# Ordinal Numbers in Spanish

Just like cardinal numbers, ordinal numbers are adjectives. But, unlike Spanish cardinal numbers, Spanish ordinal numbers actually do match the nouns they modify in both gender and number. Additionally, ordinal numbers usually come before nouns.

Check out these examples showing Spanish ordinal numbers in use.

## Ordinal Numbers: Primero to Décimo

The ordinal numbers from **primero** to **décimo** should be memorized, as they have unique forms and are used to form most of the other ordinal numbers in Spanish.

Here are a list of the ordinal numbers in Spanish from **primero** (*first*) to **décimo** (*tenth*).

English | Spanish |
---|---|

first | |

second | |

third | |

fourth | |

fifth | |

sixth | |

seventh | |

eighth | |

ninth | |

tenth |

## Ordinal Numbers: Decimoprimero to Decimonoveno

The teen ordinal numbers are normally written as a single word, and they are formed according to the following formula.

**décimo** + ordinal number between **primero** and **noveno**

For example:

*thirteenth*: décimo + tercero =**decimotercero***fifteenth*: décimo + quinto =**decimoquinto***seventeenth*: décimo + séptimo =**decimoséptimo**

Note that the accent on **décimo** is removed in these ordinal numbers.

Here are a list of the ordinal numbers in Spanish from **decimoprimero** (*eleventh*) to **decimonoveno** (*nineteenth*).

English | Spanish |
---|---|

eleventh | decimoprimero or undécimo |

twelfth | decimosegundo or duodécimo |

thirteenth | |

fourteenth | |

fifteenth | |

sixteenth | |

seventeenth | |

eighteenth | |

nineteenth |

### Spelling Variations

According to the RAE, it is also acceptable to write the ordinal numbers from **decimoprimero** to **decimonoveno** as two separate words.

For example:

When written as two separate words, both words must agree in gender with any noun they modify. When written as a single word, only the final word in these compounds agrees in gender with the noun.

## Ordinal Numbers Divisible by Ten

Here are a list of the ordinal numbers divisible by 10 that fall between **vigésimo** (*twentieth*) and **nonagésimo** (*ninetieth*). These are used as the base from which to form all the ordinal numbers between *twentieth* and *ninety-ninth*.

twentieth | |

thirtieth | |

fortieth | |

fiftieth | |

sixtieth | |

seventieth | |

eightieth | |

ninetieth |

Using the formula below, forming the ordinal numbers between *twentieth* and *ninety-ninth* is quite easy.

base number (divisible by 10) + ordinal number between **primero** and **noveno**

For example:

*twenty-first*: vigésimo + primero =**vigésimo primero***thirty-sixth*: trigésimo + sexto =**trigésimo sexto***ninety-ninth*: nonagésimo + noveno =**nonagésimo noveno**

## Ordinal Numbers Above 100

Below are the ordinal numbers divisible by 100 that fall between **centésimo** and **milésimo**.

hundredth | |

two hundredth | |

three hundredth | |

four hundredth | |

five hundredth | |

six hundredth | |

seven hundredth | |

eight hundredth | |

nine hundredth | |

thousandth |

For ordinal numbers between 101 and 999, write out each successive ordinal number as a separate word.

For example:

*four hundred eighty-second*:**cuadringentésimo**+**octogésimo**+**segundo**=**cuadringentésimo octogésimo segundo***one hundred seventy-seventh*:**centésimo**+**septuagésimo****séptimo**=**centésimo septuagésimo séptimo**

### Abbreviations

Just like in English, Spanish ordinal numbers are often written in an abbreviated form. To abbreviate Spanish ordinal numbers, you can follow the formulas below.

For masculine ordinal numbers*: numeral +

**.**+ superscript**o**- *For
**primer**and all numbers ending in**primer**= numeral +**.**+ superscript**er** - *For
**tercer**and all numbers ending in**tercer**= numeral +**.**+ superscript**er**

- *For
For feminine ordinal numbers: numeral +

**.**+ superscript**a**

### Placement

In Spanish, ordinal numbers usually go before the nouns they modify. However, if the noun is a member of the royalty, a pope, or a street name, you may see the ordinal adjective come after. For example:

If cardinal and ordinal numbers appear together, the cardinal number goes before the ordinal number. For example:
