Indefinite pronouns refer to unspecific people or things. The following indefinite pronouns are all grammatically singular, even if some of them seem to have a plural meaning:

what I am talking about.

Each of my family members are that way — except me.

that way — except me.

Note that when each follows a plural pronoun or noun, it is not an indefinite pronoun but a modifier, and the verb should be plural.

Note that when neither is paired with nor — as in “Neither my mother nor my brothers ask for help” — these words are not indefinite pronouns but conjunctions joining alternative subjects. The number of the verb should match the number of the subject closer to the verb.
