Subject-Verb Agreement10 Rules That Examiners Always Test
The single most tested grammar area in SSC CGL, CHSL, UPSC, IELTS, and TOEFL. Master every trap — proximity, collective nouns, indefinite pronouns, and fractional expressions.
📌 Why This Topic Is Tested
Subject-verb agreement errors account for more lost marks in competitive English papers than any other single grammar topic. The rules are deceptively simple in isolation — every candidate knows that 'he is' and 'they are' — but examiners systematically design sentences that use intervening phrases, inverted structures, and misleading plural-looking singular nouns to override your instinct and force the wrong answer. Understanding the mechanisms behind each trap is the only reliable defence.
⚠️ High-Yield Exam Facts
- ▸ SSC CGL Tier-I has 2–5 subject-verb agreement questions in every paper across Error Spotting and Sentence Improvement.
- ▸ The Proximity Trap (neither/nor, either/or) is tested in at least 80% of SSC papers.
- ▸ Collective noun questions appear in UPSC, CAT, and IELTS equally — singular vs. plural usage differences between British and American English are specifically tested.
- ▸ The 'A number of vs. The number of' distinction is one of the three most repeated traps across all Indian competitive exams.
- ▸ IELTS Writing Task 2 is penalised directly for subject-verb agreement errors in the grammatical range and accuracy band.
🎯 10 Core Rules — Subject-Verb Agreement
The Proximity Trap (Neither / Either … Or / Nor)
When two subjects are joined by 'either … or' or 'neither … nor', the verb agrees with the subject that is closest to it — not the first one. This is called the rule of proximity.
❌ Incorrect
“Neither the teacher nor the students was present in the examination hall.”
✅ Correct
“Neither the teacher nor the students were present in the examination hall.”
Exam Trap Tip
Exams deliberately place a singular noun first and a plural noun directly before the verb. Your eye drifts back to 'teacher' and selects 'was'. Always identify the subject closest to the verb before choosing the verb form.
The Collective Noun Illusion
Collective nouns (team, committee, jury, class, family, staff, government) take a singular verb when the group acts as one united body, and a plural verb when the members act individually. In formal exam English (especially British-style papers), the singular form is the default safe answer unless individual action is clearly implied.
❌ Incorrect
“The committee have reached a unanimous decision after the meeting.”
✅ Correct
“The committee has reached a unanimous decision after the meeting.”
Exam Trap Tip
The trick is that both forms can appear 'correct' depending on context. Exam setters test whether you know the 'united body = singular' rule. Look for words like 'unanimous', 'together', or 'jointly' as signals that singular is required.
The Intervening Phrase Distractor
Phrases that come between the subject and the verb — such as prepositional phrases (of, along with, together with, as well as, in addition to, including) — do not change the number of the true subject. The verb must still agree with the original subject before the phrase.
❌ Incorrect
“The quality of the products manufactured in these factories are very poor.”
✅ Correct
“The quality of the products manufactured in these factories is very poor.”
Exam Trap Tip
The phrase 'of the products manufactured in these factories' is a distractor. The true subject is 'quality' (singular). Exams insert long prepositional phrases between the subject and verb precisely to make you forget what the real subject was. Always bracket the intervening phrase mentally and test agreement without it.
The Indefinite Pronoun Rule (Each, Every, Either, Neither)
Indefinite pronouns — each, every, either, neither, one, anyone, everyone, someone, no one, nobody, everybody, somebody — always take a singular verb, regardless of any plural nouns that follow them. This applies even when 'each' or 'every' precedes a compound subject joined by 'and'.
❌ Incorrect
“Each of the students in the three batches were given a separate question paper.”
✅ Correct
“Each of the students in the three batches was given a separate question paper.”
Exam Trap Tip
The plural noun 'students' immediately before the verb is the deliberate trap. Remember the mnemonic: 'Each, Every, Either, Neither — these four are always singular forever.' Also watch for 'Every boy and every girl has…' — two 'every' phrases joined by 'and' still take a singular verb.
The Inverted Sentence Trap (There is / There are)
In sentences beginning with 'There' or 'Here', the true subject comes after the verb. The verb must agree with that delayed subject, not with the word 'there' or 'here'. When a compound subject follows, the verb agrees with the first element of the compound.
❌ Incorrect
“There is a pen, two notebooks, and a ruler on the examination desk.”
✅ Correct
“There are a pen, two notebooks, and a ruler on the examination desk.”
Exam Trap Tip
Students see 'There is' and automatically accept it as correct because it sounds natural in speech. Exams exploit this by hiding a plural or compound subject after the verb. Always flip the sentence in your head: 'A pen, two notebooks, and a ruler are on the desk' — now the agreement error becomes obvious.
The 'Along With / Together With' Phantom Plural
Phrases joined to the subject by 'along with', 'together with', 'as well as', 'in addition to', 'besides', 'except', 'with', or 'accompanied by' do NOT create a compound subject. The main subject before these connectors remains the sole controller of verb number. These connectors are parenthetical — they can be removed without changing the sentence's core meaning.
❌ Incorrect
“The director, along with all the senior managers, were present at the emergency board meeting.”
✅ Correct
“The director, along with all the senior managers, was present at the emergency board meeting.”
Exam Trap Tip
The plural phrase 'all the senior managers' is inserted specifically to trigger a plural verb. Mentally erase everything between the commas: 'The director … was present' — now the correct form is obvious. This rule is tested in nearly every competitive paper because the incorrect version sounds natural in spoken English.
The Fractional Expression Rule (A Number Of vs. The Number Of)
'A number of' means 'several' and takes a plural verb because the emphasis is on many individual items. 'The number of' refers to a specific count — a singular concept — and takes a singular verb. Fractions and percentages follow the noun that comes after 'of': 'Half of the water is gone' (uncountable) vs 'Half of the bottles are broken' (countable plural).
❌ Incorrect
“The number of applications received for the post have increased sharply this year.”
✅ Correct
“The number of applications received for the post has increased sharply this year.”
Exam Trap Tip
The trigger word 'applications' (plural) is placed between 'number' and the verb to lure you into choosing 'have'. Remember: 'The number' = singular concept = singular verb. 'A number' = several = plural verb. Write the pair on a flashcard and test yourself.
The Mathematical Expression Agreement
Arithmetic operations stated in sentence form follow special rules: addition ('and'), subtraction ('from'), and multiplication ('times') treat the result as singular when the numbers are small and stated together as a single unit. Division results are typically singular. However, when numbers are listed separately with 'and', they may take a plural verb. In exams, sums expressed as subjects ('Two and two', 'Four times five') always take a singular verb.
❌ Incorrect
“Two and two are four, which is why mathematics form the basis of logic.”
✅ Correct
“Two and two is four, which is why mathematics forms the basis of logic.”
Exam Trap Tip
Both errors are in one sentence: (1) 'Two and two are' should be 'is' — the sum is a single value. (2) 'Mathematics' is a singular noun despite ending in -s, just like physics, economics, ethics, and news. These '-ics' subject nouns always take singular verbs in academic/formal contexts.
The Relative Clause Agreement Trap (Who / Which / That)
When a relative pronoun (who, which, that) is the subject of a relative clause, its verb must agree with the pronoun's antecedent — the noun it refers to. This is especially tricky in 'one of those who/that' constructions, where the antecedent of 'who' is the plural noun, not 'one'.
❌ Incorrect
“She is one of those dedicated officers who never shirks her responsibilities.”
✅ Correct
“She is one of those dedicated officers who never shirk their responsibilities.”
Exam Trap Tip
The antecedent of 'who' is 'officers' (plural), not 'one' (singular). The phrase means: among those dedicated officers who never shirk. Exams disguise this by making the sentence feel like it is about 'one person', which pulls you toward a singular verb. Always identify what 'who' refers back to before selecting the verb.
The Plural-Form Singular Noun Trap
Several nouns ending in -s appear to be plural but are grammatically singular and must take singular verbs. These include: news, mathematics, physics, economics, politics, ethics, aesthetics, genetics, athletics, measles, mumps, rickets, billiards, and darts. Conversely, some nouns look singular but are always treated as plural: police, people, cattle, poultry, gentry, clergy.
❌ Incorrect
“The latest news about the merger negotiations are expected to be released tomorrow morning.”
✅ Correct
“The latest news about the merger negotiations is expected to be released tomorrow morning.”
Exam Trap Tip
The word 'negotiations' (plural) between 'news' and the verb is the classic intervening-phrase trap combined with the plural-form noun trap — two tricks in one question. Any time you see 'news', lock in a singular verb immediately. For 'police' and 'people', do the opposite — always use plural.
⚠️ Examiner Traps & Elimination Hacks
🚨 Trap Type 1 — The Intervening Phrase Distractor
A long prepositional phrase is inserted between the subject and verb to make you forget the true subject. Always identify and mentally bracket the phrase, then test agreement without it.
❌ Wrong: “The list of items required for the examination are given below.”
✅ Correct: “The list of items required for the examination is given below.”
⚡ Trap Type 2 — Plural-Form Singular Nouns
Nouns ending in -s that name a single discipline, disease, or game take singular verbs: news, mathematics, physics, economics, ethics, measles, mumps, billiards, darts. Exams place a plural verb after these to create the error.
❌ Wrong: “The news about the floods are distressing.”
✅ Correct: “The news about the floods is distressing.”
🎯 Elimination Framework — 3 Steps
Step 1: Identify the true grammatical subject — not the nearest noun, but the head noun of the subject phrase. Step 2: Determine its grammatical number (singular/plural). Step 3: Select the verb form that matches. Ignore everything between subject and verb when making the agreement decision.
