Subject-verb agreement is a vital aspect of English grammar. It refers to the proper alignment between the subject and the verb in a sentence. Correlative conjunctions, like most grammatical structures, can complicate subject-verb agreement. Thus, it is essential to have a strong grasp of the rules that govern this aspect of English grammar.

Correlative conjunctions are used to connect two parts of a sentence that have equal importance. Some examples of correlative conjunctions include `both…and,` `either…or,` `neither…nor,` `not only…but also,` and `whether…or.` These structures help to add variety and clarity to the content of a sentence.

When using correlative conjunctions, it is important to consider the agreement between the subject and the verb. The rule of subject-verb agreement states that the verb used in a sentence should always agree with the subject. This means that if the subject is plural, the verb should also be plural. If the subject is singular, the verb should also be singular.

For example, ”Both Sarah and John are going to the party” is an example of subject-verb agreement. The subject, ”Sarah and John,” is plural, and so the verb, ”are,” is also plural. Conversely, in the sentence ”Either the cat or the dog is at the door,” the subject, ”the cat or the dog,” is singular, so the verb, ”is,” is also singular.

However, when using correlative conjunctions, it is easy to make mistakes. Consider the sentence, ”Not only the cat but also the dogs are noisy.” In this example, the verb, ”are,” incorrectly agrees with the second subject, ”dogs,” instead of with the singular subject, ”cat.” The correct version of this sentence should read, ”Not only the cat but also the dogs are noisy.”

Another common mistake is using a singular verb when the subject is plural. For example, the sentence ”Both the cats and the dog is sleeping” is incorrect because the verb, ”is,” is singular, whereas the subject, ”the cats and the dog,” is plural. The correct version of this sentence is ”Both the cats and the dog are sleeping,” with the plural verb, ”are,” matching the plural subject.

In conclusion, correlative conjunctions can add style and structure to your writing, but it is critical to ensure that the subject and verb in your sentence agree. By following the rules of subject-verb agreement, you can avoid common mistakes and ensure that your writing is clear and concise. As a professional, it is essential to have a strong grasp of grammar to deliver high-quality content that resonates with your readers.
