Noun-adjective agreement is a fundamental rule in Spanish grammar. Adjectives must match the gender and number of the nouns they modify. This means that if the noun is feminine and plural, the adjective must also be feminine and plural, and so on.

Gender Agreement

Adjectives change form depending on whether the noun is masculine or feminine.
  • Masculine nouns: Adjectives usually end in -o.
  • Feminine nouns: Adjectives usually end in -a.
  • Adjectives ending in -e or a consonant remain the same for both genders.

Examples

Noun (Spanish)Adjective (Spanish)Noun + Adjective (Spanish)Noun + Adjective (English)
el libroblancoel libro blancothe white book
la mesablancala mesa blancathe white table
el cochegrandeel coche grandethe big car
la casagrandela casa grandethe big house

Translate: 'The white (blanco) _____' with a masculine noun.


el libro blanco

'Libro' is masculine singular, so the adjective remains 'blanco' to match gender.

Number Agreement

Adjectives must also agree with the singular or plural form of the noun.
  • Singular nouns: Adjectives remain in their base form.
  • Plural nouns: Add -s if the adjective ends in a vowel, -es if it ends in a consonant.

Examples

Noun (Spanish)Adjective (Spanish)Noun + Adjective (Spanish)Noun + Adjective (English)
el gatonegroel gato negrothe black cat
los gatosnegroslos gatos negrosthe black cats
la florazulla flor azulthe blue flower
las floresazuleslas flores azulesthe blue flowers

Combined Agreement

Adjectives change to match both gender and number of the noun.

Examples

Noun (Spanish)Adjective (Spanish)Noun + Adjective (Spanish)Noun + Adjective (English)
el niñoaltoel niño altothe tall boy
la niñaaltala niña altathe tall girl
los niñosaltoslos niños altosthe tall boys
las niñasaltaslas niñas altasthe tall girls

Translate: 'The tall boy' into Spanish.


el niño alto

'Niño' is masculine singular, so the adjective is 'alto' (masculine singular).

Adjectives That Do Not Change

Some adjectives have one form for both masculine and feminine nouns. Only add -s for plural.

Examples

Noun (Spanish)Adjective (Spanish)Noun + Adjective (Spanish)Noun + Adjective (English)
el alumnointeligenteel alumno inteligentethe intelligent student (m.)
la alumnainteligentela alumna inteligentethe intelligent student (f.)
los alumnosinteligenteslos alumnos inteligentesthe intelligent students (m.)
las alumnasinteligenteslas alumnas inteligentesthe intelligent students (f.)

Special Cases

Adjectives Ending in -or, -án, -ón, -és

These adjectives add -a for the feminine form.

Adjectives That Change Meaning Based on Position

  • Before noun: Some adjectives have a different or more poetic meaning.
  • After noun: Adjective's usual descriptive meaning.
