An indirect object is a person that someone or something does something to indirectly. In the simplest sentences, the indirect object directly follows a verb + preposition, so it’s very easy to see the effect that the verb has on that person.
Who, what, which one? Use interrogative pronouns to ask these questions, which are a little more complicated in Spanish than in English.
Lo is the Spanish neuter direct object pronoun, used to mean "it" when referring to something non-specific or with no gender, such as an idea, adjective, situation, or clause.
Spanish negative pronouns (nada, nadie, ninguno) negate, refuse, or cast doubt on the existence of the noun that they replace.
Object pronouns (direct, indirect, and reflexive) usually precede the verbs they modify. However, in the case of infinitives, gerunds, and affirmative commands, they often get attached to the end of the verb instead.
Possessive pronouns are the words which replace nouns modified by possessive adjectives. In Spanish there are different forms of possessive pronouns depending on whether the noun is masculine or feminine, singular or plural.
Spanish prepositional pronouns are used after prepositions, logically enough, often in order to emphasize the noun they replace, and are thus a sort of subcategory of the disjunctive or stressed pronouns found in other languages.
Que is the simplest and most common Spanish relative pronoun. Depending on context, the English equivalent can be "who," "whom," "that," or "which."
The relative pronoun quien joins a main clause to a dependent or relative clause, replaces one or more words, and can only refer to people. The plural form is quienes.
In Spanish, you will often see an object pronoun, either direct or indirect, used in addition to the actual noun that it would normally replace. This redundant object pronoun may be required or simply stylistic.
