Personal Pronoun - Subject I you he/she/it we they
Personal Pronoun - Object me you him/her/it us them


The personal pronoun is used to refer to someone or something already mentioned (he, she, it etc.), or to refer to the person speaking (I, me etc.) or the person listening (you).


I, me, he, she, him, her, you = a person

you, we, us = people

it = thing

they, them = things or people

The possessive pronoun shows who the thing being referred to belongs to or is associated with. In English these pronouns change form to show their function.

You(singular and plural) yours
He/She/It his/hers/its
We ours
They theirs



First Person Pronoun  
Singular mine
Plural ours
Second Person Pronoun  
Singular yours
Plural yours
Third Person Pronoun  
Singular his, hers, its

For example:

Q. Whose is this web site?

A. It's mine.

Q. Does Lynne own this web site?

A. Yes, it's hers.

Q. Does Lynne own the Internet?

A. No. It's ours.


My, your, his/her/its, our and their are possessive determiners(sometimes called possessive adjectives).

Watch out for the following:-

Possessive Pronoun Short Form of 'it is'
its (no apostrophe) it's (with apostrophe)


Indefinite pronouns refer to things or people without mentioning what or who they are.

Singular: another, anybody, anyone, anything, each, either, everybody, everyone, everything, little, much, neither, nobody, no one, nothing, one, other, somebody, someone, something
Plural: both, few, many, others, several
Singular or Plural all, any, more, most, none, some

For example:

Somebody stole my car.

Does anybody know who she is?

Does anyone have something that could help me with anything?


For people we use: anybody or anyone | somebody or someone | nobody or no one.
For things we use: anything, something, nothing, none.
