7. Subject–Verb Agreement Deep Dive

Subject–verb agreement is the single most exam-relevant topic in this entire guide, and it is relevant precisely because it is rule-based rather than idiom-based: once you know the rule, you can apply it to a sentence you have never seen before, which is exactly the skill an error-spotting question is designed to test. Tense errors require you to track meaning across a whole sentence; agreement errors are frequently visible in a five-word span once you know where to look. The thirty-plus rules below are organized from the most basic to the most exam-specific, and every rule carries two original wrong/fix pairs so you can see the error in two different sentence shapes.

It is worth pausing on why agreement errors are so cheap for examiners to write and so easy for candidates to miss. A well-built agreement question does not usually need an obscure verb or an unusual tense — it needs only a subject whose grammatical number is disguised in some way, and a verb form placed close enough to a distracting noun that a fast reader matches the verb to the wrong word. That disguise takes a handful of recurring shapes: a quantity phrase like "a number of" that looks plural but might not be, a long prepositional phrase wedged between the true subject and its verb, a noun that is plural in spelling but singular in meaning, or a pronoun like "each" or "neither" that is grammatically singular even though its real-world reference is a group of people. None of these tricks require advanced vocabulary or unusual sentence structure, which is exactly why they show up so often and so cheaply across SSC, Bank, and Railway papers — they are inexpensive to write and reliably catch candidates who read for meaning rather than for grammatical structure. Learning to notice the shape of the disguise, rather than memorizing each sentence individually, is what turns this section from thirty-two isolated facts into one transferable skill.

Rule 1 — A collective noun used as a single unit takes a singular verb. When a group (team, committee, jury, family, government, class) is being described as one undivided body, it behaves like a singular noun. Wrong: The committee have decided to postpone the meeting. Fix: The committee has decided to postpone the meeting. Wrong: Our cricket team play very well together. Fix: Our cricket team plays very well together.

Rule 2 — A collective noun used to mean its individual members takes a plural verb. When the sentence emphasizes the members acting separately rather than the group acting as one, the plural is correct, though this pattern is far rarer in Indian competitive exams than Rule 1. Wrong: The jury is divided in their opinions on the verdict. Fix: The jury are divided in their opinions on the verdict. Wrong: The staff was arguing among themselves about the new policy. Fix: The staff were arguing among themselves about the new policy.

Rule 3 — "A number of" + plural noun takes a plural verb. Here "a number of" functions as a quantifier meaning "several," so the verb agrees with the plural noun that follows it, not with "number." Wrong: A number of students has failed to submit their assignments. Fix: A number of students have failed to submit their assignments. Wrong: A number of complaints was received by the office yesterday. Fix: A number of complaints were received by the office yesterday.

Rule 4 — "The number of" + plural noun takes a singular verb. Here "number" itself is the true subject — a single countable quantity — and the following plural noun merely describes what is being counted. Wrong: The number of accidents on this road have increased sharply. Fix: The number of accidents on this road has increased sharply. Wrong: The number of unemployed graduates are rising every year. Fix: The number of unemployed graduates is rising every year.

Rule 5 — Two or more subjects joined by "and" normally take a plural verb. When "and" joins two distinct singular subjects into a combined subject, the verb must be plural. Wrong: Ramesh and his brother is going to the market. Fix: Ramesh and his brother are going to the market. Wrong: The manager and the accountant was present at the audit. Fix: The manager and the accountant were present at the audit.

Rule 6 — When two singular subjects joined by "and" refer to one person, one thing, or one combined idea, the verb stays singular. This is the exception exam-setters love, because it looks identical to Rule 5 on the surface. Wrong: The Chairman and Managing Director are addressing the shareholders today. (if it is one person holding both titles) Fix: The Chairman and Managing Director is addressing the shareholders today. Wrong: Bread and butter are her usual breakfast. Fix: Bread and butter is her usual breakfast.

Rule 7 — Subjects joined by "or" or "nor" take a verb that agrees with the nearer subject. Unlike "and," these connectors do not combine the subjects; the verb simply matches whichever subject sits closest to it. Wrong: Neither the teacher nor the students was informed about the change. Fix: Neither the teacher nor the students were informed about the change. Wrong: Either the manager or his assistants is responsible for this error. Fix: Either the manager or his assistants are responsible for this error.

Rule 8 — "Either...or" and "neither...nor" joining two singular subjects take a singular verb. When both linked subjects are singular, there is no ambiguity: the verb is singular regardless of which subject the exam places closer to the verb. Wrong: Either Rahul or his friend are coming to the party. Fix: Either Rahul or his friend is coming to the party. Wrong: Neither the pen nor the pencil work properly. Fix: Neither the pen nor the pencil works properly.

Rule 9 — Indefinite pronouns such as everyone, everybody, everything, someone, somebody, anyone, anybody, no one, nobody, and each are always singular. These words feel plural in meaning because they refer to a group, but grammatically each one is a singular pronoun and always takes a singular verb. Wrong: Everyone in the office are expected to attend the training. Fix: Everyone in the office is expected to attend the training. Wrong: Nobody know the correct answer to this question. Fix: Nobody knows the correct answer to this question.

Rule 10 — "Each of," "every one of," and "either of" + plural noun still take a singular verb. The word immediately before the verb may be plural, but the true grammatical subject is the singular quantifier "each," "either," or "every one," not the noun in the "of" phrase. Wrong: Each of the candidates were given ten minutes to prepare. Fix: Each of the candidates was given ten minutes to prepare. Wrong: Every one of these machines need urgent servicing. Fix: Every one of these machines needs urgent servicing.

Rule 11 — "None" is traditionally treated as singular ("not one"), though modern usage allows a plural verb when the sense is clearly "not any." In competitive exams, the safer and more frequently rewarded choice is the singular verb, unless the sentence unmistakably refers to multiple countable items acting separately. Wrong: None of the passengers has left the train yet. (context implies multiple passengers acting individually — plural is intended here) Fix: None of the passengers have left the train yet. Wrong: None of the milk are spoiled. Fix: None of the milk is spoiled.

Rule 12 — With fractions, percentages, and words like "half," "most," "some," "all," and "a lot," the verb agrees with the noun that follows "of," not with the fraction word itself. This single rule covers a large share of "select the correct verb" questions because it applies to so many different quantity expressions. Wrong: Fifty percent of the workers was absent today. Fix: Fifty percent of the workers were absent today. Wrong: Half of the cake have already been eaten. Fix: Half of the cake has already been eaten.

Rule 13 — Uncountable (mass) nouns such as advice, information, furniture, luggage, news, and equipment always take a singular verb. These nouns have no plural form in standard usage, and learners who mentally translate from languages that do pluralize equivalent words often produce this error. Wrong: The information provided in the report were incorrect. Fix: The information provided in the report was incorrect. Wrong: Her advice on career choices are always practical. Fix: Her advice on career choices is always practical.

Rule 14 — Certain nouns that end in "-s" and look plural are actually singular in meaning, including news, mathematics, physics, economics, ethics, athletics, and measles. The final "-s" is a leftover of the word's etymology, not a plural marker, so the verb must be singular. Wrong: Mathematics are my favourite subject. Fix: Mathematics is my favourite subject. Wrong: The news about the merger were shocking to investors. Fix: The news about the merger was shocking to investors.

Rule 15 — Titles of books, films, organizations, and countries that are plural in form still take a singular verb, because the title refers to one single work or entity. This rule surfaces occasionally in reading-comprehension-adjacent grammar questions. Wrong: "The Three Musketeers" are a classic adventure novel. Fix: "The Three Musketeers" is a classic adventure novel. Wrong: The United Nations were founded in 1945. Fix: The United Nations was founded in 1945.

Rule 16 — Expressions of distance, money, time, and weight are treated as one single amount and take a singular verb, even though they contain a plural noun. The sentence is measuring a single quantity, not counting separate items. Wrong: Five kilometers are a long distance to walk in this heat. Fix: Five kilometers is a long distance to walk in this heat. Wrong: Two thousand rupees were enough to cover the expenses. Fix: Two thousand rupees was enough to cover the expenses.

Rule 17 — "There is / there are" and "here is / here are" must agree with the noun that follows, not with "there" or "here," since these words are not the grammatical subject. Because the true subject appears after the verb, learners often default to whichever form feels most natural to say first. Wrong: There is many reasons to doubt his story. Fix: There are many reasons to doubt his story. Wrong: Here comes the winners of the competition. Fix: Here come the winners of the competition.

Rule 18 — A phrase beginning with "with," "together with," "as well as," "along with," "accompanied by," "in addition to," or "besides" does not change the number of the main subject. These phrases add information but are grammatically parenthetical, so the verb still agrees only with the original subject. Wrong: The principal, along with the teachers, are attending the seminar. Fix: The principal, along with the teachers, is attending the seminar. Wrong: The player, as well as his coach, were fined by the board. Fix: The player, as well as his coach, was fined by the board.

Rule 19 — In a relative clause, the verb after "who," "which," or "that" agrees with the antecedent noun the clause modifies, not with any noun that happens to sit closer to it. Locating the real antecedent — sometimes several words earlier in the sentence — is the whole difficulty of this rule. Wrong: He is one of the few managers who takes genuine interest in his team. (see Rule 20 for why this needs the plural) Fix: He is one of the few managers who take genuine interest in their team. Wrong: This is a list of items that needs to be replaced. Fix: This is a list of items that need to be replaced.

Rule 20 — "One of the + plural noun + who/that" takes a plural verb in the relative clause, because the clause describes the whole group, not the single "one." This is one of the most consistently mis-set traps in SSC and Bank error-spotting papers. Wrong: She is one of the students who has scored above ninety percent. Fix: She is one of the students who have scored above ninety percent. Wrong: This is one of the reasons that explains his resignation. Fix: This is one of the reasons that explain his resignation.

Rule 21 — "The only one of the + plural noun + who/that" reverses Rule 20 and takes a singular verb, because "only" restricts the meaning back down to the single individual. Exam-setters place Rule 20 and Rule 21 next to each other specifically to test whether a candidate is matching the surface pattern or actually reading the sentence. Wrong: He is the only one of the players who have qualified for the finals. Fix: He is the only one of the players who has qualified for the finals. Wrong: She is the only one of my friends who understand this problem. Fix: She is the only one of my friends who understands this problem.

Rule 22 — "Many a" + singular noun takes a singular verb, even though the overall meaning is plural. This slightly archaic but exam-favourite construction always uses a singular noun and singular verb by fixed grammatical convention. Wrong: Many a student have failed this difficult examination. Fix: Many a student has failed this difficult examination. Wrong: Many a soldier were wounded in that battle. Fix: Many a soldier was wounded in that battle.

Rule 23 — "A lot of," "lots of," "plenty of," "some," "most," and "all" agree with the noun that follows "of," exactly like Rule 12's fractions. These quantifiers have no fixed number of their own; they simply inherit the number of whatever they are quantifying. Wrong: A lot of effort were put into organizing this event. Fix: A lot of effort was put into organizing this event. Wrong: Most of the books in the library needs repair. Fix: Most of the books in the library need repair.

Rule 24 — In an inverted sentence, where the verb precedes the subject, the verb still agrees with the subject that follows it. Question order and certain formal constructions ("Never had I seen...," "Down came the rain") reverse the usual word order but not the underlying agreement rule. Wrong: Rarely has the students seen such heavy rainfall in June. Fix: Rarely have the students seen such heavy rainfall in June. Wrong: Never before was such strict measures taken by the administration. Fix: Never before were such strict measures taken by the administration.

Rule 25 — When a subject is followed by "rather than" or "no less than" plus another noun, the verb agrees with the first (main) subject only, treating the phrase after "rather than" as parenthetical, similar to Rule 18. Wrong: The coach, rather than the players, are to blame for the loss. Fix: The coach, rather than the players, is to blame for the loss. Wrong: The manager, no less than his subordinates, have to follow the rules. Fix: The manager, no less than his subordinates, has to follow the rules.

Rule 26 — A gerund phrase used as the subject of a sentence always takes a singular verb, because the whole phrase is functioning as one abstract noun-idea, not as multiple items. Wrong: Reading books on a wide range of subjects broaden the mind. Fix: Reading books on a wide range of subjects broadens the mind. Wrong: Solving these complicated equations require a great deal of patience. Fix: Solving these complicated equations requires a great deal of patience.

Rule 27 — An infinitive phrase used as the subject also always takes a singular verb, for the same reason as Rule 26. Wrong: To finish this project on time seem impossible now. Fix: To finish this project on time seems impossible now. Wrong: To follow all these instructions carefully take considerable discipline. Fix: To follow all these instructions carefully takes considerable discipline.

Rule 28 — A noun clause beginning with "what," "that," or "whatever" used as the subject of a sentence takes a singular verb, treating the whole clause as one single idea. Wrong: What the committee decided today were final and binding. Fix: What the committee decided today was final and binding. Wrong: That he lied to the investigators surprise nobody in the office. Fix: That he lied to the investigators surprises nobody in the office.

Rule 29 — Plural-form nouns that name a single country, organization, or body of work take a singular verb, just as with titles in Rule 15, because they name one entity even though the word ends in "-s." Wrong: The Philippines are known for its beautiful beaches. Fix: The Philippines is known for its beautiful beaches. Wrong: Great Expectations remain one of Dickens's most celebrated novels. (this particular sentence is actually already correct if read as "the novels remain," so watch for the reverse trap: singular titles wrongly given plural verbs) Fix: Great Expectations remains one of Dickens's most celebrated novels.

Rule 30 — Pair nouns like "scissors," "trousers," "spectacles," "jeans," and "pliers" take a plural verb on their own, but switch to a singular verb once "a pair of" is placed in front of them. The bare pair noun and the "a pair of" phrase follow opposite agreement rules, which is exactly what makes this pattern exam-worthy. Wrong: My scissors is missing from the drawer again. Fix: My scissors are missing from the drawer again. Wrong: A pair of trousers were hanging on the line. Fix: A pair of trousers was hanging on the line.

Rule 31 — When two subjects are qualified by "each" or "every" placed before them and joined by "and," the verb remains singular, because "each" and "every" distribute the action to one item at a time. Wrong: Each boy and each girl in the class were given a certificate. Fix: Each boy and each girl in the class was given a certificate. Wrong: Every teacher and every student have a role to play in this initiative. Fix: Every teacher and every student has a role to play in this initiative.

Rule 32 — Words like "physics," "economics," and similar "-ics" subject names take a singular verb when referring to the field of study, but the same word can take a plural verb when it refers instead to a set of practical characteristics or tactics. This dual behavior is a genuine subtlety, and exams test the more common singular sense far more often. Wrong: Statistics is a collection of numerical facts gathered for this report. (here "statistics" means the individual data points, a plural sense) Fix: Statistics are a collection of numerical facts gathered for this report. Wrong: Economics study how societies allocate scarce resources. Fix: Economics studies how societies allocate scarce resources.
