A plural verb is used with pronouns at once, few, many and several, which are always plural: Singlar`s indeterminate pronouns contain the bonds of -body, -one and -thing, with the words one, one another, each, either, neither and many. A singular verb is used with these pronouns: pronouns like everyone else, more, none, and some take their meaning from the word to which they refer (which is often found in a sentence after the pronoun): it is important to know whether a pronoun subject is singular or plural so that we can accept the verb. Undetermined pronouns are non-specific words like someone, others, several or none. Some of these pronouns are always singular or always plural. However, some may change their number – they can be either singular or plural depending on the context.
