What Are Subject and Verb Agreement?
Subject-verb agreement is a fundamental concept in English grammar that determines how verbs are formed based on the subject of a sentence. It ensures that the verb matches the subject in number (singular or plural) and person (first, second, or third). Mastering this rule is essential for creating clear, grammatically correct sentences that convey your intended meaning effectively. Whether you're writing an essay, crafting an email, or simply communicating in daily conversation, understanding subject-verb agreement helps avoid confusion and enhances your writing’s professionalism.
Understanding the Basics of Subject and Verb Agreement
Definition of Subject-Verb Agreement
Subject-verb agreement refers to the grammatical rule that requires a verb to agree in number and person with the subject of a sentence. In simpler terms, the verb must match the subject whether it is singular or plural. For example:
- Singular subject: The cat sleeps on the couch.
- Plural subject: The cats sleep on the couch.
Here, the verb "sleeps" is singular, matching "cat," while "sleep" is plural, matching "cats."
Why Is Subject-Verb Agreement Important?
Proper subject-verb agreement is critical for clarity and correctness. Without it, sentences can become confusing or grammatically incorrect. For instance:
- Correct: The dog barks at strangers.
- Incorrect: The dog bark at strangers.
The second sentence is grammatically flawed because the singular subject "dog" does not match the plural verb "bark." Such errors can weaken your message and make your writing appear unprofessional.
Identifying Subjects and Verbs
Before applying subject-verb agreement rules, it’s essential to identify the subject and verb in a sentence.
What Is a Subject?
The subject is the part of the sentence that performs the action or describes the state of being. It typically appears before the verb. For example:
- Subject: The teacher explains the lesson.
- Subject: Students enjoy learning.
What Is a Verb?
A verb is a word that shows action or state of being. Verbs change form based on tense and agreement. Examples include:
- Action verbs: run, write, jump
- Linking verbs: is, are, seems
Key Rules for Subject-Verb Agreement
1. Singular Subjects Take Singular Verbs
A singular subject (one person, animal, or thing) requires a singular verb. For example:
- Singular subject: The bird flies south for the winter.
- Singular subject: She watches TV every evening.
2. Plural Subjects Take Plural Verbs
A plural subject (multiple people, animals, or things) requires a plural verb. For example:
- Plural subject: The birds fly south for the winter.
- Plural subject: They watch TV every evening.
3. Compound Subjects Connected by “And” Take Plural Verbs
When two or more subjects are joined by “and,” the verb is typically plural. For example:
- Compound subject: The teacher and the student work together.
- Compound subject: Coffee and tea are available.
4. Subjects Connected by “Or” or “Nor” Follow the Verb of the Closest Subject
When subjects are connected by “or” or “nor,” the verb agrees with the subject closest to it. For example:
- With “or”: The teacher or the students are responsible.
- With “nor”: The students aren’t prepared, and the teacher isn’t either.
5. Indefinite Pronouns Like “Everyone,” “Everybody,” and “Each” Take Singular Verbs
Indefinite pronouns that refer to a single individual or group require singular verbs. For example:
- Singular verb: Everyone needs to study.
- Singular verb: Each student submits their homework.
6. Collective Nouns Can Be Tricky
Collective nouns (e.g., team, family, group) may take a singular or plural verb depending on context No workaround needed..
- Singular verb: The team wins the championship.
If the group acts individually, use a plural verb:
- Plural verb: The team argue about the strategy.
7. Titles and Phrases as Subjects
Titles of books, articles
Titles of books, articles, and movies are usually treated as singular, even when the title itself is plural That alone is useful..
- Singular verb: The Lord of the Rings is a famous novel.
- Singular verb: The Simpsons is a long-running animated series.
- Singular verb: The article titled “Five Ways to Save Money” explains budgeting basics.
If two or more titles are joined by “and,” use a plural verb:
- Plural verb: The Hobbit and The Lord of the Rings are both by J.R.R. Tolkien.
8. Intervening Words Do Not Change the Subject
Phrases between the subject and verb usually do not affect subject-verb agreement. Identify the true subject, not the nearest noun Worth knowing..
- The box of books is on the table.
- The students in the library are studying quietly.
- A list of supplies was posted near the door.
Words and phrases such as along with, as well as, together with, and together with do not create a compound subject:
- The coach, along with the players, is attending the meeting.
- The main idea, as well as the supporting details, needs revision.
9. “There Is” and “There Are”
In sentences beginning with “there is” or “there are,” the subject comes after the verb. Choose the verb based on the subject that follows Nothing fancy..
- There is a reason behind the decision.
- There are several reasons behind the decision.
- There was a delay caused by the storm.
- There were many delays caused by the storm.
10. Numbers, Fractions, and Amounts
Use a singular verb when a number or fraction is treated as one amount. Use a plural verb when the emphasis is on the individual parts.
- Singular amount: Ten dollars is enough for the ticket.
- Plural individuals: Ten students are waiting outside.
- Singular amount: Two-thirds of the pizza was eaten.
- Plural individuals: Two-thirds of the students were absent.
When a fraction or percentage is followed by a plural noun, a plural verb is often appropriate:
- Seventy percent of the respondents agree with the proposal.
When it refers to a singular or uncountable noun, use a singular verb:
- Seventy percent of the water was contaminated.
11. Relative Pronouns: “Who,” “Which,” and “That”
A verb in a relative clause agrees with its antecedent—the noun the pronoun refers to.
- The student who answers the question receives a prize.
- The students who answer the question receive prizes.
- The book that explains this topic is on the shelf.
- The books that explain this topic are on the shelf.
If the antecedent is an indefinite pronoun such as everyone, anyone, or no one, use a singular verb
12. Commas and Their Role in Coordinating Elements
Commas serve three primary functions: separating items in a list, setting off non‑essential information, and clarifying the pause needed before a coordinating conjunction. When you list three or more nouns, each item should be separated by a comma, but you omit the Oxford (or serial) comma before the final element if the list is short and clear. Take this: the professor, his assistant, and the intern all share the same role, so a single comma precedes “and Practical, not theoretical..
Non‑restrictive clauses—those set off by commas—provide extra detail that does not define the preceding noun. Think about it: * reads differently from, *The cat, which slept on the rug, purred loudly. In contrast, restrictive clauses are essential to the meaning and do not require commas. Writing, The cat that slept on the rug purred loudly. The second version emphasizes the cat’s location while the first simply adds background information.
Finally, commas can introduce parenthetical remarks that comment on the main clause. Here's the thing — these remarks may consist of a phrase preceded by “which” or “that” and typically end with a comma unless they appear at the very start of a sentence. Proper placement ensures readability and prevents ambiguity.
13. Passive Voice and Its Implications
Passive constructions shift focus from the actor to the object being acted upon. Both structures convey the same event, yet they carry different nuances: the passive version can obscure responsibility, making it useful in formal reports where the doer is irrelevant. Here's the thing — while active voice (“The chef prepared the dish”) highlights who performs the action, the passive form (“The dish was prepared by the chef”) places the dish as the subject. On the flip side, overuse of passive voice can render writing vague or evasive, so a balanced mix is advisable That's the whole idea..
In academic writing, passive voice is common in methods sections, where the aim is to describe procedures rather than credit specific researchers. Day to day, conversely, in narrative prose, active voice tends to engage readers more directly. Understanding when to employ each mode helps maintain clarity and style consistency throughout a piece.
Counterintuitive, but true Simple, but easy to overlook..
Conclusion
Subject‑verb agreement, the influence of intervening phrases, and the correct choice of verbs with “there is/are,” numbers, fractions, and relative pronouns form the core pillars of grammatical precision. By applying these principles deliberately, writers can produce work that is not only grammatically sound but also compelling and easy to understand. Mastering commas and their coordination rules further refines sentence construction, while a nuanced grasp of passive voice enhances both clarity and stylistic variety. This systematic approach empowers anyone aiming for polished, error‑free communication across genres and platforms.
