What is isso?
isso is a demonstrative pronoun used in Brazilian Portuguese to refer to something that is not here (not close to the speaker) and usually close to the listener or already mentioned. It often translates to English words like that, this (in some contexts), or it when referring to an idea or situation.
Basic position in space and discourse
Use isso when you point to or talk about something that is distant from the speaker or when you refer back to an idea just mentioned. If the object or idea is near the speaker, Portuguese uses este/esta or aqui; if it is far from both speaker and listener, use aquele/aquela.
When to use isso for ideas and situations
There are three common uses of isso when talking about ideas and situations: referring to a previous statement, labeling a general situation, and responding in conversation. Each use has specific patterns and natural examples.
1. Referring back to a previous statement
After someone says something, you can use isso to refer to that content. This is one of the most frequent uses in spoken Portuguese because it makes conversations concise and cohesive.
Example:
Pessoa A: Eu não sei se vou aceitar a oferta de trabalho.
Pessoa B: Entendo. Isso é complicado quando você tem outras prioridades.
Here isso refers to the whole idea previously expressed — the difficulty of deciding about the job offer.
2. Labeling a general situation or fact
You can use isso to point to a general situation, fact, or concept, especially when you want to comment briefly or give an opinion.
Example:
As aulas online têm vantagens, mas isso pode prejudicar a socialização entre alunos.
In this sentence isso refers to the general change or consequence created by online classes.
3. Short answers and reactions
In dialogues, isso is often used as a short reaction word to show agreement or acknowledgement. It functions similarly to English it or that in quick replies.
Example:
— Você gostou do filme?
— Gostei. Isso me surpreendeu.
Here isso points to the surprising element of the film; the speaker gives a compact reaction without repeating the whole idea.
Differences between isso, esse, aquilo, este
Portuguese has several demonstratives that can be confusing. Focus on spatial and discourse relationships to choose the right word.
isso vs esse
isso and esse are related but different parts of speech. Esse is an adjective that modifies a noun (that book, that idea), while isso is a pronoun that replaces a noun or an entire clause.
Examples:
Esse livro é bom. — Esse modifies livro.
Gosto disso. — Isso replaces the idea or object previously mentioned.
isso vs aquilo
Use aquilo when referring to something far from both speaker and listener or to emphasize distance in time or space. Isso usually refers to something near the listener or to a previously mentioned idea in the immediate context.
Examples:
Você lembra do problema que tivemos ano passado?
— Sim, aquilo foi muito difícil. (Referring to a past situation, framed as distant)
— Isso que estamos discutindo agora não é tão grave. (Referring to the current idea)
isso vs este
Este and its forms are used when the referent is close to the speaker or when the speaker introduces new information. For ideas that the speaker is presenting or emphasizing, choose este. For previously mentioned ideas or something near the listener, choose isso.
Examples:
Vou explicar este ponto com calma. (The speaker introduces a point)
Você disse que não quer mais viajar. Isso vem de uma experiência anterior? (Referring to what the listener said)
How isso behaves with verbs and clauses
isso can refer to nouns, verb phrases, clauses, or entire sentences. It is versatile in linking ideas and making conversation flow. When used with verbs of perception, thought, and communication, it often introduces subordinate clauses.
Reporting ideas and opinions
Many verbs accept isso as a neutral object to summarize what someone said or thought. Common verbs include achar, pensar, dizer, concordar, entender.
Examples:
Eu penso que isso não vai funcionar. (Here isso indicates the plan or idea)
Ele disse que isso seria resolvido em uma semana. (Refers to the previous promise)
Using isso with demonstrative adjectives and pronouns
Remember that when you need to modify a noun directly, use esse rather than isso. But to replace a noun phrase or a clause, use isso. This distinction clarifies subject-object relationships in sentences.
Examples:
Eu prefiro esse carro. (Adjective modifying carro)
Prefiro isso. (Pronoun replacing the whole idea or choice)
Common collocations and expressions with isso
Portuguese has common phrases that use isso in idiomatic ways. Learning these will make your speech sound more natural.
Isso mesmo
Use isso with mesmo to express agreement or to confirm something emphatically. It functions like right, exactly, or that’s it in English.
Example:
— Precisamos sair cedo amanhã.
— Isso mesmo.
Isso aí
Isso aí is a colloquial phrase often used to show approval, encouragement, or confirmation — similar to nice, exactly, or you got it.
Example:
— Consegui terminar o relatório.
— Isso aí! Bom trabalho.
Isso quer dizer
Use isso quer dizer to clarify or restate what something means. It is useful when explaining vocabulary, concepts, or consequences.
Example:
A greve foi suspensa, isso quer dizer que as aulas voltam ao normal.
Pronunciation and stress
The word isso is pronounced with two syllables: i-ss-o, where the stress is on the first syllable i. In casual speech, the s sound is pronounced like the English s; in some regions, the initial i can be shorter.
Informal contractions and reductions
In fast spoken Brazilian Portuguese, isso may be reduced slightly, but it is usually clear in conversation. Avoid writing informal contractions in formal contexts.
Practical tips for learners
To master isso, practice by focusing on discourse function rather than translating word-for-word from English. Ask yourself: am I referring back to something already said, labeling a general situation, or answering quickly? If yes, isso is likely correct.
Tip 1: Listen for context
Native speakers use isso frequently in spoken language. Pay attention to when they use it to link ideas or react. This will help you internalize natural patterns faster.
Tip 2: Avoid literal translation traps
English often uses it or that in different ways; Portuguese distinguishes spatial and discourse relationships more clearly. Instead of translating directly, identify whether the referent is near the speaker, near the listener, or distant — then choose between este, isso, and aquilo.
Tip 3: Use set phrases to sound natural
Practice phrases like isso mesmo, isso aí, and isso quer dizer to build conversational fluency. These expressions are common and versatile.
Cultural and usage notes
Brazilian Portuguese relies heavily on context and tone. Using isso appropriately helps you sound natural and polite. In formal writing, you might prefer more explicit nouns or clauses, but in everyday speech, isso keeps conversation fluid.
Register and formality
In very formal texts, writers often avoid pronouns like isso in favor of specific nouns or full clauses to avoid ambiguity. In spoken and informal written Portuguese (messages, emails among friends), isso is perfectly acceptable and common.
Regional variations
Usage of demonstratives can vary slightly by region, but the basic role of isso for referring back to ideas and situations remains consistent across Brazil.
Common mistakes and how to avoid them
Beginners often misuse demonstratives by translating from English. Here are common errors and corrections to help you avoid confusion.
Mistake: Using isso for things close to the speaker
Incorrect:
— Segura isso para mim. (if the object is in the speaker’s hand)
Correct:
— Segura isto para mim. or Segura este para mim.
Explanation: Use isto or este for objects close to the speaker.
Mistake: Replacing nouns with isso when an adjective is needed
Incorrect:
— Quero isso carro.
Correct:
— Quero esse carro.
Explanation: Use esse to modify the noun carro; use isso only to replace the whole idea or noun phrase.
Examples combining multiple uses
Below are longer sample dialogues and sentences that show isso in realistic contexts.
Diálogo 1:
— Você falou que vai mudar de cidade.
— Sim. Isso é verdade, mas ainda não sei quando.
— Entendi. Isso implica muitas decisões, né?
Diálogo 2:
— Precisamos discutir o orçamento.
— Concordo. Isso deve ser prioridade antes do próximo mês.
— Então vamos marcar uma reunião amanhã.
Explanatory sentence:
A crise afetou muitas empresas; isso levou a demissões e mudanças nas estratégias.
Conclusion
Learning to use isso will make your Portuguese more natural when referring to ideas, situations, and previous statements. Focus on the discourse role of isso, practice the common collocations like isso mesmo and isso aí, and pay attention to context to choose among este, isso, and aquilo. With listening and practice, you will quickly gain confidence using isso in everyday Brazilian Portuguese conversations.
