The verb following there is singular or plural according to the number of the
subject that follows the verb: There is a message for you. There are patients
in the waiting room. With compound subjects in which all the coordinate words
are singular, a singular verb often occurs, although the plural may also be
used: There was (or were ) a horse and a cow in the pasture. When a compound
subject contains both singular and plural words, the verb usually agrees with
the subject closest to the verb, although a plural verb sometimes occurs
regardless, especially if the compound has more than two elements: There were
staff meetings and a press conference daily. There was (or were ) a glass,
two plates, two cups, and a teapot on the shelf.
