Spanish grammar: pronombres indefinidos

What this grammar point covers

Indefinite pronouns in Spanish are words used to refer to people or things in a non-specific way, like 'someone', 'something', or 'nobody'. They help you talk about things or people without saying exactly who or what.

When to use it

Use indefinite pronouns in Spanish when you want to talk about people or things in a general or unknown way. For example, when you don't know who did something, or when you mean 'some', 'any', 'none', or 'nothing'.

Key forms

• alguien
• nadie
• algo
• nada
• alguno/a/os/as
• ninguno/a

Examples

Tips

• Remember that some pronouns change for gender and number: 'alguno' (masculine singular), 'alguna' (feminine singular), 'algunos', 'algunas'.
• After a negative verb, use 'nada' (nothing) or 'nadie' (nobody).
• Be careful: 'ninguno' and 'ninguna' are usually singular, not plural.

Exceptions and edge cases

• When 'alguno' and 'ninguno' come before a masculine singular noun, they become 'algún' and 'ningún'.
