Indefinite Pronouns

Treat agreement by the actual pronoun, not by a blanket “all indefinite pronouns are singular” rule. Forms such as “everyone” are singular for verb agreement, while other indefinite pronouns can be plural or vary with meaning; register also affects choices such as “somebody” versus “someone.”

Quick answer

Indefinite pronouns refer to people, things, amounts, or places without naming a specific one: “someone,” “anybody,” “nothing,” “everyone,” and related forms. Many -one/-body/-thing pronouns take singular verb agreement, but indefinite pronouns do not all behave identically.

Further guidance

Agreement

Use singular agreement with common forms such as “everyone” and “nothing.” Check other indefinite pronouns individually because forms such as “many” and “several” pattern differently.

Recognize

Look for forms that refer without identifying a particular person or thing, such as “someone,” “anything,” “everybody,” or “nowhere.”

Reference

Choose a following pronoun that keeps the reference clear. Singular “they” is widely used after indefinite antecedents when gender is unknown or irrelevant.

Worked Example

“Everyone is ready, and they have their tickets” uses singular verb agreement with “everyone” and singular “they” for later reference.

Personal Pronouns

Choose a personal-pronoun form by grammatical function, not by formality: subjects normally use forms such as “I” and “they,” while objects use “me” and “them.” Keep possessive and reflexive forms distinct, and make the intended antecedent clear.

Pronoun Agreement

Pronoun agreement and pronoun reference are related but distinct editing checks. Agreement asks whether forms match appropriately; reference asks whether the antecedent is clear and unambiguous.
