A2 (Elementary)Lesson 8: Noun Phrase Expansion
Tudo never changes and never takes a noun after it — it is "everything" all by itself: Comi tudo. (I ate everything.) Todo / toda / todos / todas agrees and leans on a noun: todo dia (every day), todas as casas (all the houses). This point separates the two, then shows how one little article turns todo dia (every day) into todo o dia (the whole day).
tudo never changes and never has a noun after it: Comi tudo. (I ate everything.) · Isso é tudo. (That's all.)
todo / toda / todos / todas agrees with the noun beside it: todo dia (every day), todas as casas (all the houses).
The article flips the meaning: todo dia (every day) vs todo o dia (the whole day); toda semana (every week) vs toda a semana (the entire week).
In the plural the article stays: todos os dias (every day), todas as noites (every night).
For "the whole X", Brazilians usually put the noun first: o dia todo (all day), o tempo todo (all the time).
The greetings all run on tudo: Tudo bem? / Tudo bom? / Tudo joia? (How's it going?)
todo mundo means everybody and takes a singular verb: Todo mundo gosta. (Everybody likes it.)
tudo (invariable, stands alone) = everything · todo/toda/todos/todas + noun (agrees) = every, all · todo dia = every day vs todo o dia = the whole day

These two words show up in your first Brazilian hello and never stop: Tudo bem? is the standard greeting and todo dia is how you describe your routine. They are also the pair English speakers scramble most, because English gives both jobs to words built on "all". Saying tudo os dias, or answering Todo bem, marks you as a beginner in one syllable. The article difference is not cosmetic either: tell your boss you worked todo dia when you meant o dia todo and you have promised something quite different.
Both words translate into English words built on "all", which is exactly why they get scrambled. Portuguese keeps them in separate jobs, and one question decides which one you need: does a noun come right after it?
No noun → tudo. It is a pronoun. The thing it refers to is already inside it.
A noun → todo, and it dresses to match: todo, toda, todos, todas (every, all).
| Form | Goes with | Example | Meaning |
|---|---|---|---|
| tudo | nothing — it stands alone | Ele sabe tudo. | He knows everything. |
| todo | masculine singular noun | todo dia | every day |
| toda | feminine singular noun | toda semana | every week |
| Portuguese | Meaning |
|---|---|
| Tudo bem com você? | Is everything OK with you? |
| Eu já terminei tudo. | I've already finished everything. |
| Todo mundo chegou atrasado. | Everybody arrived late. |
| Ela estuda todos os dias. | She studies every day. |
| Nós limpamos a casa toda. | We cleaned the whole house. |
| Toda família tem uma história assim. | Every family has a story like that. |
| Obrigada por tudo! | Thanks for everything! |
| Todas as lojas fecham às sete. | All the shops close at seven. |
Saying tudo os dias. ❌ → ✅ todos os dias (every day). The moment a noun follows, the word has to agree, so it can never be tudo.
Answering Todo bem. ❌ → ✅ Tudo bem. (I'm fine.) There is no noun in the greeting, so it is tudo — and this one is heard immediately.
Putting tudo in front of a noun. ❌ tudo o dinheiro → ✅ todo o dinheiro (all the money). ❌ tudo a comida → ✅ toda a comida (all the food).
Saying tudo mundo. ❌ → ✅ todo mundo (everybody), and keep the verb singular: Todo mundo sabe. (Everybody knows.) ❌ Todo mundo sabem.
Using todo o mundo for "everybody". With the article it means the whole world: ✅ Todo mundo viu o vídeo. (Everybody saw the video.) vs O vídeo rodou o mundo todo. (The video went around the whole world.)
Forgetting agreement in the plural. ❌ todos as casas → ✅ todas as casas (all the houses). Todo matches the noun in gender and number, exactly like any other adjective.
Inventing tudos. Tudo has no plural: ❌ tudos → ✅ tudo (everything) or ✅ todos (all of them).
