TL;DR

• Spanish adjectives describe nouns and must match in gender (masculine/feminine) and number (singular/plural).
• Most adjectives follow predictable endings like -o → -a, -os → -as.
• Placement matters: adjectives usually follow nouns, but move before nouns to add emotion, emphasis, or subjective meaning.
• Some adjectives change meaning depending on placement (e.g., pobre hombre vs. hombre pobre).
• You’ll learn faster by practicing adjectives inside real sentences and stories—not isolated lists.

Spanish Adjectives: The Complete Guide

Spanish adjectives (los adjetivos) are words that describe nouns — people, places, things, or ideas.
To use them correctly, you must understand agreement (gender + number) and placement (before vs. after nouns).

According to the Wikipedia’s Spanish grammar article, adjectives play a central role in expressing nuance and detail in Spanish.

What Are Spanish Adjectives?

Spanish adjectives are descriptive words that tell you what someone or something is like.

Example:

• La casa grande — “the big house”
• El perro feliz — “the happy dog”
• Los estudiantes inteligentes — “the intelligent students”

As noted in Wikipedia’s “Spanish grammar – Nouns and adjectives”, adjectives must agree with the noun they modify — a key difference from English.

Gender Agreement in Spanish Adjectives

Spanish adjectives match the gender of nouns:

1. Adjectives ending in -o

They change based on gender:

2. Adjectives ending in -e or a consonant

They do not change for gender:

• el estudiante inteligente
• la estudiante inteligente
• un carro difícil
• una tarea difícil

Number Agreement: Singular vs. Plural

To make adjectives plural:

If it ends in a vowel → add -s

• alto → altos
• grande → grandes

If it ends in a consonant → add -es

• fácil → fáciles
• joven → jóvenes

If it ends in -z → change z → c + -es

• feliz → felices
• capaz → capaces

These pluralization rules are validated by the Spanish orthography rules outlined on Wikipedia.

Where Do Spanish Adjectives Go in a Sentence?

Most adjectives come AFTER the noun

This is the default position.

• una casa moderna
• un coche rápido
• un día largo

Some adjectives go BEFORE the noun for emotion or emphasis

These adjectives express:

• opinion
• beauty
• quantity
• subjectivity

Examples:

• una bella historia — a beautiful story
• mi mejor amigo — my best friend
• muchas personas — many people

This concept is also explained in the “Adjective placement” subsection of Spanish grammar on Wikipedia.

Spanish Adjectives That Change Meaning

Some adjectives change meaning depending on whether they appear before or after the noun.

These dual meanings are widely documented in descriptive Spanish grammar sources, including Wikipedia.
