Which possessive pronoun correctly fills the blank: "_____ daughter is five years old"?

In the sentence "_____ daughter is five years old," the appropriate possessive pronoun is one that indicates ownership or relationship to the noun "daughter."

While "our" is commonly used to indicate something belonging to a group including the speaker, in this context, “their” indicates possession in a more general sense that allows for an unspecified subject who is not directly indicated as part of the speaker's group. This makes it a less suitable choice in a context where the speaker seems to have a direct connection to the daughter.

When choosing a pronoun, it’s important to ensure it aligns with the context of the sentence. It suggests the relationship of the possessor to the daughter being mentioned, which is why "her" closely links to a specific female possessor. However, in this case, since "their" can refer to the possessor in a general or collective way, it could also be suitable depending on the broader context of prior discussion.

Ultimately, understanding the context and the relationships indicated by possessive pronouns is essential for filling in the blank correctly.
