'We took the horses out by ourselves.'
In English, personal pronouns are used instead of nouns for 'people' and 'things'.
They are used so that we don't repeat the same words over and over again. Let's look at an example using the noun picture:
Both I and me are personal pronouns.
I is a subject prounoun and it's used for the subject of the sentence. He, she, we, it, they and you are also subject pronouns.
"Hugo and I work in the same office" - 'Hugo and I' are the subject.
'This is her' or 'This is she'?
His and hers are possessive pronouns. They are used to substitute a noun and to show possession or ownership.
Example: This hat is hers.
