By the end of this lesson, you should be able to:
Instead of writing two separate sentences such as “I was tired. I finished my homework,” you can connect the ideas: “I was tired, but I finished my homework.”
When we speak or write English, we often need to connect one idea with another. We may want to add information, show a difference, give a reason, or explain a choice.
Conjunctions are words that help us make these connections. They allow us to combine ideas without making our communication unnecessarily repetitive.
Without a conjunction: I like apples. I like bananas.
With a conjunction: I like apples and bananas.
The word and connects two items in one sentence.
Without a conjunction: It was raining. We went outside.
With a conjunction: It was raining, but we went outside.
The word but connects two ideas that contrast.
I stayed home because I was feeling unwell.
The word because introduces the reason for staying home.
She bought bread and milk.
He is young, but he is responsible.
Would you like tea or coffee?
We left early because it was late.
It was cold, so I wore a jacket.
Although it was difficult, she tried.
Conjunctions help you express relationships between ideas. Without them, your sentences may sound repetitive, disconnected, or unclear. Using them correctly makes everyday communication more natural.
Connect thoughts naturally while talking with friends, teachers, colleagues, and other people.
Example: I wanted to call you, but I was busy.
Join related ideas and make paragraphs easier to follow.
Example: She studied hard, so she passed the exam.
Give explanations and help listeners understand why something happened.
Example: He stayed inside because it was raining.
Express choices, contrasts, conditions, and results more clearly.
Example: You can walk or take the bus.
| Situation | Example Sentence | Purpose |
|---|---|---|
| At home | I cleaned the room and washed the dishes. | Addition |
| At school | I studied hard, but the test was difficult. | Contrast |
| At work | We finished early because everyone helped. | Reason |
| Shopping | You can pay by cash or card. | Choice |
| Travelling | The train was delayed, so we waited. | Result |
A conjunction is a word that connects words, phrases, or clauses. It helps show how different parts of a sentence are related.
Conjunctions can express addition, contrast, choice, reason, result, condition, time, and other relationships between ideas.
I bought apples and oranges.
The conjunction and connects two nouns: apples and oranges.
She likes reading and writing stories.
The conjunction and connects two activities: reading and writing stories.
I stayed home because I felt sick.
The word because connects the main clause “I stayed home” with the dependent clause “I felt sick.”
| Sentence | What Is Connected? | Conjunction |
|---|---|---|
| Riya and Aman are friends. | Two nouns | and |
| He is tired but happy. | Two adjectives | but |
| You can walk or run. | Two verbs | or |
| We left because it was late. | Two clauses | because |
English conjunctions are commonly grouped into three main categories: coordinating, subordinating, and correlative conjunctions. Each category connects sentence elements in a different way.
| Type | What It Connects | Common Examples | Example Sentence |
|---|---|---|---|
| Coordinating | Words, phrases, or elements of equal grammatical importance | and, but, or, so | I was tired, but I continued. |
| Subordinating | A dependent clause to a main clause | because, although, if, when | I rested because I was tired. |
| Correlative | Paired elements in a sentence | either…or, neither…nor, both…and | Both Riya and Aman came. |
She bought a notebook and a pen.
Use it to add related information.
The bag is small, but it is useful.
Use it to connect contrasting ideas.
Would you like juice or water?
Use it to present alternatives.
She smiled because she was happy.
Use it to explain why something happens.
It was raining, so we stayed inside.
Use it to show a consequence or result.
Although it was cold, we went outside.
Use it to introduce an unexpected contrast.
Because: I took an umbrella because it was raining.
So: It was raining, so I took an umbrella.
Both sentences express a cause-and-result relationship, but they present the information in a different order.
Conjunctions can join individual words, groups of words, or clauses. The conjunction you choose depends on the relationship you want to express.
Noun + conjunction + noun
Example: I like tea and coffee.
The conjunction connects two nouns that have the same role in the sentence.
Phrase + conjunction + phrase
Example: She enjoys reading books and watching films.
The conjunction connects two activities expressed as phrases.
Independent clause + , + conjunction + independent clause
Example: I wanted to go outside, but it was raining.
Both clauses can stand alone as complete sentences. A comma is normally used before a coordinating conjunction joining two independent clauses.
Main clause + subordinating conjunction + dependent clause
Example: We cancelled the picnic because it was raining.
The clause beginning with “because” explains the reason and depends on the main clause to complete the thought.
Subordinating conjunction + dependent clause + , + main clause
Example: Although I was tired, I finished my work.
When the dependent clause comes first, a comma is generally used to separate it from the main clause.
Either + option A + or + option B
Example: You can either walk or take the bus.
Correlative conjunctions work in pairs to connect balanced elements.
Understanding the three main types will help you choose the correct conjunction when speaking and writing.
Coordinating conjunctions connect words, phrases, or clauses that have equal grammatical importance.
For, And, Nor, But, Or, Yet, So
These are often remembered using the acronym FANBOYS.
| Conjunction | Common Function | Example |
|---|---|---|
| For | Introduces a reason; often more formal | We went inside, for it was getting cold. |
| And | Addition | She sings and dances. |
| Nor | Adds a negative alternative | He did not call, nor did he send a message. |
| But | Contrast | I was tired, but I kept working. |
| Or | Choice or alternative | You can stay or leave. |
| Yet | Unexpected contrast | The task was difficult, yet she succeeded. |
| So | Result or consequence | I was hungry, so I made a sandwich. |
Subordinating conjunctions introduce dependent clauses and show how those clauses relate to a main clause.
| Conjunction | Relationship | Example |
|---|---|---|
| Because | Reason | I stayed home because I was sick. |
| Although | Contrast | Although it was late, we continued. |
| If | Condition | If you practise, you will improve. |
| When | Time | Call me when you arrive. |
| While | Time or contrast | She listened while I explained. |
| Before | Earlier time | Wash your hands before you eat. |
| After | Later time | We went home after the film ended. |
| Unless | Negative condition | You will not succeed unless you try. |
| Since | Reason or starting time | Since you are here, please help us. |
| Until | Time limit | Wait here until I return. |
Correlative conjunctions are pairs of words that work together to connect balanced sentence elements.
| Pair | Purpose | Example |
|---|---|---|
| Both…and | Includes two things | Both Ravi and Neha are helpful. |
| Either…or | Offers alternatives | You can either read or listen. |
| Neither…nor | Rejects both alternatives | Neither the manager nor the assistant was available. |
| Not only…but also | Adds emphasis to two points | She is not only kind but also generous. |
| Whether…or | Expresses alternatives or possibilities | I do not know whether he will call or write. |
Coordinating: connects elements of equal importance.
Subordinating: introduces a dependent clause.
Correlative: uses a pair of connecting words.
Follow these practical rules to connect ideas clearly and avoid common grammar errors.
Use and to connect related words, phrases, or clauses.
Correct: I bought a book and a notebook.
Correct: She opened the door and walked inside.
Use but when the connected ideas differ or contrast with each other.
Correct: The road was long, but we continued walking.
Incorrect: The road was long, and we continued walking.
The second sentence is not necessarily grammatically wrong, but but more clearly expresses the intended contrast.
Use or when offering alternatives or possibilities.
Correct: Would you like rice or bread?
Correct: Hurry up, or you may miss the bus.
A clause beginning with because explains why something happens.
Correct: She went to bed early because she was tired.
You can also put the because-clause first: “Because she was tired, she went to bed early.”
When the dependent clause comes first, use a comma before the main clause.
Use so to show the result or consequence of something.
Correct: I missed the bus, so I walked to school.
Compare: “I walked to school because I missed the bus” emphasizes the reason, while “I missed the bus, so I walked to school” emphasizes the result.
When a coordinating conjunction joins two independent clauses, a comma is normally placed before the conjunction.
Correct: I called her, but she did not answer.
A comma is not usually needed when the conjunction joins only two words or short phrases.
Correct: I called Ravi and Neha.
When a sentence begins with a dependent clause introduced by a subordinating conjunction, place a comma after that clause.
Correct: If you need help, call me.
Correct: Although it was raining, we went outside.
With pairs such as both…and and either…or, connect elements that have parallel grammatical structures.
Correct: She likes both singing and dancing.
Less balanced: She likes both singing and to dance.
The first sentence uses two -ing forms, making the structure parallel and natural.
In standard English, do not normally use because and so together to connect the same cause and result in one clause structure.
Incorrect: Because it was raining, so we stayed home.
Correct: Because it was raining, we stayed home.
Correct: It was raining, so we stayed home.
Do not normally use although and but together to express the same contrast in one sentence.
Incorrect: Although he was tired, but he continued.
Correct: Although he was tired, he continued.
Correct: He was tired, but he continued.
Different conjunctions express different relationships. Choose one that matches your intended meaning.
Addition: She is friendly and helpful.
Contrast: She is friendly, but she is shy.
Reason: She stayed home because she was ill.
Condition: If it rains, we will stay inside.
Many English learners understand conjunctions but sometimes use them incorrectly in sentences. Review these common mistakes and learn how to correct them.
Incorrect: Because I was hungry, so I ate a sandwich.
Correct: Because I was hungry, I ate a sandwich.
Also correct: I was hungry, so I ate a sandwich.
Use because to introduce a reason or so to show a result. Avoid using both together for the same cause-and-result connection.
Incorrect: Although she was tired, but she continued working.
Correct: Although she was tired, she continued working.
Also correct: She was tired, but she continued working.
Both although and but can express contrast, so normally choose one construction rather than combining both in this way.
Incorrect for the intended meaning: I was tired, because I went to bed early.
Better: I was tired, so I went to bed early.
Use so when you want to show that going to bed early was the result of being tired.
Incorrect in standard punctuation: I wanted to call her but she was busy.
Correct: I wanted to call her, but she was busy.
Use a comma before a coordinating conjunction when it joins two independent clauses. A comma is not normally needed when it joins only words or short phrases.
Less balanced: He likes both swimming and to run.
Better: He likes both swimming and running.
Keep the connected elements grammatically parallel. In the improved sentence, both activities use the -ing form.
Incomplete pair: You can either walk, take the bus.
Correct: You can either walk or take the bus.
Use both parts of a correlative pair when the sentence requires them. Here, either works with or to present two alternatives.
Addition: I need a pen and a notebook.
Choice: You can use a pen or a pencil.
And generally adds information, while or presents alternatives. Choose according to the meaning you intend.
Incorrect in standard punctuation: If you are free call me.
Correct: If you are free, call me.
When a dependent clause beginning with if, although, when, or another subordinating conjunction comes first, use a comma before the main clause.
Incorrect in standard English: I don’t like neither tea nor coffee.
Correct: I like neither tea nor coffee.
Also correct: I don’t like either tea or coffee.
In standard English, neither already expresses a negative meaning. Avoid adding another negative in this construction.
Meaning: You will not pass unless you study.
Equivalent: If you do not study, you will not pass.
Unless means “except if” and often expresses a negative condition. Make sure the condition matches the meaning you want.
Use these simple memory techniques to remember common conjunctions and choose the right one when building sentences.
Think of and as a word that adds another person, thing, or idea.
Example: I bought bread and butter.
Think of but when two ideas contrast with each other.
Example: The room is small, but comfortable.
Think of or when someone has to choose between alternatives.
Example: Would you like tea or coffee?
Ask “Why?” If the conjunction introduces the answer, because may be appropriate.
Example: I rested because I was tired.
Think of so as showing what happened as a consequence.
Example: I was tired, so I rested.
Use although when the second idea contrasts with what you might expect.
Example: Although it was cold, we went swimming.
F — For
A — And
N — Nor
B — But
O — Or
Y — Yet
S — So
The word FANBOYS helps you remember these seven coordinating conjunctions.
| Type | Memory Hint | Examples |
|---|---|---|
| Coordinating | Connects equal elements | and, but, or, so |
| Subordinating | Introduces a dependent clause | because, if, although, when |
| Correlative | Works in pairs | either…or, both…and |

📝 Take the Conjunctions QuizConjunctions are connecting words that help us express relationships between words, phrases, and clauses. They make speaking and writing clearer by showing how ideas relate to one another.
Conjunctions connect sentence elements and express relationships such as addition, contrast, reason, result, time, and condition.
Coordinating conjunctions connect elements of equal importance. Subordinating conjunctions introduce dependent clauses. Correlative conjunctions work in pairs.
Select a conjunction that matches your meaning, keep paired structures balanced, and use punctuation appropriately.
| Conjunction | Purpose | Example |
|---|---|---|
| and | Addition | I read and write every day. |
| but | Contrast | I was tired, but I continued. |
| or | Choice | Take a taxi or a bus. |
| because | Reason | I rested because I was tired. |
| so | Result | I was tired, so I rested. |
| although | Contrast | Although it was late, we continued. |
| if | Condition | If you practise, you will improve. |
Do not memorise conjunctions only by their spelling. Practise using them in meaningful sentences so you can connect your ideas naturally in conversations, messages, schoolwork, and professional writing.

Find simple answers to common questions about conjunctions, their types, and how to use them correctly in everyday English.
A conjunction is a word that connects words, phrases, or clauses. Examples include and, but, or, because, and although. For example: “I like tea and coffee.”
The three main types are coordinating, subordinating, and correlative conjunctions. Coordinating conjunctions connect elements of equal grammatical importance, subordinating conjunctions introduce dependent clauses, and correlative conjunctions work in pairs.
And adds information, but expresses contrast, and or presents choices or alternatives. For example: “I bought bread and milk,” “I was tired, but I continued,” and “Would you like tea or coffee?”
Because introduces a reason, while so introduces a result. For example: “I stayed home because I was sick” and “I was sick, so I stayed home.”
FANBOYS is a memory aid for seven coordinating conjunctions: For, And, Nor, But, Or, Yet, and So.
Correlative conjunctions are pairs of words that work together to connect balanced elements. Examples include both…and, either…or, neither…nor, and not only…but also.
Yes. For example: “Because it was raining, we stayed inside.” Use a comma after the introductory dependent clause.
Normally, use a comma before a coordinating conjunction when it joins two independent clauses. For example: “I wanted to leave, but my friend stayed.” A comma is generally unnecessary when the conjunction joins only words or short phrases.
Both can express contrast, but they are used in different sentence structures. Say “Although it was cold, we went outside” or “It was cold, but we went outside.”
Practise connecting short sentences, read English regularly, and learn conjunctions through complete examples. Pay attention to whether you are adding information, showing contrast, giving a reason, expressing a result, or introducing a condition.
Review this lesson whenever you need help using conjunctions. Revise the three main types, common conjunctions, sentence structures, punctuation rules, and examples to strengthen your grammar skills.
