Why Subject-Verb Agreement Matters in Everyday Writing
Imagine reading a sentence that feels slightly off, like a picture hanging crooked on the wall. The words make sense, but something disrupts the flow. Often, that subtle issue stems from subject-verb agreement errors. This fundamental grammar rule ensures your subjects and verbs match in number—singular with singular, plural with plural. When they align, your writing sounds polished and professional. When they don’t, readers may stumble or question your credibility.
In emails to colleagues, blog posts for your audience, or reports for school, strong subject-verb agreement keeps your message clear. It prevents confusion and builds trust. Many native speakers and learners alike trip over this rule in complex sentences, especially with collective nouns, interrupting phrases, or compound subjects. Fortunately, the principles are straightforward once broken down step by step.
This guide simplifies subject-verb agreement for anyone seeking clearer English. We’ll cover core rules, examine real examples, tackle tricky cases, and share practical exercises. By the end, you’ll spot and fix these errors confidently, making your writing smoother and more impactful.
The Basic Rule: Singular Subjects Take Singular Verbs
At its heart, subject-verb agreement follows one simple principle. A singular subject pairs with a singular verb form, usually ending in -s or -es in the present tense. A plural subject takes the base verb form without that ending.
Consider these straightforward examples:
- The dog barks loudly at strangers. (Singular subject “dog” + singular verb “barks”)
- The dogs bark loudly at strangers. (Plural subject “dogs” + plural verb “bark”)
The same logic applies to other verbs. “She runs every morning” works because “she” is singular. Change it to “They run every morning,” and the verb shifts to match the plural subject.
This pattern holds for most regular verbs. Irregular verbs like “to be” follow unique forms: “is” for singular (he is, she is, it is) and “are” for plural (they are, we are). Mastering these basics builds a strong foundation before tackling exceptions.
Identifying the Subject: Don’t Get Distracted by Extra Words
One common pitfall involves phrases that sit between the subject and verb. These interrupters can trick your ear into choosing the wrong verb form. Always identify the true subject first, ignoring prepositional phrases or descriptive clauses.
Look at this incorrect sentence: “The box of old books were heavy.” The subject is “box,” which is singular, so the verb should be “was,” not “were.” The correct version reads: “The box of old books was heavy.”
Another example: “A team of talented players are winning the championship.” Here, “team” acts as a singular collective noun, requiring “is” instead of “are.” Revised: “A team of talented players is winning the championship.”
Tip: Cross out words between the subject and verb mentally. This technique reveals the core pairing instantly. Practice with sentences from your own writing to sharpen this skill.
Compound Subjects: When Two Become One (or Stay Separate)
Compound subjects joined by “and” usually take a plural verb because they create a plural idea. “The chef and the waiter prepare the meals efficiently.” Both people work together, so plural “prepare” fits.
Exceptions arise when the compound refers to a single unit or idea. “Peanut butter and jelly is my favorite sandwich.” Even though two items appear, they form one dish, demanding a singular verb.
When “or” or “nor” connects subjects, the verb agrees with the closest noun. “Neither the manager nor the employees were satisfied.” “Employees” is plural and nearest, so plural “were” wins. Flip it: “Neither the employees nor the manager was satisfied.” Now singular “manager” controls the verb.
These nuances add depth to your sentences without complicating them unnecessarily. Pay attention to proximity, and your choices will feel natural.
Collective Nouns and Indefinite Pronouns: Special Cases
Collective nouns like “family,” “committee,” “audience,” or “staff” can confuse writers. Treat them as singular when the group acts as one unit: “The committee decides on the budget today.” If members act individually, switch to plural: “The committee argue among themselves about details.” American English often prefers singular for collectives, while British English allows more flexibility.
Indefinite pronouns also require care. Words like “everyone,” “somebody,” “nobody,” and “each” are singular despite sounding broad. “Everyone enjoys a good story.” “Each of the students submits an assignment.”
Contrast with “few,” “many,” “several,” or “both,” which take plural verbs: “Few understand the complexity at first.” Quantifiers like “all” or “some” depend on context: “All of the cake is gone” (singular mass noun) versus “All of the cakes are gone” (plural count nouns).
Context guides these decisions. Reading your sentence aloud often highlights mismatches that eyes might miss.
Tricky Situations: There Is/There Are and Questions
Sentences starting with “there” or “here” invert normal order, hiding the subject afterward. “There is a reason for the delay.” The subject “reason” is singular. “There are several reasons for the delay.” Now plural “reasons” calls for “are.”
In questions, locate the subject carefully. “Where is the report I requested?” Singular “report.” “Where are the reports I requested?” Plural adjustment.
Relative clauses introduce another layer. The verb agrees with the antecedent of the relative pronoun. “The book that contains the answers belongs to me.” “Contains” matches singular “book.” But “The books that contain the answers belong to me.” Plural shift.

Common Mistakes and How to Fix Them Quickly
Even experienced writers slip up occasionally. Here are frequent errors with corrections:
- Incorrect: “The list of requirements were updated yesterday.” Correct: “The list of requirements was updated yesterday.” (Subject: “list”)
- Incorrect: “My brother, along with his friends, enjoy hiking.” Correct: “My brother, along with his friends, enjoys hiking.” (Subject: “brother”)
- Incorrect: “Neither of the options are ideal.” Correct: “Neither of the options is ideal.” (“Neither” is singular)
Proofreading strategy: Read backward from the end, sentence by sentence. This disrupts familiar flow and spotlights agreement issues. Or use text-to-speech tools to hear your words aloud—ears catch what eyes overlook.
Another tip: Maintain consistency in tense while checking agreement. Mixing present and past unnecessarily compounds problems. Stick to one timeframe unless the meaning demands a shift.
Practice Exercises to Build Confidence
Apply what you’ve learned with these targeted exercises. Choose the correct verb in each sentence.
- The group of protesters (was/were) peaceful throughout the event.
- Either the supervisor or the team members (decides/decide) the schedule.
- Everybody in the class (has/have) completed the project on time.
- The stack of papers on the desk (needs/need) sorting immediately.
- There (is/are) a coffee mug and three notebooks left in the conference room.
Answers: 1. was (group as unit); 2. decide (closer plural subject); 3. has (everybody singular); 4. needs (stack singular); 5. are (plural items follow).

Advanced Tips for Professional and Academic Writing
In formal contexts, precision elevates your work. Avoid starting too many sentences with “there is” constructions, as they can weaken impact. Instead, lead with the true subject: “Several solutions exist” rather than “There are several solutions.”
Watch for subject-verb agreement across longer distances in complex sentences. Subordinate clauses shouldn’t distract from the main pairing. For instance: “The scientist who conducted the experiments along with her dedicated assistants publishes findings regularly.” The singular “scientist” governs “publishes.”
Style guides like Chicago or APA emphasize consistency. Review your organization’s preferred approach to collectives or pronouns. Small choices accumulate, shaping your voice as clear, authoritative, or approachable.
Digital tools help during drafting, but they aren’t perfect. Grammar checkers flag obvious mismatches yet miss nuanced context like collective nouns acting individually. Combine software with human judgment for best results.
Final Thoughts: Agreement as the Foundation of Clear Communication
Subject-verb agreement might seem basic, yet it underpins effective English. When subjects and verbs harmonize, ideas shine without distraction. Readers focus on your message rather than decoding awkward phrasing.
Return to this guide whenever doubts arise. Review examples, test tricky sentences, and celebrate progress as errors decrease. Over time, these habits refine not just grammar but overall writing confidence.
