By mastering this topic, you’ll gain a valuable tool for expressing yourself more effectively in Spanish.
Definition of Ordinal Numbers
Ordinal numbers are adjectives that indicate the position or order of something in a series. They answer the question “which one?” as opposed to cardinal numbers, which answer the question “how many?”.
In Spanish, ordinal numbers agree in gender and number with the nouns they modify. This means that the endings of the ordinal numbers change depending on whether the noun is masculine or feminine, singular or plural.
Classification: Ordinal numbers belong to the category of adjectives. They modify nouns by specifying their position in a sequence.
Function: The primary function of ordinal numbers is to denote order or ranking. They provide specific information about the place of an item within a series.
Contexts: Ordinal numbers are used in various contexts, including:
- Dates (e.g., el primero de mayo – the first of May)
- Ranks and positions (e.g., el primer lugar – first place)
- Chapters and sections (e.g., el segundo capítulo – the second chapter)
- Floors of buildings (e.g., el tercer piso – the third floor)
- Lists and sequences (e.g., la quinta persona – the fifth person)
Structural Breakdown
The structure of Spanish ordinal numbers is relatively straightforward, but it’s essential to understand the patterns to form them correctly. Most ordinal numbers are derived from their corresponding cardinal numbers, with specific suffixes added to indicate order.
Formation of Ordinal Numbers
Here’s a general overview of how ordinal numbers are formed from cardinal numbers:
- Primer/Primero and Tercer/Tercero: These are irregular forms used before masculine singular nouns. Primero and tercero shorten to primer and tercer, respectively, when preceding a masculine singular noun.
- -ero/-era: This suffix is commonly added to the cardinal number to form the ordinal number. For example, cuatro (four) becomes cuarto (fourth).
- -ésimo/-ésima: This suffix is used for higher numbers (from eleven onwards). For example, veinte (twenty) becomes vigésimo (twentieth).
Agreement with Gender and Number
Spanish ordinal numbers must agree in gender and number with the nouns they modify. This means the ending of the ordinal number changes depending on whether the noun is masculine or feminine, singular or plural.
For example:
- El primer libro (the first book – masculine singular)
- La primera casa (the first house – feminine singular)
- Los primeros libros (the first books – masculine plural)
- Las primeras casas (the first houses – feminine plural)
Types and Categories of Ordinal Numbers
Spanish ordinal numbers can be categorized based on their formation and usage. Here’s a breakdown of the main types:

Usage Rules for Ordinal Numbers
Proper usage of Spanish ordinal numbers involves several rules, including agreement with gender and number, shortening of primero and tercero, and the correct formation of higher ordinal numbers.
Agreement with Gender and Number
As mentioned earlier, ordinal numbers must agree in gender and number with the nouns they modify. This is a fundamental rule that affects the ending of the ordinal number.
- Masculine Singular: el primer libro (the first book)
- Feminine Singular: la primera casa (the first house)
- Masculine Plural: los primeros libros (the first books)
- Feminine Plural: las primeras casas (the first houses)
Shortening of Primero and Tercero
The ordinal numbers primero and tercero shorten to primer and tercer, respectively, when they precede a masculine singular noun. This shortening does not occur before feminine nouns.
- El primer día (the first day)
- El tercer hombre (the third man)
- La primera semana (the first week) – no shortening
- La tercera oportunidad (the third opportunity) – no shortening
Formation of Higher Ordinal Numbers
For ordinal numbers from eleven onwards, the suffix –ésimo/-ésima is generally added to the corresponding cardinal number. However, there are some variations and less common forms.
- Undécimo/a or Decimoprimero/a (eleventh)
- Duodécimo/a or Decimosegundo/a (twelfth)
- Vigésimo/a (twentieth)
- Trigésimo/a (thirtieth)
Common Mistakes
Learners often make common mistakes when using Spanish ordinal numbers. Being aware of these errors can help you avoid them.
Incorrect Gender Agreement
A frequent mistake is using the wrong gender for the ordinal number. Remember to match the gender of the ordinal number with the noun it modifies.
- Incorrect: El primera libro
- Correct: El primer libro
- Incorrect: La primero casa
- Correct: La primera casa
Not Shortening Primero and Tercero
Forgetting to shorten primero and tercero before masculine singular nouns is another common error.
- Incorrect: El primero día
- Correct: El primer día
- Incorrect: El tercero hombre
- Correct: El tercer hombre
Using Cardinal Numbers Instead of Ordinal Numbers
Using cardinal numbers when ordinal numbers are required can lead to confusion. Make sure to use the correct form to indicate order or position.

Advanced Topics
For advanced learners, there are several nuances and complexities regarding the use of Spanish ordinal numbers.
Alternative Forms
While the –ésimo/-ésima suffix is the standard for higher ordinal numbers, alternative forms exist, particularly for numbers like eleventh and twelfth. These include decimoprimero/a and decimosegundo/a.
Usage in Formal vs. Informal Contexts
In formal writing or speech, the more precise –ésimo/-ésima forms are preferred. In informal contexts, the shorter, basic ordinal numbers are more common.
Historical Usage
Historically, Spanish used ordinal numbers more frequently than it does today. In modern usage, cardinal numbers are often preferred for numbers above ten, except in specific contexts like dates or formal titles.
Frequently Asked Questions (FAQ)
Here are some frequently asked questions about Spanish ordinal numbers:
-
Q: How do I say “first” in Spanish?
A: “First” in Spanish is primero (masculine) or primera (feminine). Before a masculine singular noun, it shortens to primer.
-
Q: When do I use primero vs. primer?
A: Use primer before a masculine singular noun (e.g., el primer día). Use primero in other cases, such as when it stands alone or modifies a masculine noun that is not immediately following (e.g., Él es el primero).
-
Q: How do I form ordinal numbers for numbers higher than ten?
A: Generally, you add the suffix –ésimo/-ésima to the cardinal number (e.g., veinte becomes vigésimo). However, there can be variations and alternative forms.
-
Q: Do ordinal numbers agree in gender and number with the nouns they modify?
A: Yes, ordinal numbers must agree in gender and number. For example, el primer libro (masculine singular) and la primera casa (feminine singular).
-
Q: Can I use cardinal numbers instead of ordinal numbers?
A: In some cases, particularly for numbers above ten, cardinal numbers are acceptable, especially in informal contexts. However, ordinal numbers are more precise and preferred in formal situations.

A: “Twenty-first” in Spanish is vigésimo primero (masculine) or vigésima primera (feminine).
-
Q: Are there any irregular ordinal numbers besides primero and tercero?
A: While primero and tercero are the most common irregular forms due to their shortening, other ordinal numbers may have slight variations in their formation, especially when dealing with higher numbers and compound forms. Always refer to a reliable grammar source for confirmation.
-
Q: Is it common to use ordinal numbers for street addresses in Spanish?
A: No, it is not common to use ordinal numbers for street addresses in Spanish-speaking countries. Cardinal numbers are used instead. For example, you would say “Calle Mayor, número 25” (Main Street, number 25), not “Calle Mayor, número vigésimo quinto.”
