The reflexive construction, used mainly with pronominal verbs, can also be used passively to describe accidental and unplanned occurrences. This is called la voz media in Spanish.
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.
A direct object is a noun, whether person or thing, that someone or something acts upon. In the simplest sentences, the direct object directly follows the verb, so it’s very easy to see the effect that the verb has on the noun.
The Spanish relative pronoun donde means “where” and is often preceded by a preposition.
A Spanish sentence can have both a direct object and an indirect object pronoun. These “double object pronouns” cannot be separated, and the indirect pronoun always precedes the direct pronoun.
The Spanish relative pronoun el cual usually means “who” or “whom” and has four different forms.
The Spanish relative pronoun el que usually means “who” or “whom” and has four different forms.
Ello is the Spanish neuter subject pronoun, used to mean “it” when referring to something non-specific.
Indefinite pronouns are vague – they either refer to unspecific nouns (like un otro and algo) or make sweeping generalizations (cada uno, todo).
There are about a dozen Spanish verbs which must be conjugated with an indirect object pronoun, such as gustar and importar. This grammatical construction does not exist in English, but it’s not difficult once you get used to it.
