Direct Object Pronouns in Spanish
Direct objects are nouns which receive the action of a verb in a sentence. Direct object pronouns replace that noun (and also noun phrases and nominalized clauses). Just like personal (subject) pronouns replace the subject noun in a sentence, direct object pronouns replace the direct object noun in a sentence, which can be a person or a thing.
Direct Object Pronouns
|1st person||me (me)||nos (us)|
|2nd person||te (informal you)||os (informal you)|
|3rd person||lo, la (it, him, her, formal you)||los, las (them, formal you)|
The direct object of a sentence can be an object.
In the sentences below, la pelota receives the action of tiró, and thus is the direct object of the sentence. It is singular and feminine, and since it represents an inanimate object, it is in the 3rd person; therefore, you can replace it with the direct object pronoun la.
In the next example, muchos libros receives the action of leen. It is plural, masculine, and 3rd person, so it can be replaced with the direct object pronoun los.
