How do number and gender affect adjectives in the Spanish language? Write your answer in English. (4 points)
In the Spanish language, adjectives must agree in number and gender with the noun they modify. Number refers to whether the noun is singular or plural, and gender refers to whether the noun is masculine or feminine.
When an adjective modifies a singular masculine noun, it will typically end in -o. For example, "un libro interesante" (an interesting book). However, when that same noun is plural, the adjective must also be plural and change its ending to -os or -es. For example, "unos libros interesantes" (some interesting books).
When an adjective modifies a singular feminine noun, it usually ends in -a. For example, "una película emocionante" (an exciting movie). In the plural form, the adjective will change its ending to -as. For example, "unas películas emocionantes" (some exciting movies).
However, there are some exceptions to these general rules. Some adjectives have irregular forms, where the endings may change. Additionally, there are certain adjectives that are considered invariant, meaning they do not change regardless of the gender or number of the noun they modify.
