Error in Pronoun Agreement
Pronouns should agree with their antecedents (the word to which the pronoun refers). The following indefinite pronouns should be treated as singular:
anybody, anyone, each, either, everybody, everyone, everything, neither, none, no one, someone, something.
Everybody has his or her opinion.
To avoid the clumsiness of his or her, rephrase the sentence like this:
We all have our own opinions
THE RULE: Pronouns must agree with their antecedents in gender and in number.
Explanation:
This rule means that—
• singular antecedents require singular pronouns;
• plural antecedents require plural pronouns;
• a masculine antecedent requires a masculine pronoun;
• a feminine antecedent requires a feminine pronoun; and
• an antecedent that may be masculine or feminine requires a non-sexist pronoun (such as the he or she combination).
Proofreading Tip 1: Watch Out for THEY, THEM, or THEIR!
If you find the word they, them, or their in your writing, WATCH OUT! Make sure that this plural pronoun does actually refer to a plural antecedent. It should not refer to singular antecedents when no gender is specified.
Error: When a student attends a local college, they can live quietly and inexpensively at home.
Discussion: Student is singular, but they is plural. Also, a student can be either male or female.
Correction: When a student attends a local college, he or she can live quietly and inexpensively at home.
