Yes. All of these words are singular nouns, so you need a singular verb. Nobody has arrived. Does anyone know the answer? Everybody understands. That's the simple rule--> You can never use a plural verb form with any of these words. Here's the slightly more complicated bit. Even when we use 'they' as a pronoun, the words everybody, anyone and so on remain singular. Here are some examples: Nobody knows the answer, do they? Everyone has their books. Has everyone finished? Yes, they have.

Hi Mathias, What you are referring to are indefinite pronouns. They refer to general nouns -- they do not refer to specific things, animals, people etc. We form the indefinite pronouns you have listed by matching (A) to (B): (A) No / Some / Any (B) body / thing / one (Eg Nobody / Nothing / No one / Somebody / Something / Someone / Anybody / Anything / Anyone Some indefinite pronouns can refer to singular nouns while others refer to plural nouns. The ones you listed refer to singular nouns. Example: Has anyone seen my passport? No one was in the room when the police raided the place. Some examples of indefinite pronouns used with plural nouns are: Both and fewer Example: Both were found guilty and jailed. / Fewer were incarcerated for gang-related crimes this year. Some examples of indefinite pronouns used with BOTH singular and plural nouns are: More and Some. Example: We acquire more wisdom (uncountable) with age. / We need more more menus (countable)for the dinner crowd. Hope this helps. Cheers, Lance
