Adjectives (Leaving Cert Spanish): Revision Notes
Comparative and superlative adjectives
Overview
Comparative and superlative adjectives allow you to make comparisons in Spanish. When you want to say someone is taller, something is more interesting, or express that someone is the best at something, you'll need these essential grammar structures. They help you describe differences between people, places, and things in everyday conversations.
Understanding comparatives and superlatives is crucial for expressing opinions, making descriptions, and having natural conversations in Spanish. These structures appear frequently in everyday speech and writing.
Rules & formation
Comparative adjectives
Spanish uses three main structures to compare two things:
1. Superiority (more than)
- Structure: más + adjective + que
- Usage: When something has more of a quality than something else
2. Inferiority (less than)
- Structure: menos + adjective + que
- Usage: When something has less of a quality than something else
3. Equality (as...as)
- Structure: tan + adjective + como
- Usage: When two things have the same degree of a quality
Superlative adjectives
To express the highest degree of a quality, Spanish uses the structure el/la/los/las + (noun) + más + adjective. This construction is used when something is the most or least of all in a group. The definite article (el/la/los/las) must agree with the gender and number of the noun.
The definite article in superlatives must always agree with the gender and number of the noun being described. This is one of the most common errors learners make.
Key forms
Regular comparative and superlative patterns
| Structure | Spanish | English |
|---|---|---|
| Superiority | más + adjective + que | more + adjective + than |
| Inferiority | menos + adjective + que | less + adjective + than |
| Equality | tan + adjective + como | as + adjective + as |
| Superlative | el/la/los/las + más + adjective | the most + adjective |
Irregular comparative and superlative forms
These four adjectives have special irregular forms that don't follow the standard patterns:
| Adjective | Comparative | Superlative |
|---|---|---|
| viejo/a (old) | mayor (older) | el/la mayor (the oldest) |
| joven (young) | menor (younger) | el/la menor (the youngest) |
| bueno/a (good) | mejor (better) | el/la mejor (the best) |
| malo/a (bad) | peor (worse) | el/la peor (the worst) |
These four irregular forms are essential to memorise as they don't follow the regular patterns and appear very frequently in Spanish conversation.
Example sentences
The following examples demonstrate how comparative and superlative structures work in context:
Comparative Examples:
Superiority:
- Ignacio es más alto que Álvaro. (Ignacio is taller than Álvaro.)
Inferiority:
- Álvaro es menos alto que Ignacio. (Álvaro is less tall than Ignacio.)
Equality:
- Leticia es tan alta como Susana. (Leticia is as tall as Susana.)
Superlative Examples:
- La chica más alta (The tallest girl)
- El libro más interesante (The most interesting book)
Using Irregular Forms:
- Mi hermano es mayor que yo. (My brother is older than me.)
- Ella es la mejor estudiante. (She is the best student.)
- Este es el peor día. (This is the worst day.)
In these examples, notice how the comparative structures help establish relationships between different people and things, while superlatives identify the extreme within a group.
Common mistakes & tips
Understanding these common errors will help you avoid them in your own Spanish:
Mistake 1: Using "más" with irregular comparatives
- ❌ Incorrect: más mayor, más mejor
- ✅ Correct: mayor, mejor
Why this happens: The irregular forms already contain the comparative meaning, so don't add "más"
Mistake 2: Forgetting gender and number agreement in superlatives
- ❌ Incorrect: La chica el más alto
- ✅ Correct: La chica más alta
Remember: The definite article and adjective must match the gender and number of the noun
Mistake 3: Confusing "tan...como" with "tanto...como"
- Use tan + adjective + como for comparisons of equality
- Tanto is used with nouns, not adjectives
Age vs. Appearance Tip: Remember that mayor and menor are often used for age comparisons, while más viejo/joven can refer to physical appearance.

Remember!
Key Points to Remember:
- Use más...que for superiority, menos...que for inferiority, and tan...como for equality comparisons
- Superlatives need the definite article (el/la/los/las) + más + adjective
- Four key irregular forms must be memorised: mayor/menor (age), mejor/peor (quality)
- Always check gender and number agreement with the definite article and adjectives
- Never use "más" with irregular comparative forms like mayor, menor, mejor, or peor
