"Indefinite Pronouns are used when sentence does not refer to any specific person, thing or amount. Indefinite pronouns are words like a few, some, several, any, most, other, some, each, everything, none, neither and either."

Most indefinite pronouns are either singular or plural. However, some of them can be singular in one context and plural in another.

	Singular	few, little, anyone, each, another, anybody, something, everybody, much, nobody, nothing, one, no-one, other, neither and either.
	Plural	many, fewer, others, several, both, everything
	Singular or Plural	some, any, all, more, most, none, such

Note: A singular pronoun takes a singular verb AND that any personal pronoun should also agree. Similarly, plural pronouns need plural agreement:

These pronouns apply in general to people and things and not to any particular person/things. They are: All, Any, Another, Anybody, Both, Few, A few, Little, A little, Many, Much, None, No-one, One, Other, The others, Several.
