The Spanish word todo is extremely common, but translating it is not always straightforward. Depending on the structure, it can mean all, every, the whole, everything, or even completely. It also changes form to agree with masculine, feminine, singular, and plural nouns.

Understanding how to use todo in Spanish means learning which words normally come after it and recognizing the difference between expressions such as todo el día and todos los días. Let’s look at its most important uses.

How to Use Todo in Spanish

The word todo can appear in several different structures depending on whether it refers to a noun, replaces one, or modifies an adjective. To understand how to use todo in Spanish, it is useful to look at each structure separately.

Todo, Toda, Todos and Todas

When todo modifies a noun, it normally agrees with that noun in gender and number:

  • todo + masculine singular
  • toda + feminine singular
  • todos + masculine plural
  • todas + feminine plural

This agreement is one of the first things to remember when learning how to use todo in Spanish.

Todo el equipo trabajó durante varias semanas para terminar el proyecto antes de la fecha prevista.

The whole team worked for several weeks to finish the project before the scheduled date.

Todas las ventanas de nuestra antigua casa daban a un jardín lleno de árboles y flores.

All the windows in our old house looked out onto a garden full of trees and flowers.

Todo el / Toda la: the whole or all the

Use todo el or toda la la before a singular noun when you mean the whole, the entire, or sometimes all the.

Common examples include todo el día (all day), toda la semana (the whole week), and toda la ciudad (the whole city).

Notice that Spanish normally requires the article in expressions such as todo el día. You cannot simply say todo día with the same meaning.

Pasamos todo el día visitando pequeños pueblos de la costa y probando platos típicos de la región.

We spent the whole day visiting small coastal villages and trying typical dishes from the region.

Estuvo lloviendo durante toda la noche, así que decidimos cancelar nuestra excursión a las montañas.

It was raining all night, so we decided to cancel our trip to the mountains.

Todos los / Todas las: all the or every

With plural nouns, use todos los or todas las to mean all the.

Todos los estudiantes de nuestra clase participaron activamente en la actividad que organizó la profesora ayer.

All the students in our class participated actively in the activity that the teacher organized yesterday.

Todas las tiendas del centro cerraron más temprano porque había una importante celebración local aquella tarde.

All the shops downtown closed earlier because there was an important local celebration that afternoon.

With expressions of time, todos los and todas las can also mean every.

  • todos los días (every day)
  • todos los lunes (every Monday)
  • todas las semanas (every week)
  • todos los años (every year)

This contrast is particularly important when studying how to use todo in Spanish:

  • todo el día (all day, the whole day)
  • todos los días (every day)

Mi abuelo sale a caminar todos los días después del desayuno, incluso cuando hace bastante frío afuera.

My grandfather goes for a walk every day after breakfast, even when it is quite cold outside.

Todo el día or todos los días?

One of the most useful distinctions to remember is:

  • todo el día (the whole day, all day)
  • todos los días (every day)

The same contrast can appear with other periods of time:

  • toda la semana (the whole week)
  • todas las semanas (every week)
  • todo el año (the whole year)
  • todos los años (every year)

Once you understand this difference and the basic agreement rules, knowing how to use todo in Spanish becomes much easier.

Todo with possessives and demonstratives

A definite article is not necessary when todo comes before a possessive.

  • toda mi vida (my whole life)
  • todos mis amigos (all my friends)
  • todo nuestro dinero (all our money)

He guardado todos mis apuntes de la universidad porque todavía los consulto cuando necesito recordar ciertos temas.

I have kept all my university notes because I still consult them when I need to remember certain topics.

Vivió toda su vida en aquella pequeña ciudad, aunque viajó con frecuencia por diferentes países europeos.

She lived her whole life in that small city, although she frequently traveled through different European countries.

The same rule applies before demonstratives, so this is how to use todo in Spanish with demonstratives:

  • todo este tiempo (all this time)
  • toda esa información (all that information)
  • todos aquellos problemas (all those problems)

Toda esa información que encontraste en internet puede ayudarnos a preparar mejor nuestra presentación para mañana.

All that information you found online can help us prepare our presentation for tomorrow better.

Todo as a pronoun: everything

Another important point when learning how to use todo in Spanish is that todo can appear without a noun. In this case, singular todo often means everything.

Todo cambió después de aquella conversación, aunque al principio ninguno de nosotros comprendió realmente lo que había ocurrido.

Everything changed after that conversation, although at first none of us really understood what had happened.

Ya he preparado todo para la fiesta, así que solamente tenemos que esperar a que lleguen los invitados.

I have already prepared everything for the party, so we only have to wait for the guests to arrive.

The plural forms todos and todas can also be pronouns meaning everyone, all of them, or they all, depending on the context.

Todos llegaron bastante temprano al restaurante porque querían hablar tranquilamente antes de que comenzara la celebración.

Everyone arrived quite early at the restaurant because they wanted to talk calmly before the celebration began.

Todo lo que: everything that

The expression todo lo que usually means everything that or all that.

Here, lo is a neuter article. It does not refer to a specific masculine noun.

Puedes llevarte todo lo que necesites para terminar el trabajo cómodamente desde tu casa durante el fin de semana.

You can take everything you need to finish the work comfortably from home over the weekend.

This structure is extremely useful in everyday Spanish and is another essential part of understanding how to use todo in Spanish.

Todo lo + adjective

Spanish can also use todo lo + adjective to refer to everything associated with a particular quality.

  • todo lo necesario (everything necessary)
  • todo lo posible (everything possible)
  • todo lo importante (everything important)

Antes de salir de casa, comprobamos todo lo necesario para asegurarnos de que no olvidábamos ningún documento importante.

Before leaving home, we checked everything necessary to make sure that we were not forgetting any important documents.

A related structure, todo lo + adjective + que, can emphasize the degree of a quality:

No imaginas todo lo difícil que resultó encontrar un hotel disponible durante aquel fin de semana tan concurrido.

You cannot imagine how difficult it was to find an available hotel during that very busy weekend.

Todo + singular noun without an article

In more general statements, todo can sometimes appear directly before a singular noun without el or la. In this structure, it generally means every or any.

It is especially common in formal language, rules, definitions, and general statements:

Todo estudiante que quiera participar en el programa deberá presentar su solicitud antes de finalizar el mes.

Every student who wants to participate in the program must submit their application before the end of the month.

Compare:

  • todo estudiante (every student)
  • todos los estudiantes (all the students, every student in a particular group)

This distinction can make how to use todo in Spanish seem complicated at first, but the patterns become predictable with practice.

Todo meaning completely

Todo can sometimes intensify an adjective and have a meaning similar to completely or entirely. In this use, it normally agrees with the person or thing being described.

Después de correr varios kilómetros bajo la lluvia, Marta llegó a casa toda mojada y completamente agotada.

After running several kilometers in the rain, Marta arrived home completely wet and completely exhausted.

El niño se quedó todo sorprendido cuando descubrió que sus amigos habían preparado una fiesta para él.

The boy was completely surprised when he discovered that his friends had prepared a party for him.

You may also encounter the fixed expression del todo, which means completely or entirely:

Todavía no estoy del todo convencido de que cambiar nuestros planes ahora sea realmente la mejor solución.

I am still not completely convinced that changing our plans now is really the best solution.

Unlike todo/toda before an adjective, del todo does not change for gender or number.
