Introduction
In English, adjectives never change: "a tall man," "a tall woman," "tall people." In Spanish, adjectives must agree with the noun in both gender (masculine/feminine) and number (singular/plural). They also usually go after the noun, not before.
Gender Agreement
Adjectives ending in -o / -a
Most adjectives have four forms:
| Singular | Plural | |
|---|---|---|
| Masculine | alto | altos |
| Feminine | alta | altas |
- el gato negro — the black cat (m.)
- la gata negra — the black cat (f.)
- los gatos negros — the black cats (m.)
- las gatas negras — the black cats (f.)
Adjectives ending in -e or a consonant
These have only two forms (singular and plural) — no gender change:
| Singular | Plural | |
|---|---|---|
| -e | grande | grandes |
| consonant | fácil | fáciles |
- un problema grande — a big problem
- una casa grande — a big house
- los exámenes fáciles — the easy exams
Adjectives of nationality ending in a consonant
These do add -a for feminine:
- un chico español → una chica española
- un hombre francés → una mujer francesa
- un escritor japonés → una escritora japonesa
Number Agreement
- Add -s if the adjective ends in a vowel: alto → altos
- Add -es if it ends in a consonant: fácil → fáciles
- If it ends in -z, change to -ces: feliz → felices
Placement: After the Noun
The default position for Spanish adjectives is after the noun:
- una casa blanca — a white house
- un libro interesante — an interesting book
- agua fría — cold water
This is the opposite of English and is one of the most common mistakes beginners make.
Exceptions: Before the Noun
Some adjectives go before the noun, usually when they express a subjective quality or quantity:
- buen / mal: un buen amigo (a good friend)
- gran: una gran ciudad (a great city)
- Numbers: tres libros (three books)
- Possessives: mi casa (my house)
Note: Bueno shortens to buen and malo to mal before a masculine singular noun. Grande shortens to gran before any singular noun.
Meaning Changes by Position
A few adjectives change meaning depending on placement:
| Before noun | After noun |
|---|---|
| un gran hombre (a great man) | un hombre grande (a big/tall man) |
| un viejo amigo (a long-time friend) | un amigo viejo (an elderly friend) |
| un pobre niño (a poor/unfortunate child) | un niño pobre (a child without money) |
| un nuevo carro (a new-to-me car) | un carro nuevo (a brand-new car) |
