In Spanish, adjectives, which describe nouns, need to match the nouns in two main ways: gender and number. Let’s break this down into simple rules.

1. Gender Agreement:

• Masculine Nouns: These usually end with -o. The adjective will also end in -o to match.

  • For example:
    "El libro rojo" means "The red book."

• Feminine Nouns: These often end with -a. The adjective will change to end in -a too.

  • For example:
    "La casa roja" means "The red house."

2. Number Agreement:

• For Plural Nouns:

  • If an adjective ends with a vowel (like -o or -a), just add -s.

    • For example:
      "Los libros rojos" means "The red books."

  • If an adjective ends with a consonant, add -es.

    • For example:
      "Las casas rojas" means "The red houses."

3. Exceptions:

Some adjectives do not change for gender or number. For example:

• Words like “joven” (young) or “feliz” (happy) stay the same.
  • For instance:
    "Los niños jóvenes" means "The young boys," and
    "Las niñas jóvenes" means "The young girls."

Remembering these rules will make learning Spanish easier and more fun!
