`
`[Middle English , from other, or (from Old English , from oththe) and from outher (from Old English
`āhwæther, āther ; see either).]
`
`Usage Note: When all the elements in a series connected by or are singular, the verb they govern is
`singular: Tom or Jack is coming. Beer, ale, or wine is included in the charge. When all the elements are
`plural, the verb is plural. When the elements do not agree in number, some grammarians have suggested
`that the verb should agree in number with the nearest element: Tom or his sisters are coming. The girls or
`their brother is coming. Cold symptoms or headache is the usual first sign. Other grammarians, however,
`have argued that such constructions are inherently illogical and that the only solution is to revise the
`sentence to avoid the problem of agreement: Either Tom is coming or his sisters are. The usual first sign
`may be either cold symptoms or a headache. See Usage Notes at and/or , either , neither , nor 1.
