In Spanish, definite and indefinite articles are used to indicate the gender and number of a noun.
Definite articles: - “El” is used before masculine singular nouns. For example, “el libro” (the book). - “La” is used before feminine singular nouns. For example, “la casa” (the house). - “Los” is used before masculine plural nouns. For example, “los libros” (the books). - “Las” is used before feminine plural nouns. For example, “las casas” (the houses).
Indefinite articles: - “Un” is used before masculine singular nouns. For example, “un libro” (a book). - “Una” is used before feminine singular nouns. For example, “una casa” (a house). - “Unos” is used before masculine plural nouns. For example, “unos libros” (some books). - “Unas” is used before feminine plural nouns. For example, “unas casas” (some houses).
It’s important to note that Spanish articles also agree in gender and number with the noun they modify.
