Why Subject-Verb Agreement Matters in English
Subject-verb agreement forms the backbone of clear and correct English sentences. When the subject and verb match in number, your writing flows naturally and professionally. Whether you’re drafting an email, crafting a blog post, or preparing a school essay, mastering this rule helps avoid embarrassing mistakes that can distract readers.
At its core, the principle is straightforward: singular subjects take singular verbs, and plural subjects take plural verbs. Yet many writers stumble over tricky cases involving collective nouns, compound subjects, or indefinite pronouns. This guide breaks everything down into simple steps with plenty of real-world examples.
The Basic Rules of Subject-Verb Agreement
Start with the fundamentals. A singular subject requires a singular verb. For instance, “The cat sleeps on the windowsill.” Here, “cat” is singular, so the verb “sleeps” ends with an “s.”
Conversely, plural subjects pair with plural verbs: “The cats sleep on the windowsill.” No “s” on the verb. This pattern holds for most regular verbs in the present tense.
Examples of Singular and Plural Agreement
- The teacher explains the lesson clearly every morning.
- The teachers explain the lessons clearly every morning.
- My friend enjoys hiking in the mountains during summer.
- My friends enjoy hiking in the mountains during summer.
Notice how the verb changes based solely on whether the subject is one or more than one. Consistency is key for polished writing.
Tricky Situations: Collective Nouns and Compound Subjects
Collective nouns like “team,” “family,” “committee,” or “audience” can confuse writers. In American English, these usually take singular verbs when the group acts as a single unit: “The team wins the championship.” However, if members act individually, plural verbs work: “The team are arguing among themselves.” British English often treats collectives as plural more freely.
Compound subjects joined by “and” typically take plural verbs: “The dog and the cat play together in the yard.” But when subjects are joined by “or” or “nor,” the verb agrees with the nearest subject: “Neither the manager nor the employees like the new policy.” In this case, “employees” is closer, so the plural “like” is correct.
Indefinite Pronouns: Singular or Plural?
Words like “everyone,” “somebody,” “nobody,” and “each” are singular and require singular verbs. “Everyone is welcome to join the event.” Even though “everyone” refers to many people, grammatically it’s singular.
Others like “both,” “few,” and “many” are plural: “Both options seem reasonable.” Then there are pronouns that depend on context: “Some of the cake is gone” (singular, referring to part of one cake) versus “Some of the cakes are gone” (plural).
Practice Sentences for Indefinite Pronouns
“All of the information provided by the expert helps us understand the topic better.”
The singular “helps” agrees with the singular idea of “information.”
Special Cases Involving Quantities and Measurements
Amounts, distances, and periods of time often take singular verbs when considered as a single unit: “Five miles is a long distance to walk.” “Ten dollars seems too much for that item.”
However, if the items are viewed individually, the verb becomes plural: “Five miles of trails are available for hiking.” Context determines the choice.
Common Mistakes and How to Fix Them
One frequent error occurs with phrases that separate the subject from the verb. For example, “The box of chocolates, along with the flowers, make a nice gift.” The actual subject is “box,” which is singular, so it should be “makes.” Ignore interrupting phrases when checking agreement.
Another pitfall involves inverted sentences: “There is many reasons to celebrate.” Correct version: “There are many reasons to celebrate.” The verb agrees with the true subject that follows.
Writers sometimes mismatch with relative clauses. “The students who study hard succeed.” Both subject and verb stay plural here. Always locate the main subject carefully.
More Examples of Mistakes to Avoid
- Incorrect: The list of items are on the table. Correct: The list of items is on the table.
- Incorrect: Each of the players have a unique skill. Correct: Each of the players has a unique skill.
- Incorrect: My sister, as well as my brothers, are coming to visit. Correct: My sister, as well as my brothers, is coming to visit.
Tips for Mastering Subject-Verb Agreement
Reading your work aloud helps catch mismatches because errors often sound wrong. Another strategy is to temporarily remove modifying phrases to isolate the core subject and verb.
Practice by rewriting paragraphs from books or articles, focusing only on agreement. Over time, this rule becomes instinctive. Tools like grammar checkers can flag issues, but understanding the logic builds stronger skills than relying on software alone.
In professional settings, strong grammar boosts credibility. Clients and colleagues notice when communications are error-free. For students, mastering agreement improves grades on written assignments.
Advanced Scenarios: Titles, Gerunds, and More
Book titles and organization names are singular even if they sound plural: “The United Nations is holding a summit.” “Pride and Prejudice remains a classic novel.”
Gerund phrases as subjects take singular verbs: “Swimming in the ocean requires strong skills.” The action is treated as one concept.
When dealing with fractions or percentages, the verb agrees with the noun that follows “of”: “Three-quarters of the pie was eaten.” “Three-quarters of the apples were eaten.”
Putting It All Together: A Quick Review Exercise
Consider these sentences and identify the correct verb:
- The group of musicians (plays/play) beautifully together.
- Either the books or the magazine (belongs/belong) on that shelf.
- Mathematics (is/are) my favorite subject.
Answers: plays, belong, is. Regular self-testing reinforces the patterns.
Remember that dialects and style guides sometimes differ slightly. American English tends toward singular for collectives, while British English leans plural. Choose consistency within your document or audience expectations.
