Portuguese, like English, divides nouns into those you can count individually (um livro, dois livros, três livros) and those you cannot (água, paciência, ouro). The distinction is grammatical, not just conceptual: countable nouns take plural forms and combine freely with numerals, while uncountable (mass) nouns normally appear in the singular and resist being counted directly. What makes this topic worth a dedicated page is that Portuguese and English do not always agree on which nouns are countable — um conselho (a piece of advice) sounds perfectly natural in Portuguese, and duas águas (two waters) is what you order in a café. Getting the count/mass system right is a matter of knowing both the grammatical machinery and the cultural conventions that decide when a mass noun flips to countable.
The basic distinction
A countable noun (nome contável) names something that comes in discrete, individual units. You can count these units with numerals, pluralise them freely, and combine them with the indefinite article um/uma.
Comprei três livros na feira do livro.
I bought three books at the book fair.
An uncountable noun (nome incontável or nome massivo) names a substance, abstract concept, or undifferentiated mass that has no natural unit of counting. It normally appears in the singular without an indefinite article, and to quantify it you need a partitive construction (um copo de água, uma fatia de pão).
Preciso de mais tempo para acabar o relatório.
I need more time to finish the report.
Types of uncountable nouns
Uncountable nouns in Portuguese fall into several natural classes. Recognising which class a noun belongs to helps you predict how it behaves and which partitive construction it takes.
Concrete mass nouns (substances)
Liquids, grains, and undifferentiated substances are the prototypical mass nouns — a puddle of water has no natural "units" the way a pile of books does.
Queres água com gás ou sem gás?
Would you like sparkling or still water?
Falta leite no frigorífico — vou comprar amanhã.
There's no milk in the fridge — I'll buy some tomorrow.
Common examples: água (water), leite (milk), vinho (wine), cerveja (beer), café (coffee), pão (bread), arroz (rice), açúcar (sugar), sal (salt), azeite (olive oil), manteiga (butter).
Material mass nouns
Names of materials that can be shaped into objects but are themselves continuous substances.
Esta mesa é feita de madeira maciça de carvalho.
This table is made of solid oak wood.
O anel é de ouro — foi da minha avó.
The ring is gold — it was my grandmother's.
Common examples: madeira (wood), ouro (gold), prata (silver), ferro (iron), vidro (glass), plástico (plastic), papel (paper), tecido (fabric), pedra (stone).
Abstract mass nouns
Emotions, qualities, and abstract concepts are usually uncountable because they are states rather than objects.
Preciso de paz e sossego depois desta semana.
I need peace and quiet after this week.
Tem muita paciência com as crianças.
She has a lot of patience with the children.
Common examples: amor (love), paz (peace), felicidade (happiness), tristeza (sadness), paciência (patience), coragem (courage), sorte (luck), sabedoria (wisdom), tempo (time, in the sense of duration), saúde (health).
Collective mass nouns
Some nouns name a diffuse phenomenon or aggregate that has no natural unit even though it's made up of individual things.
Há sempre muito trânsito na ponte à hora de ponta.
There's always a lot of traffic on the bridge at rush hour.
O mobiliário da sala é todo novo — acabámos de mudar de casa.
The living room furniture is all new — we just moved house.
Common examples: trânsito (traffic), mobiliário (furniture), bagagem (luggage), roupa (clothing, as a mass), fruta (fruit, collective), correspondência (mail).
Partitive strategies: quantifying the unquantifiable
When you need to specify a quantity of a mass noun, Portuguese uses a partitive phrase — a countable measure word followed by de and the mass noun. This is the equivalent of English "a glass of water" or "a loaf of bread."
Posso pedir um copo de água, por favor?
Can I get a glass of water, please?
Comprámos duas garrafas de vinho tinto para o jantar.
We bought two bottles of red wine for dinner.
Come uma fatia de pão com queijo antes de sair.
Eat a slice of bread and cheese before you leave.
| Partitive | Used with | Example |
|---|---|---|
| um copo de | liquids (small) | um copo de água, um copo de leite |
| uma chávena de | hot drinks | uma chávena de café, uma chávena de chá |
| uma garrafa de | bottled liquids | uma garrafa de vinho, uma garrafa de azeite |
| uma fatia de | loaves, cakes, cheese | uma fatia de pão, uma fatia de bolo |
| um pedaço de | solid substances | um pedaço de madeira, um pedaço de queijo |
| uma porção de | food servings | uma porção de arroz, uma porção de batatas |
| um bocado de | anything, informal | um bocado de pão, um bocado de tempo |
| uma pitada de | seasonings | uma pitada de sal, uma pitada de açúcar |
| um quilo de | weighed items | um quilo de arroz, meio quilo de manteiga |
When mass nouns become countable
One of the trickiest features of the count/mass system is that many uncountable nouns shift to countable usage in specific contexts. When this happens, a new "unit" is implicit in the situation — and native speakers switch without thinking.
Ordering in cafés and restaurants
At a café, duas águas means "two bottles of water" or "two servings of water" — the implicit unit is a bottle or glass appropriate to the setting. This is standard PT-PT café speech.
Duas águas e um café, se faz favor.
Two waters and a coffee, please.
Trazes mais dois cafés para esta mesa?
Can you bring two more coffees to this table?
Vamos pedir duas cervejas e um sumo de laranja.
Let's order two beers and an orange juice.
Kinds or varieties
When a mass noun pluralises, it often means "kinds of" or "varieties of" the substance. Vinhos can mean "wines" (different types), queijos "cheeses" (a selection), águas "waters" (mineral waters of different brands or types).
Os vinhos do Douro são famosos em todo o mundo.
Douro wines are famous throughout the world.
Provámos vários queijos portugueses numa loja no Chiado.
We tried several Portuguese cheeses in a shop in Chiado.
Instances of abstract states
Pluralised abstract nouns usually denote instances or occurrences of the state rather than the state itself. Amor is the abstract feeling; amores are love affairs or romantic partners. Tempo is time in the abstract; tempos are specific eras.
Teve vários amores ao longo da vida, mas nunca casou.
He had several loves throughout his life but never married.
Nos tempos da minha avó, as coisas eram bem diferentes.
In my grandmother's time, things were very different.
Houve momentos de grande tristeza, mas também muitas alegrias.
There were moments of great sadness, but also many joys.
Where Portuguese and English disagree
Count/mass categories are not universal — they are conventions that each language settles differently. English speakers consistently misanalyse several Portuguese nouns as uncountable because their English translations are uncountable.
Conselho (advice) — countable in Portuguese
In English, "advice" is resolutely uncountable: you say a piece of advice, never *an advice. Portuguese treats conselho as a perfectly ordinary countable noun.
Deu-me dois bons conselhos sobre a entrevista.
She gave me two good pieces of advice about the interview.
Posso pedir-te um conselho?
Can I ask you for a piece of advice?
Informação (information) — both, depending on context
Informação is flexible. Uma informação means "a piece of information" and is completely natural in PT-PT; informação in the mass sense (for data or knowledge in general) is also common.
Tenho uma informação importante sobre a reunião de amanhã.
I have an important piece of information about tomorrow's meeting.
Precisamos de mais informação antes de tomar uma decisão.
We need more information before making a decision.
Mobília / mobiliário (furniture) — uncountable, like English
Both languages agree here: you cannot say *duas mobílias. To count, use peças de mobiliário (pieces of furniture).
A casa nova precisa de mais peças de mobiliário para a sala.
The new house needs more pieces of furniture for the living room.
Notícia (news/piece of news) — countable in Portuguese
English "news" is uncountable (a piece of news), but Portuguese notícia is a countable noun with a regular plural notícias.
Tenho uma boa notícia para te dar — fui aceite no mestrado!
I have some good news for you — I got accepted into the master's programme!
As notícias desta semana foram todas más.
The news this week has all been bad.
Pão (bread) — mostly uncountable, but countable for loaves
Pão is uncountable when you mean bread as a substance (pão de trigo), but countable when you mean individual rolls or loaves (um pão, dois pães). This is the opposite of English, where "bread" is always uncountable and you have to say "a loaf of bread."
Comprei dois pães na padaria esta manhã.
I bought two loaves at the bakery this morning.
Queres pão com o queijo?
Would you like bread with the cheese?
Articles with countable and uncountable nouns
Article use is one of the clearest signals of count/mass status, and the rules diverge between Portuguese and English.
Indefinite article is rare with true mass nouns
Portuguese normally does not combine um/uma with an uncountable noun unless you are specifying a kind or variety of the substance.
Preciso de café para começar o dia.
I need coffee to start the day.
Ofereceu-me um café excelente, importado da Colômbia.
He offered me an excellent coffee, imported from Colombia.
The second sentence uses um café because excelente, importado da Colômbia specifies a particular kind — the mass noun has effectively become a count noun for the purpose of this utterance.
Definite article is used for generic reference
Portuguese uses the definite article o/a when referring to a substance or abstract generically — which is different from English, where generic reference uses no article.
O dinheiro não traz felicidade.
Money doesn't bring happiness.
A paciência é uma virtude.
Patience is a virtue.
See Articles vs. No Article for the full rule.
Quantifiers that work with mass nouns
Some quantifiers pair only with countable nouns (muitos, poucos, alguns), while others pair only with mass nouns (muito, pouco, algum in the singular). A third group works with both.
| With countable (plural) | With uncountable (singular) | Meaning |
|---|---|---|
| muitos livros | muito dinheiro | many / a lot of |
| poucos amigos | pouco tempo | few / little |
| vários problemas | — | several (only countable) |
| alguns dias | algum dinheiro | some |
| nenhum livro | nenhum dinheiro | no / not any |
| todos os livros | todo o dinheiro | all the |
Tenho poucos amigos em Lisboa mas pouco tempo para os ver.
I have few friends in Lisbon but little time to see them.
A learner's strategy
When you encounter a new Portuguese noun, ask yourself: is this a substance, an abstract state, or an individual object? If it's clearly a substance or state, it's probably uncountable. If it's an individual object, it's probably countable. Then — and this is the important step — don't assume it matches English. Keep a personal list of noun pairs where the two languages disagree (conselho, informação, pão, notícia, dinheiro), because those are the ones where you'll make errors. When in doubt, listen for what native speakers actually say: dois conselhos sounds fine in PT, even though "two advices" would sound broken in English.
Common mistakes
❌ Preciso de um pedaço de conselho sobre este problema.
Incorrect — conselho is countable in Portuguese, so it does not take a partitive construction like its English counterpart.
✅ Preciso de um conselho sobre este problema.
I need a piece of advice about this problem.
❌ Quero duas garrafas de águas, por favor.
Incorrect — when using the partitive de, the following mass noun stays singular.
✅ Quero duas garrafas de água, por favor.
I'd like two bottles of water, please.
❌ Há muitos trânsitos na autoestrada esta manhã.
Incorrect — trânsito is a mass noun and does not pluralise to mean 'a lot of traffic'.
✅ Há muito trânsito na autoestrada esta manhã.
There's a lot of traffic on the highway this morning.
❌ Ela tem muitas paciências com as crianças.
Incorrect — paciência is abstract-mass; use the singular with muita.
✅ Ela tem muita paciência com as crianças.
She has a lot of patience with the children.
❌ Comprei três mobiliários novos para a sala.
Incorrect — mobiliário is an uncountable collective and does not pluralise; use peças de mobiliário to count individual pieces.
✅ Comprei três peças de mobiliário novas para a sala.
I bought three new pieces of furniture for the living room.
Key takeaways
- Countable nouns take numerals and pluralise freely; uncountable nouns normally stay singular and need partitive phrases to be quantified.
- Partitives (copo de, fatia de, pedaço de, bocado de) turn mass nouns into countable quantities.
- Mass nouns become countable when context supplies an implicit unit — duas águas in a café, vinhos do Douro (kinds), amores (instances of love).
- Portuguese and English disagree on several key nouns: conselho, informação, pão, notícia are countable in PT where their English counterparts are not.
- Indefinite article with a mass noun almost always signals a specific kind or instance rather than the substance in general.
- Definite article is used for generic reference to mass nouns, where English uses no article (o dinheiro = "money" in general).
