Four important words you should learn in Spanish are algo (something), nada (nothing), alguien (someone) and nadie (no one). It’s really important to understand how to use these Spanish indefinite pronouns correctly in order to communicate effectively. In this article, we will explore the meanings, uses and examples of them. This will give you the knowledge you need to use these words accurately and confidently in your Spanish conversations.

Spanish Indefinite Pronouns

These Spanish indefinite pronouns are used to replace nouns and indicate the absence or presence of a particular thing or person. For example, no tengo nada means I have nothing, and quiero algo means I want something. Let’s learn now how to use them properly to communicate efficiently and concisely in various situations.

Algo (something)

Algo means something or anything and it is mainly used in affirmative or interrogative sentences.

¿Quiere algo para comer?

Do you want something to eat?

¿Hay algo en la bolsa amarilla?

Is there anything in the yellow bag?

Es demasiado caro. Busco algo más barato.

It’s too expensive. I’m looking for something cheaper.

Necesito hablar con ella de algo importante.

I need to talk with her about something important.

Alguien (someone)

Sometimes the specific person performing the action is either unknown or not specified. In those situations, you can use alguien, which means someone, somebody or anyone, anybody. For example, you can say alguien robó mi reloj (someone stole my watch).

¿Hay alguien en casa de Ana?

Is there anyone in Ana’s house?

Alguien está tocando la flauta.

Someone is playing the flute.

¿Alguien no está de acuerdo con la propuesta de Paula?

Does anyone disagree with Paula’s proposal?

Mi teléfono está sonando. Alguien está llamándome.

My phone is ringing. Someone is calling me.

Nada (nothing, anything)

Nada is the opposite of algo. It means nothing or anything. When used after a verb, you need to place no before the verb. That is called the double negation in Spanish and it is correct.

¿Necesitas algo? Yo no necesito nada.

Do you need anything? I don’t need anything.

El niño no tiene nada en los bolsillos.

The child doesn’t have anything in his pockets.

Yo traigo un regalo para tu nieta, ¿tú no traes nada?

I bring a present for your granddaughter, don’t you bring anything?

No digo nada porque no quiero problemas.

I don’t say anything because I don’t want trouble.

Nadie (no one, anyone)

Nadie is the opposite of alguien, so it means no one, nobody or anyone, anybody. When used after a verb, don’t forget to place no before the verb.

¿No hay nadie en casa? Hay alguien en casa, estoy segura.

Isn’t there anyone at home? There’s someone at home, I’m sure.

María no baila con nadie. Prefiere bailar sola.

María does not dance with anyone. She prefers to dance alone.

Sergio necesita un amigo. No habla nadie con él.

Sergio needs a friend. Nobody talks to him.

No conozco a nadie en esta ciudad porque no soy de aquí.

I don’t know anybody in this city because I’m not from here.

Double Negatives in Spanish

With the Spanish indefinite pronouns nada or nadie, you can create two different types of sentences. On one hand, you have the option of using a double negative by placing these Spanish indefinite pronouns after the verb. In this case, you should use no before it. On the other hand, you can place them before the verb, but then the verb should stay in affirmative. Compare the following examples.

No está nadie en clase.

Nadie está en clase.

No one is in class.

No estudia nadie en la biblioteca.

Nadie estudia en la biblioteca.

No one studies in the library.

No compramos nada en el mercado.

Nada compramos en el mercado.
