aquéllos

Aquellos is a Spanish demonstrative adjective and pronoun that translates to "those" in English. It is used to point out people or things that are distant from both the speaker and the listener in space or time. Aquellos is the masculine plural form of the demonstrative adjective, agreeing in gender and number with the noun it modifies. For example, "aquellos libros" means "those books." As a pronoun, "aquellos" replaces a masculine plural noun, such as in the sentence "Me gustan esos, pero aquellos son mejores," meaning "I like these, but those are better." The feminine plural form is "aquellas."

The adjective "aquellos" is always used with a noun. When used as a pronoun, it stands alone and refers back to a previously mentioned or understood masculine plural noun. The choice between "aquellos" and other demonstratives like "estos" (these) and "esos" (those, near the listener) depends on the relative distance. "Aquellos" indicates the greatest distance. It is a fundamental word in Spanish grammar for establishing spatial and temporal relationships.
