Explanation:
Indefinite pronouns are useful to make reference to people or things withouht specifying their identity. There are two different word endings depending on what we want to talk about. Pronouns which end in -body or -one are implemented for people, whereas pronouns which end in -thing are destinated for things. Pronouns such as other, another and either are also indefinite pronouns. Finally, they are used both in plural and singular form depending on the case.
