Does or require plural or singular?

The Singular or Plural Quandary: Mastering Verb Agreement with “Or”

The humble conjunction “or” often causes confusion when it comes to subject-verb agreement. Unlike its counterpart “and,” which readily signals a plural subject, “or” presents a unique grammatical challenge. This stems from its inherent function: offering a choice between options, not a summation.

Consider the sentence structure: “The dog or the cat is sleeping soundly.” The verb “is” is singular, agreeing with “cat,” the noun closest to it. This is the key rule governing subject-verb agreement with “or”: the verb agrees with the noun or pronoun nearest to it.

This principle arises because “or” introduces alternatives. Only one of the options can be true at any given time. If the dog is sleeping, the cat is not; conversely, if the cat is sleeping, the dog is not. The sentence doesn’t describe a combined entity of a sleeping dog and cat, but rather presents two mutually exclusive possibilities. Therefore, the plural verb “are” would be grammatically incorrect.

Let’s examine some further examples:

• “The red shirt or the blue pants is on sale.” Here, “is” agrees with “pants,” the closest noun.

• “Neither the books nor the magazine is on the shelf.” “Is” agrees with “magazine.” Note that “neither…nor” follows the same rule as “or.”

• “Either the teacher or the students are responsible for the cleanup.” In this case, “are” agrees with “students,” the closer noun. This is a key exception to highlight; this specific case only follows the general “or” rule in the event of a singular noun. Plural nouns closest to the verb should use a plural verb.

The grammatical rule isn’t about proximity alone, however. It’s fundamentally about reflecting the exclusive nature of the choice presented by “or.” The sentence describes a single entity or action, not a combined one.

However, the rule takes a slightly different turn when the subject before “or” is plural. The verb is now in line with the closer noun, which will ultimately result in either a singular or plural verb. Consider the following example:

• “The students or the teacher is responsible for the cleanup.” The verb “is” agrees with the singular “teacher” even though the preceding noun is plural.

In conclusion, mastering subject-verb agreement with “or” hinges on understanding its function as a connector of mutually exclusive alternatives. The verb consistently agrees with the noun or pronoun immediately preceding it, reflecting the singular nature of the choice implied. While seemingly simple, this seemingly simple rule requires close attention to the specific nouns involved, particularly when dealing with plural nouns preceding the conjunction. Pay close attention to the noun closest to the verb – that’s the one that dictates the verb’s form.
