Tudo vs Todo

Tudo vs Todo

If you have been studying Portuguese, you probably came across these two words – tudo and todo. If you did, you probably are wondering when to use tudo and when to use todo. You might even be a bit confused and I don’t blame you.

These two words create a lot of confusion and in this post I will explain to you what is the difference between them.

By the way… I also created a YouTube video about this topic. Check it out here:

How to use Todo

This word means all or every in English, but this probably does not help you much, since tudo is going to have more or less the same translation.

Therefore, I find it more useful to explain how this word is used in Portuguese. Hopefully, you will get it then 🙂

So, the first thing you have to know about todo is that it is variable, unlike tudo. This means that this little word will vary according to the subject of the sentence and it will have masculine, feminine, singular and plural forms.

Take a look:

Masculino SingularFeminino SingularMasculino PluralFeminino Plural

As you can see, when we have a masculine version of this word, it will end in an “o” and in “os” in the plural; on the other hand, when we have a feminine version of this word, we will end up with an “a” at the end of the word in the singular form, and an “as” in the plural form.

But then, when do we use it?

We use it to speak about a whole group of things or people – to speak about all its elements.

Check out the examples below:

Todas as pessoas gostaram do jantar. – Everyone liked the dinner (lit. All the people liked the dinner).

Todos os carros estão estacionados. – All the cars are parked.

As you can see, we use it when we have a group of things or people and we want to include all of the elements of the group in what we are saying – in this case everyone and all the cars.

This means that we had a certain amount of people coming for dinner and from those people everyone liked the dinner. In the same way, imagine we have 100 cars from the guests and we want to say that of those 100 cars, all are parked. We are speaking of all the elements of the group.

Note that todo has to agree with the noun in gender and number – todas as pessoas; todos os carros.

Besides this, I would also like to point out that we can use todo to speak about the whole portion of something.

Let me try to make it clearer.


Imagine you have a cake. A cake is composed of many slices. If someone comes and eats the whole cake, I can say:

Ela comeu o bolo todo.

Note that in this case I can also use todo in a different position on the sentence:

Ele comeu todo o bolo.

So, in this case I am not speaking about the elements of a group, but I am speaking about the whole of something.

Another example could be:

O concerto durou a noite toda.

O concerto durou toda a noite.

They both mean the same and we would translate it as something like The concert was on/took the whole night.

How to use Tudo

Now that we have checked the use of todo, let’s see when we can use tudo.

As I said, tudo can also mean all. However, it can also be translated as everything. This might already help you a little bit telling these two words apart.

In fact, we use tudo to speak about the totality of something and we normally use it to substitute the group of people or things previously mentioned in the text.

Let’s take a look at the following examples:

O Henrique comeu as batatas, o arroz, a carne, o peixe… Comeu tudo! – Henrique ate the potatoes, the rice, the meat, the fish…he ate everything!

Vai tudo ficar bemEverything will be alright.

As you can see, in the last example there is not even a previous reference in the text to the things we are substituting with tudo.

However, we can understand it by context. When we say vai tudo ficar bem (a sentence used often in the times of Covid-19), we mean that everything – be it the people, the jobs, the health, everything… – will be alright. We don’t need to enumerate the things before, we just need to understand what we are talking about by context.

Another point you should pay attention to is that tudo is invariable. That means that it never changes, no matter what noun you have next to it. Tudo will always be tudo.


In conclusion, todo and tudo can be difficult to tell apart, but here are some key points about these two words:


  • It is variable
  • It refers to a whole group of things or people


  • It is invariable
  • It refers to the totality of things
  • It normally substitutes the elements of a group

I hope that this post will help you disentangle these two words and that you will know better when to use one and when to use the other.

Leave me a comment below with a sentence using both tudo and todo. Can you do that? 🙂

  1. Muito obrigado pelo seu artigo Mia! Agora eu entendo melhor a diferença entre as duas palavras.

    Atenciosamente de Berlim,

    1. De nada!
      Ainda bem que pude ajudar!

      1. Tudo do melhor para todos, sempre!!

        1. Olá, Cecilia 🙂
          Obrigada, e igualmente 🙂

  2. Thank you. I got marked wrong on the usage of this in my exercise today, so wanted to get a clearer idea. I did your assessment and got a clear A2, so I don’t want your beginners’ course – but do you do more advanced work? There seems to be an enormous gap after A2 – if I wanted to study more, formally, I’d probably be looking at a course for native speakers in studying classic literature – so a VERY big gap.

    Currently, I’m reading children’s books to try to get through that gap – but I’d like a course!

    1. Olá, Elspeth!
      Yes, I have a course that is more advanced.
      You can check it out here:

      B1-B2 bundle – https://school.learn-portuguese.org/p/b1-b2-course-bundle

      These are the B1 and B2 levels, which can really be good if you are already more advanced.

      I also have some courses to improve your pronunciation even further (although the B1-B2 already covers this as well), which are:

      Speech Course – https://school.learn-portuguese.org/p/speech-course
      Story Time – https://school.learn-portuguese.org/p/interactive-stories-in-portuguese

      I hope this helps.
      Please let me know if you need any further help or if you have any questions.

    1. Olá Andy 🙂
      You are absolutely right. When I was doing the graphic, I wanted to put them the other way round first, and then I decided otherwise but of course forgot to switch them. Thank you for pointing that out. I took it out and will correct it 🙂 Beijinhos, Mia.
