Indefinite adjective vs indefinite pronoun

Most of the words in the list above can function as both an adjective and a pronoun. As a pronoun, they don’t take a noun after them and stand alone.

  • I bought a lot of new pants last month for charity. I still have some with me. (indefinite pronoun)
  • We are looking for some writers. (indefinite adjective)
  • Thousands of people joined the protest in the morning at the TED Mall. Many of them are still there. (indefinite pronoun)
  • I gave him many ideas to get rich. (indefinite adjective)
  • There were over 200 guests. Several of them are still in the hall.
  • Several people were fired last month.
  • You can eat this. I have more.
  • Give me more water.

Notice that when these words function as an adjective, they have a noun after them that they modify. And when they function as a pronoun, they refer to a noun and stand alone. The nouns that the indefinite adjectives modify in these examples are underlined.

Not all indefinite pronouns can function as indefinite adjectives

  • Someone
  • Something
  • Anyone
  • Anything
  • Everyone
  • Everything
  • No-one
  • Nothing

Examples:

  1. Someone came to see you at the office an hour ago.
  2. I have everything that I need.
  3. Nothing is impossible.

These are words that function as indefinite pronouns; they don’t function as adjectives. Don’t consider them an indefinite adjective.
