There are indefinite pronouns that are always singular (anyone, nobody, somebody, etc) and there are also indefinite pronouns that are always plural (both, others, several, etc). A small number of indefinite pronouns can be singular or plural: all, any, more, most, none, and some. Here are examples of how they are used.

Examples:

  • All he needs now is a $1,000 loan. (= The only thing he needs now is a $1,000 loan. All is used as a singular.)
  • All were arrested for fighting. (= Everyone {involved in the fighting} were arrested. All is a plural here.)
  • Is there any of your home-made soup left?. (Any is singular as it is used with an uncountable noun.)
  • Are any of you going to help find my missing car keys? (Any is plural, used with second person you.)
  • Some people have volunteered for the rescue but more are needed.
  • He accidentally spilled his coffee; more was spilled on my shirt.
  • Most have joined the campaign after listening to his talk.
  • Most of her money is spent on clothes.
  • They have drunk all the orange juice, and there is none left for me.
  • After what happened, none of her friends phone her anymore.
  • Some of the wine we had after lunch was very good.
  • Some of you have not understood what I said.
