Todos querem liberdade.

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

• ele/ela quer = he/she wants
• eles/elas querem = they want

Here, todos means everyone / all people, so Portuguese uses the 3rd person plural form: querem.

In this sentence, todos means everyone or all people.

Literally, todos is the masculine plural form of all. Portuguese often uses the masculine plural for a mixed group or for people in general.

So Todos querem liberdade is a natural way to say Everyone wants freedom.

Todos is the masculine plural form, and in Portuguese it is also the default plural for a mixed or unspecified group.

If you were talking only about women, you would say:

• Todas querem liberdade.

So:

• todos = all/everyone, masculine or mixed group
• todas = all, feminine group

Portuguese often omits subject pronouns because the verb ending already shows who the subject is.

In querem, the ending -em tells you it is they / you plural / formal plural. Since the subject todos is already present, there is no need to add eles.

You could say Todos eles querem liberdade, but that is usually unnecessary and sounds more emphatic.

Because abstract nouns like liberdade, paz, amor, and justiça often appear without an article when speaking in a general sense.

So:

• querem liberdade = want freedom
• querem a liberdade = want the freedom

The version without the article is more general and natural here.

Yes. Todos can stand alone when the noun is understood.

For example:

• Todos querem liberdade. = Everyone wants freedom.
• Todos chegaram. = Everyone arrived.

You could also say Todas as pessoas querem liberdade, but todos is shorter and more natural in many contexts.

The normal word order is:

• Todos querem liberdade.

This is the most neutral and natural order.

You could change the order for style or emphasis in some contexts, but that would be less neutral. For a learner, it is best to stick with:

• subject + verb + object

So: Todos + querem + liberdade

In European Portuguese, the pronunciation is approximately:

TOH-doosh KEH-rem lee-ber-dah-d(ə)

A more IPA-like version is roughly:

/ˈto.duʃ ˈkɛ.ɾɐ̃j̃ li.bɨɾˈða.dɨ/

A few useful points:

• todos often sounds like todush
• querem has a nasal ending in European Portuguese
• unstressed vowels are often reduced in Portugal
• liberdade does not sound exactly like the English word liberty

Yes, absolutely. Toda a gente quer liberdade is very common in European Portuguese and means the same thing: Everyone wants freedom.

Compare:

• Todos querem liberdade.
• Toda a gente quer liberdade.

Both are correct.
Toda a gente is often very natural in everyday speech.
Grammatically, toda a gente is singular, so it takes quer, not querem.

The dictionary form is querer, which means to want.

Here is part of the present tense:

• eu quero = I want
• tu queres = you want
• ele/ela quer = he/she wants
• nós queremos = we want
• vocês querem = you want
• eles/elas querem = they want

So querem is the present-tense form of querer used with a plural subject.

Usually yes, but the exact nuance depends on context.

Liberdade can mean:

• freedom in a broad, general sense
• liberty, especially in political or legal contexts
• personal freedom or independence

In this sentence, liberdade is a general abstract noun, so freedom is the most natural translation.
