ESL: Pronoun-antecedent agreement

The pronouns he, his, she, her, it, and its must agree in gender (masculine, feminine, or neuter) with their antecedents (the words they refer to), not with the words that follow them.

Example sentence with editing. Original sentence: Elvis Presley had an unusually close bond with her mother. Revised sentence: Elvis Presley had an unusually close bond with his mother. Explanation: The word "her" has been replaced by "his."

Because the pronoun refers to the masculine noun Elvis Presley, the pronoun must also be masculine.
