Why Subject-Verb Agreement Matters
Subject-verb agreement might seem like a basic grammar rule, but it trips up even experienced writers. When the subject and verb don’t match in number, your sentence sounds off. The good news? Once you understand a few common trouble spots, you can fix these errors quickly. This guide breaks down the trickiest cases into simple, memorable rules. Mastering subject-verb agreement not only improves clarity but also boosts your credibility as a writer. Whether you’re crafting an email, a report, or a novel, consistent agreement makes your writing polished and professional.
The Core Rule: Singular vs. Plural
Before diving into exceptions, remember the basics: a singular subject takes a singular verb, and a plural subject takes a plural verb. For most nouns, add an -s to the verb in the third-person singular (he, she, it). But watch out for irregular verbs like to be (is/are, was/were) and to have (has/have).
- Singular: The cat chases the mouse.
- Plural: The cats chase the mouse.
Seems easy, right? But reality gets messy when subjects are unclear. Consider sentences with multiple nouns or phrases that obscure the true subject. The key is to identify the head noun that the verb must agree with.
1. Collective Nouns
Collective nouns (team, family, committee, audience) refer to a group. The tricky part: in American English, treat them as singular if the group acts as one unit, and plural if the members act individually.
- Singular: The team is winning its game. (all acting together)
- Plural: The team are arguing among themselves. (individual members)
When in doubt, make the collective noun singular and rephrase if it sounds weird. British English often treats collective nouns as plural, but consistency is key. For example, in British English you might hear “The government are divided,” while American English prefers “The government is divided.” Choose the style that fits your audience and stick with it.
2. Indefinite Pronouns
Indefinite pronouns like everyone, someone, anybody, nobody, each, either, neither are almost always singular—even when they seem plural.
- Correct: Everyone has finished their homework. (not have)
- Correct: Neither of the options is ideal. (not are)
But watch out for pronouns like all, some, any, none—they can be singular or plural depending on the noun they refer to.
- All of the cake is gone. (cake is singular)
- All of the cookies are gone. (cookies are plural)
Use none as singular in formal writing, though plural is acceptable in casual contexts. For instance, “None of the students are ready” is widely accepted, but purists prefer “None of the students is ready.” Follow your style guide or audience expectation.
3. Compound Subjects
When two subjects are joined by and, the verb is usually plural. But there are exceptions.
- Plural: The cat and the dog are friends.
- Singular: Peanut butter and jelly is my favorite. (considered a single unit)
When subjects are joined by or or nor, the verb agrees with the subject closest to it.
- Singular: Either the manager or the assistant is responsible. (assistant is singular)
- Plural: Neither the assistant nor the managers are available. (managers is plural)
Tip: To avoid awkward sounding sentences, rephrase by placing the plural subject closer to the verb. For example, instead of “Neither the managers nor the assistant is available,” you could write “Neither the assistant nor the managers are available.”
4. Interrupting Phrases
Words that come between the subject and verb don’t affect agreement. Ignore prepositional phrases like along with, together with, as well as, including.
- Correct: The teacher, along with her students, is excited. (subject is teacher, singular)
- Wrong: The teacher, along with her students, are excited.
Similarly, phrases starting with of often confuse: The box of chocolates is on the table (box is the subject, not chocolates). A good trick: mentally remove the interrupting phrase to isolate the subject. For instance, “The bouquet of roses is beautiful” becomes clear when you focus on “bouquet.”
5. Inverted Order (There / Here)
Sentences beginning with there or here invert the usual subject-verb order. The true subject comes after the verb.
- Singular: There is one apple on the table.
- Plural: There are three apples on the table.
In speech, people often use there’s with a plural noun, but in writing, use there are for consistency. The same rule applies to here: “Here are the keys you requested.” Avoiding the contraction there’s in plural contexts is a sign of careful writing.
6. Singular Nouns That Look Plural
Some words end in -s but are singular: news, mathematics, economics, politics, athletics. Treat them as singular.
- Correct: The news is surprising.
- Correct: Economics was her major.
Conversely, words like pants, scissors, tweezers, glasses (eyewear) are plural and take a plural verb: The scissors are sharp. If you need singular, use a pair of: “A pair of scissors is on the table.” Be careful with words like series and species, which can be singular or plural: “A series of lectures is scheduled” (series treated as singular) vs. “Two series are running concurrently.”
7. Titles and Company Names
Titles of books, movies, and organizations are singular even if they contain plural words.
- Correct: “The Chronicles of Narnia” is a classic.
- Correct: The United Nations has many members.
Treat company names as singular: Microsoft announces its new product. Even if the company name ends in “s” like “Starbucks,” it takes a singular verb: “Starbucks is opening a new store.” The same applies to band names: “The Beatles is my favorite band” (though many treat plural band names as plural informally, consistency with the singular convention is safer).
8. Quantifiers and Amounts
When dealing with expressions of time, money, distance, or weight, treat the amount as a single unit if it refers to a lump sum. For example, “Ten dollars is too high a price” (the amount as a whole) vs. “Ten dollar bills are on the table” (individual items). Similarly, “Three miles is a long walk” but “The last three miles are uphill.” Also consider phrases like “a number of” vs. “the number of”: “The number of participants is large” (singular), but “A number of participants are waiting” (plural).
9. Subjects with ‘and’ That Form a Single Unit
Some compound subjects with and are treated as singular because they represent one idea: “Bread and butter is my breakfast” (one dish), “Law and order matters to society” (one concept). This contrasts with separate items: “Bread and butter are on the table.” Context is key—if the two elements are commonly paired or considered inseparable, the singular verb fits.
Practice Makes Perfect
The best way to master subject-verb agreement is to read your sentences aloud. Pause at the verb and check the subject—ignore any interrupting words. Keep a list of tricky cases handy. With these rules, you’ll avoid common grammar pitfalls and write more clearly. Additionally, proofread your work with a focus on agreement. Over time, these patterns will become second nature.
Remember: The subject of a sentence is never inside a prepositional phrase. Cross out those phrases to see the true subject.
Start paying attention to these patterns in your everyday writing. Before long, correct agreement will feel natural. If you ever feel uncertain, consult a grammar guide or use online tools to double-check. Consistent practice is the key to confidence, and soon you’ll be able to spot and fix agreement errors without a second thought.
