate in high-level academic or professional conferences, discussing 'paraditmas de pesquisa' (research paradigms) and 'pesquisa qualitativa vs. quantitativa'. You are aware of the historical etymology of the word and how it has evolved with technology. You can use the word in creative writing or complex rhetoric to imply a search for truth, meaning, or identity. Your usage is indistinguishable from a highly educated native speaker, and you can navigate the most complex texts in science, law, and literature where 'pesquisa' and its derivatives appear.

例句

pesquisa 30秒了解

  • Pesquisa is the Portuguese noun for 'research', 'search', or 'survey'.
  • It is a feminine noun, so you always say 'a pesquisa' or 'uma pesquisa'.
  • It is used in academic, digital, and commercial contexts to describe finding information.
  • The word implies a systematic or thorough effort rather than a casual look.

The Portuguese word pesquisa is a fundamental noun that translates most directly to 'research,' 'search,' or 'survey' in English. It is a feminine noun (a pesquisa) used to describe the systematic process of investigating a subject, looking for information, or gathering data to reach a conclusion. Whether you are a student writing a thesis, a scientist in a lab, or simply someone looking for the best price for a new smartphone on the internet, you are engaged in a pesquisa. This word is ubiquitous in Portuguese-speaking cultures because it bridges the gap between formal academic inquiry and everyday digital life.

Academic Context
In universities and research centers, 'pesquisa' refers to scientific investigation. It involves methodology, data collection, and analysis. For example, 'pesquisa científica' is the standard term for scientific research.
Digital Context
When using a search engine like Google, the act of typing a query is a 'pesquisa'. The search bar itself is often called the 'barra de pesquisa'.
Market and Opinion
In business and politics, 'pesquisa' refers to surveys and polls. A 'pesquisa de mercado' is market research, while a 'pesquisa de opinião' is an opinion poll used to gauge public sentiment.

A pesquisa acadêmica exige muito rigor e paciência por parte do pesquisador.

Fiz uma pesquisa rápida no Google e encontrei a resposta imediatamente.

A última pesquisa eleitoral indica um empate entre os candidatos principais.

Estamos realizando uma pesquisa de satisfação com todos os nossos clientes atuais.

O detetive continuou sua pesquisa por pistas no local do crime.

Beyond these uses, 'pesquisa' can also imply a sense of curiosity. When someone is 'em pesquisa' (researching), they are in a state of active discovery. It is more structured than a simple 'olhada' (a look) and more intellectual than a 'busca' (a search for a physical object). Understanding this word is key to navigating Brazilian and Portuguese intellectual life, media, and commerce. Whether you are filling out a survey at a mall or writing a scientific paper, 'pesquisa' is the term that defines your effort to find the truth or the best option among many.

Using pesquisa correctly requires understanding its role as a noun and its relationship with specific verbs. The most common verb paired with 'pesquisa' is fazer (to do/make), but more formal options like realizar (to carry out) or conduzir (to conduct) are frequently seen in professional contexts. Because it is a feminine noun, any adjectives modifying it must also be feminine, such as 'pesquisa detalhada' (detailed research) or 'pesquisa profunda' (deep research).

Common Verb Pairings
Fazer uma pesquisa (To do research), Realizar uma pesquisa (To carry out a survey), Publicar uma pesquisa (To publish research), Iniciar uma pesquisa (To start a search).
Prepositional Usage
Usually followed by 'sobre' (about) or 'de' (of/regarding). Example: 'Pesquisa sobre o clima' (Research about the climate) or 'Pesquisa de mercado' (Market research).

Eles estão fazendo uma pesquisa exaustiva sobre a história da cidade.

A pesquisa de campo será realizada no próximo mês na Amazônia.

Você já terminou a sua pesquisa bibliográfica para o TCC?

In everyday conversation, if you want to say 'I looked it up,' you would use the verb form: 'Eu pesquisei.' However, if you want to emphasize the effort or the result, you use the noun: 'Eu fiz uma pesquisa.' This distinction is subtle but important. 'Pesquisa' carries more weight than just 'looking'; it suggests a level of thoroughness. In a professional setting, always prefer 'pesquisa' to describe your information-gathering efforts. It sounds more professional and organized than simply saying you 'searched' (procurou) for something.

You will encounter pesquisa in a variety of settings across the Lusophone world. In the media, it is perhaps most prominent during election cycles. News anchors will frequently report on 'pesquisas eleitorais' to show which candidate is leading. In these contexts, the word is synonymous with 'polling' and 'data analysis.' You will also hear it in every university hallway in Brazil or Portugal, as professors and students discuss their 'projetos de pesquisa' (research projects).

In the News
'Segundo a pesquisa Datafolha...' (According to the Datafolha survey...). This is a very common way to cite statistics in Brazilian media.
In Technology
On websites, look for the magnifying glass icon; it is usually labeled 'Pesquisar' (verb) or 'Campo de Pesquisa' (noun field).

A pesquisa indica que a maioria da população apoia a nova lei.

Recebi um e-mail para participar de uma pesquisa de usuário do aplicativo.

In corporate environments, 'pesquisa e desenvolvimento' (R&D) is a standard department name. If you work in marketing, tech, or science, this word will be part of your daily vocabulary. Even in social situations, if someone makes a bold claim, a common skeptical response might be: 'Qual é a sua fonte? Onde está a pesquisa que prova isso?' (What is your source? Where is the research that proves that?). This shows how 'pesquisa' is linked to the concepts of evidence and validation in Portuguese culture. It is a word that commands respect because it implies that someone has done the hard work of looking for the truth rather than just guessing.

One of the most frequent mistakes English speakers make is confusing pesquisa with procura or busca. While all three involve looking for something, they are not interchangeable. 'Busca' is often used for physical searches (like looking for lost keys) or police searches (busca e apreensão). 'Procura' often refers to the demand for a product or the general act of looking for something or someone. 'Pesquisa' is specifically for information, data, or systematic study.

Gender Mismatch
Avoid saying 'o pesquisa'. It is always 'a pesquisa'. This is a common error for learners who assume abstract nouns might be masculine.
Confusing with 'Investigação'
While 'investigação' is a synonym, in Portuguese it often carries a criminal or legal connotation. For school or work projects, 'pesquisa' is usually the safer, more common choice.

Errado: Eu fiz um pesquisa sobre o tema. (Wrong gender)

Correto: Eu fiz uma pesquisa sobre o tema.

Another mistake is using the word 'pesquisa' when you simply mean 'searching' in a casual sense. If you are looking for your shoes, don't say 'estou fazendo uma pesquisa pelos meus sapatos.' Instead, say 'estou procurando meus sapatos.' Use 'pesquisa' when the activity involves gathering information, reading, or analyzing data. Also, be careful with the preposition. It's 'pesquisa sobre' or 'pesquisa de', never 'pesquisa em' unless you are referring to the location where the research is happening (e.g., 'pesquisa na universidade').

To enrich your Portuguese, it is helpful to know the nuances between pesquisa and its synonyms. While 'pesquisa' is the most versatile term, other words can provide more specific meanings depending on the context of your investigation.

Investigação
More formal and often used for police work or deep scientific inquiry. It implies a detailed, forensic-like approach.
Estudo
A 'study'. While research is an investigation, a study is often the result or the focused application of that research on a specific case.
Sondagem
Specifically used for polls or 'testing the waters'. It is less rigorous than a full 'pesquisa' and more about getting a quick sense of a situation.
Levantamento
Refers to the act of gathering or surveying data/resources. Often used in logistics or initial project phases (e.g., levantamento de dados).

A investigação criminal durou meses antes de encontrarem o culpado.

Fizemos uma sondagem informal entre os funcionários para saber a opinião deles.

In academic writing, you might also see the term 'inquérito', which is often used for questionnaires or surveys in European Portuguese. In Brazil, 'questionário' is more common for the tool itself, while 'pesquisa' remains the name of the overall activity. By learning these alternatives, you can tailor your speech to sound more natural and precise in different Portuguese-speaking environments.

趣味小知识
