Understanding how to construct complex sentences is essential for mastering the English language. Complex sentences allow you to express more nuanced and detailed thoughts, making your communication more effective and sophisticated. At the heart of these complex sentences are conjunctions, which serve as the glue that holds different clauses together. In this article, we will delve into the world of conjunctions in complex sentences, exploring their types, functions, and providing examples to help you use them correctly.
What Are Complex Sentences?
Before diving into conjunctions, it’s important to understand what constitutes a complex sentence. A complex sentence is a sentence that contains at least one independent clause and one or more dependent clauses. An independent clause can stand alone as a sentence, while a dependent clause cannot and relies on the main clause to give it meaning.
For example:
– Independent clause: I went to the store.
– Dependent clause: Because I needed milk.
When combined, they form a complex sentence:
– I went to the store because I needed milk.
Types of Conjunctions
Conjunctions are words that connect clauses, phrases, or words. There are three main types of conjunctions: coordinating conjunctions, subordinating conjunctions, and correlative conjunctions. In the context of complex sentences, we focus primarily on subordinating conjunctions, though it’s useful to understand the other types as well.
Coordinating Conjunctions
Coordinating conjunctions connect words, phrases, or clauses that are of equal importance. They are often remembered by the acronym FANBOYS:
– For
– And
– Nor
– But
– Or
– Yet
– So
Example:
– I wanted to go for a walk, but it started to rain.
Subordinating Conjunctions
Subordinating conjunctions introduce dependent clauses and show the relationship between the dependent clause and the independent clause. These conjunctions are crucial in forming complex sentences because they add depth and detail to your statements.
Common subordinating conjunctions include:
– Because
– Although
– Since
– Unless
– While
– After
– Before
– If
Examples:
– I stayed home because it was raining.
– Although he was tired, he finished his homework.
Correlative Conjunctions
Correlative conjunctions work in pairs to join words or phrases that are equally important in a sentence. Some common pairs include:
– Either…or
– Neither…nor
– Both…and
– Not only…but also
Examples:
– Either you can come with us, or you can stay home.
– Not only did she win the race, but she also set a new record.
Subordinating Conjunctions in Detail
Since subordinating conjunctions are pivotal in forming complex sentences, let’s explore them in more detail.
Cause and Effect
Subordinating conjunctions that show cause and effect include because, since, and as.
Examples:
– I didn’t go to the party because I was feeling ill.
– Since she moved to the city, she has made many new friends.
In these examples, the dependent clause (because I was feeling ill, since she moved to the city) explains the reason for the action in the independent clause.
Contrast
Subordinating conjunctions that show contrast include although, though, even though, and whereas.
Examples:
– Although it was raining, we went for a hike.
– Even though he was late, he managed to catch the bus.
Here, the dependent clause (although it was raining, even though he was late) presents a contrast to the main action in the independent clause.
Condition
Subordinating conjunctions that show condition include if, unless, and provided that.
Examples:
– If you study hard, you will pass the exam.
– Unless it stops raining, we will cancel the picnic.
In these sentences, the dependent clause (if you study hard, unless it stops raining) sets a condition for the action in the independent clause.
Time
Subordinating conjunctions that indicate time include when, while, as soon as, before, and after.
Examples:
– When the sun sets, the sky turns orange.
– After she finished her work, she went for a walk.
In these examples, the dependent clause (when the sun sets, after she finished her work) specifies the timing of the action in the independent clause.
Combining Clauses with Subordinating Conjunctions
When combining independent and dependent clauses, the placement of the subordinating conjunction can change the emphasis of the sentence. Generally, the dependent clause can either come before or after the independent clause. If the dependent clause comes first, it is usually followed by a comma. If the independent clause comes first, a comma is typically not necessary.
Examples:
– Because I was tired, I went to bed early.
– I went to bed early because I was tired.
Both sentences are correct, but the first emphasizes the reason (because I was tired), while the second emphasizes the action (I went to bed early).
Common Mistakes and How to Avoid Them
When using subordinating conjunctions in complex sentences, it’s easy to make mistakes. Here are some common errors and tips on how to avoid them.
Fragmented Sentences
A common mistake is creating a sentence fragment by not including an independent clause with the dependent clause.
Incorrect:
– Because I was tired.
Correct:
– Because I was tired, I went to bed early.
Always make sure that your dependent clause is paired with an independent clause to form a complete sentence.
Comma Misuse
Another common error is incorrect comma placement. Remember, if the dependent clause comes first, it should be followed by a comma. If the independent clause comes first, a comma is usually not needed.
Incorrect:
– Because I was tired I went to bed early.
– I went to bed early, because I was tired.
Correct:
– Because I was tired, I went to bed early.
– I went to bed early because I was tired.
Confusing Conjunctions
Sometimes, learners confuse subordinating conjunctions with coordinating or correlative conjunctions. Make sure you understand the function of each type of conjunction to use them correctly.
Incorrect:
– I went to the store and I needed milk. (This should be a complex sentence with a subordinating conjunction.)
Correct:
– I went to the store because I needed milk.
Practice Makes Perfect
The best way to master the use of conjunctions in complex sentences is through practice. Here are some exercises to help you get started:
Exercise 1: Identify the Clauses
Identify the independent and dependent clauses in the following sentences. Then, name the subordinating conjunction used.
1. Although she was tired, she finished her homework.
2. I will go to the beach if the weather is nice.
3. Since he moved to the city, he has been very busy.
4. When the sun rises, the birds start singing.
Answers:
1. Independent clause: she finished her homework; Dependent clause: Although she was tired; Subordinating conjunction: Although
2. Independent clause: I will go to the beach; Dependent clause: if the weather is nice; Subordinating conjunction: if
3. Independent clause: he has been very busy; Dependent clause: Since he moved to the city; Subordinating conjunction: Since
4. Independent clause: the birds start singing; Dependent clause: When the sun rises; Subordinating conjunction: When
Exercise 2: Combine the Clauses
Combine the following pairs of clauses into complex sentences using an appropriate subordinating conjunction.
1. I didn’t go to the party. I was feeling ill.
2. She studied hard. She wanted to pass the exam.
3. He went for a walk. It was raining.
4. I will call you. I arrive home.
Possible answers:
1. I didn’t go to the party because I was feeling ill.
2. She studied hard because she wanted to pass the exam.
3. Although it was raining, he went for a walk.
4. I will call you when I arrive home.
Exercise 3: Correct the Mistakes
Correct the mistakes in the following sentences.
1. Unless it stops raining, we will cancel the picnic.
2. Because I was tired I went to bed early.
3. I went to bed early, because I was tired.
4. Since she moved to the city she has made many new friends.
Corrected sentences:
1. Unless it stops raining, we will cancel the picnic. (Correct as is)
2. Because I was tired, I went to bed early.
3. I went to bed early because I was tired.
4. Since she moved to the city, she has made many new friends.
Advanced Use of Conjunctions
As you become more comfortable with basic conjunctions, you can start exploring more advanced uses and variations.
Multiple Subordinating Conjunctions
Sometimes, you may need to use more than one subordinating conjunction in a complex sentence to express more intricate relationships between ideas.
Example:
– Although it was raining, we decided to go for a hike because we had planned it for weeks.
In this sentence, “although” introduces a contrast, and “because” introduces a reason, showing a complex relationship between the clauses.
Omitting Conjunctions
In some cases, you can omit conjunctions for stylistic reasons or to create a specific effect. This is more common in spoken English or informal writing.
Example:
– I was tired; I went to bed early.
Here, the semicolon replaces the conjunction, creating a more concise sentence while still connecting the ideas.
Using Conjunctions in Formal Writing
In formal writing, it’s important to use conjunctions appropriately to maintain clarity and coherence. Overusing conjunctions can make your writing appear cluttered, while underusing them can make it choppy.
Example of overuse:
– Because I was tired, and because I had a headache, and because I had a long day at work, I went to bed early.
Example of balanced use:
– Because I was tired and had a headache after a long day at work, I went to bed early.
