Basic English for IELTS: Subject-Verb Agreement
Subject-verb agreement is one of the most important grammar rules in English. It means that the subject and the verb in a sentence must match. When the subject is singular, the verb should usually be singular. When the subject is plural, the verb should usually be plural. This rule may look simple, but many IELTS learners make mistakes with it in speaking and writing.
A strong understanding of subject-verb agreement helps you make correct sentences, avoid common grammar errors, and sound more accurate in English. It is especially useful for IELTS Writing Task 2, IELTS Speaking, and even Reading because it helps you recognise correct sentence patterns more quickly. This lesson works well together with our Basic English for IELTS: Sentence Structure Basics page and our Basic English for IELTS: Parts of Speech guide.
Why Subject-Verb Agreement Matters for IELTS
Subject-verb agreement is more than just a grammar rule. It affects clarity, accuracy, and overall language control. In IELTS Writing, repeated agreement mistakes can reduce the quality of your answer. In IELTS Speaking, they can make your speech sound less natural and less controlled. In IELTS Listening and Reading, understanding subject-verb agreement can help you notice correct answer forms and sentence logic more easily.
For example, compare these two sentences:
- The student studies English every day.
- The student study English every day.
The first sentence is correct because the subject “student” is singular, so the verb “studies” is also singular. The second sentence is incorrect because the verb does not agree with the subject.
These small grammar details matter. A learner who controls subject-verb agreement often writes and speaks with more confidence. To strengthen your grammar foundation further, our IELTS Grammar for Beginners page can help you connect this topic with other basic rules.
What Is Subject-Verb Agreement?
Subject-verb agreement means that the subject and the verb must match in number. In English, this usually means:
- singular subject + singular verb
- plural subject + plural verb
Examples:
- She plays tennis.
- They play tennis.
- My brother works in a bank.
- My brothers work in a bank.
The subject tells us who or what the sentence is about. The verb tells us what action happens or what state exists. When both parts match correctly, the sentence sounds natural and correct.
Singular and Plural Subjects
Before you can apply subject-verb agreement, you must know whether the subject is singular or plural.
Singular subjects
A singular subject refers to one person, place, thing, or idea.
Examples:
- the teacher
- my friend
- the book
- this city
Plural subjects
A plural subject refers to more than one person, place, thing, or idea.
Examples:
- the teachers
- my friends
- the books
- these cities
The verb form usually changes depending on whether the subject is singular or plural.
Examples:
- The teacher speaks clearly.
- The teachers speak clearly.
This rule is one of the most basic but most useful grammar skills in English. It is also closely connected to the structure of sentences, so reviewing our Basic English for IELTS: Sentence Structure Basics lesson can be very helpful.
The Basic Rule of Subject-Verb Agreement
In the present simple tense, singular third-person subjects usually take verbs with -s or -es.
Examples:
- He works.
- She watches.
- It rains.
Plural subjects usually take the base form of the verb.
Examples:
- They work.
- We watch.
- The children play.
This rule is often one of the first grammar patterns that learners should master because it appears very often in everyday English and IELTS answers.
Examples of Correct Subject-Verb Agreement
These are some simple examples:
- The girl runs fast.
- My father drives carefully.
- The students study every evening.
- These shoes are new.
- The book belongs to me.
- The flowers smell beautiful.
Each subject and verb match correctly in number.
Now compare with incorrect examples:
- The girl run fast.
- My father drive carefully.
- The students studies every evening.
- These shoes is new.
These sentences are incorrect because the verb does not agree with the subject.
Subject-Verb Agreement with Be Verbs
The verb “to be” is one of the most important verbs in English. It changes form depending on the subject.
Examples:
- I am happy.
- He is happy.
- She is happy.
- It is cold.
- We are ready.
- They are ready.
This verb is especially common in IELTS speaking and writing. Because it appears so often, learners must use it correctly and confidently.
Incorrect examples:
- He are happy.
- They is ready.
- I is tired.
Correct forms of “be” are essential for clear and accurate English. This is also useful when learning basic pronunciation and sentence rhythm, so our Basic English for IELTS: Pronunciation Basics page can support your practice too.
Subject-Verb Agreement in the Present Simple
The present simple tense is one of the most common areas where agreement mistakes happen.
Examples:
- She studies English.
- He lives in Mersin.
- The bus arrives at 8 o’clock.
Plural subjects use the base verb form:
- They study English.
- We live in Mersin.
- The buses arrive at 8 o’clock.
Many learners forget to add -s to singular third-person verbs. This is a very common error, but it can be fixed with regular practice.
Subject-Verb Agreement with Compound Subjects
A compound subject contains two or more subjects joined by and, or, or nor. The verb form depends on how the subjects are connected.
Subjects joined by and
When two subjects are joined by and, the subject is usually plural.
Examples:
- Ali and Ahmad are friends.
- The teacher and the student were late.
- My mother and father work in the same school.
Subjects joined by or / nor
When subjects are joined by or or nor, the verb usually agrees with the nearest subject.
Examples:
- My brother or my parents are coming.
- My parents or my brother is coming.
This rule can feel difficult at first, but it becomes easier with practice. Always look carefully at the actual subject closest to the verb.
Subject-Verb Agreement with Uncountable Nouns
Uncountable nouns usually take singular verbs because they are treated as one whole idea.
Examples:
- Information is important.
- Furniture is expensive.
- Advice is useful.
- The news is surprising.
Even though these words may look like they refer to many ideas, they are grammatically singular in English.
Incorrect:
- Information are important.
- Advice are useful.
Correct:
- Information is important.
- Advice is useful.
This rule is very useful in IELTS Writing because academic topics often include uncountable nouns such as information, research, knowledge, and education.
Subject-Verb Agreement with Collective Nouns
Collective nouns refer to a group of people or things. In many cases, they take singular verbs when the group is seen as one unit.
Examples:
- The team is strong.
- The class is quiet.
- The family lives nearby.
Sometimes, especially in British English, a collective noun can take a plural verb when the focus is on the individuals in the group.
Example:
- The team are wearing their new uniforms.
For IELTS learners, it is usually safest to follow the style and consistency of the sentence you are writing. When in doubt, keep the grammar clear and simple.
Subject-Verb Agreement with Indefinite Pronouns
Some indefinite pronouns are singular, while others are plural.
Singular indefinite pronouns
Examples:
- everyone
- somebody
- anyone
- nobody
- each
- every
These usually take singular verbs:
- Everyone is ready.
- Somebody knows the answer.
- Each student has a book.
Plural indefinite pronouns
Examples:
- both
- few
- many
- several
These usually take plural verbs:
- Many students are absent.
- Both answers are correct.
- Several people were waiting.
Pronouns that depend on context
Some words such as all, some, more, and most can be singular or plural depending on the noun they refer to.
Examples:
- Some of the water is cold.
- Some of the students are absent.
This area often confuses learners, so careful reading is important.
Subject-Verb Agreement with There Is and There Are
The verb agrees with the noun that comes after “there is” or “there are.”
Examples:
- There is a book on the table.
- There are two books on the table.
- There is a problem.
- There are many problems.
This structure is common in both speaking and writing, especially when describing places, situations, and data.
Subject-Verb Agreement with Noun Phrases
Sometimes the subject is a long noun phrase. In this case, find the main noun to decide the correct verb.
Examples:
- The list of students is on the table.
- The group of visitors was late.
- The boxes of books are heavy.
The main subject here is list, group, and boxes, not the words after of. This is a common point of confusion for learners.
Subject-Verb Agreement with Measurements, Time, and Distance
Expressions of time, money, distance, and measurement are often singular when they express one whole amount.
Examples:
- Ten dollars is enough.
- Five years is a long time.
- Two kilometres is not far.
- Twenty minutes is enough for me.
This can feel unusual because the words look plural, but the expression is treated as one unit.
Common Subject-Verb Agreement Mistakes IELTS Learners Make
Many students repeat the same errors. Recognising them early makes improvement much easier.
1. Forgetting -s with singular subjects
Incorrect:
- She speak English.
Correct:
- She speaks English.
2. Using singular verbs with plural subjects
Incorrect:
- The students studies every day.
Correct:
- The students study every day.
3. Misunderstanding collective nouns
Incorrect:
- The team are strong.
This may be possible in some varieties of English, but for IELTS clarity it is often safer to write: - The team is strong.
4. Confusing uncountable nouns
Incorrect:
- Advice are helpful.
Correct:
- Advice is helpful.
5. Choosing the wrong verb with “there is / there are”
Incorrect:
- There is many reasons.
Correct:
- There are many reasons.
6. Getting lost in long subjects
Incorrect:
- The picture of the mountains are beautiful.
Correct:
- The picture of the mountains is beautiful.
When your subject is long, always identify the main noun before choosing the verb.
How to Check Subject-Verb Agreement Quickly
A simple checking method can help you avoid mistakes in writing.
First, find the subject. Second, decide whether it is singular or plural. Third, look at the main verb. Fourth, check whether the verb matches the subject.
Example:
- The teacher explains the lesson.
Subject: teacher
Number: singular
Verb: explains
Agreement: correct
Example:
- The teachers explains the lesson.
Subject: teachers
Number: plural
Verb: explains
Agreement: incorrect
This habit is very useful when proofreading IELTS Writing answers under time pressure.
How Subject-Verb Agreement Helps IELTS Writing
In IELTS Writing, grammar accuracy is very important. If you make repeated subject-verb agreement errors, your sentence control may look weak. Even if your ideas are good, simple grammar mistakes can reduce the overall quality of your answer.
Good subject-verb agreement helps you write with more confidence and clarity. It also supports better sentence variety because you can build both simple and complex sentences without grammar errors. For learners who are still developing this area, revisiting Basic English for IELTS: Sentence Structure Basics is a smart next step.
How Subject-Verb Agreement Helps IELTS Speaking
In IELTS Speaking, you do not have much time to think about grammar. That is why subject-verb agreement must become automatic. The more often you practise correct sentence patterns, the more naturally they will come out in conversation.
Examples:
- My brother lives in Istanbul.
- My parents work near the city centre.
- The weather is very hot today.
These sentences are simple, but they are accurate and clear. That is exactly what IELTS speaking requires. You do not need to speak with very complex grammar all the time. You need to speak correctly, clearly, and naturally.
Best Ways to Practise Subject-Verb Agreement
The best practice is short, regular, and focused. Read a sentence and ask yourself: Is the subject singular or plural? Then choose the correct verb. Over time, this becomes automatic.
A useful exercise is to take one subject and change it from singular to plural.
Examples:
- The student studies English.
- The students study English.
- The teacher is helpful.
- The teachers are helpful.
- My friend likes coffee.
- My friends like coffee.
This kind of practice helps you notice grammar patterns more quickly.
You can also practise by reading short texts and underlining all the subjects and verbs. This builds awareness and helps you recognise agreement naturally. If you are also improving word forms and sentence building, our Basic English for IELTS: Parts of Speech page can support your study.
Tips for Learning Subject-Verb Agreement
Subject-verb agreement is one of the simplest grammar rules in English, but it is also one of the most important. Mastering it helps you avoid common mistakes and improves your accuracy in both speaking and writing. Focus first on basic present simple sentences, then move to compound subjects, uncountable nouns, collective nouns, and special expressions such as there is and there are.
Do not try to memorise everything at once. Learn the pattern, practise a little every day, and check your sentences carefully. Strong grammar starts with strong basics, and subject-verb agreement is one of the most valuable basics for IELTS success.
