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.
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'.
