1. Understanding Spanish Adjectives

Spanish adjectives are words that describe or modify a noun. They provide essential information about the noun’s qualities, characteristics or state. In Spanish, adjectives agree in gender (masculine or feminine) and number (singular or plural) with the noun they modify.

Examples of Spanish Adjectives:

• grande (big)
• pequeño (small)
• feliz (happy)
• triste (sad)

2. The Role of Gender and Number in Adjectives

As mentioned earlier, Spanish adjectives agree in gender and number with the noun they modify. This means that their form may change depending on the noun.

Gender Agreement

• Masculine adjectives usually end in -o. To form the feminine version, replace the -o with -a. Example: rápido (fast, masculine) → rápida (fast, feminine)
• Adjectives ending in -e or a consonant usually have the same form for both masculine and feminine. Example: inteligente (intelligent, both masculine and feminine)

Number Agreement

• To form the plural of adjectives, follow these rules:
• If the adjective ends in a vowel, add -s. Example: grande (big) → grandes (big, plural)
• If the adjective ends in a consonant, add -es. Example: débil (weak) → débiles (weak, plural)

3. Forming Comparative Sentences

Comparatives in Spanish are used to compare two things, people, or ideas. They can express equality, superiority, or inferiority.

Comparatives of Equality

To express that two things are equal in some aspect, use the structure:

• tan + adjective + como Example: Juan es tan alto como Pedro. (Juan is as tall as Pedro.)

Comparatives of Superiority

To express that something is “more” in some aspect, use the structure:

• más + adjective + que Example: El coche es más rápido que la bicicleta. (The car is faster than the bicycle.)

Comparatives of Inferiority

To express that something is “less” in some aspect, use the structure:

• menos + adjective + que Example: Ella es menos inteligente que su hermano. (She is less intelligent than her brother.)

4. Irregular Comparatives

Some Spanish adjectives have irregular comparative forms. These adjectives do not follow the regular pattern of adding más or menos before the adjective.

Common Irregular Comparatives:

Adjective	Comparative	Example
bueno (good)	mejor (better)	María es mejor estudiante que Luis. (María is a better student than Luis.)
malo (bad)	peor (worse)	Este libro es peor que el otro. (This book is worse than the other one.)
grande (big)	mayor (older)	Mi hermano es mayor que yo. (My brother is older than me.)
pequeño (small)	menor (younger)	Ella es menor que su hermana. (She is younger than her sister.)

5. Using Comparatives with Quantifiers

In Spanish, you can also use comparatives to express a greater or lesser quantity of something. This is done using quantifiers, such as mucho (much), poco (little), tanto (so much), and cuánto (how much).

Examples:

• Tengo más libros que tú. (I have more books than you.)
• Hay menos personas en la playa hoy. (There are fewer people at the beach today.)

6. Making Superlative Statements

Superlatives are used to express that something is “the most” or “the least” in some aspect. In Spanish, superlatives are formed by adding el/la/los/las before the comparative form.

Examples:

• El restaurante más caro de la ciudad. (The most expensive restaurant in the city.)
• La película menos interesante que he visto. (The least interesting movie I have seen.)

For irregular adjectives, use their irregular comparative forms with the definite article:

• Ella es la mejor cantante. (She is the best singer.)
• Este es el peor día de mi vida. (This is the worst day of my life.)
