Match a masculine pronoun with a masculine antecedent and a feminine pronoun with a feminine antecedent so that the pronoun and its antecedent agree in gender.
If an antecedent might be either masculine or feminine, avoid using a pronoun that stereotypes by gender. (See also W3-c.)
Match a plural antecedent with a plural pronoun to include both sexes.
Use a phrase that includes both masculine and feminine singular pronouns (such as his or her) to refer to both sexes.
Note: If repeating a phrase such as his or her seems cumbersome or repetitious, try using plural forms or eliminating the pronouns altogether, as the following strategy suggests.
Eliminate unneeded or awkward pairs of masculine and feminine pronouns.
Note: Avoid using he/she in all but the most informal writing situations.
