Definition of Spanish Ordinal Numbers
Spanish ordinal numbers indicate the position or order of something in a sequence. Unlike cardinal numbers (uno, dos, tres), which denote quantity, ordinal numbers (primero, segundo, tercero) denote rank. They are adjectives that typically precede the noun they modify, agreeing in gender and number.
Ordinal numbers are essential for expressing concepts such as first, second, third, and so on. They are used in various contexts, including dates, competitions, building levels, and any situation where order or sequence is important. Understanding their formation and usage is vital for clear and accurate communication in Spanish.
Classification and Function
Ordinal numbers function as adjectives, modifying nouns to indicate their position in a series. They agree in gender and number with the noun they modify. For example, el primer libro (the first book, masculine singular) and la primera casa (the first house, feminine singular).
They are classified as determiners because they specify the noun’s position. They differ from cardinal numbers, which simply count or quantify. Ordinal numbers provide information about the order or sequence of items.
Contexts of Use
Ordinal numbers are used in a variety of contexts. Here are some common examples:
- Dates: El primero de enero (The first of January)
- Building Levels: El segundo piso (The second floor)
- Competitions: El tercer lugar (The third place)
- Sequences: La primera vez (The first time)
- Chapters: El capítulo primero (The first chapter)
Structural Breakdown
The structure of Spanish ordinal numbers involves understanding their formation and agreement with nouns. The first ten ordinal numbers have unique forms, while subsequent numbers are generally formed by combining cardinal numbers with suffixes.
Formation of Ordinal Numbers
The ordinal numbers from primero (first) to décimo (tenth) are unique. From eleventh onwards, ordinal numbers are typically formed by adding the suffix -avo to the cardinal number. However, these higher ordinal numbers are less commonly used; instead, cardinal numbers are often used after the tenth.
For example:
- Once (eleven) – Undécimo or Décimo primero (eleventh)
- Doce (twelve) – Duodécimo or Décimo segundo (twelfth)
- Veinte (twenty) – Vigésimo (twentieth)
- Treinta (thirty) – Trigésimo (thirtieth)
Agreement with Nouns
Ordinal numbers must agree in gender and number with the noun they modify. This means that the ordinal number will change its ending to match the noun’s gender (masculine or feminine) and number (singular or plural).
Examples:
- El primer hombre (The first man) – masculine singular
- La primera mujer (The first woman) – feminine singular
- Los primeros hombres (The first men) – masculine plural
- Las primeras mujeres (The first women) – feminine plural
Types and Categories
Spanish ordinal numbers can be categorized based on their position in the sequence (first, second, third, etc.) and their usage in specific contexts. Understanding these categories can help learners use ordinal numbers more effectively.
Basic Ordinal Numbers (1st – 10th)
The first ten ordinal numbers are the most commonly used and have unique forms. These are:
- Primero (first)
- Segundo (second)
- Tercero (third)
- Cuarto (fourth)
- Quinto (fifth)
- Sexto (sixth)
- Séptimo (seventh)
- Octavo (eighth)
- Noveno (ninth)
- Décimo (tenth)
Higher Ordinal Numbers (11th onwards)
Ordinal numbers from eleventh onwards are generally formed by adding the suffix -avo to the cardinal number. However, it’s more common to use cardinal numbers after tenth, especially in everyday speech.
Examples:
- Undécimo or Décimo primero (eleventh)
- Duodécimo or Décimo segundo (twelfth)
- Vigésimo (twentieth)
- Trigésimo (thirtieth)
- Cuadragésimo (fortieth)
- Quincuagésimo (fiftieth)
- Sexagésimo (sixtieth)
- Septuagésimo (seventieth)
- Octogésimo (eightieth)
- Nonagésimo (ninetieth)
- Centésimo (hundredth)
Special Cases
There are some special cases to consider when using ordinal numbers. For example, primero and tercero shorten to primer and tercer respectively when they precede a masculine singular noun.
Examples:
- El primer día (The first day)
- El tercer hombre (The third man)

Usage Rules
Proper usage of Spanish ordinal numbers involves understanding their agreement with nouns, special cases, and the contexts in which they are most appropriate.
Agreement Rules
Ordinal numbers must agree in gender and number with the noun they modify. This is a fundamental rule of Spanish grammar.
- Masculine singular: El primer libro
- Feminine singular: La primera casa
- Masculine plural: Los primeros libros
- Feminine plural: Las primeras casas
Shortening of Primero and Tercero
The ordinal numbers primero and tercero shorten to primer and tercer respectively when they precede a masculine singular noun.
- El primer día (The first day)
- El tercer hombre (The third man)
Cardinal Numbers After Tenth
While ordinal numbers exist for numbers greater than ten, it is more common to use cardinal numbers in everyday speech, especially after tenth.
- Instead of undécimo, you can say décimo primero or simply once.
- Instead of duodécimo, you can say décimo segundo or simply doce.
Common Mistakes
Learners often make common mistakes when using Spanish ordinal numbers. Understanding these mistakes can help you avoid them.
Gender Agreement Mistakes
One common mistake is failing to correctly match the gender of the ordinal number with the noun it modifies.
| Incorrect | Correct | Explanation |
|---|---|---|
| El primera vez | La primera vez | Vez is a feminine noun, so the ordinal number must be feminine. |
| La primer libro | El primer libro | Libro is a masculine noun, so the ordinal number must be masculine. |
Shortening Mistakes
Another common mistake is not shortening primero and tercero when they precede a masculine singular noun.
| Incorrect | Correct | Explanation |
|---|---|---|
| El primero día | El primer día | Primero should be shortened to primer before a masculine singular noun. |
| El tercero hombre | El tercer hombre | Tercero should be shortened to tercer before a masculine singular noun. |
Usage of Higher Ordinal Numbers
Using higher ordinal numbers (beyond tenth) can sound overly formal or unnatural. It’s often better to use cardinal numbers instead.
| Less Common | More Common | Explanation |
|---|---|---|
| El vigésimo primer siglo | El siglo veintiuno | Using the cardinal number is more natural in this context. |
| El trigésimo quinto aniversario | El aniversario treinta y cinco | Using the cardinal number is more natural in this context. |
