Definition of Ordinal Numbers in Spanish
Ordinal numbers in Spanish, like in English, indicate the position or order of something in a sequence. They answer the question “which one?” instead of “how many?” They are adjectives that typically precede the noun they modify, agreeing in gender and number.
Understanding ordinal numbers is essential for describing rankings, dates, and various other scenarios where order matters.
While cardinal numbers (uno, dos, tres) represent quantity, ordinal numbers (primero, segundo, tercero) denote position. For example, “tres libros” means “three books,” while “el tercer libro” means “the third book.” The distinction is crucial for clear and accurate communication.
Ordinal numbers function as adjectives, modifying nouns to specify their position in a sequence. They must agree in gender (masculine or feminine) and number (singular or plural) with the noun they modify. For instance, “el primer día” (the first day) uses the masculine singular form of the ordinal number, while “la primera semana” (the first week) uses the feminine singular form.
Ordinal numbers are used in a wide range of contexts, including: describing positions in a race or competition, indicating floors in a building, numbering chapters in a book, specifying dates, and referring to academic grades or years. They are fundamental for expressing order and sequence in many aspects of daily life.
Structural Breakdown
The structure of Spanish ordinal numbers is relatively straightforward, especially from primero (first) to décimo (tenth). Beyond tenth, the formation often involves using the cardinal number followed by the word “-ésimo”. However, there are some important details to consider.
Ordinal numbers from first to tenth have specific unique forms: primero, segundo, tercero, cuarto, quinto, sexto, séptimo, octavo, noveno, décimo. These are the most commonly used ordinal numbers, and it’s essential to memorize them.
From eleventh onwards, the ordinal numbers are generally formed by adding the suffix “-ésimo” to the cardinal number. For example, “once” (eleven) becomes “undécimo” (eleventh), and “doce” (twelve) becomes “duodécimo” (twelfth). While these forms exist, they are less commonly used in everyday speech. Instead, speakers often use cardinal numbers after tenth in many contexts.
Ordinal numbers must agree in gender and number with the noun they modify. Masculine singular forms like “primer” are used before masculine singular nouns, while feminine singular forms like “primera” are used before feminine singular nouns. Plural forms (primeros, primeras) are used with plural nouns. This agreement is critical for grammatical correctness.
There are some shortening rules for primero and tercero. When these ordinal numbers precede a masculine singular noun, they are shortened to primer and tercer, respectively. For example, “el primer libro” (the first book) and “el tercer piso” (the third floor). This shortening does not occur before feminine nouns.
Types and Categories of Ordinal Numbers
Spanish ordinal numbers can be categorized based on their form and usage. The most common categories are basic ordinal numbers (first to tenth) and those formed with the “-ésimo” suffix. Understanding these categories helps clarify their application.
Basic Ordinal Numbers (1st – 10th)
These are the most frequently used ordinal numbers and have unique forms. They are essential for everyday conversations and should be memorized. They have masculine and feminine forms, singular and plural forms, and are used in a variety of contexts. For example, primero/primera, segundo/segunda, tercero/tercera, cuarto/cuarta, quinto/quinta, sexto/sexta, séptimo/séptima, octavo/octava, noveno/novena, décimo/décima.
“-ésimo” Formed Ordinal Numbers (11th and beyond)
These ordinal numbers are formed by adding the suffix “-ésimo” to the cardinal number. While grammatically correct, they are less commonly used in spoken Spanish, especially for higher numbers. In many cases, cardinal numbers are used instead. Examples include: undécimo/undécima, duodécimo/duodécima, decimotercero/decimotercera.
Shortened Forms
The ordinal numbers primero and tercero have shortened forms (primer and tercer) that are used before masculine singular nouns. This is a common feature of Spanish grammar and must be remembered to avoid errors. Examples: el primer día, el tercer acto.
Compound Ordinal Numbers
Compound ordinal numbers are used for numbers greater than ten, and they can be complex. These are rarely used in common speech; instead, people use cardinal numbers after the tenth. An example is vigésimo primero (twenty-first), although you’d more commonly hear veintiuno in many contexts.

Usage Rules for Ordinal Numbers
Using ordinal numbers correctly involves understanding their agreement with nouns, the shortening of certain forms, and the preference for cardinal numbers in certain contexts. Adhering to these rules will ensure clarity and accuracy in your Spanish communication.
Ordinal numbers must agree in gender and number with the noun they modify. Use the masculine form (primero, segundo) with masculine nouns and the feminine form (primera, segunda) with feminine nouns. Similarly, use the singular form with singular nouns and the plural form with plural nouns. For example: el primer libro (the first book), la primera casa (the first house), los primeros libros (the first books), las primeras casas (the first houses).
Remember that primero and tercero are shortened to primer and tercer, respectively, when they precede a masculine singular noun. This rule applies only when the ordinal number directly precedes the noun without any intervening words. For example: el primer día (the first day), el tercer piso (the third floor). The full forms primero and tercero are used before feminine nouns and when they do not directly precede the noun. For example la primera semana (the first week), el número tercero (the number three).
While ordinal numbers can be formed for numbers beyond tenth by adding the “-ésimo” suffix, it is more common to use cardinal numbers in everyday speech. This is especially true for higher numbers. For example, instead of saying “el vigésimo quinto aniversario” (the twenty-fifth anniversary), it is more common to say “el aniversario veinticinco.”
When writing dates, the first day of the month is expressed using the ordinal number primero. For example, “el primero de mayo” (the first of May). For all other days of the month, cardinal numbers are used. For example, “el dos de junio” (the second of June), “el quince de septiembre” (the fifteenth of September).
Common Mistakes with Ordinal Numbers
Even experienced Spanish learners can make mistakes with ordinal numbers. Recognizing these common errors and understanding how to correct them will help you improve your accuracy and fluency.
One of the most common mistakes is failing to agree the ordinal number with the noun in gender and number. For example, saying “el primera casa” instead of “la primera casa” is incorrect. Always ensure that the ordinal number matches the gender and number of the noun it modifies.
Another common error is forgetting to shorten primero and tercero to primer and tercer before masculine singular nouns. For example, saying “el primero día” instead of “el primer día” is a mistake. Remember to apply this shortening rule whenever applicable.
Overusing “-ésimo” forms for numbers beyond tenth can sound unnatural. While grammatically correct, it is often better to use cardinal numbers in everyday speech. For example, saying “el decimocuarto libro” can be replaced with the more natural “el libro catorce.”
Using ordinal numbers for all dates is incorrect. Only the first day of the month is expressed with an ordinal number. All other days are expressed with cardinal numbers. For example, saying “el segundo de marzo” instead of “el dos de marzo” is a common mistake.
Here are some examples of common mistakes and their corrections:
| Incorrect | Correct | Explanation |
|---|---|---|
| El primera libro | El primer libro | Agreement error: “primera” (feminine) should be “primer” (masculine shortened form) before a masculine singular noun. |
| La primero casa | La primera casa | Agreement error: “primero” (masculine) should be “primera” (feminine) to agree with “casa” (feminine). |
| El decimosegundo día | El duodécimo día / El día doce | While “decimosegundo” is grammatically correct, “duodécimo” or “el día doce” are more natural. |
| El segundo de mayo (referring to May 1st) | El primero de mayo | Only the first day of the month uses an ordinal number. |

Advanced Topics
For advanced learners, understanding the nuances of ordinal number usage and their historical evolution can provide a deeper appreciation of the Spanish language.
While the “-ésimo” suffix is the standard way to form ordinal numbers beyond tenth, there are archaic forms that are occasionally encountered in literature or formal contexts. These forms, such as “onceno” (eleventh) and “doceno” (twelfth), are rarely used in modern Spanish but are worth recognizing.
The usage of ordinal numbers has evolved over time, with a gradual shift towards using cardinal numbers in many contexts. This trend reflects a simplification of the language and a preference for more concise expressions.
Understanding this historical context can help you appreciate the flexibility and adaptability of Spanish.
In some Latin American countries, there may be slight variations in the usage or preference for certain ordinal number forms. Being aware of these regional differences can help you communicate more effectively with speakers from different Spanish-speaking regions.
The Real Academia Española (RAE), the official institution responsible for regulating the Spanish language, provides guidelines and recommendations on the proper usage of ordinal numbers. Consulting the RAE’s publications can offer valuable insights into the nuances of Spanish grammar and usage.
Frequently Asked Questions
