Usage Note: In standard usage, the subject of a sentence beginning with each is grammatically singular, and so the verb and following pronouns must be singular: Each of the apartments has (not have) its (not their) own private entrance (not entrances). When each follows a plural subject, however, the verb and subsequent pronouns remain plural: The apartments each have their own private entrances (not has its own private entrance). When each follows the verb, it has been traditionally considered acceptable to say either The boys have each their own bike or The boys have each his own bike, though both of these (and especially the latter) are likely to seem stilted in comparison to The boys each have their own bike or The boys each have their own bikes. · The expression each and every is likewise followed by a singular verb and singular pronoun: Each and every driver knows (not know) what his or her (not their) job is to be. This expression is sometimes criticized as redundant, and so it is, but it emphasizes both the universality and individuality of the collection being discussed, much like every single one. See Usage Notes at every, they.
