Navigating the nuances of English grammar can often feel like walking through a minefield, especially when it comes to the simple yet perplexing question of when to use is or are. These two verbs are the building blocks of communication, yet they cause more confusion than almost any other aspect of subject-verb agreement. Whether you are crafting a professional email, writing an academic essay, or simply chatting with friends, choosing the wrong form can alter the meaning of your sentence or make your writing appear unpolished. The core rule relies heavily on the concept of plurality, but as with many English language rules, there are exceptions and complex scenarios that require a deeper look.
Understanding the Basics of Subject-Verb Agreement
At its most fundamental level, the decision between is and are boils down to whether your subject is singular or plural. "Is" is a form of the verb "to be" used exclusively with singular subjects, while "are" is used with plural subjects. This sounds straightforward until you encounter collective nouns, compound subjects, or indefinite pronouns that seem to defy these simple categorizations.
To master this, you must first identify the subject—the person, place, or thing performing the action or being described. If that subject represents only one unit, reach for "is." If it represents more than one, reach for "are."
- Singular: The cat is sleeping on the sofa.
- Plural: The cats are sleeping on the sofa.
When To Use Is Or Are With Collective Nouns
One of the most frequent points of confusion regarding when to use is or are arises when dealing with collective nouns. These are words that refer to a group of people or items acting as a single unit, such as team, family, committee, or herd. In American English, collective nouns generally take a singular verb because the group is viewed as one entity.
However, if the members of that group are acting individually and independently, you might choose to use the plural form to emphasize that diversity of action. This is where context becomes your best guide.
| Subject Type | Verb Selection | Example |
|---|---|---|
| Singular Subject | Is | The committee is meeting at noon. |
| Plural Subject | Are | The committee members are arguing about the policy. |
| Compound (Joined by "and") | Are | The pen and the paper are on the desk. |
💡 Note: When using "or" or "nor" to join subjects, the verb should agree with the subject closest to it. For example, "Neither the teacher nor the students are in the room."
Navigating Indefinite Pronouns
Indefinite pronouns like each, everyone, anybody, and neither can be tricky. Even though "everyone" sounds like it involves a crowd, it is grammatically treated as a singular unit. Therefore, you should almost always use "is" with these terms. Conversely, words like both, few, and many are inherently plural and demand the use of "are."
Consider these examples to help clarify:
- Everyone is invited to the party.
- Both of the candidates are qualified for the position.
- Each of the flowers is blooming this season.
The Role of Prepositional Phrases
A common mistake occurs when a prepositional phrase sits between the subject and the verb. Many writers mistakenly make the verb agree with the noun inside the prepositional phrase rather than the actual subject. Remember that the verb must always agree with the true subject of the sentence, regardless of what words follow it.
For example, in the sentence, "The box of ornaments is on the shelf," the subject is "box," not "ornaments." Because "box" is singular, "is" is the correct choice. If you write "are" because your eye is drawn to the word "ornaments," you have fallen into a common trap. Always strip away the extra phrases to find the core subject.
Determining Agreement in Sentences Beginning With "There"
When a sentence begins with "there," the subject follows the verb. This is known as an inverted sentence structure. To determine whether to use is or are, you must look ahead to the noun that follows the verb. If that noun is plural, use "are." If it is singular, use "is."
This is frequently misunderstood in spoken English, where people often default to "there's" regardless of what follows. In formal writing, however, precision is paramount:
- There is a single apple left in the bowl.
- There are many reasons to visit the city.
💡 Note: Be cautious with contractions like "there's." While acceptable in casual conversation, it effectively means "there is," so avoid using it if the following subject is plural.
Final Thoughts on Subject-Verb Mastery
Mastering the distinction between these two verbs is less about memorizing endless rules and more about training your ear to hear the rhythm of correct grammar. Start by consistently identifying your subject, being mindful of collective nouns, and ignoring distracting prepositional phrases. By taking a moment to analyze the plurality of your sentence, you will find that the choice between is and are becomes second nature. Practice these rules in your daily writing, and you will soon notice an improvement in the clarity and authority of your communication. The precision you bring to these small details reflects a higher standard of literacy and attention to detail that is always appreciated by readers.
