Adjectives (Junior Cert Spanish): Revision Notes
Adjectives
Overview
Adjectives are words that describe nouns, giving us more information about people, places, and things. In Spanish, adjectives work differently from English because they must match the noun they describe in both gender (masculine or feminine) and number (singular or plural). This matching is called agreement, and it's essential for speaking Spanish correctly.
Agreement is the foundation of Spanish adjective usage. Unlike English, where adjectives never change form, Spanish adjectives are like chameleons - they constantly adapt to match their nouns!
Rules & formation
Adjective agreement
Spanish adjectives change their endings to match the noun they describe. The process involves three key steps:
Step-by-step Agreement Process:
Step 1: Identify if the noun is masculine or feminine, singular or plural Step 2: Choose the correct adjective ending to match Step 3: Place the adjective in the correct position (usually after the noun)
Position rules
Most Spanish adjectives come after the noun they describe, unlike in English where they come before. However, some common adjectives always come before the noun.
Adjectives that come before the noun:
- mucho (much/many)
- poco (little/few)
- primero (first)
- segundo (second)
- tercero (third)
- próximo (next)
- último (last)
- alguno (some/any)
- ninguno (no/none)
Tables of key forms
Understanding how adjectives change their forms is crucial for proper Spanish communication.
Adjective agreement endings
| Adjective ending | Masculine singular | Feminine singular | Masculine plural | Feminine plural |
|---|---|---|---|---|
| -o/-a | alto (tall) | alta (tall) | altos (tall) | altas (tall) |
| -e | importante (important) | importante (important) | importantes (important) | importantes (important) |
| consonant | azul (blue) | azul (blue) | azules (blue) | azules (blue) |
Notice how adjectives ending in -e or consonants don't change for gender - only for number by adding -s or -es.
Exceptions - adjectives ending in -or
| Type | Masculine singular | Feminine singular | Masculine plural | Feminine plural |
|---|---|---|---|---|
| -or ending | trabajador (hardworking) | trabajadora (hardworking) | trabajadores (hardworking) | trabajadoras (hardworking) |
Nationality adjectives ending in -s
| Type | Masculine singular | Feminine singular | Masculine plural | Feminine plural |
|---|---|---|---|---|
| -s ending | inglés (English) | inglesa (English) | ingleses (English) | inglesas (English) |
Short forms of adjectives
Some adjectives have shortened forms when they come before a masculine singular noun:
| Full form | English | Short form | When to use |
|---|---|---|---|
| bueno | good | buen | Before masculine singular nouns |
| malo | bad | mal | Before masculine singular nouns |
| primero | first | primer | Before masculine singular nouns |
| alguno | some/any | algún | Before masculine singular nouns |
| ninguno | no/none | ningún | Before masculine singular nouns |
Example sentences
Here are practical examples showing how adjective agreement and positioning work in real Spanish sentences:
Agreement examples:
- La falda amarilla (the yellow skirt) - feminine singular
- Los coches azules (the blue cars) - masculine plural
- Una película importante (an important film) - feminine singular
Position examples:
- Tengo muchos amigos (I have many friends) - mucho comes before
- Es una falda azul (It's a blue skirt) - azul comes after
- Fue una gran película (It was a great film) - grande shortens to gran and comes before
Short form examples:
- Un buen estudiante (a good student) - bueno becomes buen
- El primer día (the first day) - primero becomes primer
- Algún problema (some problem) - alguno becomes algún
Special construction with 'lo':
- Lo bueno (the good thing) - use lo + masculine singular adjective
- Lo peor es que... (the worst thing is that...) - creates a noun from an adjective
Common mistakes & tips
Learning from common errors will help you master Spanish adjectives more quickly.
Mistake 1: Forgetting gender agreement ❌ La coche rojo (mixing feminine article with masculine noun and adjective) ✅ El coche rojo (the red car - all masculine)
Mistake 2: Wrong position with common adjectives ❌ Estudiantes muchos ✅ Muchos estudiantes (many students - mucho goes before)
Mistake 3: Not using short forms ❌ Un bueno amigo ✅ Un buen amigo (a good friend - use short form before masculine singular)
Helpful Tip: Remember that colours, size, and descriptive adjectives usually come after the noun, whilst quantity and order adjectives come before.

Remember!
Key Points to Remember:
- Spanish adjectives must agree with nouns in both gender and number - this is non-negotiable!
- Most adjectives come after the noun, but quantity and order words come before
- Five common adjectives have short forms before masculine singular nouns: bueno→buen, malo→mal, primero→primer, alguno→algún, ninguno→ningún
- Use "lo + masculine singular adjective" to mean "the [adjective] thing"
- When in doubt, put descriptive adjectives after the noun - this works 80% of the time!
