In Spanish, adjectives need to match the nouns they describe. This means they should agree in two main ways: gender (like boy or girl) and number (like one or many). Here’s a simple guide to help you understand:

1. Gender Agreement:

   • For masculine nouns: Adjectives usually end in -o.
     Example: El coche rojo (The red car).
   • For feminine nouns: Adjectives usually end in -a.
     Example: La casa roja (The red house).

2. Number Agreement:

   • For singular nouns: Use the singular form of the adjective.
     Example: El niño feliz (The happy boy).
   • For plural nouns: Add -s or -es to the adjective.
     Example: Los niños felices (The happy boys).

Getting this agreement right is really important. It helps you make clear and correct sentences in Spanish!
