2. Pronoun – Antecedent Agreement
A pronoun is a word that takes the place of a noun.
An antecedent is the noun to which the pronoun refers.
Pronouns must agree with their antecedents in number and gender.

3. Troubleshooting: Indefinite Pronouns
Indefinite pronouns refer to nonspecific persons or things.
Even though many indefinite pronouns seem plural, they are treated as singular in standard written English.
Indefinite Pronouns: anybody, anyone, anything, each, either, everybody, everyone, everything, neither, nobody, no one, somebody, someone, something

4. Troubleshooting: Indefinite Pronouns
Incorrect: Everyone is responsible for their learning.

Correct: All students are responsible for their learning.
Correct: One is responsible for one’s own learning.
Correct: The responsibility for learning falls squarely on the shoulders of the student.

5. Troubleshooting: Generic Nouns

Treat generic nouns as singular, and use singular pronouns in reference to generic nouns.

6. Troubleshooting: Generic Nouns
Incorrect: A circus clown must be both frightening and funny if they are to be successful on the carnival circuit.
Here, the generic noun a circus clown is incorrectly referred to with a plural pronoun.
Correct: Circus clowns must be both frightening and funny if they are to be successful on the carnival circuit.

7. Troubleshooting: Collective Nouns
Collective nouns name a class or group.
Most of the time, the group functions as a unit, and so should be treated as singular.
If, however, the members of the group are acting as individuals, treat the collective noun as plural.

8. Collective Nouns as a Unit
Incorrect: The jury gave their verdict to the judge.
Here, the jury is acting as a unit; therefore, the plural pronoun their is not appropriate.
Correct: The jury gave its verdict to the judge.

9. Collective Nouns as Individuals
Incorrect: The jury groaned when it was told it would be sequestered.
It’s not probable that the jury groaned in unison; rather, each member probably groaned individually. So, the singular pronoun it isn’t correct.
Correct: The jury groaned when they were told they would be sequestered.

10. Troubleshooting: Compound Antecedents
Treat compound antecedents joined with and as plural
Example: When Kim and Tim get phone calls, they sometimes have a difficult time discerning for whom the caller is asking.
Kim and Tim is a compound antecedent joined with and, so the plural pronoun they is appropriate.

11. Troubleshooting: Compound Antecedents
Compound antecedents joined with or or nor should use a pronoun that agrees with the nearer antecedent.
Example: Either Amy or Julie will loan her purse to Cassi.
Example: Neither the President nor the advisors could make their speeches coherent.

12. Troubleshooting: Compound Antecedents
When one antecedent is male and the other female, do not use a gender-specific pronoun. It won’t make sense.

The best solution is to recast the sentence to avoid the problem.
Correct: A prize for hard work on the project should go to either Kim or Tim.
