Conjunctions are words used to connect clauses, sentences, or phrases. They help join ideas together and create more complex, cohesive sentences. By linking words and groups of words, conjunctions help to show the relationship between different parts of a sentence, such as cause and effect, contrast, or addition. Common conjunctions include "and," "but," "or," and "because." There are three main types of conjunctions: coordinating, subordinating, and correlative, each serving a unique purpose in sentence structure.
What Are the Different Types of Conjunctions?
Conjunctions are essential elements in sentence structure, used to link words, phrases, or clauses to express complex ideas and relationships. There are three main types of conjunctions: coordinating conjunctions, subordinating conjunctions, and correlative conjunctions. Each type serves a specific purpose in connecting ideas within a sentence.
1. Coordinating Conjunctions
Definition Coordinating conjunctions connect words, phrases, or clauses that are of equal grammatical importance. These conjunctions help link elements that hold the same weight in a sentence, such as two independent clauses or two nouns.
Common Examples The most commonly used coordinating conjunctions are for, and, nor, but, or, yet, and so. A useful acronym to remember them is FANBOYS.
Purpose Coordinating conjunctions are used to join independent clauses, making the sentence smoother and more concise. For example, instead of writing "She likes pizza. She also likes pasta," you can say, "She likes pizza and pasta."
2. Subordinating Conjunctions
Definition Subordinating conjunctions connect an independent clause to a dependent (subordinate) clause. The dependent clause relies on the independent clause to complete its meaning, as it cannot stand alone as a complete sentence.
Common Examples Some of the most frequently used subordinating conjunctions are because, although, since, if, when, while, before, after, unless, and though.
Purpose Subordinating conjunctions are essential in forming complex sentences. They help provide more detail and depth by connecting a dependent clause to the main idea expressed in the independent clause. For example, "Although it was cold, we went for a swim" combines two related ideas in a single sentence, with the subordinating conjunction although adding important context.
3. Correlative Conjunctions
Definition Correlative conjunctions work in pairs to link elements that are equally important within a sentence. These conjunctions join words, phrases, or clauses, emphasizing a relationship between them.
Common Examples The most common correlative conjunction pairs are either/or, neither/nor, not only/but also, both/and, whether/or, and so/as.
Purpose Correlative conjunctions work to strengthen the connection between ideas and provide balance within a sentence. They often add emphasis or present multiple options in a more complex manner than simple coordinating conjunctions.
Differences Between the Types of Conjunctions
Coordinating Conjunctions Link elements of equal importance, typically joining two independent clauses or words within the same part of speech.
Subordinating Conjunctions Connect a dependent clause to an independent clause, often explaining time, cause, condition, or contrast.
Correlative Conjunctions Work in pairs to relate two equal elements within a sentence, providing balance and emphasis.
Coordinating conjunctions are used to connect words, phrases, or clauses that are of equal importance or grammatical structure within a sentence. These conjunctions help combine ideas smoothly, making writing and speech more fluid and concise. The seven coordinating conjunctions in English are for, and, nor, but, or, yet, and so, often remembered by the acronym FANBOYS.
Functions of Coordinating Conjunctions
Connecting Words Coordinating conjunctions link two or more individual words.
Example: "She likes apples and oranges."
In this case, and joins two nouns of equal importance.
Connecting Phrases They also join phrases that hold equal weight in a sentence.
Example: "We went to the store and bought some fruit."
Here, and connects two verb phrases.
Connecting Clauses Coordinating conjunctions are often used to join independent clauses (complete sentences), creating compound sentences.
Example: "I wanted to go for a walk, but it started raining."
But links two independent clauses that contrast each other.
Common Coordinating Conjunctions and Their Uses
For Explains a reason or cause (similar to "because").
Example "I went to bed early, for I was very tired."
And Adds or combines similar ideas.
Example "She is smart and hardworking."
Nor Presents a negative option or alternative, usually after another negative idea.
Example "He doesn't like pizza, nor does he enjoy pasta."
But Shows contrast or exception between two ideas.
Example "I like coffee, but I don't like tea."
Or Offers alternatives or choices.
Example "Would you prefer tea or coffee?"
Yet Indicates contrast, similar to but, but implies a surprising twist or unexpected result.
Example "He's 80 years old, yet he still runs marathons."
So Shows a cause-and-effect relationship.
Example "She studied hard, so she passed the exam."
Rules for Using Coordinating Conjunctions
Joining Independent Clauses When coordinating conjunctions connect two independent clauses, they are usually preceded by a comma.
Example "I wanted to play outside, but it was raining."
No Comma for Simple Lists When joining words or phrases, a comma is not needed unless it's part of a more complex list.
Example "We bought apples and bananas." (no comma)
Avoid Starting Sentences with FANBOYS (in formal writing) Although it's becoming more acceptable in casual writing to begin sentences with a coordinating conjunction, it is generally avoided in formal writing.
What Are Correlative Conjunctions and How Are They Used?
Correlative conjunctions are pairs of conjunctions that work together to join equal grammatical elements in a sentence, such as words, phrases, or clauses. They always come in pairs and help emphasize the connection between the two parts. Correlative conjunctions ensure that the two elements, being joined, are treated equally within the sentence structure.
Common Correlative Conjunction Pairs
Either/Or Used to present two positive or alternative options.
Example "Either you study hard, or you will fail the test."
Neither/Nor Used to connect two negative alternatives.
Example "Neither John nor Mary could attend the meeting."
Not Only/But Also Used to add emphasis by connecting two related pieces of information, showing that both are true or important.
Example "She is not only a talented artist but also a skilled musician."
Both/And Used to connect two positive ideas or elements, showing that both are true or applicable.
Example "Both the teacher and the students enjoyed the project."
Whether/Or Used to express uncertainty between two choices.
Example "I'm not sure whether to take the train or drive to work."
As/As Used to show equality or comparison between two things.
Example "She is as tall as her brother."
How Correlative Conjunctions Are Used
Connecting Equal Elements Correlative conjunctions always link two elements that are grammatically similar, such as two nouns, adjectives, phrases, or clauses.
Example: "You can choose either the red shirt or the blue one."
Both the red shirt and the blue one are noun phrases of equal weight.
Parallel Structure One of the most important rules for using correlative conjunctions is maintaining parallel structure, meaning that the grammatical form of the words or phrases connected by the conjunctions must be the same.
Correct Example: "Not only is she smart, but also she is hardworking."
Incorrect Example: "Not only is she smart, but also works hard."
Emphasis Correlative conjunctions often emphasize the relationship between two ideas or stress that both parts of the sentence are equally important.
Example: "Both her intelligence and her dedication helped her succeed."
Here, the conjunction pair highlights that both qualities contributed to the success.
Avoiding Double Negatives When using neither/nor, be cautious to avoid double negatives, which can confuse the meaning.
Correct Example "Neither the rain nor the wind stopped them."
Incorrect Example "Neither the rain nor the wind didn't stop them." (This is a double negative.)
Common Mistakes to Avoid
Lack of Parallelism Correlative conjunctions must join elements that are grammatically similar. Mixing different grammatical forms disrupts the flow of the sentence and can lead to confusion.
Incorrect "Either you can take the bus or driving your car."
Correct "Either you can take the bus or you can drive your car."
Using the Wrong Pair Correlative conjunctions must be used as pairs. Mixing parts of different conjunction pairs is grammatically incorrect.
Subordinating conjunctions connect an independent clause with a dependent (or subordinate) clause, showing a relationship between the two. The dependent clause cannot stand alone as a complete sentence and depends on the independent clause for meaning. Subordinating conjunctions often introduce ideas related to time, reason, condition, contrast, or cause and effect.
Role of Subordinating Conjunctions
Subordinating conjunctions serve as a bridge between two ideas, making one idea subordinate (less important or dependent) to the main idea. This helps create complex sentences where the relationship between the ideas is clearer and more nuanced.
For example
"She went home because she was feeling sick."
Here, "because" introduces a reason (she was feeling sick) that explains the action in the main clause (she went home).
Common Subordinating Conjunctions and Their Uses
Time Shows when something happens in relation to something else.
The action of calling happens after the speaker arrives, linked by the conjunction "after."
Reason or Cause Explains why something happens.
Examples Because, since, as.
Example Sentence "She didn't go to school because she was sick."
"Because" introduces the reason for not going to school.
Condition Establishes conditions for the action in the main clause.
Examples If, unless, provided that, as long as.
Example Sentence "I'll go if you go."
"If" introduces the condition under which the speaker will go.
Contrast or Opposition Highlights a difference or contradiction between two ideas.
Examples Although, though, whereas, even though, while.
Example Sentence "Although it was raining, they continued playing."
"Although" introduces a contrasting idea to the action of playing.
Purpose or Result Explains the purpose or result of an action.
Examples So that, in order that.
Example Sentence "She studied hard so that she could pass the exam."
"So that" introduces the result of studying hard.
Comparison Shows how one thing compares to another.
Examples Than, as…as.
Example Sentence "She is taller than her brother."
"Than" introduces the comparison between her and her brother.
Structure of Sentences with Subordinating Conjunctions
Subordinating conjunctions can be placed at the beginning or middle of a sentence, depending on how you want to structure the sentence.
Subordinating Conjunction at the Beginning When the subordinating conjunction starts the sentence, a comma is typically placed after the dependent clause.
Example "Although it was late, they kept working."
The dependent clause, "Although it was late," is followed by a comma before the independent clause, "they kept working."
Subordinating Conjunction in the Middle When the subordinating conjunction appears between the independent and dependent clause, no comma is needed.
Example "They kept working although it was late."
In this case, the dependent clause follows the independent clause without a comma.
The Importance of Subordinating Conjunctions
Clarify Relationships Subordinating conjunctions clearly indicate the relationship between ideas, such as time, cause, or contrast. This makes sentences more informative and easier to understand.
Example "She ran faster because she wanted to win."
The subordinating conjunction because shows the cause of her running faster.
Add Complexity to Writing By using subordinating conjunctions, writers can form complex sentences, which provide more detail and help avoid choppy, simple sentences.
Simple Sentence "I was late. The bus was slow."
Complex Sentence "I was late because the bus was slow."
The complex sentence offers more explanation and connects the two ideas more smoothly.
Improve Flow and Coherence Subordinating conjunctions help maintain logical flow and coherence in writing by showing how ideas are related.
Example "When the bell rings, you may leave."
The sentence explains the timing of the action, helping the reader follow the logic of the sequence.
What Are the Key Rules for Using Conjunctions Correctly?
Conjunctions are essential tools in sentence construction, helping link words, phrases, or clauses to express ideas clearly and logically. However, using them correctly is important to avoid grammatical errors and ensure sentences flow smoothly. Below are some key rules to follow when using conjunctions in writing.
1. Maintain Parallel Structure
When conjunctions join two or more elements, the grammatical structure of those elements should be the same. This is known as parallelism.
Correct Example "She enjoys reading, writing, and swimming."
Incorrect Example "She enjoys reading, writing, and to swim."
In the incorrect example, "to swim" breaks the parallel structure because it's an infinitive, while the other items are gerunds.
2. Use a Comma Before a Coordinating Conjunction in Compound Sentences
When a coordinating conjunction (e.g., and, but, or, so) connects two independent clauses, a comma is usually placed before the conjunction.
Correct Example "I wanted to go for a walk, but it started raining."
Incorrect Example "I wanted to go for a walk but it started raining."
However, if the coordinating conjunction is connecting words or phrases rather than full clauses, no comma is needed.
Correct Example "She likes apples and oranges."
3. Avoid Starting Sentences with Coordinating Conjunctions in Formal Writing
Although it is increasingly acceptable in casual writing to start a sentence with a coordinating conjunction (e.g., and, but, or), it is generally discouraged in formal writing. If used, ensure it doesn't result in a sentence fragment.
Casual Example "But I didn't have time to finish."
Formal Alternative "However, I didn't have time to finish."
4. Use Subordinating Conjunctions to Create Complex Sentences
Subordinating conjunctions (e.g., because, although, since, if) are used to connect a dependent clause to an independent clause, forming a complex sentence. When a sentence begins with a subordinating conjunction, use a comma after the dependent clause.
Correct Example "Because she was late, she missed the meeting."
Correct Example "She missed the meeting because she was late."
(Note: No comma is needed when the subordinating conjunction is in the middle of the sentence.)
5. Place Correlative Conjunctions Correctly
Correlative conjunctions (e.g., either/or, neither/nor, both/and) come in pairs and must be placed properly to join equivalent grammatical elements.
Correct Example "Either you leave now or you miss the bus."
Incorrect Example "Either you leave now and you miss the bus."
Ensure the elements connected by correlative conjunctions are balanced and parallel.
6. Avoid Overuse of Conjunctions
Overusing conjunctions can make sentences unnecessarily long or complex. Instead of repeatedly using conjunctions to link ideas, consider breaking long sentences into shorter, clearer ones.
Overuse Example "I wanted to go out but it was raining and I didn't have an umbrella so I stayed inside."
Revised Example "I wanted to go out, but it was raining. Since I didn't have an umbrella, I stayed inside."
7. Use Appropriate Conjunctions for the Context
Different conjunctions express different relationships between ideas, such as addition (and), contrast (but), cause (because), or alternatives (or). Choose conjunctions that accurately convey the relationship between the connected ideas.
Correct Example "She was tired, but she kept working."
(But correctly shows contrast between being tired and continuing to work.)
Incorrect Example "She was tired, so she kept working."
(So suggests a cause-effect relationship, which doesn't fit this context.)
8. Be Mindful of Double Negatives with "Neither/Nor"
When using neither/nor, avoid double negatives. A double negative creates confusion and can make the sentence difficult to understand.
Correct Example "Neither the students nor the teacher was happy with the results."
Incorrect Example "Neither the students nor the teacher wasn't happy with the results."
9. Keep Conjunctions Consistent with Sentence Tone and Formality
In formal writing, certain conjunctions may be more appropriate than others. For example, therefore, however, and thus are often used in place of simpler conjunctions like and or but in more formal contexts.
Formal Example "She studied diligently; therefore, she passed the exam."
Informal Example "She studied diligently, so she passed the exam."
10. Understand the Difference Between Conjunctions and Connectives
Conjunctions link clauses within a sentence, while connectives (like however, nevertheless, or furthermore) typically connect ideas between sentences or paragraphs. Use conjunctions within a sentence and connectives to guide transitions between larger sections of text.
Conjunction Example "I like coffee, but I don't drink it often."
Connective Example "I enjoy coffee. However, I don't drink it often."
How Are Conjunctions Used in Complex Sentences?
Conjunctions play a crucial role in forming complex sentences, which consist of one independent clause and at least one dependent (subordinate) clause. The use of subordinating conjunctions links these clauses together, showing the relationship between the main idea and the subordinate idea. Complex sentences add depth, detail, and clarity to writing by combining related thoughts in a single sentence.
1. Understanding Independent and Dependent Clauses
Independent Clause A group of words that expresses a complete thought and can stand alone as a sentence.
Example "She went to the park."
Dependent (Subordinate) Clause A group of words that cannot stand alone as a sentence because it relies on an independent clause to complete its meaning.
Example "Although she was tired."
In a complex sentence, the dependent clause adds additional information, such as reasons, time, conditions, or contrasts, to the independent clause.
Example of a Complex Sentence "Although she was tired, she went to the park."
In this sentence, "Although she was tired" is the dependent clause, and "she went to the park" is the independent clause. The conjunction although connects the two, introducing a contrast.
2. Subordinating Conjunctions in Complex Sentences
Subordinating conjunctions introduce the dependent clause and indicate how it relates to the independent clause. They can express time, reason, condition, contrast, or cause and effect.
Common Subordinating Conjunctions
Timewhen, after, before, while, as soon as, until
Example: "We will leave when the rain stops."
Reasonbecause, since, as
Example "She stayed home because she wasn't feeling well."
Conditionif, unless, provided that
Example "I'll help you if you need me."
Contrastalthough, though, even though
Example "They finished the race even though they were exhausted."
Cause and Effectso that, in order that
Example "He studied hard so that he could pass the exam."
3. Sentence Structure with Complex Sentences
Subordinating conjunctions can appear at the beginning or in the middle of a complex sentence. The placement of the conjunction affects whether or not a comma is needed.
a. Dependent Clause First (Subordinating conjunction at the beginning)
When the dependent clause comes first, a comma is placed after the clause to separate it from the independent clause.
Example "Because it was raining, we stayed inside."
b. Independent Clause First (Subordinating conjunction in the middle)
When the independent clause comes first, no comma is needed before the dependent clause.
Example "We stayed inside because it was raining."
4. Purpose of Using Conjunctions in Complex Sentences
Add Depth and Detail Complex sentences allow writers to include more information in a single sentence, explaining reasons, conditions, or timing.
Clarify Relationships Subordinating conjunctions make the relationship between ideas clearer, showing how one clause is dependent on or connected to another.
Example "Although it was late, they kept working."
Create Logical Flow By using subordinating conjunctions, complex sentences help connect ideas in a logical sequence, improving the overall flow of the writing.
Example "She didn't join us because she had an important meeting."
5. Examples of Complex Sentences Using Subordinating Conjunctions
Time "After she finished her homework, she went out to play."
The dependent clause "After she finished her homework" explains the time when the independent action "she went out to play" occurred.
Reason "We couldn't attend the event because the tickets were sold out."
The conjunction because links the reason for not attending the event with the main action.
Condition "You can borrow my bike if you promise to take care of it."
The dependent clause "if you promise to take care of it" sets a condition for the action in the independent clause.
Contrast "He continued working even though he was tired."
The conjunction even though introduces a contrast between being tired and continuing to work.
6. Common Mistakes to Avoid in Complex Sentences
Misplacing the Comma A common mistake is misusing commas in complex sentences. Remember, a comma is only needed if the dependent clause comes first.
Incorrect "We stayed inside, because it was raining."
Correct "We stayed inside because it was raining."
Dependent Clause Fragment Ensure the dependent clause is paired with an independent clause. A dependent clause alone cannot be a complete sentence.
Incorrect "Although she was late."
Correct "Although she was late, she didn't miss the bus."
Conjunctions are vital for connecting ideas smoothly, but improper use can lead to confusion, grammatical errors, or awkward sentence construction. Below are some common errors in using conjunctions and tips on how to avoid them.
1. Run-On Sentences
A run-on sentence occurs when two independent clauses are connected without the proper punctuation or conjunction. This mistake often happens when writers try to join two complete sentences with just a coordinating conjunction or no conjunction at all.
Incorrect "She loves reading she goes to the library often."
Correct "She loves reading, and she goes to the library often."
Correct (with a period) "She loves reading. She goes to the library often."
2. Comma Splice
A comma splice happens when two independent clauses are incorrectly joined with a comma but without a coordinating conjunction.
Incorrect "I was tired, I went to bed early."
Correct "I was tired, so I went to bed early."
Correct (with a semicolon) "I was tired; I went to bed early."
3. Overuse of Conjunctions
Overusing conjunctions, especially in long sentences, can make writing clunky or difficult to follow. Excessive conjunctions can create overly complex or confusing sentence structures.
Incorrect "He went to the store, and he bought some milk, and then he went home, and he made dinner."
Correct "He went to the store, bought some milk, and then went home to make dinner."
4. Misplacing Commas with Coordinating Conjunctions
When coordinating conjunctions join two independent clauses, a comma should be placed before the conjunction. However, many writers either omit the comma or place it incorrectly.
Incorrect "She studied hard but didn't pass the exam."
Correct "She studied hard, but she didn't pass the exam."
If the conjunction connects two words or phrases (not independent clauses), no comma is needed.
Correct "I like apples and oranges."
5. Incorrect Use of Subordinating Conjunctions
Subordinating conjunctions, like because, although, and since, are used to connect a dependent clause to an independent clause. A common error is failing to properly connect or punctuate these clauses.
Incorrect "Although he was late. He still joined the meeting."
This creates a fragment because the dependent clause is not linked to an independent clause.
Correct "Although he was late, he still joined the meeting."
6. Confusing Correlative Conjunctions
Correlative conjunctions (e.g., either/or, neither/nor, not only/but also) must be used in pairs and should connect grammatically parallel elements. A frequent error is breaking this parallel structure.
Incorrect "She is either going to the mall or stay at home."
Correct "She is either going to the mall or staying at home."
7. Starting Sentences with Coordinating Conjunctions in Formal Writing
In casual writing, it is acceptable to begin a sentence with a coordinating conjunction like and or but. However, in formal writing, starting sentences with coordinating conjunctions is usually discouraged.
Informal "But I didn't know how to respond."
Formal "However, I didn't know how to respond."
8. Using "But" and "However" Incorrectly
While both but and however express contrast, they are used differently. But is a coordinating conjunction and is used within a sentence, while however is a connective and is typically used at the beginning of a new sentence or clause.
Incorrect "She is tired, however she will finish the work."
Correct "She is tired, but she will finish the work."
Correct "She is tired. However, she will finish the work."
9. Double Negatives with "Neither/Nor"
When using the correlative conjunction neither/nor, avoid double negatives, which can make the sentence unclear or grammatically incorrect.
Incorrect "She didn't want neither tea nor coffee."
Correct "She wanted neither tea nor coffee."
10. Omitting Conjunctions in Compound Sentences
In compound sentences, omitting a necessary conjunction between clauses can result in awkward sentence structure or confusion.
Incorrect "She likes pizza, he likes pasta."
Correct "She likes pizza, and he likes pasta."
What Is the Difference Between Conjunctions and Connectives?
Conjunctions and connectives both serve to link ideas in writing and speech, but they function in different ways and are used in distinct contexts. Understanding the difference between the two helps in constructing clear and coherent sentences, especially when connecting complex ideas.
1. Conjunctions
Conjunctions are specific words that join words, phrases, or clauses within the same sentence. They directly link elements together to show a relationship between them, whether it be addition, contrast, condition, or cause and effect.
Types of Conjunctions
Coordinating Conjunctions Join elements of equal importance (e.g., and, but, or).
Example "She wanted to go to the park, but it started raining."
Subordinating Conjunctions Join an independent clause to a dependent clause (e.g., because, although, if).
Example "She stayed home because it was raining."
Correlative Conjunctions Work in pairs to join equal elements (e.g., either/or, neither/nor).
Example "You can either stay home or come with us."
Key Feature Conjunctions typically work within a sentence to link clauses or ideas, ensuring smooth transitions between them.
2. Connectives
Connectives are words or phrases that connect ideas between sentences or paragraphs, helping to guide readers through the flow of information. They serve a broader purpose than conjunctions, often structuring and organizing the overall text. Connectives may indicate time, contrast, cause and effect, sequence, or additional information, but they typically function at a higher level than conjunctions.
Examples of Connectives
Addition Moreover, furthermore, in addition
Example "The weather was perfect. Furthermore, we had a great time at the beach."
Contrast However, on the other hand, nevertheless
Example "He wanted to go outside. However, it started to rain."
Cause and Effect Therefore, as a result, consequently
Example "She missed the bus. As a result, she was late for the meeting."
Time Meanwhile, afterward, before that
Example "We finished our work. Afterward, we went out for dinner."
Key Feature Connectives link ideas between sentences or paragraphs, providing transitions that help clarify the relationship between broader ideas or events.

4. When to Use Conjunctions and Connectives
Conjunctions Use conjunctions when linking words, phrases, or clauses in the same sentence. They are essential for building compound and complex sentences.
Example "We went to the park, but it started raining."
Connectives Use connectives when connecting ideas between sentences, helping to maintain the flow of information or to provide transitions between paragraphs or sections.
Example "The park was beautiful. Moreover, the weather was perfect."
We learned about different types of conjunctions; coordinating, subordinating, and correlative, and how they are used in various sentence structures, such as simple, compound, and complex sentences. We also looked at how conjunctions differ between languages, showing how grammar changes across cultures. Additionally, we discussed common mistakes in using conjunctions and explained the difference between conjunctions and connectives.
This lesson improves the understanding of how to form sentences and makes their writing clearer and more connected. Learning about conjunctions helps create sentences that flow smoothly, making communication easier to follow. It also helps one understand how different languages use conjunctions, which is useful for those learning new languages.
