Subject Pronouns in Spanish | Chart & Examples

Published on January 17, 2025 by Kate Santoro, BS

The subject pronouns in Spanish vary based on number, person, gender, and intended formality.

Pronouns replace nouns, and subject pronouns replace nouns that act as subjects, performing the action of the sentence. These differ from direct object pronouns, which replace the direct object (and receive the action in the sentence).

Just like in English, subject pronouns are different from direct object pronouns in Spanish.

Direct Object Pronouns in Spanish | Use & Examples

Published on January 13, 2025 by Kate Santoro, BS Revised on January 28, 2025

The direct object pronouns in Spanish are “me,” “te,” “lo,” “la,” “nos,” “os,” “los, and “las.”

Like in English, a direct object in Spanish is a noun that receives the action of the verb. It’s usually an object or person and answers the question “what?” or “whom?”

For example, in “John buys a car,” “car” is the direct object, as it receives the action of “buying.” We could also rephrase this as “John buys it,” where “it” is a pronoun.

We can replace direct object nouns with direct object pronouns in Spanish, too.

Direct object pronouns in Spanish examples
