* Example: "My friend is non-binary. They use the pronouns they/them."

* Example: "Someone left their phone in the classroom. They should contact the teacher."
4. Impersonal Pronoun: "They" can be used as a non-specific pronoun to refer to people in general, particularly in formal or impersonal contexts.
