Introduction
There is a sentence hiding in almost every competitive exam paper that looks perfectly fine until you read it twice.
“The quality of these apples are poor.”
Something feels off, doesn’t it? The subject is quality — singular. The verb should be is. But the word apples sitting right next to the verb pulls most readers toward are. And that is exactly the kind of trap examiners love.
Subject-verb agreement is one of the highest-scoring grammar topics across SSC CGL, SBI PO, IBPS Clerk, UPSC CSAT, IELTS, CAT, and CUET. It rewards precision, not just instinct. Knowing the basic rule — singular subjects take singular verbs, plural subjects take plural verbs — gets you through beginner-level questions. But the exam questions rarely operate at that level.
This guide covers 20 advanced rules of subject-verb agreement, complete with real sentence patterns, exam-style traps, memory anchors, and the kind of analysis that turns weak spots into sure marks. Every rule here is followed by a clear example and a quick “exam tip” that most other resources miss.
What is it?
Subject-verb agreement is the grammatical principle that the verb in a sentence must match its subject in number and person. A singular subject takes a singular verb; a plural subject takes a plural verb. The challenge in exams is identifying the true grammatical subject — not the nearest noun — and applying the correct rule.
Key Takeaways
Find the true subject first — never the nearest noun.
Parenthetical phrases (along with, as well as) do not change the subject.
Either/or and neither/nor follow the proximity rule — verb agrees with the nearer subject.
Each, every, many a, one of — all singular verbs, always.
“The number of” = singular. “A number of” = plural.
Gerunds and infinitives as subjects always take singular verbs.
Fractions and percentages agree with the noun after of.
The poor, the elderly, the rich — always plural.
Titles of works — always singular.
There and here are never the subject — find the noun after the verb.
What Is Subject-Verb Agreement and Why Does It Matter in Exams?
Subject-verb agreement, also called grammatical concord, is the matching of a verb’s form to the number and person of its subject. Every finite verb in an English sentence must agree with its subject.
The reason this matters so much in competitive exams is that question setters design sentences specifically to confuse you. They place distracting phrases between the subject and verb, use collective nouns that feel plural but are not, or build correlative pairs like either/or and neither/nor that follow a specific hierarchy.
A student who understands only the surface rule — singular verb for singular subject — will fall for roughly half the exam traps. A student who knows all 20 rules will not.
The “Elephant in the Middle” Problem
Before getting into the rules, understand this fundamental concept.
Exam sentences often insert a large phrase between the subject and the verb. This phrase acts like an elephant standing in the middle of a road — it blocks your view of what came before it.
“The list of items required for the expedition are checked.”
The word items sits right before the verb, so your brain defaults to the plural are. But the subject is list — singular. The correct verb is is.
The fix is simple: mentally cross out everything between the subject and verb. Find the grammatical subject first. Then choose the verb.
This single habit prevents a significant portion of subject-verb agreement errors, especially in long, complex sentences that competitive exams favour.
20 Advanced Rules of Subject-Verb Agreement
Rule 1: Parenthetical Phrases Do Not Change the Subject
Words and phrases like along with, together with, as well as, accompanied by, in addition to, including, besides, rather than, and no less than are not conjunctions. They are prepositions or subordinators. They do not create a compound subject.
“The principal, along with all the teachers, was present at the ceremony.”
The subject remains principal — singular. The phrase along with all the teachers is a parenthetical addition, grammatically invisible to the verb.
Exam Tip: These phrases appear in at least one question in almost every SSC and banking paper. If you see them, treat them as invisible and focus on the first subject alone.
Rule 2: Either/Or and Neither/Nor — The Proximity Rule
When two subjects are connected by either…or or neither…nor, the verb agrees with the subject that is nearer to it.
“Neither the manager nor the employees were informed.” “Neither the employees nor the manager was informed.”
Same sentence, different word order — different verb.
Exam Tip: This is called the proximity rule or the rule of the nearer subject. When both subjects are singular, the verb is singular. When both are plural, the verb is plural. When they are mixed, the nearer one wins.
Rule 3: “Each” and “Every” Always Take a Singular Verb
Each and every are distributive determiners. They look at members of a group one by one, individually. That individual focus makes them grammatically singular — always.
“Each of the students has submitted the assignment.” “Every man, woman, and child is affected by this decision.”
Even when each or every refers to what sounds like multiple people, the verb remains singular.
Exam Tip: “Each and every” together also takes a singular verb. “Each and every student was given a certificate.”
Rule 4: “One of” Takes a Plural Noun but a Singular Verb
This is a classic two-part trap. After one of, the noun must be plural. But the verb that follows must be singular — because the subject is one, not the plural noun.
“One of the windows is broken.” — NOT “One of the window is” and NOT “One of the windows are”
Exam Tip: “One of the + plural noun + singular verb” is the fixed structure. Any deviation is an error.
Rule 5: “The Number of” vs. “A Number of”
These two look almost identical but behave oppositely.
| Expression | Verb | Logic |
|---|---|---|
| The number of + noun | Singular | “The number” is a definite, countable figure |
| A number of + noun | Plural | “A number of” means “several/many” — indefinite |
“The number of applicants is rising every year.” “A number of applicants have withdrawn their forms.”
Exam Tip: Think of it this way — the number refers to one specific count (one thing = singular). A number means many (many things = plural). This distinction appears in bank exams and IELTS writing feedback almost identically.
Rule 6: Collective Nouns — Unit vs. Members
A collective noun (team, committee, jury, class, audience, staff, government, crowd) can take either a singular or a plural verb depending on whether it acts as a unit or as individual members.
“The jury has delivered its verdict.” — Acting as one unit “The jury were divided in their opinions.” — Acting as individuals
In Indian competitive exams (SSC, UPSC), collective nouns almost always take singular verbs unless the sentence specifically highlights division or disagreement among members.
In British English, collective nouns more freely take plural verbs. This is worth knowing for IELTS test takers.
Rule 7: Indefinite Pronouns — The Two Groups
Indefinite pronouns fall into two groups, and you must memorise which group each belongs to.
Always singular: someone, somebody, something, anyone, anybody, anything, everyone, everybody, everything, no one, nobody, nothing, each, either, neither, one, another
Always plural: both, few, many, several, others
“Everyone in the hall was seated.” “Many of the delegates were absent.”
Exam Tip: The “body” words (somebody, everybody, nobody, anybody) and “thing” words (something, everything, nothing, anything) are all singular — every single one.
Rule 8: Subjects Joined by “And” — Usually Plural
When two or more subjects are joined by and, the verb is generally plural. This is the baseline rule.
“Tom and Jerry are cartoon characters.”
But there are three important exceptions:
Exception A: When the two nouns refer to the same person or thing:
“The author and publisher of this book is my uncle.” (one person wearing two hats)
Exception B: When each noun is preceded by each or every:
“Every teacher and every student was asked to sign.”
Exception C: When two things are considered a fixed pair or concept:
“Bread and butter is my breakfast.” “Rice and curry is what she ordered.”
Rule 9: Fractions and Percentages
When a fraction or percentage is the subject, the verb agrees with the noun that follows of.
“One-third of the students are absent.” (students = plural) “One-third of the water has evaporated.” (water = uncountable/singular) “Thirty percent of the work is done.” (work = singular)
Exam Tip: Remove the fraction/percentage from your mind and focus only on the noun after of. That noun alone determines the verb.
Rule 10: “More Than One” — The Counterintuitive Rule
More than one sounds plural. It refers to multiple things. Yet it takes a singular verb.
“More than one student has failed the test.”
However, when more comes before a plural noun, the verb becomes plural:
“More than two students have failed the test.”
Exam Tip: The phrase more than one + singular noun always takes a singular verb. This is one of the most commonly tested quirks in SSC error detection questions.
Rule 11: Nouns That Are Plural in Form but Singular in Meaning
Several nouns end in -s but function as singular because they refer to a single subject, field, or concept.
“Mathematics is compulsory in this school.” “The news is disturbing.” “Economics remains a challenging subject.”
Similar nouns: physics, ethics, genetics, statistics (as a subject), civics, innings (in cricket), means, series, species.
Exam Tip: If you can replace the noun with a single academic subject or a single unit, it is singular. Statistics as a subject = singular. But “The statistics on poverty are alarming” — here statistics means data points, so plural.
Rule 12: Titles, Book Names, and Works of Art
A title is treated as a single entity, regardless of how many words it contains or whether those words appear plural.
“The Chronicles of Narnia is a beloved fantasy series.” “Great Expectations was written by Charles Dickens.” “The Brothers Karamazov remains Dostoevsky’s masterpiece.”
Exam Tip: If a sentence contains a title (book, film, magazine, song), always treat it as singular. The title itself tells you how many things you are referring to — one work.
Rule 13: Distances, Amounts, and Periods of Time
When a distance, weight, amount of money, or period of time is treated as a single unit, it takes a singular verb.
“Twenty kilometres is a long distance to walk.” “Five hundred rupees is not enough for this.” “Three years has passed since she left.”
But when these same measurements refer to individual countable units, the verb becomes plural:
“The last three years have been difficult for the family.” (three separate years)
Rule 14: Relative Pronouns — “Who,” “Which,” “That”
When a relative pronoun (who, which, that) is the subject of a clause, its verb agrees with the antecedent — the noun the pronoun refers back to.
“She is one of those writers who understand their audience.”
Here, who refers to writers — plural. So the verb is understand, not understands.
“She is the only one of those writers who understands her audience.”
Here, who refers to the only one — singular. So the verb is understands.
Exam Tip: This “one of those who” vs. “the only one of those who” distinction appears in advanced grammar sections of CAT and GMAT papers. The antecedent determines everything.
Rule 15: “Many a” Always Takes a Singular Verb
Many a sounds emphatically plural, but grammatically it is singular. It pairs with a singular noun and a singular verb.
“Many a student has failed due to poor time management.” “Many a soldier was lost in that battle.”
Exam Tip: Think of many a as a literary or formal version of “many individual.” Because it emphasises each individual one at a time, it stays singular. Never write “Many a students have…”
Rule 16: Gerunds and Infinitives as Subjects
When a gerund phrase (verb + -ing) or an infinitive phrase acts as the subject of a sentence, the verb is always singular.
“Running every morning improves your cardiovascular health.” “To ignore the warning signs is dangerous.” “Learning new languages takes patience.”
Exam Tip: No matter how long or complex the gerund phrase, treat it as one subject — one thing. Long gerund phrases at the start of sentences are common in IELTS writing tasks and CAT reading comprehension questions.
Rule 17: Expletive Constructions — “There” and “Here”
When a sentence begins with there or here, the grammatical subject comes after the verb. The verb must agree with that postponed subject.
“There is a problem with the software.” (subject: problem — singular) “There are several problems with the software.” (subject: problems — plural) “Here come the results.” (subject: results — plural)
Exam Tip: There and here are not subjects. Never make the verb agree with them. Always scan ahead in the sentence to find the real subject.
Rule 18: Compound Subjects as Accepted Pairs
Certain compound subjects are so closely linked in meaning that they function as a single concept and take a singular verb.
“Law and order is deteriorating.” “Trial and error is the foundation of innovation.” “Slow and steady wins the race.”
This differs from Rule 8 (and = plural) because these pairs are fixed expressions — they express one unified idea, not two separate things.
Exam Tip: The test is meaning. Ask: do these two nouns describe one unified concept or two distinct things? Rice and curry = one dish on the plate = singular. Rice and lentils = two separate food items = plural.
Rule 19: Inverted Sentences — Subject After the Verb
In inverted constructions (questions, sentences beginning with so, neither, nor, or certain literary structures), the verb still must agree with the subject — even when the subject appears after the verb.
“So great were his achievements that history remembers his name.” “Neither does he understand, nor does she care.”
Students often pick the wrong verb form in inverted sentences because they look at the word immediately before the verb rather than finding the true subject.
Exam Tip: Rewrite the sentence in standard word order in your head. Once the subject is back in its natural position, choosing the verb becomes straightforward.
Rule 20: “The + Adjective” Referring to a Class of People
When the is placed before an adjective to refer to a group of people (the poor, the rich, the elderly, the blind, the brave), the expression is always plural.
“The poor are often the last to benefit from policy changes.” “The elderly deserve better healthcare infrastructure.” “The brave stand where others will not.”
Exam Tip: This construction refers not to one poor person but to all poor people collectively — a plural group. The is followed by plural verbs in every standard usage. This distinction matters in IELTS writing task 2 responses and UPSC essay sections.

Common Mistakes Exam Aspirants Make
Mistake 1: Agreeing with the nearest noun, not the true subject
This is the single most frequent error. The noun closest to the verb is not always the subject. Identify the grammatical subject first, regardless of its distance from the verb.
Mistake 2: Treating “either” and “neither” as plural
Many students read neither…nor and automatically pick a plural verb because they associate “neither of two things” with multiplicity. The proximity rule overrides this instinct.
Mistake 3: Using plural verbs with “-ics” nouns
Words like mathematics, physics, and ethics end in -s but always take singular verbs. This surprises students who apply the standard rule for plural nouns.
Mistake 4: Forgetting that “there” is not the subject
“There are a man at the door” is wrong — but students write it because there appears at the start and man feels too far away. The verb agrees with man, not there.
Mistake 5: Applying British English rules in Indian exam contexts
In British English, collective nouns more freely take plural verbs. Indian competitive exams (SSC, UPSC, banking) generally follow American prescriptive grammar, where collective nouns acting as a unit take singular verbs.
Expert Tips to Score Full Marks on SVA Questions
Tip 1: Use the “bracket and isolate” technique
In long sentences, put brackets around all parenthetical phrases. Whatever is inside the brackets is invisible. The verb now clearly faces the subject alone.
Tip 2: When in doubt, return to the base clause
Strip away all subordinate clauses, relative clauses, and prepositional phrases. The skeleton sentence — subject + verb — becomes immediately clear.
Tip 3: Memorise the fixed-singular list as a chunk
Create a mental label: “The MENPS group.” Mathematics, Economics, News, Physics, Statistics (as a subject) — all singular. Attach the label and stop second-guessing.
Tip 4: Practice with error detection, not just fill-in-the-blank
Error detection questions (spot the error, identify the mistake) are harder than fill-in-the-blank because all four options look plausible. Practise SVA specifically in error-detection format, using previous SSC, SBI, and RRB question papers.
Tip 5: Read the sentence aloud — carefully
Your ear often catches agreement errors before your eye does. For exam sections that allow reading, a quiet subvocalization pass can catch agreement errors you missed visually.

Frequently Asked Questions
What is subject-verb agreement in simple terms?
Subject-verb agreement is the rule that the verb in a sentence must match its subject in number and person. A singular subject takes a singular verb form; a plural subject takes a plural verb form. In competitive exams, the challenge is not the rule itself but identifying the true grammatical subject when the sentence is complex or deliberately constructed to mislead.
How do I find the true subject in a difficult sentence?
The most reliable method is to mentally eliminate all phrases between the subject and verb. Prepositional phrases, parenthetical additions (along with, together with, as well as), and subordinate clauses can all be temporarily removed. Whatever remains at the start of the clause — before all those additions — is almost always the true subject.
Does “either/or” always take a singular verb?
No. When both subjects in an either…or or neither…nor construction are singular, the verb is singular. When both are plural, the verb is plural. When they are of different numbers, the verb agrees with the subject that is closer to it. This is called the proximity rule or the rule of the nearer subject.
Why does “a number of” take a plural verb when it seems singular?
The expression a number of functions like several or many. It is an indefinite quantity marker, not a countable entity. So even though the word number is singular, the phrase a number of signals plurality and takes a plural verb. Contrast this with the number of, which refers to a specific, definite total and takes a singular verb.
Is “everyone” singular or plural?
Everyone is always singular in standard English. The same applies to everybody, someone, somebody, anyone, anybody, no one, and nobody. Despite referring to multiple people in meaning, these pronouns are treated as grammatically singular. This is a frequent trap in both multiple-choice grammar questions and error detection tasks.
Can collective nouns take both singular and plural verbs?
Yes. A collective noun takes a singular verb when the group acts as a unified whole. It takes a plural verb when the sentence highlights individual actions or disagreements within the group. In Indian competitive exams, collective nouns functioning as a unit almost always follow singular verb convention unless the sentence specifically describes division among members.
Conclusion
Subject-verb agreement is not a rule you learn once and forget. It is a precision skill that sharpens with every complex sentence you analyse. The examiner’s job is to distract you — with long phrases, misleading nouns, and structures that sound correct but are not.
The 20 rules in this guide cover every significant pattern that appears across SSC CGL, SBI PO, UPSC CSAT, IELTS, CAT, CUET, and IBPS exams. From the proximity rule in either/or constructions to the counterintuitive singular behaviour of many a, each rule here is designed to close a specific gap in your exam preparation.
Go back to the Quick Reference table. Pick three rules you were not confident about before reading this. Write five original sentences for each one. Then find past exam papers and look specifically for subject-verb agreement questions under error detection and sentence improvement. Practice with intention, not just volume.
Grammar rewards the careful reader. And subject-verb agreement rewards the student who has learned to look past the obvious and find the real subject hiding behind the noise.
