precisão في 30 ثانية
- Precisão means exactness and accuracy.
- It's used when something is free from errors.
- Think of precise measurements or instructions.
- It's a feminine noun in Portuguese.
- Definition
- Precisão refers to the quality of being exact, accurate, and free from error. It is about how closely something matches a standard, a measurement, or the intended result. When we talk about precisão, we are emphasizing the absence of mistakes, vagueness, or deviations.
- Usage Contexts
- This word is frequently used in contexts where accuracy is important. This includes scientific experiments, technical measurements, data analysis, crafting detailed instructions, financial reporting, and even in artistic endeavors where exactness in detail matters. For example, a surgeon needs great precisão in their work, a scientist requires precisão in their measurements, and a programmer needs precisão in their code. It implies a high level of care and attention to detail to achieve a correct and reliable outcome. In everyday life, we might speak of the precisão of a clock, the precisão of a GPS system, or the precisão with which someone described an event. The opposite of precisão would be imprecisão, vagueness, or error. It is a fundamental concept in fields that rely on reliable data and outcomes, ensuring that what is stated or done is exactly as it should be.
A ferramenta de medição precisa demonstrar alta precisão para garantir resultados confiáveis.
A precisão dos dados é crucial para a tomada de decisões informadas.
- Synonym Focus
- While 'exatidão' is a very close synonym, 'precisão' often implies a more active process of achieving or maintaining that exactness, especially in measurements or actions. 'Acurácia' also relates to correctness, but 'precisão' often emphasizes the repeatability and reliability of a measurement or process.

A precisão cirúrgica é essencial para o sucesso da operação.
- Basic Structure
- 'Precisão' is a feminine noun. It is often used with articles like 'a' (the) or 'uma' (a/an), or with possessive adjectives. It can be the subject of a sentence, the object, or part of a prepositional phrase. Common verbs that accompany 'precisão' include 'ter' (to have), 'demonstrar' (to demonstrate), 'exigir' (to require), 'garantir' (to guarantee), 'alcançar' (to achieve), and 'perder' (to lose).
O relojoeiro trabalha com grande precisão.
- Subject of the Sentence
- When 'precisão' is the subject, it describes a quality or characteristic of something. For example, 'A precisão deste mapa é impressionante.' (The precision of this map is impressive.) Here, 'precisão' is the noun being described by 'impressionante'.
A precisão do diagnóstico médico pode salvar vidas.
- Object of the Verb
- 'Precisão' can also be the direct object of a verb, indicating what is achieved or required. For instance, 'Os engenheiros buscam a máxima precisão no projeto.' (The engineers seek maximum precision in the project.) In this case, 'precisão' is what the engineers are seeking.
Precisamos de mais precisão nas nossas estimativas.
- In Prepositional Phrases
- It frequently appears in prepositional phrases, often with 'com' (with) or 'de' (of). Examples include 'com precisão' (with precision) or 'falta de precisão' (lack of precision). 'Ele realizou o trabalho com grande precisão.' (He carried out the work with great precision.)
A falta de precisão na comunicação causou mal-entendidos.
A precisão dos cálculos é fundamental.
- Technical and Scientific Fields
- You will hear 'precisão' frequently in discussions about science, engineering, and technology. Researchers talk about the 'precisão dos instrumentos de medição' (precision of measuring instruments), doctors discuss the 'precisão de um diagnóstico' (precision of a diagnosis), and engineers debate the 'precisão de um projeto' (precision of a design). When someone is explaining how a complex machine works, or the results of an experiment, the word 'precisão' is likely to come up to highlight the exactness of the measurements or the outcome.
A precisão dos dados coletados é essencial para a pesquisa.
- Manufacturing and Craftsmanship
- In workshops and factories, 'precisão' is a key concept. A craftsman might take pride in the 'precisão com que cortou a madeira' (precision with which they cut the wood), or a factory manager might emphasize the 'precisão na linha de produção' (precision on the production line) to ensure product quality and consistency. This applies to everything from making intricate jewelry to assembling large machinery.
A precisão na fabricação de peças garante o encaixe perfeito.
- Academic and Educational Settings
- In schools and universities, teachers often stress the importance of 'precisão' in written work, mathematical calculations, and scientific reporting. Students might be asked to 'escrever com precisão' (write with precision), meaning to be clear, exact, and avoid ambiguity. The quality of a student's work is often judged by its level of 'precisão'.
O professor elogiou a precisão da resposta do aluno.
- Everyday Discussions
- Even in casual conversation, 'precisão' can be used. Someone might complain about the 'falta de precisão' in a news report, or praise the 'precisão' of a GPS navigation system. If someone gives you directions, you might comment on their 'precisão' if they are very clear and detailed. It's a word that signifies reliability and exactness across many aspects of life.
A precisão do GPS ajudou-nos a encontrar o caminho rapidamente.
É importante ter precisão ao preencher formulários.
- Confusing with 'Exatidão' or 'Acurácia'
- While 'precisão', 'exatidão', and 'acurácia' are related, they aren't always interchangeable. 'Precisão' often implies consistency and repeatability in measurement, even if the measurement is systematically off from the true value (e.g., a scale that consistently reads 1kg too high but is always off by exactly 1kg). 'Exatidão' refers to how close a measurement is to the true value. 'Acurácia' is a broader term often used for correctness and closeness to truth. A common mistake is using 'precisão' when 'exatidão' is more appropriate, or vice-versa. For example, saying 'A precisão do meu peso está errada' is less accurate than 'A exatidão do meu peso está errada' (if the scale is consistently wrong) or 'A minha balança não tem precisão' (if the readings fluctuate wildly).
Mistake: A precisão deste relógio é horrível, ele atrasa uma hora por dia.
Correct: A exatidão deste relógio é horrível, ele atrasa uma hora por dia.
- Gender Agreement
- Since 'precisão' is a feminine noun, any adjectives modifying it must also be feminine. A common error is to use masculine adjectives. For example, saying 'um precisão' instead of 'uma precisão', or using an adjective like 'alto' instead of 'alta'. Always remember that 'precisão' is feminine and requires feminine agreement.
Mistake: Ele tem um precisão incrível no desenho.
Correct: Ele tem uma precisão incrível no desenho.
- Overuse or Misapplication
- Sometimes learners might use 'precisão' when a simpler word like 'correto' (correct) or 'exato' (exact) would suffice, especially in less technical contexts. While not strictly an error, it can sound overly formal or out of place. For instance, asking for 'a precisão da sua opinião' (the precision of your opinion) is less natural than asking for 'a clareza da sua opinião' (the clarity of your opinion) or 'a exatidão dos seus fatos' (the accuracy of your facts).
Overuse: A precisão da sua sugestão é muito útil.
Better: A utilidade da sua sugestão é muito grande.
- Exatidão
- 'Exatidão' is probably the closest synonym to 'precisão'. Both refer to correctness and accuracy. However, 'precisão' often emphasizes the quality of being exact in measurements or procedures, implying a high degree of care and detail in execution. 'Exatidão' can be a more general term for being correct or true. For instance, a clock might have 'precisão' if its hands move smoothly and consistently, but 'exatidão' if it tells the correct time.
Example: A precisão dos números é vital para a contabilidade. (The precision of the numbers is vital for accounting.) vs. A exatidão do resultado foi confirmada. (The accuracy of the result was confirmed.)
A precisão do instrumento garante medições repetíveis.
- Acurácia
- 'Acurácia' is also very close and often used interchangeably with 'exatidão' and sometimes 'precisão'. It refers to how close a measurement or statement is to the true value or reality. In scientific contexts, 'precisão' relates to the scatter of data points (how close they are to each other), while 'acurácia' relates to how close the average of those data points is to the true value. If a target is shot, tight grouping of shots is 'precisão', while the shots being near the bullseye is 'acurácia'.
Example: A acurácia da previsão do tempo foi surpreendente. (The accuracy of the weather forecast was surprising.) vs. A precisão do corte a laser é impressionante. (The precision of the laser cut is impressive.)
A acurácia do mapa nos ajudou a não nos perdermos.
- Rigor
- 'Rigor' refers to strictness, exactness, and thoroughness, especially in following rules, methods, or principles. While it shares the concept of exactness, it often implies a more formal adherence to standards or a severe application of rules. You might speak of 'rigor científico' (scientific rigor) or 'rigor na aplicação da lei' (rigor in the application of the law). It's less about the measurement itself and more about the strictness of the process.
Example: O estudo foi conduzido com grande rigor científico. (The study was conducted with great scientific rigor.) vs. A precisão do experimento foi garantida por protocolos estritos. (The precision of the experiment was guaranteed by strict protocols.)
O rigor matemático é essencial em física teórica.
- Clareza
- 'Clareza' means clarity or clearness. While clarity can contribute to precision (clear instructions lead to more precise actions), it's not the same. Clarity is about being easy to understand, free from ambiguity. Precision is about being exact and accurate. You can have a clear but imprecise statement, or a precise but unclear one (in very technical jargon).
Example: A clareza das instruções facilitou o trabalho. (The clarity of the instructions made the work easier.) vs. A precisão dos dados permitiu uma análise detalhada. (The precision of the data allowed for a detailed analysis.)
A clareza da sua explicação foi excelente.
How Formal Is It?
حقيقة ممتعة
The concept of 'cutting' or 'separating' from the Latin root 'caedere' is interesting because precision often involves defining boundaries or separating true values from errors. It's about making a clear and exact cut in reality or measurement.

مستوى الصعوبة
The word 'precisão' itself is relatively straightforward. However, its usage can become complex in technical or abstract contexts, requiring a good understanding of related terminology and sentence structure.
Using 'precisão' correctly requires careful attention to gender agreement and choosing the right synonym (e.g., 'exatidão', 'acurácia') for the specific context. Overuse or misapplication can lead to unnatural phrasing.
Pronunciation is manageable, and the core meaning is easy to grasp. Applying it naturally in conversation might require practice, especially in more formal settings.
The word is common enough in many contexts that it should be recognizable once learned. Its meaning is usually clear from the surrounding words.

While very similar, 'exatidão' often refers to closeness to the true value, while 'precisão' can refer to the consistency or repeatability of measurements, even if they are systematically off. Think of 'precisão' as repeatability and 'exatidão' as correctness.
'Acurácia' is often used as a synonym for 'exatidão' but can also encompass 'precisão' in a broader sense of overall correctness. In statistics, 'precisão' is about data spread, and 'acurácia' is about how close the mean is to the true value.
'Correto' is a more general term for 'correct'. 'Precisão' implies a higher degree of exactness and detail than simply being correct.

Both words mean accuracy and correctness. They are often used interchangeably in everyday language.
'Precisão' often highlights the consistency and repeatability of a measurement or process, emphasizing how closely repeated measurements agree with each other. 'Exatidão' focuses more on how close a measurement is to the true or actual value. A precise measurement might be consistently off by 1mm, while an exact measurement would be very close to the true value.
O instrumento tem alta precisão (as leituras são sempre muito próximas umas das outras), mas baixa exatidão (a média das leituras está longe do valor verdadeiro).
Very similar to 'exatidão', meaning correctness and closeness to the truth.

نصائح
English Connection
The Portuguese word 'precisão' is a direct cognate of the English word 'precision'. They share the same root and very similar meanings related to exactness and accuracy. This makes it one of the easier words to remember for English speakers.
Feminine Noun
'Precisão' is a feminine noun in Portuguese. Remember to use feminine articles ('a', 'uma') and adjectives (e.g., 'alta', 'grande') when referring to it. For example, 'uma grande precisão'.
Technical vs. General
While 'precisão' is used in general contexts, it's particularly important and frequently heard in technical, scientific, and professional fields where accuracy is paramount. Pay attention to these contexts to better understand its nuances.
Adverbial Phrase
The phrase 'com precisão' (with precision) is very common and useful for describing how an action is performed. For example, 'Ele descreveu o evento com precisão.'
Distinguishing from Synonyms
While 'exatidão' and 'acurácia' are close synonyms, remember that 'precisão' can sometimes emphasize consistency and repeatability, whereas 'exatidão' and 'acurácia' often focus more on closeness to the true value.
The 'são' Ending
The ending '-são' in 'precisão' is a nasal diphthong. Practice pronouncing it with a nasal quality, similar to the 'song' sound in English but more pronounced. The stress is on the 'são' syllable.
Visual Aid
Imagine a laser cutter making an incredibly exact line, or a surgeon using a very fine instrument. These visuals can help reinforce the meaning of 'precisão'.
Opposite Meaning
The direct opposite of 'precisão' is 'imprecisão' (imprecision or inaccuracy). Understanding the antonym can solidify the meaning of the word itself.
Practical Use
Try to use 'precisão' in your own sentences when talking about measurements, instructions, or any situation where exactness is important. The more you use it, the more natural it will become.
Degree of Exactness
'Precisão' implies a high degree of exactness. When you need to convey this, 'precisão' is the word to use, rather than a more general term like 'correto' (correct).
احفظها
وسيلة تذكّر
Think of a 'precise' pencil that can draw a very sharp line. The 'pre' sounds like 'pencil', and the 'cisão' sounds like 'cision' (as in decision, or precision). So, a 'pencil-cision' that makes a very exact line.

تحدٍّ
Try to describe a simple object in your room using as much 'precisão' as possible. For example, instead of 'a chair', say 'a wooden chair with four legs, a rectangular seat, and a high back with three vertical supports'.
أصل الكلمة
The word 'precisão' in Portuguese comes from the Latin word 'praecisio', which is the past participle of 'praecidere'. 'Praecidere' is formed from 'prae-' (before, in front of) and 'caedere' (to cut). Thus, the original literal meaning relates to cutting off or separating something beforehand, implying a distinctness or exactness.
المعنى الأصلي: To cut off beforehand; to make distinct or exact.

There are no significant cultural sensitivities associated with the word 'precisão' itself. It is a neutral term related to accuracy and exactness. However, the *consequences* of a lack of precision can be sensitive in certain fields, such as aviation safety, medical treatments, or financial reporting.
In English-speaking cultures, precision is also highly valued, particularly in scientific, technical, and business contexts. The concept of 'precision' in English is very close to the Portuguese 'precisão', making it a relatively straightforward cognate to understand. The emphasis on accuracy, data integrity, and detailed planning is common.

الأسئلة الشائعة
10 أسئلةThe most common meaning of 'precisão' is the quality of being exact and accurate. It's used when something is free from errors or deviations, especially in measurements, calculations, or descriptions.
In most technical, scientific, and professional contexts, 'precisão' is highly valued as it leads to reliable results and correct outcomes. However, in some artistic or creative contexts, absolute precision might not be the primary goal, and a certain degree of flexibility or interpretation might be preferred. In everyday life, excessive precision might sometimes seem pedantic.
'Precisão' often refers to the consistency or repeatability of a measurement – how close multiple measurements are to each other. 'Exatidão' refers to how close a measurement is to the true value. You can have high precision but low exatidão (e.g., a scale that consistently reads 2kg too high but always reads the same wrong value), or vice-versa.
Yes, 'precisão' can be used for abstract concepts, especially when referring to the exactness of language, thought, or argument. For example, 'a precisão da linguagem' (the precision of language) or 'a precisão do argumento' (the precision of the argument).
The plural of 'precisão' is 'precisões'. It is used when referring to different types or instances of precision, for example, 'as diversas precisões requeridas para a tarefa' (the various precisions required for the task).
'Precisão' is a feminine noun. Many abstract nouns ending in '-são' or '-ção' in Portuguese are feminine. You can remember this by associating it with the English word 'precision' and thinking of feminine qualities or by practicing sentences where it's used with feminine articles and adjectives.
Yes, very common ones include 'com precisão' (with precision/accurately), 'falta de precisão' (lack of precision), and 'alta precisão' (high precision). These phrases are frequently used in various contexts.
In scientific and statistical contexts, 'precisão' relates to the scatter or variability of measurements (how close they are to each other), while 'acurácia' refers to how close the measurements are to the true value. Think of 'precisão' as reproducibility and 'acurácia' as correctness against a standard.
Use 'precisão' when you want to emphasize a high degree of exactness, detail, and absence of error, especially in measurements or technical descriptions. 'Correto' is a more general term for being right or accurate, but it doesn't necessarily imply the same level of meticulousness as 'precisão'.
Technology often aims to enhance 'precisão'. For instance, GPS systems offer high navigational 'precisão', scientific instruments are designed for 'precisão de medição', and manufacturing processes rely on 'precisão' to create perfect components.
