plástico 30秒で
- Plástico means plastic, a common synthetic material.
- Used for bottles, toys, packaging, and more.
- It's a masculine noun in Portuguese.
- Essential for discussing everyday objects and environmental issues.
The Portuguese word 'plástico' refers to plastic, a widely used synthetic material. It's a term you'll encounter in everyday life, from describing objects made of this material to discussing environmental issues related to its production and disposal. Think about the many things around you: bottles, bags, toys, furniture, electronic casings, and even some clothing items. All of these can be made of plástico. In a broader sense, 'plástico' can also be used metaphorically to describe something that is easily molded or shaped, though this usage is less common than its literal meaning. When you're shopping, you might see labels indicating if a product is made of 'plástico.' When discussing recycling, 'plástico' is a key category. Even in art and design, artists use 'plástico' for sculptures and installations. It's a fundamental word for understanding the material world in Portuguese-speaking cultures. Consider the packaging in a supermarket, the components of a car, or the construction materials used in modern buildings; plastic is often a significant element. The word is versatile and applies to a vast array of items that are part of our daily routines. It's important to recognize its prevalence in discussions about sustainability and the circular economy, as well as in manufacturing and consumer goods. The sheer volume of plastic produced globally means this word is a constant presence in news reports, scientific studies, and general conversations about our environment and the objects we use. From single-use items to durable goods, 'plástico' covers a spectrum of applications, making it an essential vocabulary item for anyone learning Portuguese.
- Literal Meaning
- A synthetic material that can be molded into various forms, commonly used for making objects.
- Common Objects
- Bottles, bags, toys, furniture, packaging, electronic components.
- Environmental Discussions
- Recycling, pollution, sustainability, single-use items.

Precisamos de reduzir o uso de plástico descartável.
- Everyday Objects
- Many everyday items are made from plastic, such as cutlery, containers, and toys.
- Industrial Use
- Plastic is a key material in industries like automotive, electronics, and construction.
- Environmental Impact
- Discussions about plastic often revolve around its environmental impact, including pollution and recycling efforts.
Using 'plástico' in sentences is straightforward, especially when referring to the material itself. It functions as a masculine noun. You'll often see it used with articles like 'o' (the) or 'um' (a/an). For example, 'Eu comprei um copo de plástico' means 'I bought a plastic cup.' Here, 'de plástico' specifies the material of the cup. When discussing plastic in a general sense, you might say 'O plástico é um material muito usado' ('Plastic is a widely used material'). In sentences discussing recycling, you might hear or read 'Separe o lixo de plástico' ('Separate the plastic waste'). It's also common to use it when describing the properties or issues associated with plastic, such as 'A poluição por plástico é um problema global' ('Plastic pollution is a global problem'). When referring to multiple plastic items, the plural form 'plásticos' is used. For instance, 'Existem muitos tipos de plásticos' ('There are many types of plastics'). Consider how it appears in instructions or descriptions: 'Esta embalagem é feita de plástico reciclado' ('This packaging is made of recycled plastic'). In conversations about consumer goods, someone might ask, 'Este brinquedo é seguro? É feito de plástico?' ('Is this toy safe? Is it made of plastic?'). When talking about the environmental impact, a common phrase is 'Evite usar sacos de plástico' ('Avoid using plastic bags'). The word is also used in contexts related to manufacturing and production: 'A indústria de plástico está a crescer' ('The plastic industry is growing'). Understanding these common patterns will help you integrate 'plástico' naturally into your Portuguese conversations and writing. Remember that 'plástico' itself is the noun for the material, and it can be combined with other nouns to form compound descriptions, like 'mesa de plástico' (plastic table) or 'cadeira de plástico' (plastic chair). The context will usually make it clear whether you're talking about the material in general or specific items made from it.
A cadeira de plástico é leve.
- Material Specification
- Used with 'de' to specify the material of an object: 'copo de plástico' (plastic cup).
- General Statements
- Referring to plastic as a material: 'O plástico é durável' (Plastic is durable).
- Environmental Context
- Discussing issues related to plastic: 'Reciclagem de plástico' (Plastic recycling).
Este produto não contém plástico.
Os plásticos podem ser reciclados.

You will hear the word 'plástico' in a multitude of everyday situations. When you are grocery shopping, cashiers might ask you if you need a 'saco de plástico' (plastic bag) or if you want to use your own reusable bag. In a restaurant, especially a casual one, cutlery or takeaway containers might be made of 'plástico'. If you are buying children's toys, the packaging or the toys themselves will almost certainly be described as 'plástico'. When discussing household items, such as cleaning supplies or storage containers, 'plástico' will frequently come up. For example, someone might say, 'Preciso de uma caixa de plástico para organizar as minhas coisas' ('I need a plastic box to organize my things'). In conversations about environmental issues, which are increasingly common, 'plástico' is a central term. You'll hear about 'reciclagem de plástico' (plastic recycling), 'reduzir o uso de plástico' (reducing plastic use), and the impact of 'poluição por plástico' (plastic pollution). News reports and documentaries often feature this word when discussing waste management and conservation efforts. Even in construction and DIY contexts, you might hear about 'tubos de plástico' (plastic pipes) or 'perfis de plástico' (plastic profiles). When ordering furniture, especially outdoor or budget-friendly options, you'll encounter items like 'mesa de plástico' (plastic table) or 'cadeira de plástico' (plastic chair). In workshops or studios, artists might discuss using 'plástico' for sculptures or crafts. Travelers might hear it when renting cars, as many interior components are made of plastic. The word is so ubiquitous that it's part of the fundamental vocabulary for describing manufactured goods and materials in Portuguese-speaking countries. Listen for it in advertisements for consumer products, in discussions about packaging materials, and during any conversation where the composition of an object is relevant. It's a word that bridges the gap between the tangible world and the language used to describe it.
Posso ter um copo de plástico, por favor?
- Shopping
- Asked if you need a 'saco de plástico' (plastic bag).
- Restaurants
- Describing disposable cutlery or containers.

One common mistake for learners is with gender agreement. Remember that 'plástico' is a masculine noun. Therefore, any article or adjective modifying it must also be masculine. For instance, saying 'a plástico' instead of 'o plástico' would be incorrect. Similarly, using feminine adjectives like 'boa' when describing 'plástico' would be a mistake; it should be 'bom' if applicable (though 'plástico' itself doesn't typically take descriptive adjectives like 'good' in its basic form). Another potential pitfall is confusing the material 'plástico' with the adjective 'plástico' in English, which can mean 'fake' or 'artificial' in a negative sense. While the Portuguese word 'plástico' can sometimes imply something artificial, its primary meaning is the material itself. Avoid using it to describe someone's personality or behavior as 'fake' unless the context is very specific and nuanced, which is rare at the beginner level. Instead, stick to its material meaning. Learners might also struggle with the plural form. While 'plástico' is the singular for the material, when referring to different types of plastic or multiple plastic items, the plural 'plásticos' is used. Using 'plástico' when you mean 'plásticos' (e.g., 'Many plásticos are recycled') would be a grammatical error. When forming phrases like 'made of plastic,' ensure you use the correct preposition. The standard construction is 'feito de plástico' or 'de plástico.' Using other prepositions might sound unnatural. For example, 'feito em plástico' is generally incorrect. Finally, be mindful of context. While 'plástico' is almost always about the material, in very rare, informal contexts, it could be used metaphorically. However, for A1 learners, focusing on the literal meaning is crucial. Don't try to force metaphorical translations from English; learn how 'plástico' is used authentically in Portuguese. For instance, if you want to say something is 'malleable' or 'flexible' in a non-material sense, you'd likely use different Portuguese words. So, the key is to consistently associate 'plástico' with the physical substance.
Incorrecto: A garrafa é a plástico.
Correcto: A garrafa é de plástico.
- Gender Agreement
- Forgetting that 'plástico' is masculine and using feminine articles or adjectives.
- Plural Form
- Using the singular 'plástico' when referring to multiple types or items of plastic ('plásticos').
- Preposition Usage
- Incorrectly using prepositions like 'em' instead of 'de' when saying 'made of plastic'.
Incorrecto: Eu tenho muitos plástico em casa.
Correcto: Eu tenho muitos plásticos em casa.
While 'plástico' is the most common and direct translation for plastic, there are other terms and phrases that might be used depending on the context, although they are not direct synonyms for the material itself. For specific types of plastic, you might encounter terms like 'polietileno' (polyethylene) or 'PVC' (Polyvinyl chloride), but these are technical terms. When referring to the general concept of synthetic materials, you might hear 'material sintético,' but this is broader than just plastic. In some contexts, particularly when discussing packaging, you might hear 'embalagem plástica' (plastic packaging), which specifies the type of packaging. However, 'plástico' itself is the core word. If you are describing something that is not made of plastic, you would use nouns for other materials, such as 'vidro' (glass), 'metal' (metal), 'madeira' (wood), 'papel' (paper), or 'tecido' (fabric). For example, instead of 'copo de plástico,' you could say 'copo de vidro' (glass cup). When discussing the environmental impact, terms like 'lixo' (trash/waste) or 'resíduo' (residue) are often used in conjunction with 'plástico,' as in 'lixo plástico' (plastic waste). However, these refer to the waste product, not the material itself. In informal speech, people might refer to a specific plastic item with a more general term if the material is obvious, but 'plástico' remains the most precise word for the substance. It's important to distinguish 'plástico' (the material) from words that describe its properties. For instance, if something is flexible, you might use 'flexível,' but that's an adjective, not a noun for a material. Therefore, 'plástico' is the primary and most essential term for this material in Portuguese. When you need to specify the material of an object, 'de plástico' is the standard phrase. For instance, 'uma faca de plástico' (a plastic knife), 'uma mesa de plástico' (a plastic table). Understanding these nuances will help you use the word accurately and avoid confusion with other related concepts.
- Related Terms
- 'Embalagem plástica' (plastic packaging) is more specific. 'Material sintético' (synthetic material) is broader.
- Alternatives for Other Materials
- 'Vidro' (glass), 'metal' (metal), 'madeira' (wood), 'papel' (paper), 'tecido' (fabric) are used for non-plastic items.
- Waste Context
- 'Lixo plástico' (plastic waste) refers to discarded plastic items.
Esta mesa é de plástico, não de madeira.

よくある質問
10 問'Plástico' is a masculine noun in Portuguese. This means that articles and adjectives used with it should also be masculine. For example, you would say 'o plástico' (the plastic) and 'um plástico' (a plastic item), and potentially use masculine adjectives if describing a specific plastic item, like 'um copo de plástico resistente' (a resistant plastic cup).
The most common way to say 'made of plastic' is 'feito de plástico'. You can also simply use 'de plástico' after the noun it describes. For example, 'uma garrafa de plástico' means 'a plastic bottle', and 'A garrafa é feita de plástico' means 'The bottle is made of plastic'.
The plural of 'plástico' is 'plásticos'. You use the plural form when referring to multiple types of plastic, or multiple items made of plastic. For example, 'Existem muitos tipos de plásticos no mundo' (There are many types of plastics in the world).
While the English word 'plastic' can sometimes imply artificiality or superficiality, the Portuguese word 'plástico' primarily refers to the material itself. While context can sometimes allow for metaphorical interpretations, it's safer for learners to stick to the literal meaning of the material unless they encounter very clear idiomatic usage.
Many everyday objects are made of plastic, including bottles (garrafas), bags (sacos), cups (copos), toys (brinquedos), packaging (embalagens), furniture (móveis como cadeiras e mesas), and electronic components.
In environmental contexts, 'plástico' is often used in phrases like 'poluição por plástico' (plastic pollution), 'lixo plástico' (plastic waste), 'reciclagem de plástico' (plastic recycling), and 'uso de plástico' (use of plastic). It's central to discussions about sustainability and reducing waste.
Yes, just like in English, there are specific terms for different types of plastics, such as 'polietileno' (polyethylene) or 'PVC'. You might also hear about 'plástico reciclado' (recycled plastic) or 'plástico biodegradável' (biodegradable plastic), which describe the state or type of plastic.
'Plástico' specifically refers to plastic, a type of synthetic material. 'Material sintético' is a broader term that encompasses any material produced artificially, which could include plastics, synthetic fibers, etc.
The stress is on the first syllable: PLÁS-ti-co. The 'a' is an open sound (like 'ah' in 'father' or 'æ' in 'cat'), the 'i' is short (like in 'it'), and the final 'o' is a clear 'o' sound. Ensure the final 'k' sound is pronounced.
While plastic is often flexible, 'plástico' itself is the noun for the material. If you want to describe something as flexible, you would use the adjective 'flexível'. For example, 'Este material é flexível e parece plástico' (This material is flexible and looks like plastic).
