What tells you that a sentence is written in the third person?

Here's how to identify a sentence written in the third person:

Look for these pronouns:

* He, she, it, they, him, her, them, his, hers, theirs. These pronouns refer to people or things that are not the speaker or the listener.

Examples:

* He went to the store.

* She is reading a book.

* They are playing in the park.

* It is raining outside.

Key Points:

* First person: "I" and "we" (the speaker)

* Second person: "You" (the listener)

* Third person: Everyone else (not the speaker or listener)

Exceptions:

* Impersonal "you" (You can see the ocean from here) - This is technically second person but functions like third person.

* "One" (One should always be polite) - This can also function like third person.
