Indefinite Pronouns

These pronouns can be used in a couple of different ways:

  • They can refer to members of a group separately rather than collectively. (To each his or her own.)
  • They can indicate the non-existence of people or things. (Nobody thinks that.)
  • They can refer to a person, but are not specific as to first, second or third person in the way that the personal pronouns are. (One does not clean one’s own windows.)

Please note that all of these pronouns are singular. The table below shows the most common indefinite pronouns:

anybody anyone anything each either every
everybody everyone everything neither no one nobody
nothing nobody else somebody someone something  one

Note: Sometimes third-person personal pronouns are sometimes used without antecedents—this applies to special uses such as dummy pronouns and generic they, as well as cases where the referent is implied by the context.

  • You know what they say.
  • It’s a nice day today.

Please note that all of these pronouns are singular. Look back at the example “To each his or her own.” Saying “To each their own” would be incorrect, since their is a plural pronoun and each is singular. We’ll discuss this in further depth in Antecedent Agreement.


Identify the indefinite pronouns in the following sentences. Is the best indefinite used, or is there another indefinite that would fit better?

  1. Everyone should take the time to critically think about what he or she wants out of life.
  2. If I had to choose between singing in public and swimming with leeches, I would choose neither.
  3. Yasmin knew everything was wrong, but she couldn’t figure out what.
  4. If nobody else enrolls in this class, it will be cancelled this semester.
