“Aquilo” vs “Isso” in Portuguese: Pointing to Ideas and Situations

Introduction

Understanding demonstratives is essential for clear Portuguese communication. Two commonly confusing words are aquilo and isso. Both point to ideas, actions, or situations rather than concrete objects, but they signal different distances in conversation and different relationships to what was said. This article explains when to use each word, with examples and cultural notes.

What are demonstrative pronouns for ideas?

In Portuguese, demonstrative pronouns like aquilo and isso can refer to physical things or to concepts, statements, actions, and situations. When they point to ideas rather than objects, they function similarly to English words such as that, that idea, or that thing you said.

Both aquilo and isso are neutral forms used to refer to non-gendered, abstract content. They do not change for gender or number when used as neutral pronouns pointing to ideas.

Basic difference: distance in discourse

The easiest rule to remember is that isso usually refers to something close in the conversation — what was just said or what the listener knows — while aquilo points to something farther away — what was said earlier, something less immediate, or something outside the shared context.

Think of distance not as physical but as conversational proximity. Isso = near in the dialogue. Aquilo = farther in the dialogue or outside the immediate exchange.

Examples showing conversational proximity

When someone repeats or reacts to a statement just made by the other person, use isso.

Maria: Eu acho que ele não vai vir hoje.
João: Por que você acha isso?

Here isso refers to Maria’s immediate assertion. It feels close because the comment was just made.

Now an example with aquilo. Imagine referring to something mentioned much earlier or by someone else previously.

Ana: Lembra daquela reunião na semana passada?
Pedro: Sim, não gostei muito daquilo.

Here aquilo refers back to the earlier meeting — a bit more distant in the conversation.

When both are possible: subtle differences

In some sentences both isso and aquilo can be used, but the nuance changes. Choosing one paints a different relationship to the referenced idea.

Example with both options:

Você ouviu o comentário do chefe?
Resposta A: Eu não gostei disso.
Resposta B: Eu não gostei daquilo.

Resposta A (disso) suggests the comment was just made or is being discussed right now. Resposta B (daquilo) can suggest more distance, a detached judgment, or that the speaker refers to a past event or to something previously reported.

Using isso and aquilo to react to new information

When someone tells you something and you react immediately, Brazilians commonly use isso. It signals engagement with the just-heard information.

Example:

Amiga: Vou mudar de emprego na próxima semana.
Você: Sério? E por que isso?

By asking por que isso you show direct curiosity about the freshly revealed situation.

Using aquilo to summarize or distance

Aquilo often appears when summarizing an entire situation, when forming an opinion about events not currently being narrated, or when the speaker creates distance (emotional or temporal).

Example of summarizing:

Depois de ouvir todas as histórias, ele disse que não concordava com aquilo.
Here aquilo encapsulates the entire set of stories or facts already presented.

Example of distancing:

Ouvi o que aconteceu com eles, mas prefiro não me envolver com aquilo.
Using aquilo expresses detachment.

Pointing to ideas that are not spoken aloud

Both isso and aquilo can refer to implicit or unspoken ideas, but again the distance rule applies. If the idea is implicit but part of the immediate exchange, use isso. If it is inferred from previous context or by third parties, use aquilo.

Example:

Você percebeu a tensão entre eles?
Percebi isso, mas tentei não comentar.
Aqui, isso refers to the tension just observed in the moment.

Agora:

Ele contou o rumor ontem. Não quero me envolver com aquilo.
Here aquilo refers to the rumor mentioned earlier, indirectly.

Pronominal combinations and prepositions

When combined with prepositions, both words follow normal Portuguese grammar. Observe forms like com isso, com aquilo, sobre isso, sobre aquilo.

Examples:

Concordo com isso.
Não quero falar sobre aquilo agora.

Note that when these words are the object of a preposition, they behave like neutral pronouns and do not change gender or number. However, there are related demonstrative adjectives like este/essa/aquele that do change and modify nouns. Those are separate but related topics.

Distinguishing from este/essa/aquela and demonstrative adjectives

It helps to contrast isso and aquilo with demonstrative adjectives. Words like este, esse, aquele (and their feminine forms esta, essa, aquela) modify nouns. By contrast, isso and aquilo are neutral pronouns standing alone to refer to ideas or unspecified things.

Example:

Este livro é meu. Isso é importante.
Este modifies livro; isso stands alone and refers to the idea of importance.

Understanding this difference prevents errors like trying to use isso directly before a noun. For a noun you would pick esse/aquele depending on proximity (essa ideia, aquela situação).

Regional and colloquial usage notes

In Brazilian Portuguese, conversational use often favors isso when reacting immediately and aquilo when distancing. However, real speech can be flexible. Tone, emphasis, and gestures can change meaning. In informal contexts, people may use isso even for earlier events if they want to bring the topic back into the immediate conversation.

Also, some speakers use isso broadly for everything close to the listener and aqui/ali/aí to mark physical space: aqui (here), aí (there, near listener), ali/lá (there, farther away). These spatial demonstratives interact with the neutral pronouns: for ideas, use isso (near in discourse) and aquilo (farther in discourse).

Common mistakes and how to avoid them

Mistake 1: Using aquilo when reacting to something just said. This can make the response sound detached or like the speaker is referring to a different moment. To avoid it, ask yourself whether the idea is immediate: if yes, choose isso.

Mistake 2: Trying to use isso directly before a noun. Remember that isso is a neutral pronoun and does not modify nouns. Use esse/essa/esses if you need an adjective before a noun.

Mistake 3: Overgeneralizing physical distance. Always consider conversational distance and ownership of the information. Is the idea owned by the speaker, the listener, or a third party? Use that as a clue: owned by the listener or just mentioned = isso; by a third party or earlier mention = aquilo.

Practical phrases and patterns to memorize

These short, useful patterns help internalize usage.

Por que você disse isso? — Why did you say that (just said)?
Não gostei daquilo que ele falou. — I did not like what he said (earlier or third-party comment).
Concordo com isso. — I agree with that (the immediate point).
Prefiro não comentar sobre aquilo. — I prefer not to comment about that (the broader situation).

Translation tips: matching English that/that thing

When translating from English, pay attention to whether English that refers to an immediate comment or a more remote idea. Both isso and aquilo usually translate to that in English, so choose based on conversational distance rather than literal matching.

English example: I don’t like that.
Possible Portuguese translations: Não gosto disso or Não gosto daquilo.
Pick disso if reacting to something just said; pick daquilo if referring to a past action or distant situation.

Subtle emotional shading with aquilo

Aquilo can add a tone of judgment, finality, or detachment. When you hear a native speaker use aquilo, they may be signaling that they consider the referred idea settled, problematic, or not part of the immediate conversation anymore.

Example:

Depois de tudo, eu não quero saber mais daquilo.
The speaker is closing the topic and distancing emotionally.

Quick checklist for choosing between isso and aquilo

1. Was the idea just mentioned by the speaker or listener? If yes, choose isso.
2. Is the idea from earlier in the conversation or from a third party? If yes, choose aquilo.
3. Do you want to show involvement or detachment? Use isso for involvement, aquilo for detachment.
4. Are you modifying a noun? Then use esse/essa/aquele instead of isso or aquilo.

Real dialogue examples

Example 1 — immediate reaction:
Paula: Eu perdi o emprego hoje.
Lucas: Sério? O que aconteceu para você perder isso?

Example 2 — referring back to an earlier event:
Evento: Alguém espalhou boatos na festa ontem.
Depois: Eu ouvi sobre aquilo hoje de manhã.

Example 3 — emotional distance:
Conversa: Eles brigaram e falaram coisas duras.
Resposta: Não quero mais lidar com aquilo.

Final usage tips

Listen to native speakers and pay attention to how they place isso and aquilo in conversation. When practicing, try substituting one for the other and notice how the nuance changes. Over time, the feeling of conversational distance will become intuitive, and choosing the correct form will feel natural.

Conclusion

Learning the difference between aquilo and isso helps you become more precise and natural in Portuguese. Remember that the key is conversational distance and relationship to the idea: isso for immediate or listener-linked ideas, aquilo for earlier, more distant, or emotionally detached references. With exposure and practice, these choices will become intuitive.
