* Third-person: It refers to someone or something other than the speaker (I) or the person being spoken to (you).
* Singular: It refers to one person, not multiple people (they).
* Personal: It's a pronoun that refers to a person (or sometimes an animal or object personified).
Its grammatical function is to act as a noun phrase; it stands in for a noun (a person's name) in a sentence. It can be the subject of a verb, the object of a verb, or the object of a preposition.
For example:
* Subject: She went to the store.
* Object: I saw her.
* Object of a preposition: The gift is for her.
