This document discusses demonstrative adjectives in Spanish. It explains that demonstrative adjectives point out specific nouns and must agree in number and gender with the noun. There are three types: este/esta/estos/estas point to things near the speaker, ese/esa/esos/esas point to things farther away, and aquel/aquella/aquellos/aquellas point to things at a great distance. It also notes that demonstratives can function as pronouns by replacing nouns while maintaining the same number and gender, with an accent over the "e".
