1. What is Subject–Verb Agreement?

In simple words:

The subject and the verb in a sentence must agree in number and person.

Number means:

Singular → one person or thing
Plural → more than one person or thing

Compare:

Subject	Verb	Example
He	works	He works hard.
She	studies	She studies English.
They	work	They work hard.
We	study	We study English.

Easy Memory Trick

One → singular verb
More than one → plural verb

But remember: English verbs have some special patterns, so this rule is not always as simple as adding or removing -s.

2. Why is Subject–Verb Agreement Important?

Correct subject–verb agreement makes your English:

Grammatically correct
Clearer
More natural
Easier to understand
More professional

It is especially important in:

Spoken English
Writing
Exams
Interviews
Emails
Workplace communication
Presentations

3. The Basic Rule

With the simple present tense, singular third-person subjects generally take a verb ending in -s/-es.

Singular Subject → Verb + s/es

He plays cricket.
She works in Bhubaneswar.
Rahul studies every evening.
The dog barks loudly.

Plural Subject → Base Verb

They play cricket.
We work in Bhubaneswar.
Rahul and Amit study together.
The dogs bark loudly.

Remember

He / She / It → usually verb + s/es
I / We / You / They → base verb

Examples:

I work.
You work.
We work.
They work.
He works.
She works.
It works.

4. Rule: Singular Subject Takes a Singular Verb

A singular subject usually requires a singular verb.

Examples

The boy plays football.
My sister likes music.
The teacher explains the lesson.
This computer works well.
The bus arrives at 8 a.m.

Incorrect vs Correct

❌ Incorrect	✅ Correct
He work hard.	He works hard.
She like coffee.	She likes coffee.
The boy play cricket.	The boy plays cricket.
My friend live here.	My friend lives here.

5. Rule: Plural Subjects Take a Plural Verb

Plural subjects generally take the base form of the verb in the simple present tense.

The students study English.
The teachers teach well.
My friends live in Cuttack.
The children play outside.

Compare

The student studies English.
The students study English.
The teacher teaches English.
The teachers teach English.

6. The Special Case of “I” and “You”

Although I refers to one person, we use the base form of the verb.

I work here. ✅
I works here. ❌

Although you can refer to one person or several people, we use the base form.

You work hard. ✅
You works hard. ❌

Remember

I and You take the base verb.

7. Two Subjects Joined by “And”

When two subjects are joined by and, they generally form a plural subject.

Structure

Subject + and + Subject + plural verb

Examples:

Rahul and Amit are friends.
My brother and sister live in Cuttack.
Tea and coffee are available.
The teacher and students are in the classroom.

Incorrect vs Correct

❌ Rahul and Amit is friends.
✅ Rahul and Amit are friends.

8. Subjects Joined by “Or” or “Nor”

When subjects are joined by or, nor, either…or, neither…nor, the verb generally agrees with the subject closest to it.

Examples

Either Rahul or Amit is coming.
Either the teacher or the students are responsible.
Neither the manager nor the employees are available.
Neither the employees nor the manager is available.

Easy Tip

With or/nor, look at the subject nearest to the verb.

9. “Each” and “Every” Take a Singular Verb

Each and every are followed by a singular noun and take a singular verb.

Each student has a notebook.
Every student needs an ID card.
Each employee works hard.
Every child likes stories.

❌ Every student have a book.
✅ Every student has a book.

Remember

Each = one at a time
Every = all individually

So use a singular verb.

10. “Everyone”, “Everybody”, “Someone”, etc.

Words ending in -one, -body, and -thing are generally treated as singular.

Examples:

Everyone is ready.
Everybody likes music.
Someone has called you.
Nobody knows the answer.
Everything looks good.

Common Mistake

❌ Everyone are ready.
✅ Everyone is ready.

11. “There Is” and “There Are”

The verb agrees with the noun that comes after it.

Singular

There is a book on the table.
There is a student in the classroom.
There is a problem.

Plural

There are two books on the table.
There are many students in the classroom.
There are several problems.

Easy Tip

Look at the noun after there is/there are.

12. Collective Nouns

Words such as:

Team
Family
Committee
Group
Class
Government
Staff

can refer to a group as one unit.

In standard English, when the group is treated as a single unit, use a singular verb.

The team is ready.
My family is happy.
The committee has decided.
The class is quiet.

In some varieties of English, especially British English, collective nouns can also take plural verbs when the members are being considered individually:

The team are wearing their new uniforms.

For learners, use a singular verb when the group is treated as one unit.

13. Uncountable Nouns Usually Take Singular Verbs

Uncountable nouns generally take singular verbs.

Examples:

Water is essential.
Information is useful.
Furniture is expensive.
Advice is helpful.
Money is important.

Common Mistakes

❌ The information are useful.
✅ The information is useful.

❌ The furniture are new.
✅ The furniture is new.

14. Don’t Be Confused by Words Between the Subject and Verb

Sometimes extra words come between the subject and the verb.

Find the real subject.

Example

The box of chocolates is on the table.

The subject is box, not chocolates.

So:

✅ The box of chocolates is on the table.

Not:

❌ The box of chocolates are on the table.

Another example:

The students in my class are hardworking.

The subject is students, so:

✅ The students in my class are hardworking.

15. Subject–Verb Agreement with “Who”

The verb after who generally agrees with the noun that who refers to.

She is the person who helps me.
They are the people who help me.

Compare:

Singular:
She is a teacher who works here.

Plural:
They are teachers who work here.

16. Subject–Verb Agreement with “One of”

After one of + plural noun, the main verb is generally singular because the subject is one.

One of my friends is a doctor.
One of the students has completed the assignment.
One of the books is missing.

❌ One of my friends are a doctor.
✅ One of my friends is a doctor.

17. Amounts of Time, Money and Distance

When an amount is considered as one unit, we normally use a singular verb.

Ten kilometres is a long distance.
Five years is a long time.
₹1,000 is enough for the trip.
Two hours is sufficient.

But when we are talking about individual units, the meaning can change:

Ten kilometres are marked on the map.
(individual kilometres/sections are being referred to)

The meaning determines the agreement.

18. “A Number of” vs “The Number of”

This is a very important rule.

A number of + plural noun → plural verb

A number of students are absent.
A number of people have applied.

The number of + plural noun → singular verb

The number of students is increasing.
The number of applicants has increased.

Memory Trick

A number of → many → plural verb
The number of → the total → singular verb

19. Subjects That Look Plural but Are Singular

Some nouns end in -s but are treated as singular.

Examples:

Mathematics is interesting.
Physics is difficult.
Economics is an important subject.
News is spreading quickly.

❌ The news are good.
✅ The news is good.

20. Subject–Verb Agreement with Modal Verbs

After modal verbs such as:

can, could, may, might, shall, should, will, would, must

use the base form of the main verb.

He can speak English.
She can drive.
They can drive.
You should study.
He should study.

❌ He can speaks English.
✅ He can speak English.

Remember

Modal + Base Verb

21. Subject–Verb Agreement with “Do”, “Does” and “Did”

Present

Use does with he, she and it.

He does his work.
She does her homework.

Use do with I, you, we and they.

I do my work.
They do their work.

Past

Use did for all subjects.

I did my work.
She did her work.
They did their work.

Important

After do/does/did, use the base form of the main verb.

❌ Does she likes tea?
✅ Does she like tea?

❌ Did he went home?
✅ Did he go home?

22. Subject–Verb Agreement in Questions

The auxiliary verb usually carries the agreement.

Statement

She works here.

Question

Does she work here?

Not:

❌ Does she works here?

Another example:

They are ready.

Are they ready?

23. Common Mistakes Made by English Learners

Mistake 1

❌ He go to college every day.
✅ He goes to college every day.

Mistake 2

❌ She don’t like tea.
✅ She doesn’t like tea.

Mistake 3

❌ They doesn’t understand.
✅ They don’t understand.

❌ Everyone are happy.
✅ Everyone is happy.

Mistake 5

✅ My friends like cricket.

Mistake 6

24. Subject–Verb Agreement in Spoken English

In everyday conversation, we often use contractions, but the agreement rule remains the same.

Formal

She does not work here.

Natural conversation

She doesn’t work here.

Formal

They do not understand the problem.

Natural conversation

They don’t understand the problem.

The important point is:

Spoken English can be shorter and more natural, but the subject–verb relationship still matters.
