Definition of Spanish Ordinal Numbers
Ordinal numbers in Spanish, known as números ordinales, indicate the position or order of something in a sequence. They are used to specify which item is first, second, third, and so on. Unlike cardinal numbers, which simply count, ordinal numbers denote rank or order. Understanding and using ordinal numbers correctly is essential for clear and accurate communication in Spanish.
Ordinal numbers function as adjectives, meaning they modify nouns. They agree in gender and number with the nouns they modify.
For example, if you are referring to “the first girl,” you would use the feminine singular form of the ordinal number. Ordinal numbers are commonly used in dates, competitions, and when describing a series of events or items.
They are classified as determiners, specifically ordinal determiners, as they specify the position of a noun in a sequence. Their function is to provide order and ranking within a set of items or events.
Ordinal numbers are used in a wide range of contexts, from everyday conversations to formal writing, making them an indispensable part of Spanish grammar.
Structural Breakdown
The structure of Spanish ordinal numbers is generally straightforward. The first ten ordinal numbers have unique forms, while the rest are typically formed by adding suffixes to the cardinal numbers.
Understanding these patterns is key to mastering ordinal number formation. The suffixes added to cardinal numbers to transform them into ordinal numbers are usually ‘-ésimo’ for masculine and ‘-ésima’ for feminine forms.
For numbers ending in ‘-o’ (like uno), the ‘-o’ is dropped before adding the suffix (e.g., primer instead of unoésimo). For numbers ending in consonants, the suffix is added directly (e.g., catorce becomes décimo cuarto). These are usually used for numbers above tenth.
Understanding the gender and number agreement is critical. Ordinal numbers must agree with the noun they modify. For masculine nouns, use the masculine form (e.g., el primer libro – the first book). For feminine nouns, use the feminine form (e.g., la primera casa – the first house). The same applies to plural nouns (e.g., los primeros libros – the first books, las primeras casas – the first houses).
Types or Categories of Ordinal Numbers
Basic Ordinal Numbers (1st – 10th)
The first ten ordinal numbers are unique and must be memorized. They form the foundation for understanding more complex ordinal numbers.
These are frequently used in everyday language and are essential for basic communication.
Compound Ordinal Numbers (11th and beyond)
Ordinal numbers from eleventh onwards are often formed using a combination of décimo (tenth) and the corresponding cardinal number. For example, undécimo (eleventh) can also be expressed as décimo primero. Understanding this pattern simplifies the formation of higher ordinal numbers.
Shortened Forms of First and Third
The ordinal numbers primero (first) and tercero (third) have shortened forms: primer and tercer. These shortened forms are used before masculine singular nouns. For example, you would say el primer día (the first day) instead of el primero día.
Ordinal Numbers in Dates
In Spanish, ordinal numbers are used to indicate the first day of the month. For example, el primero de mayo (the first of May). For all other days, cardinal numbers are used. This is a specific usage rule that is important to remember when writing or speaking about dates.

Usage Rules
Gender and Number Agreement
Ordinal numbers must agree in gender and number with the nouns they modify. This is a fundamental rule that applies to all adjectives in Spanish.
For masculine singular nouns, use the masculine singular form of the ordinal number. For feminine singular nouns, use the feminine singular form.
The same principle applies to plural nouns.
Shortened Forms: Primer and Tercer
Remember that primero (first) and tercero (third) are shortened to primer and tercer when they precede a masculine singular noun. This is a common rule that can be easily overlooked. For example, “the first day” is el primer día, not el primero día.
Ordinal Numbers in Dates
Use ordinal numbers only for the first day of the month. For all other days, use cardinal numbers. For example, “the first of January” is el primero de enero, but “the second of January” is el dos de enero.
Compound Ordinal Numbers
For compound ordinal numbers (11th and beyond), you can use either the combined form (e.g., undécimo) or the separated form (e.g., décimo primero). Both forms are generally acceptable, but the combined form is more common for numbers up to 20th.
Placement of Ordinal Numbers
Ordinal numbers typically precede the noun they modify, similar to adjectives in Spanish. For example, la primera casa (the first house), el segundo libro (the second book).
Common Mistakes
Incorrect Gender Agreement
Incorrect: El primera casa
Correct: La primera casa (The first house)
Explanation: The ordinal number must agree in gender with the noun. Casa is feminine, so the ordinal number must be primera.
Not Shortening Primero and Tercero
Incorrect: El primero día
Correct: El primer día (The first day)
Explanation: Primero should be shortened to primer before a masculine singular noun.
Using Ordinal Numbers for All Dates
Incorrect: El primero de mayo, el segundo de mayo
Correct: El primero de mayo, el dos de mayo (The first of May, the second of May)
Explanation: Ordinal numbers are used only for the first day of the month. Cardinal numbers are used for all other days.
Incorrect Word Order
Incorrect: Casa la primera
Correct: La primera casa (The first house)
Explanation: Ordinal numbers usually precede the noun they modify.
Mixing Cardinal and Ordinal Numbers
Incorrect: El dos libro
Correct: El segundo libro (The second book)
Explanation: Ensure you’re using ordinal numbers when you mean to indicate order or position, not quantity.

Advanced Topics
Complex Ordinal Numbers
Ordinal numbers beyond 100 follow a similar pattern to numbers between 20 and 100. You combine the appropriate ordinal form of the hundreds with the cardinal or ordinal numbers for the tens and units. For example: centésimo primero (101st), ducentésimo vigésimo quinto (225th), milésimo quincuagésimo (1050th).
Figurative Usage
Ordinal numbers can also be used figuratively to express importance or significance. For example, Es de primera (It’s first-rate) or Es un problema de primer orden (It’s a problem of the first order).
Literary and Historical Contexts
In literature and historical texts, you might encounter more archaic or elaborate forms of ordinal numbers. These forms are less common in everyday speech but understanding them can enhance your comprehension of older texts. For example, in historical contexts, ordinal numbers might be used to refer to monarchs or historical figures (e.g., Carlos Quinto – Charles the Fifth).
Regional Variations
While the basic rules for ordinal numbers are consistent across Spanish-speaking regions, there might be slight variations in usage or preference. Being aware of these regional differences can help you better understand and communicate with speakers from different countries.
FAQ
- What is the difference between cardinal and ordinal numbers?
Cardinal numbers are used for counting (one, two, three), while ordinal numbers indicate order or position (first, second, third). Cardinal numbers answer the question “how many?”, whereas ordinal numbers answer the question “which one?”.
- How do I form ordinal numbers from 11th to 20th?
You can use either the combined form (e.g., undécimo, duodécimo) or the separated form (e.g., décimo primero, décimo segundo). Both are generally acceptable, but the combined form is more common, especially up to the 15th.
- When do I use the shortened forms primer and tercer?
Use primer instead of primero and tercer instead of tercero when they precede a masculine singular noun. For example, el primer día (the first day), el tercer hombre (the third man).
- Are ordinal numbers used for all dates in Spanish?
No, ordinal numbers are only used for the first day of the month (el primero de mayo). For all other days, use cardinal numbers (el dos de mayo).
- Do ordinal numbers agree in gender and number with the nouns they modify?
Yes, ordinal numbers must agree in gender and number with the nouns they modify. Use the masculine form for masculine nouns and the feminine form for feminine nouns. The same applies to plural nouns.
- How do I form ordinal numbers beyond 20th?
Combine the ordinal form of the tens with the cardinal number for the units. For example, vigésimo primero (21st), trigésimo segundo (32nd).
- Can ordinal numbers be used figuratively?
Yes, ordinal numbers can be used figuratively to express importance or significance. For example, Es de primera (It’s first-rate).
