Adjectives (AQA A-Level Spanish): Revision Notes
Adjectives
Overview
Adjectives in Spanish (los adjetivos) are words that describe nouns. They must match the noun they describe in both gender (masculine or feminine) and number (singular or plural). Getting agreement, position, and form correct is essential for accurate Spanish communication in both speaking and writing.
Adjective agreement
Spanish adjectives need to agree with the noun they describe in two ways: gender and number. This agreement is not optional—it directly affects grammatical accuracy.
Gender agreement
Most adjectives follow a simple pattern for gender agreement:
Adjectives ending in -o change to -a for feminine nouns:
- un chico alto → una chica alta (a tall boy → a tall girl)
Adjectives ending in -e or a consonant stay the same for both genders:
- un examen difícil / una situación difícil (a difficult exam / a difficult situation)
Number agreement
To make adjectives plural, follow these rules:
Add -s after a vowel:
- libro interesante → libros interesantes (interesting book → interesting books)
Add -es after a consonant:
- ciudad moderna → ciudades modernas (modern city → modern cities)
Exam focus
Agreement errors are among the most heavily penalised mistakes in writing tasks. Always double-check that your adjectives match the gender and number of the noun they describe.
Position of adjectives
Where you place an adjective in relation to the noun changes its meaning and emphasis. Understanding this distinction is important for natural-sounding Spanish.
Adjectives after the noun (most common)
Most adjectives come after the noun and provide descriptive or factual information:
- una casa grande (a big house)
- un problema serio (a serious problem)
This is the standard position for physical descriptions, colours, nationalities, and factual qualities.
Adjectives before the noun
Placing adjectives before the noun adds subjective meaning, emphasis, or an emotional or stylistic effect:
- una gran idea (a great idea)
- un viejo amigo (a long-standing friend)
This position is less common and often signals that the speaker is being more expressive or emphasising a quality.
Change of meaning with position
Some adjectives change meaning depending on whether they come before or after the noun:
Position Changes Meaning
| Adjective | Before noun | After noun |
|---|---|---|
| viejo | long-standing | old |
| nuevo | different | brand new |
| pobre | unfortunate | poor |
| cierto | certain | true |
Examples:
- un viejo amigo = a long-standing friend
- un amigo viejo = an old (elderly) friend
This meaning shift is considered a high-level feature and demonstrates sophisticated understanding of Spanish.
Apocopation
Apocopation refers to the shortening of certain adjectives when they appear before a masculine singular noun. The adjective drops its final syllable in this specific position.
Common shortened forms
Apocopation Rules
| Full form | Shortened form | Example |
|---|---|---|
| grande | gran | un gran problema (a big problem) |
| bueno | buen | un buen amigo (a good friend) |
| malo | mal | un mal día (a bad day) |
| primero | primer | el primer año (the first year) |
Memory aid: Think of "GAN" – Gran, bueN, maL
Apocopation only applies to masculine singular nouns. With feminine nouns or plural nouns, use the full form:
- una grande casa → una gran casa (feminine: shortened)
- unos buenos amigos (masculine plural: full form)
Adjectives used as nouns
When the noun is understood or has already been mentioned, adjectives can function as nouns on their own. This structure helps avoid repetition and creates more natural Spanish.
Structure
article + adjective
Examples:
- el pobre (the poor man)
- la roja (the red one)
- los norteamericanos (the North Americans / the Americans)
This construction is frequently used in descriptions, opinions, and comparative writing. It allows you to refer back to something without repeating the noun.
Adjective as Noun in Context
¿Cuál bolígrafo prefieres? Prefiero el azul.
(Which pen do you prefer? I prefer the blue one.)
The adjective azul functions as a noun because the context makes clear we're talking about a pen.
Indefinite adjectives
Indefinite adjectives (alguno, cualquiera, otro) describe non-specific nouns. They indicate "some," "any," or "other" without specifying exactly which one.
Common forms and usage
Alguno / alguna – some, any
- algún problema (some problem)
Cualquiera – any (at all)
- cualquier persona (any person)
Otro / otra – other, another
- otro día (another day)
Important distinction
Alguno becomes ninguno in negative sentences:
- No tengo ningún problema. (I don't have any problem.)
Interrogative and exclamatory adjectives
These adjectives are used in questions and exclamations. They always carry an accent to distinguish them from relative forms.
| Adjective | Use | Example |
|---|---|---|
| qué | what | ¿Qué problema hay? (What problem is there?) |
| cuánto/a(s) | how much/many | ¿Cuántos años tienes? (How many years do you have? = How old are you?) |
Key distinction:
- Interrogative/exclamatory forms have an accent: qué, cuánto
- Relative forms do not have an accent: que, cuanto
The accent is mandatory and omitting it is a common error.
Relative adjective cuyo (A-Level)
Cuyo is an A-Level structure that expresses possession. It means "whose" or "of which" and agrees with the thing owned, not the owner.
Structure
noun + cuyo/a(s) + noun
Examples:
- El chico cuyo padre trabaja aquí… (The boy whose father works here…)
- La mujer cuyas hijas estudian medicina… (The woman whose daughters study medicine…)
Critical rule for cuyo
Agreement is with the second noun (the thing possessed), not the first noun (the owner):
- La mujer (feminine) + cuyas hijas (feminine plural) – agreement is with hijas, not mujer
Memory aid: Cuyo agrees with the SECOND noun, not the first
Using cuyo correctly
El chico cuyo padre trabaja aquí es mi amigo.
(The boy whose father works here is my friend.)
Here, cuyo is masculine singular because it agrees with padre (the thing possessed), not chico (the possessor).
Strong possessive adjectives
Strong possessive adjectives (mío, tuya, suyo, nuestro, vuestro) emphasise or clarify ownership. They are stronger and more emphatic than the weak forms (mi, tu, su).
Forms (example: mío)
| Gender/number | Form |
|---|---|
| masculine singular | mío |
| feminine singular | mía |
| masculine plural | míos |
| feminine plural | mías |
Other strong possessives follow the same pattern: tuyo/tuya/tuyos/tuyas, suyo/suya/suyos/suyas, etc.
Structure
article + possessive adjective
Examples:
- Es el mío. (It's mine.)
- Son las tuyas. (They're yours.)
Contrast with weak possessives
The strong form adds emphasis:
- mi casa (my house – neutral, weak possessive)
- la casa mía (my house – emphatic, strong possessive)
Example in context:
No es tu libro, es el mío. (It's not your book, it's mine.)
The strong possessive el mío provides emphasis and clarity about ownership.
Common mistakes and tips
Be aware of these frequent errors:
Agreement with the wrong noun:
- ❌ una problema grave
- ✔ un problema grave (problema is masculine despite ending in -a)
Forgetting apocopation:
- ❌ un bueno amigo
- ✔ un buen amigo
Incorrect use of cuyo:
- Students often confuse cuyo with de quien or try to make it agree with the wrong noun.
- Remember: cuyo agrees with what is owned, not the owner.
Missing accents on interrogative adjectives:
- ❌ ¿Que problema hay?
- ✔ ¿Qué problema hay?
The accent is not decorative—it changes meaning and is grammatically required.
Practice examples with explanations
Example 1: Agreement and apocopation
Spanish: Un problema grave
English: A serious problem
Explanation: Problema is masculine despite its -a ending, so the adjective stays in the masculine form grave. The adjective comes after the noun because it provides factual description.
Example 2: Strong possessive
Spanish: ¿Cuáles son los tuyos?
English: Which ones are yours?
Explanation: The strong possessive los tuyos (masculine plural) is used for emphasis. The article los comes before the possessive adjective.
Example 3: Cuyo
Spanish: La mujer cuyo hijo vive aquí
English: The woman whose son lives here
Explanation: Cuyo agrees with hijo (masculine singular), not with mujer. It expresses the possessive relationship between the woman and her son.
Example 4: Position changes meaning
Spanish: un pobre hombre vs un hombre pobre
English: an unfortunate man vs a poor man (financially)
Explanation: When pobre comes before the noun, it means "unfortunate" or "pitiful." After the noun, it means "poor" in the financial sense. This demonstrates how position affects meaning.
Example 5: Adjective as noun
Spanish: Prefiero el azul.
English: I prefer the blue one.
Explanation: The adjective azul functions as a noun here. The context makes clear what object is being discussed (perhaps a shirt or car), so repeating the noun is unnecessary.
Example 6: Interrogative adjective
Spanish: ¿Qué libros lees?
English: What books are you reading?
Explanation: Qué is an interrogative adjective agreeing with libros. The accent on qué is mandatory in questions.
Key Points to Remember:
- Adjectives must match the noun in both gender and number—agreement errors are heavily penalised in exams.
- Most adjectives follow the noun for factual descriptions, but placing them before adds emphasis or subjective meaning.
- Certain adjectives (grande, bueno, malo, primero) shorten before masculine singular nouns—this is called apocopation.
- Cuyo is an A-Level feature that means "whose"—it agrees with the thing owned, not the owner.
- Interrogative and exclamatory adjectives (qué, cuánto) always carry an accent to distinguish them from relative forms.
