Adjectives in Spanish work differently from English in three key ways: they must agree in gender and number with the noun they describe, they usually come after the noun (not before), and some adjectives shorten before masculine nouns. This guide explains all three principles clearly and covers comparatives and superlatives.

Gender and Number Agreement

Every Spanish adjective must match the noun it modifies in gender (masculine/feminine) and number (singular/plural). This is the fundamental rule of Spanish adjectives.

Four-Form Adjectives (most common)

Adjectives ending in -o have four forms:

MasculineFeminine
Singularalto (tall)alta
Pluralaltosaltas
  • El chico es alto. — The boy is tall.
  • La chica es alta. — The girl is tall.
  • Los chicos son altos. — The boys are tall.
  • Las chicas son altas. — The girls are tall.

Two-Form Adjectives

Adjectives ending in -e or most consonants have only two forms (singular and plural — same for both genders):

Masculine & Feminine
Singularinteligente / difícil / azul
Pluralinteligentes / difíciles / azules
  • El problema es difícil. / La pregunta es difícil.
  • Los problemas son difíciles. / Las preguntas son difíciles.

Adjectives of Nationality

Nationality adjectives ending in a consonant add -a for feminine:

  • español → española (Spanish)
  • inglés → inglesa (English)
  • francés → francesa (French)
  • alemán → alemana (German)
  • australiano → australiana (Australian — already ends in -o)

Position: After or Before the Noun?

The default position for Spanish adjectives is after the noun — the opposite of English:

  • un coche rojo — a red car (NOT un rojo coche)
  • una persona inteligente — an intelligent person
  • el libro interesante — the interesting book

Adjectives That Go BEFORE the Noun

Some adjectives typically or always precede the noun:

  • Numbers and ordinals: tres libros, el primer día
  • Possessives: mi casa, tu coche, nuestro país
  • Demonstratives: este libro, esa ciudad, aquellos años
  • Indefinite quantities: mucho dinero, poco tiempo, bastante gente
  • bueno/malo before noun: changes meaning (see below)

Adjectives That Change Meaning by Position

Some adjectives carry different meanings depending on whether they come before or after the noun:

AdjectiveAfter noun (objective)Before noun (subjective/figurative)
grandeun hombre grande — a physically big manun gran hombre — a great man
pobreuna familia pobre — a financially poor familyuna pobre familia — an unfortunate/pitiful family
viejoun amigo viejo — an elderly friendun viejo amigo — a long-standing/old friend
únicouna solución única — a unique/original solutionla única solución — the only solution
ciertoinformación cierta — certain/definite informationcierta información — certain (some) information

Shortened Adjective Forms (Apocope)

Several common adjectives shorten when placed before a masculine singular noun:

Full formShort form (before masc. sing.)Example
buenobuenun buen libro (a good book)
malomalun mal día (a bad day)
primeroprimerel primer piso (the first floor)
tercerotercerel tercer capítulo (the third chapter)
grandegranun gran hombre (a great man)
cualquieracualquiercualquier día (any day)
santosanSan Pablo (Saint Paul) — not before Do- or To-

These short forms are only used before masculine singular nouns. The full form is used in all other positions: el libro es bueno, una buena película.

Comparatives

Spanish comparatives follow simple patterns:

More than / Less than / As ... as

  • más + adjective + que = more ... than
    Madrid es más grande que Salamanca. — Madrid is bigger than Salamanca.
  • menos + adjective + que = less ... than
    Este libro es menos interesante que el otro. — This book is less interesting than the other.
  • tan + adjective + como = as ... as
    El español es tan difícil como el italiano. — Spanish is as difficult as Italian.

Irregular Comparatives

AdjectiveComparativeMeaning
bueno (good)mejorbetter
malo (bad)peorworse
grande (big/old)mayorbigger / older
pequeño (small/young)menorsmaller / younger

Superlatives

The superlative (the most / the least) is formed with the definite article + más/menos:

  • el/la/los/las + más/menos + adjective
  • Madrid es la ciudad más grande de España. — Madrid is the biggest city in Spain.
  • Es el peor momento para llamar. — It is the worst moment to call.
  • Es la mejor paella que he comido. — It is the best paella I have eaten.

Absolute Superlative (-ísimo)

Adding -ísimo/a/os/as to an adjective expresses an extreme degree — "extremely" or "very very":

  • grande → grandísimo — extremely big
  • bueno → buenísimo — absolutely excellent
  • fácil → facilísimo — extremely easy
  • rico → riquísimo — absolutely delicious
  • caro → carísimo — extremely expensive

This form is very common in everyday spoken Spanish: ¡Está buenísimo! — It's absolutely delicious!
