indefinite Pronouns

What are Indefinite Pronouns?

As the name suggests indefinite pronouns are pronouns that are not definite in meaning. In other words they are not specific in which noun they replace. They may be singular or plural, and must match the verb in number.
There are two categories of indefinite pronouns. The first category includes pronouns that refer to a nonspecific noun. These pronouns are:

anybody	anyone
anything	everybody
everyone	everything
nobody	none
no one	nothing
somebody	someone
something

Example:

Anything is possible if you believe.

The second category of indefinite pronouns are those that point to a specific noun whose meaning is easily understood only because it was previously mentioned or because the words that follow the indefinite pronoun make it clear. These pronouns are:

all	another
any	both
each	either
few	many
neither	one
some	several

Examples:

Many are planning to attend the party. (In this case the identity of the group that is going to the party would have already been mentioned.)
Would you like to try some of these cookies? (The word cookies makes it clear what some is referring to.)

Not to confuse you but keep in mind the pronouns in this group can function as adjectives if nouns directly follow them.
More Examples:

Many classmates are planning to attend the party.
I checked out some books from the library.
