In Spanish, adjectives (describing words) must match the nouns (names of people, places, or things) they describe.

This means they need to agree in two ways:

1. Gender (boy or girl)
2. Number (one or more)

Here are the Simple Rules for Agreement:

1. Masculine and Feminine:

   • Words for boys usually end in -o. For example, "niño" means "boy."
   • Words for girls usually end in -a. For example, "niña" means "girl."

2. Singular and Plural:

   • To make a word plural (more than one), if it ends in a vowel (like a, e, i, o, u), add -s.
   • If it ends in a consonant (like b, c, d, etc.), add -es.

Let’s look at the word "pequeño," which means "small":

• Singular Forms:

  • Masculine: niño pequeño (small boy)
  • Feminine: niña pequeña (small girl)

• Plural Forms:

  • Masculine: niños pequeños (small boys)
  • Feminine: niñas pequeñas (small girls)

Conclusion:

To change "pequeño" to fit with "niños":

• Change "pequeño" to pequeños by adding -s for the plural form.

You can also practice with other adjectives, like grande, which means "big":

• Niños grandes (big boys) and niñas grandes (big girls).

This is how you make sure all words work well together!
