Spanish Adjectives: Complete A1 Beginner’s Guide
◄ Back to A1 Grammar Hub | Practice with Adjectives Quiz ►
Adjectives describe people, places, and things — they’re what bring your Spanish to life. English adjectives stay the same no matter what they describe; Spanish adjectives change to match the gender and number of the noun. Once you learn the patterns, you can describe anything.
Key Takeaways
- Spanish adjectives usually come after the noun: el coche rojo (the red car).
- Most adjectives ending in -o change to -a for feminine nouns: rojo → roja.
- Adjectives ending in -e or a consonant have the same form for both genders: inteligente, azul.
- Adjectives agree in number too: add -s after a vowel, -es after a consonant.
- A few common adjectives shorten before masculine singular nouns: bueno → buen, malo → mal, primero → primer, tercero → tercer.
- A small set of adjectives change meaning depending on whether they come before or after the noun: un gran hombre vs. un hombre grande.
Adjective Placement
In English, adjectives come before the noun: “the red car.” In Spanish, adjectives usually come after the noun:
- English: adjective + noun — “the red car”
- Spanish: noun + adjective — el coche rojo (the car red)
Basic structure: noun + adjective
- la casa grande (the big house)
- el libro interesante (the interesting book)
- un hombre alto (a tall man)
Some adjectives — numbers, quantity words, demonstratives, possessives — come before the noun. And a few descriptive adjectives change meaning depending on position. Both are covered below.
Gender Agreement
Adjectives must match the gender of the noun they describe.
Masculine nouns → adjective usually ends in -o
- el libro rojo (the red book)
- el coche pequeño (the small car)
- un día bueno (a good day)
Feminine nouns → adjective usually ends in -a
- la casa roja (the red house)
- la mesa pequeña (the small table)
- una película buena (a good movie)
Adjectives ending in -e or a consonant → same form for both genders
- el hombre inteligente (the intelligent man)
- la mujer inteligente (the intelligent woman)
- el libro azul (the blue book)
- la camisa azul (the blue shirt)
These don’t change with gender — inteligente stays inteligente whether the person is male or female. Only the article and any other agreeing words change.
Making Adjectives Plural
Adjectives agree in number as well as gender.
Ends in a vowel → add -s
- libro rojo → libros rojos
- casa grande → casas grandes
Ends in a consonant → add -es
- hombre joven → hombres jóvenes
- mujer fácil → mujeres fáciles
Ends in -z → change -z to -c, then add -es
- niño feliz → niños felices
Note that some adjectives gain a written accent in the plural to keep the stress in the right place: joven → jóvenes.

Shortened Adjectives
Four common adjectives drop their final *-o* before a masculine singular noun:
| Full form | Shortened | Example |
|---|---|---|
| bueno | buen | un buen libro (a good book) |
| malo | mal | un mal día (a bad day) |
| primero | primer | el primer piso (the first floor) |
| tercero | tercer | el tercer hombre (the third man) |
The full form is used everywhere else:
- una buena casa (a good house) — feminine, so full form
- una mala idea (a bad idea) — feminine
- la primera vez (the first time) — feminine
- la tercera mujer (the third woman) — feminine
Also note that primero and tercero only shorten before masculine singular nouns. Before feminine nouns, and in the plural, they stay full: los primeros días, las primeras veces.
Adjective Position Exceptions
Adjectives that normally come before the noun:
- Numbers — los tres libros (the three books)
- Quantity — mucho tiempo (much time)
- Demonstratives — esta casa (this house)
- Possessives — mi amigo (my friend)
These are a closed set — they don’t follow the noun+adjective rule.
Adjectives that change meaning based on position:
A few descriptive adjectives shift meaning when they move:
| Before the noun | After the noun |
|---|---|
| un gran hombre (a great man) | un hombre grande (a big man) |
| un pobre hombre (a poor, unfortunate man) | un hombre pobre (a poor, not-rich man) |
With grande, the shortened form gran before the noun means “great” in a figurative sense. The full form grande after the noun means “big” in a physical sense. Same adjective, different meaning.
With pobre, the position changes the sense from “pitiable” (before) to “penniless” (after).
Common Mistakes to Avoid
- Using English word order. Spanish adjectives usually come after the noun: el coche rojo, not el rojo coche.
- Forgetting gender agreement. La casa es roja, not la casa es rojo.
- Forgetting number agreement. Los libros rojos, not los libros rojo.
- Using the shortened form incorrectly. Buen, mal, primer, and tercer only shorten before masculine singular nouns. Una buen casa is wrong; una buena casa is correct.

| Situation | Masculine | Feminine | Example |

Frequently Asked Questions
Usually after the noun: el coche rojo (the red car), la casa grande (the big house). This is the opposite of English, where adjectives come before. A few adjectives come before the noun — numbers, quantity words, demonstratives, and possessives — and a small set changes meaning depending on position.
Match the noun’s gender. Masculine nouns take -o: el libro rojo. Feminine nouns take -a: la casa roja. This only applies to adjectives that have both forms (*rojo/roja*, *pequeño/pequeña*). Adjectives ending in -e or a consonant have the same form for both genders.
No. Adjectives ending in -e or a consonant have the same form for masculine and feminine: el hombre inteligente / la mujer inteligente, el libro azul / la camisa azul. The adjective doesn’t change — only the article and any other agreeing words change. They do still add -s or -es in the plural.
Three rules. Ends in a vowel → add -s: rojo → rojos. Ends in a consonant → add -es: joven → jóvenes. Ends in -z → change z to c and add -es: feliz → felices. Some adjectives gain a written accent in the plural to keep the stress in the right place.
Un gran hombre means “a great man” — gran before the noun is the shortened form of grande and carries a figurative meaning (greatness, importance). Un hombre grande means “a big man” — grande after the noun keeps its literal meaning (physical size). Same adjective, different position, different meaning.
Four common adjectives shorten before a masculine singular noun: bueno → buen (un buen libro), malo → mal (un mal día), primero → primer (el primer piso), tercero → tercer (el tercer hombre). Before feminine nouns and in the plural, the full form is used: una buena casa, los primeros días.
Four categories: numbers (los tres libros), quantity words (mucho tiempo), demonstratives (esta casa), and possessives (mi amigo). These come before the noun by rule. Descriptive adjectives normally come after — the exceptions are the meaning-shift cases like gran and pobre.
No. Nationalities are lowercase in Spanish: español, mexicano, americano, francés, italiano. This is different from English, which capitalizes them. The same rule applies to languages and days of the week — Spanish uses lowercase for all of these.
Yes. Adjectives agree with the noun in both gender and number. El libro rojo (masculine singular) → los libros rojos (masculine plural). La casa roja (feminine singular) → las casas rojas (feminine plural). Both endings change at once: -o → -os, -a → -as.
Using English word order — putting the adjective before the noun. “The red car” becomes el coche rojo, not el rojo coche. This is the mistake English speakers make most often, because it feels natural to translate directly. Once you internalize “noun first, adjective second,” everything else — gender and number agreement — follows from the same habit.
