The UVic Writer's Guide Pronoun Agreement Pronouns agree in gender and number. However, collective pronouns present more of a problem. Indefinite words such as anyone, anything, someone, everybody and no one take singular pronouns.
Pronouns are also an issue when using gender-specific language.
The antecedent is the noun to which the pronoun refers. Also, make sure that you are referring to the correct noun. Be aware of the case of the pronoun. Use I in the subjective case and me in the objective case, no matter what other pronouns are found in the sentence. More information is available in the discussion of agreement as a grammatical issue.
