In Spanish, adjectives change based on whether they describe a boy (masculine) or a girl (feminine).

Key Rules

1. Masculine vs. Feminine:

   • Adjectives for boys usually end with -o.
     • For example, alto means "tall."
   • Adjectives for girls usually end with -a.
     • For example, alta also means "tall."

2. Making Words Plural:

   • To make nouns plural, you add -s or -es:
     • For boys: altos (tall, plural).
     • For girls: altas (tall, plural).

Sentence Structure

• Here’s how to use these in sentences:
  • For boys: El chico alto juega. (The tall boy plays.)
  • For girls: La chica alta juega. (The tall girl plays.)

Articles

• Definite Articles (the):
  • Use El for boys and La for girls.
• Indefinite Articles (a/an):
  • Use Un for boys and Una for girls.

Practice

• Match adjectives correctly:
  • Los perros grandes (The big dogs - boys).
  • Las gatas grandes (The big cats - girls).

By following these rules, you can change adjectives to match whether you're talking about boys or girls in Spanish!
