Definition of Noun-Adjective Agreement
Noun-adjective agreement, or concordancia in Spanish, is a grammatical rule that requires adjectives to match the nouns they modify in both gender and number. This means if a noun is masculine and singular, the adjective describing it must also be masculine and singular. Similarly, if a noun is feminine and plural, the adjective must also be feminine and plural. Mastering this agreement is essential for clear and correct communication in Spanish.
The function of noun-adjective agreement is to ensure that sentences are grammatically coherent and easily understood. Without proper agreement, sentences can sound awkward or even convey unintended meanings.
This agreement helps to clarify which noun the adjective is referring to, especially in sentences with multiple nouns.
Noun-adjective agreement is fundamental in all contexts of Spanish, from everyday conversation to formal writing. It is present in simple sentences like “el libro rojo” (the red book) and complex sentences with multiple clauses. Understanding and applying this rule correctly will significantly improve your fluency and accuracy in Spanish.
Structural Breakdown
The structure of noun-adjective agreement in Spanish is based on two key elements: gender and number. Let’s break down each element to understand how they interact.
First, identify the noun. Determine its gender (masculine or feminine) and its number (singular or plural).
Next, choose an adjective that you want to use to describe the noun. The adjective must then be modified to match the gender and number of the noun.
Most adjectives have four possible forms: masculine singular, feminine singular, masculine plural, and feminine plural.
For example, consider the noun “casa” (house), which is feminine and singular. If you want to describe the house as “big,” you would use the feminine singular form of the adjective “grande,” resulting in “la casa grande.” If you were describing multiple houses, “casas” (feminine plural), the correct form would be “las casas grandes.” The adjective changes its form to agree with the noun.
Gender in Spanish
In Spanish, every noun has a gender: either masculine or feminine. Unlike English, where gender is usually associated with biological sex, Spanish assigns gender to all nouns, including inanimate objects and abstract concepts.
This grammatical gender is crucial for noun-adjective agreement.
Masculine Nouns
Masculine nouns typically end in -o, but there are many exceptions. Words ending in -or, -aje, and -ma (of Greek origin) are also often masculine. Additionally, many nouns referring to male people or animals are masculine.
Examples of masculine nouns include: el libro (the book), el chico (the boy), el carro (the car), el profesor (the teacher), el viaje (the trip), and el problema (the problem).
Feminine Nouns
Feminine nouns typically end in -a. Nouns ending in -ción, -sión, -dad, and -tud are also generally feminine. Many nouns referring to female people or animals are feminine.
Examples of feminine nouns include: la casa (the house), la chica (the girl), la mesa (the table), la profesora (the teacher), la canción (the song), and la libertad (the freedom).
Exceptions to Gender Rules
There are several exceptions to the typical gender endings. Some nouns ending in -o are feminine (e.g., la mano – the hand), and some nouns ending in -a are masculine (e.g., el día – the day). These exceptions must be memorized.
Additionally, some nouns have the same form for both masculine and feminine, but their gender is indicated by the article (e.g., el artista – the male artist, la artista – the female artist). Some nouns change meaning depending on their gender (e.g., el capital – the capital (money), la capital – the capital (city)).
Number in Spanish
In Spanish, nouns can be either singular or plural. The number of a noun indicates whether it refers to one item or multiple items.
Adjectives must agree with nouns in number as well as gender.
Singular Nouns
Singular nouns refer to one item. Examples include: el perro (the dog), la flor (the flower), el árbol (the tree), la silla (the chair).
Plural Nouns
To form the plural of most nouns, add -s to nouns ending in a vowel and -es to nouns ending in a consonant. If a noun ends in -z, change the -z to -c and add -es.
Examples of plural nouns include: los perros (the dogs), las flores (the flowers), los árboles (the trees), las sillas (the chairs), los lápices (the pencils), las luces (the lights).
Exceptions to Number Rules
Some nouns do not change in the plural form, especially those ending in -s or -x. The article indicates whether the noun is singular or plural (e.g., el lunes – the Monday, los lunes – the Mondays). Some nouns are only used in the singular or plural form.
Agreement Rules
The fundamental rules for noun-adjective agreement are straightforward, but consistent application is key to mastering Spanish grammar.
Rule One: Gender Agreement
The adjective must match the gender of the noun it modifies. If the noun is masculine, the adjective must be masculine. If the noun is feminine, the adjective must be feminine. For most adjectives ending in -o, change the -o to -a to make it feminine.
Examples:
el libro rojo (the red book) – libro is masculine, so rojo is masculine.
la casa roja (the red house) – casa is feminine, so roja is feminine.
Rule Two: Number Agreement
The adjective must match the number of the noun it modifies. If the noun is singular, the adjective must be singular. If the noun is plural, the adjective must be plural. To make most adjectives plural, add -s if they end in a vowel and -es if they end in a consonant.
Examples:
el libro rojo (the red book) – libro is singular, so rojo is singular.
los libros rojos (the red books) – libros is plural, so rojos is plural.
la casa roja (the red house) – casa is singular, so roja is singular.
las casas rojas (the red houses) – casas is plural, so rojas is plural.
Rule Three: Position of Adjectives
In Spanish, adjectives usually follow the noun they modify. However, some adjectives precede the noun, often to emphasize a quality or express a subjective opinion.
The agreement rules still apply regardless of the adjective’s position.
Examples:
el coche nuevo (the new car) – Adjective follows the noun.
un nuevo coche (a new car) – Adjective precedes the noun (emphasizing “new”).
la hermosa casa (the beautiful house) – Adjective precedes the noun (emphasizing “beautiful”).
la casa hermosa (the beautiful house) – Adjective follows the noun.
Examples of Noun-Adjective Agreement
To further illustrate noun-adjective agreement, let’s examine examples in various forms.

Descriptive Adjectives
Descriptive adjectives specify qualities or characteristics of nouns. They are essential for providing detail and enhancing the clarity of your sentences.
These adjectives must agree in gender and number with the nouns they modify.
Examples of descriptive adjectives include colors (rojo, azul, verde), sizes (grande, pequeño, alto), shapes (redondo, cuadrado), and qualities (inteligente, amable, interesante).
Possessive Adjectives
Possessive adjectives indicate ownership or possession. In Spanish, these adjectives also agree in number (but not gender) with the noun they modify. The possessive adjectives are: mi, tu, su, nuestro/a, vuestro/a, su.
Examples using possessive adjectives: mi libro (my book), nuestra casa (our house), sus amigos (his/her/their friends).
Demonstrative Adjectives
Demonstrative adjectives point out specific nouns. They agree in gender and number with the nouns they modify. The demonstrative adjectives are: este, ese, aquel (and their feminine and plural forms).
Examples using demonstrative adjectives: este libro (this book), esa casa (that house), aquellos árboles (those trees over there).
Usage Rules
Several key rules govern the proper use of noun-adjective agreement in Spanish.
- General Rule: Adjectives must agree in gender and number with the nouns they modify.
- Adjective Placement: Adjectives typically follow the noun, but some can precede it for emphasis.
- Compound Subjects: When an adjective modifies multiple nouns of different genders, the masculine plural form is generally used. If all nouns are feminine, the adjective is feminine plural.
- Adjectives with Fixed Gender: Some adjectives have a fixed gender and do not change form (e.g., inteligente).
- Adjectives That Change Meaning: The meaning of some adjectives changes based on their position relative to the noun (e.g., un hombre pobre – a poor man; un pobre hombre – an unfortunate man).
Exceptions and Special Cases
While the rules of noun-adjective agreement are generally consistent, there are exceptions and special cases to be aware of.
- Nouns with Variable Gender: Some nouns can be either masculine or feminine depending on the context or region (e.g., el mar/la mar – the sea).
- Adjectives with Fixed Forms: Some adjectives have the same form for both masculine and feminine genders (e.g., feliz – happy).
- Adjectives Modifying Infinitives: When an adjective modifies an infinitive, it typically takes the masculine singular form.
- Collective Nouns: Agreement with collective nouns can be tricky and may depend on whether the emphasis is on the group as a whole or the individual members.
Common Mistakes
Many learners make common mistakes when applying noun-adjective agreement. Here are some frequent errors and how to correct them.
| Incorrect | Correct | Explanation |
|---|---|---|
| El casa blanco | La casa blanca | The noun casa is feminine, so the article and adjective must also be feminine. |
| Las libro interesantes | Los libros interesantes | The noun libros is masculine plural, so the article and adjective must also be masculine plural. |
| Un problema grande | Un problema grande | The noun problema is masculine, so the article and adjective must also be masculine. In this case, the original was correct. |
| La chico alto | El chico alto | The noun chico is masculine, so the article and adjective must also be masculine. |
| El mano blanca | La mano blanca | The noun mano is feminine, so the article and adjective must also be feminine. |
| Los dia soleada | Los días soleados | The noun días is masculine plural, so the article and adjective must also be masculine plural. |

Advanced Topics
For advanced learners, understanding more nuanced aspects of noun-adjective agreement can further refine your Spanish skills.
Adjectives with Fixed Gender
Some adjectives have a fixed gender and do not change form to agree with the noun. These adjectives typically end in -e, -ista, or -ante/-ente. While the number must still agree, the gender remains constant.
Examples: un hombre inteligente (an intelligent man), una mujer inteligente (an intelligent woman), los hombres inteligentes (the intelligent men), las mujeres inteligentes (the intelligent women).
Adjectives That Change Meaning Based on Position
The meaning of some adjectives changes depending on whether they precede or follow the noun. Understanding these nuances is crucial for accurate communication.
Examples:
- un hombre pobre (a poor man – lacking money) vs. un pobre hombre (an unfortunate man – evokes pity)
- una casa grande (a big house – refers to size) vs. una gran casa (a great house – refers to quality or importance)
- un amigo viejo (an old friend – refers to age) vs. un viejo amigo (a long-time friend – refers to the duration of the friendship)
Frequently Asked Questions
Why is noun-adjective agreement important in Spanish?
Noun-adjective agreement is crucial for grammatical correctness and clarity. It ensures that your sentences are easily understood and avoids confusion.
Without proper agreement, sentences can sound awkward or convey unintended meanings.
What if an adjective modifies multiple nouns of different genders?
When an adjective modifies multiple nouns of different genders, the masculine plural form is generally used. If all nouns are feminine, the adjective is feminine plural.
