Demonstrative Pronouns

Demonstrative pronouns (this one, that one, the one[s], these, those) refer to a previously-mentioned noun in a sentence. Spanish demonstrative pronouns are more complicated than their English counterparts, because there are three different sets and because they must agree in gender and number with the noun they replace.

Indefinite Pronouns

Pronombres indefinidos

Spanish indefinite pronouns, sometimes called affirmative indefinite pronouns, are unspecific and are used in place of nouns. They can be the

subject of a sentence object of a verb object of a preposition Todo el mundo está aquí.   Everyone is here. Compró algo.   He bought something. Tengo un regalo para alguien.
