Subject–verb agreement is one of the first grammar patterns ESL learners notice and one of the last they fully master. The rule sounds simple: a singular subject takes a singular verb, and a plural subject takes a plural verb. In real English, though, agreement becomes tricky when sentences include prepositional phrases, indefinite pronouns, compound subjects, collective nouns, or inverted word order. I teach this topic often because small agreement errors can make otherwise strong writing sound unpolished, especially in academic essays, business emails, and test responses.
In grammar, the subject is the person, thing, or idea performing the action or being described. The verb is the action or linking word connected to that subject. Agreement means the verb form matches the subject in number. For example, “The student writes” is correct because “student” is singular, while “The students write” is correct because “students” is plural. In the present simple, agreement matters most with third-person singular forms such as “he runs,” “she studies,” and “it works.” Past tense verbs usually create fewer problems because many forms do not change.
Why does this matter? Clear subject–verb agreement improves accuracy, comprehension, and confidence. Examiners in IELTS, TOEFL, and Cambridge English tests notice these errors quickly. So do hiring managers reading cover letters and teachers marking essays. I have seen learners with advanced vocabulary lose points because they wrote “The results shows” or “Everyone have.” This hub article gives you the core rules, the exceptions that appear most often, and practical examples you can apply immediately across the wider Grammar section.
The Core Rule: Match the Verb to the Real Subject
The basic rule is straightforward: singular subjects take singular verbs, and plural subjects take plural verbs. In the present simple, singular third-person subjects usually add -s or -es to the main verb: “My brother works late.” Plural subjects use the base form: “My brothers work late.” With the verb be, the pattern changes by person and number: “I am,” “you are,” “he is,” “they are.” Mastering these forms is essential because they appear in almost every sentence type.
The most common learner mistake is focusing on the noun closest to the verb instead of the actual subject. In the sentence “The list of items is on the desk,” the subject is “list,” not “items,” so the singular verb “is” is correct. The same logic applies to “The quality of the reports has improved.” The noun in the prepositional phrase does not control the verb. When editing, I tell students to remove extra words mentally and test the sentence: “The list is,” “The quality has.”
Another useful check is to ask, “Who or what is doing the action?” In “The teachers in the new training program work hard,” the subject is “teachers,” so “work” is correct. In “The new training program for teachers works well,” the subject becomes “program,” so “works” is correct. This habit prevents many errors before they appear on the page.
Tricky Subjects ESL Learners Meet Most Often
Several subject types cause repeated confusion. Indefinite pronouns such as “everyone,” “someone,” “anybody,” and “each” are singular in standard English, so they take singular verbs: “Everyone wants feedback.” “Each of the answers is possible.” By contrast, “many,” “few,” “several,” and “both” are plural: “Many were absent.” “Both agree.” Some pronouns depend on the noun that follows. “Some of the cake is gone” is singular because “cake” is uncountable, but “some of the cookies are gone” is plural because “cookies” is countable and plural.
Collective nouns can also be difficult. In American English, words like “team,” “staff,” “government,” and “family” are usually treated as singular when the group acts as one unit: “The team is winning.” In British English, plural agreement is often acceptable when the members are acting individually: “The team are wearing different shirts.” For ESL learners, consistency matters more than imitation. If you are writing for an American school or employer, singular agreement is usually the safer choice.
Titles of books, films, subjects, and organizations are generally singular even when they look plural: “Economics is difficult at first.” “The United Nations has issued a statement.” Amounts of time, money, distance, or measurement often take singular verbs when viewed as one unit: “Ten dollars is enough.” “Five kilometers is a long walk in this heat.”
| Subject type | Correct example | Why |
|---|---|---|
| Indefinite pronoun | Everyone knows the rule. | “Everyone” is singular. |
| Collective noun | The class is ready. | The group acts as one unit. |
| Title | Mathematics requires practice. | The subject name is singular. |
| Measurement | Twenty minutes is enough. | The amount is one unit. |
Compound Subjects, Either/Neither, and Inverted Sentences
When two subjects are joined by “and,” they usually take a plural verb: “Sara and Lina study together.” However, if the two words refer to one idea or one combined item, a singular verb may be correct: “Peanut butter and jelly is my usual lunch.” This is not just a grammar trick; meaning decides agreement. If the writer sees two separate people or things, use a plural verb. If the phrase functions as one concept, use a singular verb.
With “either…or,” “neither…nor,” and “not only…but also,” the verb usually agrees with the subject closest to it. For example, “Either the teacher or the students are presenting today” is correct because “students” is nearer the verb. “Either the students or the teacher is presenting today” is also correct for the same reason. This proximity rule is common in edited English, though many style guides also recommend rewriting awkward sentences to avoid confusion.
Inverted sentences can hide the subject. In “There is a problem,” the real subject is “problem,” so the singular verb “is” is correct. In “There are several problems,” the real subject is “problems,” so “are” is required. The same issue appears after adverbs and question forms: “Where are the keys?” “On the wall hangs a portrait.” Because spoken English often reduces forms quickly, learners may hear incorrect patterns in conversation and repeat them in writing. Written grammar should still match the actual subject.
Here is a practical method I use in class: first find the verb, then ask who or what controls it, then ignore interrupting phrases, and finally check whether the sentence has a joining structure like “and” or “either…or.” This four-step approach works well on grammar quizzes and during self-editing.
Special Cases, Common Errors, and How to Self-Correct
Some nouns look plural but are singular, including “news,” “physics,” “measles,” and “linguistics.” We say “The news is surprising,” not “The news are surprising.” Other nouns are plural in form and usually take plural verbs, such as “scissors,” “pants,” “police,” and “cattle.” You would write “The police are investigating.” If you need a singular expression, use a pair phrase: “This pair of scissors is sharp.” These patterns are best learned as fixed forms rather than guessed.
Fractions and percentages depend on the noun after of. “Fifty percent of the cake is gone” is singular; “Fifty percent of the students are absent” is plural. Data-related nouns can vary by style. In everyday modern English, “data” is often treated as a mass noun taking a singular verb in business and technology writing, but in scientific contexts many editors still prefer the plural: “The data are limited.” Know your audience and stay consistent.
One of the fastest ways to improve is targeted proofreading. After writing, check every present simple verb and every form of be, have, and do. These verbs reveal agreement problems clearly. Grammar tools like Grammarly, Microsoft Editor, and the Hemingway Editor can catch some errors, but they are not perfect with collective nouns, inverted sentences, or style-based choices. A reliable self-check is to underline the subject once and the verb twice. If they do not match, revise the sentence.

Subject–verb agreement depends on all of them, which is why this Miscellaneous hub matters.
Subject–verb agreement becomes much easier when you stop guessing and start identifying the true subject. The main rules are stable: singular subjects take singular verbs, plural subjects take plural verbs, and extra words between the subject and verb do not change that relationship. The most important trouble spots are indefinite pronouns, collective nouns, compound subjects, either/neither structures, measurements, percentages, and inverted sentences. Once you recognize these patterns, you can correct many errors in seconds.
For ESL learners, the real benefit is not only grammatical accuracy but also stronger credibility. Correct agreement makes essays clearer, emails more professional, and exam writing more controlled. I have seen learners improve quickly by doing two things consistently: reading model sentences carefully and proofreading specifically for subject–verb pairs instead of trying to fix everything at once. Short daily practice works better than memorizing long exception lists without context.
Use this page as your hub for the wider Miscellaneous area of Grammar, then build outward into connected lessons on pronouns, nouns, tenses, clauses, and sentence patterns. Start with ten sentences from your own writing today, check each subject and verb, and rewrite any pair that does not agree. That small habit will sharpen your English faster than most learners expect.
Frequently Asked Questions
What is subject–verb agreement, and why is it so important for ESL learners?
Subject–verb agreement means that the verb form must match the subject in number. A singular subject takes a singular verb, and a plural subject takes a plural verb. For example, The student writes is correct because student is singular, while The students write is correct because students is plural. This sounds like a basic rule, but it affects nearly every sentence you say or write in English.
For ESL learners, subject–verb agreement matters because it strongly affects clarity, accuracy, and how natural your English sounds. Even when vocabulary and sentence structure are strong, agreement errors can make writing feel incomplete or unpolished. Compare My brother live in Canada with My brother lives in Canada. The meaning is clear in both cases, but the second sentence sounds correct and fluent. That is why this topic is introduced early in language learning and practiced for a long time.
It is also important because English agreement is not always as simple as “one subject, one verb.” Problems appear when a sentence includes extra words between the subject and verb, when the subject is an indefinite pronoun like everyone or each, when two nouns are joined together, or when the subject comes after the verb. Learning the basic rule is the first step, but mastering the exceptions and confusing patterns is what helps learners write with confidence.
How can I identify the real subject when extra words come between the subject and the verb?
This is one of the most common causes of agreement mistakes. In many English sentences, the subject and verb are separated by prepositional phrases or other descriptive words. The key is to find the core subject and ignore the interrupting phrase when choosing the verb. For example, in the sentence The list of items is on the table, the subject is list, not items. Since list is singular, the correct verb is is, not are.
Prepositional phrases often begin with words like of, in, with, for, or between. These phrases may contain plural nouns that distract you. For example, The teacher with the two assistants is preparing the lesson is correct because the subject is teacher. Similarly, The color of the walls was changed is correct because the subject is color, not walls.
A useful strategy is to mentally remove the extra phrase and test the sentence. If you shorten The book on the shelves belongs to Maria, you get The book belongs to Maria. Now the agreement is easier to hear. This habit is especially helpful in longer academic or formal sentences, where the true subject can be hidden by details. When you train yourself to identify the noun that controls the verb, agreement becomes much more accurate.
Which indefinite pronouns are singular, and why do they often cause agreement errors?
Indefinite pronouns are words such as everyone, someone, anyone, nobody, each, and everybody. Many of these are grammatically singular, even though they may refer to more than one person in a general sense. That is why we say Everyone is ready, Each of the students has a book, and Nobody knows the answer. ESL learners often make mistakes here because these words seem plural in meaning, but English treats them as singular for verb agreement.
One especially confusing structure is each of or one of. In Each of the players is wearing a badge, the subject is each, which is singular. In One of my friends lives in Tokyo, the subject is one, not friends. The plural noun after of can pull learners toward the wrong verb form, so it is important to focus on the pronoun at the beginning of the phrase.
Some indefinite pronouns can be singular, plural, or both depending on the noun that follows. Words like some, all, most, and none change according to the meaning. For example, Some of the cake is gone uses a singular verb because cake is an uncountable noun, but Some of the cookies are gone uses a plural verb because cookies is plural. When you learn indefinite pronouns in groups and study example sentences, agreement patterns become easier to remember.
How do compound subjects work, and when do they take a singular or plural verb?
Compound subjects are subjects made of two or more parts, usually connected by and, or, or nor. In most cases, two subjects joined by and take a plural verb because they form a plural idea. For example, Tom and Jerry are famous cartoon characters and The manager and the assistant work well together both use plural verbs. This is the standard rule ESL learners learn first.
However, there are important exceptions. If two nouns joined by and refer to one person, one thing, or one unit, the verb can be singular. For example, Peanut butter and jelly is my favorite sandwich treats the phrase as one food combination. Likewise, The owner and manager is speaking can be correct if one person is both the owner and the manager. Meaning matters here, not just the presence of and.
When subjects are joined by or or nor, the verb usually agrees with the subject closest to it. For example, Either the teacher or the students are presenting today is correct because students is nearest the verb, while Either the students or the teacher is presenting today is also correct because teacher is nearest the verb. This “nearest subject” rule is very useful, but it can still sound awkward if singular and plural subjects are mixed. In formal writing, many teachers recommend rewriting the sentence to make the structure clearer.
Why are collective nouns and inverted sentences so confusing in subject–verb agreement?
Collective nouns are nouns that refer to a group as a single unit, such as team, family, class, government, and committee. In American English, these nouns are usually treated as singular when the group acts as one unit: The team is winning and My family lives nearby. However, in some contexts, especially in British English, a collective noun may take a plural verb when the members are seen as acting individually: The team are wearing different uniforms. This difference confuses many learners because both grammar and style can affect the choice.
Inverted sentences are also difficult because the subject comes after the verb instead of before it. This happens in sentences beginning with there or in questions and certain formal structures. For example, in There is a book on the desk, the real subject is book. In There are three books on the desk, the real subject is three books. Learners sometimes match the verb to there, but there is not the subject. The verb must agree with the noun that follows.
To handle both collective nouns and inverted word order, the best approach is to slow down and ask two questions: “Who or what is the true subject?” and “Is it being treated as one unit or more than one?” This method helps in sentences like Here are the results, There is a problem, and The committee has made its decision. Once you stop relying only on word position and begin identifying the real subject and its meaning, these advanced agreement patterns become much easier to control.
