Descriptive adjectives in Spanish are words that express qualities, characteristics, or states of people, places, things, or ideas. They provide more information about the noun and make sentences more vivid and precise. Unlike in English, Spanish adjectives must agree in gender (masculine/feminine) and number (singular/plural) with the nouns they describe.
  • Modify nouns by expressing attributes, emotions, or conditions.
  • Must match the noun's gender: masculine or feminine.
  • Must match the noun's number: singular or plural.
  • Can be placed before or after the noun, with some nuances in meaning.
Descriptive adjectives describe qualities, characteristics, and states.

Agreement in Gender and Number

Gender

Most Spanish adjectives have two forms: one for masculine nouns (usually ending in -o) and one for feminine nouns (usually ending in -a).
MasculineFeminine
altoalta
inteligenteinteligente*
\* Adjectives ending in -e or a consonant are usually the same for both genders.
  • Masculine: Used with masculine nouns (usually ending in -o).
  • Feminine: Used with feminine nouns (usually ending in -a, or -e/-consonant forms remain the same).
Most change from -o (masc.) to -a (fem.); some remain the same for -e or consonant endings.

Number

Adjectives also change to match the number of the noun: add -s for vowels, -es for consonants.
SingularPlural
altoaltos
altaaltas
felizfelices
  • Singular: Used for one item/person.
  • Plural: Add -s (if adjective ends in a vowel) or -es (if it ends in a consonant).
Add -s if the adjective ends in a vowel; add -es if it ends in a consonant.

Placement of Adjectives

Most descriptive adjectives come after the noun:
  • Common placement: Noun + Adjective
el coche rojo (the red car)
Some adjectives can precede the noun for emphasis or stylistic reasons, sometimes changing the meaning:
  • Before noun:
un gran hombre (a great man) vs. un hombre grande (a big man)
  • Adjectives like bueno, malo, primero, último often appear before the noun, sometimes with a shortened form (buen, mal).
They usually go after the noun.
