“Isso” vs “Isto” in Portuguese: How Brazilians Use These Pronouns

Introduction

Confused about when to use isso versus isto in Brazilian Portuguese? This article explains the difference simply and clearly for English-speaking learners at beginner to intermediate levels. You will see rules, examples, and notes on how native speakers really use these demonstrative pronouns in everyday speech.

What are demonstrative pronouns?

Demonstrative pronouns point to things, ideas, or situations without repeating a noun. In English we use this, that, these, those. In Brazilian Portuguese, several words do the job, including isto, isso, and aquilo. Each has a typical use depending on distance, context, and whether the speaker is introducing or referring back to something.

Basic idea: proximity and reference

Isto, isso, and aquilo form a three-way system of deixis (pointing) in Portuguese. Isto is generally used for something close to the speaker or for something the speaker is about to mention. Isso is used for something close to the listener or for something already mentioned. Aquilo points to something farther away from both speaker and listener. This proximity can be physical or abstract (e.g., an idea).

Rule 1: Use isto for new information or something near the speaker

Isto is the pronoun you use when you present something new or something that is physically or mentally close to you, the speaker. Think of it as the Portuguese equivalent of English this when the speaker emphasizes immediacy or novelty.

Examples:

Eu tenho uma novidade.
Isto vai mudar tudo.

Olha o que eu trouxe:
Isto é para você.

In both examples, isto introduces or highlights something the speaker is offering or presenting. It often appears when the speaker is holding, showing, or starting to explain something.

Rule 2: Use isso for information already introduced or closer to the listener

Isso is used to refer back to something already mentioned, or to indicate something that is nearer to the listener than to the speaker. It functions like English that when referring to previously introduced ideas or objects.

Examples:

Você falou sobre o novo projeto ontem.
Isso me deixou interessado.

Onde está meu celular?
Está ali, sobre a mesa.
Você tá falando de isso?

Here, isso refers to previous conversation content or something the listener is dealing with. It is the most common choice in everyday Brazilian speech when referring back to ideas or objects already in the discourse.

Comparison: introduce vs. refer back

Compare these two short exchanges to see the practical difference:

Eu trouxe um presente.
Isto é para você.
(You are presenting something new directly.)

Você gosta do presente que ganhamos?
Isso foi muito legal.
(You refer back to the present already discussed.)

Rule 3: Physical distance and body language

Physical distance and gestures influence whether Brazilians choose isto or isso. If the speaker is holding or pointing to an object close to them, isto is natural. If the listener holds or is closer to the object, or if the object was mentioned earlier, isso is preferred.

Examples with gestures:

Segure um livro perto de você e diga:
Isto é meu favorito.

Se a outra pessoa está com o livro:
Isso é importante de ler.

Rule 4: Abstract uses — ideas, sentences, and discourse

When pointing to ideas, statements, or parts of a conversation, the same new-versus-old guideline applies. Isto is used to present or highlight an idea just introduced. Isso refers to something the listener already knows or that the conversation has introduced.

Examples:

O que eu quero dizer é o seguinte:
Isto pode demorar algumas semanas.

Você disse que não pode vir hoje.
Isso complica nossos planos.

Note that in everyday Brazilian Portuguese, speakers often use isso when referring to an entire clause or previous statement, especially when summarizing or reacting to what another person said.

Rule 5: When to use aquilo instead

Although the focus is isto and isso, knowing aquilo helps you complete the picture. Aquilo points to something far from both the speaker and the listener, physically or temporally.

Examples:

Lembra daquela casa lá no fim da estrada?
Aquilo parecia abandonado.

Use aquilo when you talk about distant objects, past events far removed from the current conversation, or things neither participant has close access to.

Practical tips: What Brazilians actually say

In natural Brazilian Portuguese, isso is generally more common than isto. Many native speakers use isso in casual speech even in contexts where prescriptive grammar would allow isto. That said, using isto correctly can make your Portuguese sound more precise and formal.

Casual examples:

Você viu o que ela postou?

Minha reação foi:
Isso é demais!

In spoken Portuguese, contractions, intonation, and context often carry the same meaning. So while isto remains correct for immediate, newly introduced items, you will frequently hear isso in everyday conversations.

Tip: Focus on meaning and context, not just rules

If you’re learning, pay attention to whether the speaker is introducing something new or referring back to something. If new and close to you, use isto. If referring back or closer to the listener, use isso. If distant, use aquilo. Over time, your ear will pick up patterns and social usage.

Common phrases and expressions

Here are everyday expressions where isso and isto appear frequently.

Isso é verdade.
Isso não faz sentido.
Isso depende.
Isto é incrível.
Isto é para você.

Notice that isso often appears in idiomatic sets like isso é verdade or isso depende. These phrases are fixed and very common in conversation.

Formal vs informal register

Isto is more common in formal or written Portuguese when presenting examples, definitions, or explanations. Academic writing, formal speeches, and structured texts often favor isto to introduce new content. In contrast, spoken Brazilian Portuguese tends to favor isso, especially in informal contexts.

Examples:

Em um relatório:
Isto demonstra a necessidade de mudanças.

Em uma conversa informal:
Isso foi muito engraçado.

Special cases and exceptions

There are a few special cases to be aware of:

1. Demonstrative + noun: When you place a demonstrative before a noun (this/that + noun), Portuguese uses esse/esta/aquele forms: esse livro, este livro, aquele livro. But when the demonstrative replaces the noun, you use isto, isso, or aquilo.

Example:
Este livro é meu. (this book — before noun)
Isto é interessante. (this is interesting — pronoun)

2. Neutral pronoun isto vs. demonstratives with gender: The pronouns isto, isso, and aquilo are neutral and do not change with gender. When you need gender agreement with a noun, use esse/esta/aquele and their plural forms.

Example:
Você viu aquela casa?
Essa casa é bonita. (a demonstrative adjective agreeing with casa)

3. Colloquial contractions and omissions: In fast speech, Brazilians sometimes drop pronouns or use alternative words like isso mesmo, isso aí, or então to react. These are idiomatic and frequent.

Listening practice: What to expect in real conversations

When listening to Brazilians, expect a high frequency of isso used to react, confirm, or refer back. In TV, podcasts, and casual dialogue, speakers use isso to express agreement, surprise, or dismissal. Meanwhile, presenters, lecturers, and writers will use isto more often when formally introducing concepts or examples.

Sample dialog:

– Eu comprei um carro novo.
– Sério?
– Sim.
– Isso é ótimo!

Sample formal statement:

O autor apresenta dois argumentos.
Isto é essencial para entender a teoria.

Common mistakes and how to avoid them

Beginners often confuse isto and isso because English has only this and that and context differs. To avoid mistakes:

– Ask whether the item or idea is new from the speaker’s perspective. If yes, consider isto.
– Ask whether the item or idea was already mentioned or is closer to the listener. If yes, use isso.
– When in doubt in casual conversation, use isso — native speakers will understand and it sounds natural.
– Pay attention to formal writing and presentations; prefer isto for introduced concepts.

Practice by noticing in media

To internalize the usage, listen to Brazilian podcasts, watch YouTube channels, or read news. Notice when speakers use isto versus isso. Try shadowing sentences aloud to build intuitive sense for proximity and reference. Over time, you will instinctively pick the correct option.

Conclusion

Understanding the difference between isso and isto is mainly about proximity and whether information is new or already mentioned. Use isto for new, immediate information and presentations; use isso for references to earlier comments or things closer to the listener. Remember that isso is very common in spoken Brazilian Portuguese, so when in doubt in casual conversation, isso is usually safe.
