The Forms of Personal Pronouns

The form of a personal pronoun shows how it can be used in a sentence. Pronouns used as subjects and predicate nominatives are in the subject form.

Examples: 

He and I went to the post office.

The winner of the marathon is she.

Pronouns used as direct objects and indirect objects of verbs and objects of the preposition are in the object form.

Examples:

The clerk gave us the package.

when is Theo going to give the flowers to her?
