When it comes to writing, one of the most important aspects is ensuring proper subject-verb agreement. However, this can become even more complex when helping verbs are involved. Helping verbs, also known as auxiliary verbs, are added to the main verb to create various tenses, moods, and voices. Therefore, it is crucial to understand how to use them correctly in combination with subject-verb agreement.

To start, let`s review what subject-verb agreement entails. In essence, this rule dictates that a singular subject must have a singular verb, while a plural subject must have a plural verb. For example:

– Singular: The dog barks loudly.

– Plural: The dogs bark loudly.

Simple enough, right? But what happens when we add in helping verbs? This is where the potential for errors increases. Here are a few examples:

– Singular: She has eaten breakfast.

– Plural: They have eaten breakfast.

In both cases, the helping verb “has” and “have” agree with their respective subjects. Similarly:

– Singular: He is running late.

– Plural: They are running late.

Again, the helping verb “is” and “are” fit with their respective subjects. The key is to always ensure that the helping verb agrees with the subject in terms of singular or plural status.

But what about more complex situations? Let`s take a look at a few examples:

– Singular: The team of doctors is preparing for surgery.

– Plural: The groups of students are studying for exams.

In these examples, the subjects are no longer simple singular or plural nouns, but rather noun phrases. However, the same rule applies – the helping verb must agree in terms of singular or plural status with the overall subject. In the first sentence, “team” is singular, so “is” is used. In the second sentence, “groups” is plural, so “are” is used.

Finally, sometimes a sentence can become confusing when a prepositional phrase or dependent clause is added in between the subject and verb. However, it`s important to remember that these additions do not affect subject-verb agreement; it`s still determined based on the overall subject. For example:

– Singular: The book on the shelf belongs to me.

– Plural: The books on the shelves belong to me.

In both cases, the prepositional phrase “on the shelf” and “on the shelves” do not affect the subject-verb agreement, as the subjects are still singular and plural respectively.

In conclusion, understanding subject-verb agreement with helping verbs is crucial for clear and effective writing. By keeping in mind that the helping verb must agree with the overall subject in terms of singular or plural status, you can ensure that your writing is grammatically correct and easy to understand.
