In Spanish, adjectives are words that describe nouns. They must match the nouns in two ways: gender (male or female) and number (singular or plural). Here are some simple rules to help you understand how this works:

Gender Agreement

1. Masculine and Feminine:
   • Most adjectives for masculine nouns end with -o.
     • For example, niño alto means "tall boy."
   • Most adjectives for feminine nouns end with -a.
     • For example, niña alta means "tall girl."
   • Exceptions: Some adjectives stay the same for both genders.
     • For example, inteligente means "intelligent" for both boys and girls.

Number Agreement

1. Singular and Plural:
   • To make adjectives plural, add -s if the word ends with a vowel.
     • For example, niños altos means "tall boys."
   • If the adjective ends with a consonant, add -es.
     • For example, mujeres inteligentes means "intelligent women."

Examples

• El gato negro (The black cat - masculine).
• La casa blanca (The white house - feminine).
• Los perros grandes (The big dogs - plural masculine).
• Las flores hermosas (The beautiful flowers - plural feminine).

By learning these rules, you'll get better at writing and speaking in Spanish!
