Subject Pronouns in Spanish | Chart & Examples

Published on January 17, 2025 by Kate Santoro, BS. Revised on December 2, 2025

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 December 2, 2025

The direct object pronouns in Spanish are โ€œme,โ€ โ€œte,โ€ โ€œlo,โ€ โ€œla,โ€ โ€œnos,โ€ โ€œos,โ€ โ€œlos, and โ€œlas.โ€

Like in English, a direct object in Spanish is a noun that receives the action of the verb. Itโ€™s usually an object or person and answers the question โ€œwhat?โ€ or โ€œwhom?โ€

For example, in โ€œJohn buys a car,โ€ โ€œcarโ€ is the direct object, as it receives the action of โ€œbuying.โ€ We could also rephrase this as โ€œJohn buys it,โ€ where โ€œitโ€ is a pronoun.

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

Direct object pronouns in Spanish examples

Spanishย  Englishย  Spanishย  Englishย 
Marรญa compra una falda. Marรญa buys a skirt. Marรญa la compra. Marรญa buys it.
