A pronoun is a word that takes the place of a noun. An indefinite pronoun takes the place of a noun, but an indefinite pronoun does not specify exactly which person or thing is being referred to. An indefinite pronoun acts as a singular noun and takes a singular verb.
I can help you with anything that you need.
Everything for dinner is on the counter.
I wish I had something to read.
There is nothing to do.
An indefinite pronoun replaces a noun, but the actual noun is unknown. Use a singular verb with an indefinite pronoun.
