Todos querem liberdade.

Because todos is plural.

• todo = singular, usually every or whole/entire
• todos = plural, usually all or everyone depending on context

In Todos querem liberdade, todos means everyone or all people. Since it refers to more than one person, it has to be plural.

Examples:

• Todo homem erra. = Every man makes mistakes.
• Todos erram. = Everyone makes mistakes.

Because todos is grammatically plural, so the verb must also be plural.

The verb here is querer = to want.

Present tense:

• eu quero
• você/ele/ela quer
• nós queremos
• vocês/eles/elas querem

Since todos matches the idea of they/everyone, Portuguese uses querem.

So:

• Todos querem = Everyone wants / All want

Yes, in this sentence todos is naturally understood as everyone.

Literally, todos is more like all or all people, but in English we often translate it as everyone because that sounds more natural.

So the Portuguese word is plural, but the best English equivalent is often a singular-looking word like everyone.

Portuguese often uses abstract nouns without an article when talking about them in a general sense.

So:

• Todos querem liberdade. = people want freedom in general

If you add the article:

• Todos querem a liberdade.

that can sound more specific, like the freedom, perhaps a particular freedom or a freedom previously mentioned in the conversation.

General idea:

• no article = freedom as a concept
• article = a more specific freedom

Yes, absolutely. Todo mundo quer liberdade is very common in Brazilian Portuguese.

Both are natural, but they feel slightly different:

• Todos querem liberdade. = a bit more direct, neutral, sometimes slightly more formal
• Todo mundo quer liberdade. = very common in everyday speech, often more conversational

Notice the verb change:

• todos is plural → querem
• todo mundo is singular in grammar → quer

So:

• Todos querem...
• Todo mundo quer...

They show gender agreement.

• todos = masculine plural, or mixed groups, or people in general
• todas = feminine plural only

So:

• Todos querem liberdade. = everyone / all people want freedom
• Todas querem liberdade. = all of them want freedom, and the group is female

In Portuguese, the masculine plural is also used for mixed or unspecified groups.

Sometimes yes, but not in this sentence if you want to keep the same meaning.

Portuguese often drops subject pronouns like eu, ele, eles, because the verb ending already gives information. But todos is not just a pronoun here—it adds the idea everyone.

If you say only:

• Querem liberdade.

that means They want freedom, but it does not necessarily mean everyone. The sentence becomes less specific.

So if you want the idea of everyone, keep todos.

In careful Brazilian pronunciation, querem is roughly:

• KEH-rem or KEH-rẽy depending on accent and speaking style

A few notes:

• The qu in querem sounds like k
• The e in the first syllable is like eh
• The final -em in Brazil is often nasal and may sound a bit like ẽy

So many learners hear something close to KEH-rẽy in natural speech.

A rough pronunciation guide is:

TOH-doos KEH-rẽy lee-ber-DAH-jee

A few important details:

• todos: the final s sounds like s in most of Brazil
• liberdade: the final de in Brazilian Portuguese often sounds like jee
• Stress:
  • TO-dos
  • QUE-rem
  • li-ber-DA-de

The strongest stress in the sentence is usually on DA in liberdade.

This word order is the most normal and neutral:

• Todos querem liberdade.

Portuguese word order is fairly flexible, but changing it can sound marked, poetic, or less natural in everyday speech.

For example:

• Liberdade todos querem.

This is understandable, but it sounds more emphatic, as if you are especially focusing on freedom.

So for normal usage, stick with:

• Todos querem liberdade.

Yes, todos can refer to masculine plural nouns in general, not only people.

For example:

• Todos os livros estão aqui. = All the books are here.

But in Todos querem liberdade, because the verb querem implies wanting, the natural interpretation is people. Objects do not normally want things, so listeners understand todos as all people/everyone.

Because Portuguese and English do not use articles in exactly the same way.

With abstract nouns, Portuguese often leaves out the article when speaking generally:

• amor
• paz
• liberdade
• justiça

So:

• Todos querem liberdade. = general statement about freedom as an idea

Adding a makes it more specific or more context-dependent:

• Todos querem a liberdade que lhes foi negada. = Everyone wants the freedom that was denied to them.

So the version without the article is the most natural general statement.
