Numbers in Spanish

Quick Answer

Just like in English, Spanish cardinal numbers (números cardinales) can be both nouns and adjectives. But before we get into that, let's learn how to say the numbers in Spanish from 0 to 100 (los números de cero a cien).

Cardinal numbers denote quantity, as opposed to order. To talk about order, you can use ordinal numbers.

Basic Cardinal Number Forms

Here are the numbers from 0 to 20, as well as the multiples of 10 from 10 to 100.

Twenties

The numbers from 21 to 29 use a combination of veinti- and a number from 1-9 (with no space in between).

Note that veintidós, veintitrés, and veintiséis and have an accent on the last syllable.

31-99

Forming the numbers from 31 to 99 is a cinch. You just use a multiple of 10 plus the conjunction y and a number from 1 to 9. Here are some examples.

When to Use Cardinal Numbers

Besides being used to simply count, cardinal numbers are used in Spanish to tell the time and talk about dates and age.

Telling Time

To tell the time in Spanish, you use the verb ser, a feminine definite article (la or las), and a cardinal number.

Son las ocho.
It is eight o'clock.
Es la una de la tarde.
It's one in the afternoon.

Dates

To talk about dates, use the masculine singular definite article (el) and a cardinal number.

To talk about the first of the month, you use the ordinal number primero (first) instead of the cardinal number uno.

Hoy es el diecinueve de mayo.
Today is May 19th.
El primero de enero es mi cumpleaños.
January 1st is my birthday.

Age

To talk about age, use the verb tener and a cardinal number.

Yo tengo veinticuatro años.
I am twenty-four years old.
Mi hermana tiene treinta y nueve años.
My sister is thirty-nine years old.

Cardinal Numbers as Adjectives

As mentioned before, cardinal numbers can be both nouns and adjectives. When a cardinal number is used as an adjective, it doesn't change to match the gender or number of the noun it modifies except in the cases of uno and cien.

Uno

Uno becomes un when used to describe masculine nouns and una when used to describe feminine nouns. Numbers ending in uno (veintiuno, treinta y uno, etc.) also undergo these changes.

Tengo un libro.
I have one book.
Mandé treinta y una cartas.
I sent thirty-one cards.

Cien

Cien changes to ciento in numbers above 100 and changes according to the gender of the noun.

Jorge contó hasta cien.
Jorge counted to a hundred.
Llegaron ciento y diez personas.
One hundred ten people showed up.
Quiero trescientos libros.
I want three hundred books.
Hay doscientas casas en este barrio.
There are two hundred houses in this neighborhood.
