Origin of either
As an adjective either refers only to two of anything: either side of the river; using either hand. As a pronoun either sometimes occurs in reference to more than two ( either of the three children ), but any is more common in this construction ( any of the three children ). As a conjunction, either often introduces a series of more than two: The houses were finished with either cedar siding or stucco or brick. The pizza is topped with either anchovies, green peppers, or mushrooms.
Usage guides say that the verb used with subjects joined by the correlative conjunctions either … or (or neither … nor ) is singular or plural depending on the number of the noun or pronoun nearer the verb: Either the parents or the school determines the program. Either the school or the parents determine the program. Practice in this matter varies, however, and often the presence of one plural, no matter what its position, results in a plural verb: Either the parents or the school determine the program.
In carefully edited writing, these correlative conjunctions are usually placed so that what follows the first correlative is parallel to what follows the second: The damage was done by either the wind or vandals or either by the wind or by vandals (not done either by the wind or vandals). See also neither.
