Simple and Complex Sentences – Introduction
There are three types of sentences in English: simple, compound, and complex sentences. In this article we will focus on what a simple sentence is and what a compound sentence is.
Simple sentence – Definition
What is a simple sentence in English? A simple sentence is a sentence that has only one independent clause. An independent clause is a group of words that has a subject and a verb.
Let’s have a look at this example of a simple sentence:
| Subject | Verb | Object |
|---|---|---|
| Sam | walked | to the park. |
As you can see, this sentence has a simple sentence structure. In this simple sentence example, there is only one independent clause. It has a subject (Sam) and a verb (walked). Now you know how to write a simple sentence! It’s time to find out what makes a compound sentence.
Compound Sentence – Definition
What is a compound sentence? A compound sentence structure is different from the one of a simple sentence. How? A compound sentence contains two or more independent clauses. Here is a compound sentence example:
| Independent clause 1 | Independent clause 2 |
|---|---|
| Sam walked to the park, | but his sister stayed at home. |
In this sentence, there are two independent clauses. The first independent clause has a subject (Sam) and a verb (walked), and the second one also has a subject (sister) and a verb (stayed).
| Subject | Verb | Object | Coordinating Conjunction |
Subject | Verb | Object |
|---|---|---|---|---|---|---|
| Sam | walked | to the park, | but | his sister | stayed | at home. |
Now you know the difference between simple sentences and compound sentences. But how to make a compound sentence? There are three compound sentence types in English, and the most common is a compound sentence with a conjunction. Let’s find out what it is!
Compound Sentences with Coordinating Conjunctions
A coordinating conjunction is a word that joins two or more sentences together. Coordinating conjunctions are:
| Initial letter | Coordinating conjunction |
|---|---|
| F | for |
| A | and |
| N | nor |
| B | but |
| O | or |
| Y | yet |
| S | so |
Have a look at the first letter of each conjunction. What word do the first letters make? Fanboys! You can use the word FANBOYS to remember all the compound sentence conjunctions.
Coordinating Conjunctions – Examples
Now, let’s have a look at examples of changing simple sentences to compound sentences with FANBOYS. There are two simple sentences, each of which has one independent clause:
| Sentence 1 | Sentence 2 |
|---|---|
| I got a flat tire. | I called a tow truck. |
Which coordinating conjunction can we use to combine these two simple sentences into a compound sentence? Be careful, as not all the conjunctions will make sense. In this case, we will choose so, because we are talking about the sequence of events and the result. Let’s have a look at the compound sentence that we made:
| Independent clause 1 | Coordinating conjunction | Independent clause 2 |
|---|---|---|
| I got a flat tire, | so | I called a tow truck. |
Did you notice how a period got changed into a comma? This is what we usually do when we use coordinating conjunctions to create a compound sentence. Let’s have a look at more examples of compound sentences with coordinating conjunctions: * Service with a smile. * We love to serve. For this sentence, it would be better to use the conjunction for, because the sentence describes a reason why they smile.
| Independent clause 1 | Coordinating conjunction | Independent clause 2 |
|---|---|---|
| Service with a smile, | for | we love to serve. |
Can you tell which coordinating conjunction would best fit here? * We don’t take cash. * We do take card payments.
But fits best here, as the sentence gives contrast between two types of payment, giving a payment option they do accept over cash.
| Independent clause 1 | Coordinating conjunction |
Independent clause 2 |
|---|---|---|
| We don’t take cash, | but | we do take card payments. |
Simple Sentences to Compound Sentences – Summary
Let’s review what we learned about simple sentences, compound sentences and coordinating conjunctions today.
- A simple sentence is a sentence with one independent clause. An independent clause consists of a subject and a verb.
A compound sentence has two or more independent clauses. We can turn two simple sentences into a compound sentence using coordinating conjunctions.
Coordinating conjunctions are: for, and, nor, but, or, yet, so. You can remember them using the word FANBOYS.
Now you know how to write a compound sentence using coordinating conjunctions. For more examples and practice, watch the video, and use our compound and simple sentence worksheets! You can learn more about complex sentences and about coordinating conjunctions with these other videos as well!
Frequently Asked Questions about Simple and Compound Sentences
Transcript Simple Sentences to Compound Sentences
"This is not what I wanted." "Pip. I need you to bring out the machine immediately, we need some conjunctions out here!" "What do we need to fix, Koko?" "The signs! I want those simple sentences to be compound sentences, pretty please!" Let's learn with Koko and Pip all about changing simple sentences to compound sentences. A simple sentence has a single independent clause. An independent clause has a subject and a verb. A compound sentence has two or more independent clauses joined by a coordinating conjunction. A coordinating conjunction is a word that joins two or more sentences together. Coordinating conjunctions are words such as for, and, nor, but, or, yet, and so! You can remember these using the word FANBOYS! Now we know what simple sentences and compound sentences are, let's look at an example of changing simple sentences to compound senteces using FANBOYS! Here, we have two sentences. I got a flat tire. I called a tow truck. I got a flat tire is a simple sentence because it has a single independent clause. I called a tow truck is a simple sentence because it also has a single independent clause. Now we look at FANBOYS, and decide which coordinating conjunction fits best between these two simple sentences. Not all coordinating conjunctions make sense, so you must choose carefully! Since we are talking about a sequence of events, so fits best here, as it tells us what happened next to solve the problem! I got a flat tire, so I called a tow truck. When we add a coordinating conjunction, the period is usually replaced with a comma, like this. Now that we are familiar with coordinating conjunctions, let's help Koko and Pip fix some store signs! The first sign says; Service with a smile. We love to serve. Which FANBOYS word fits best here? For is the word that fits best here, since it is giving a reason why they smile. Service with a smile, for we love to serve, with a comma added here! Let's take a look at another sign. We don't take cash. We do take card payments. Which FANBOYS word fits best here? But, since it is giving a payment option they do accept over cash. We don't take cash, but we do take card payments, adding a comma here. Let's take a look at one last sign. The store is not open today. The store is not open tomorrow. Which FANBOYS word fits best here? Nor fits best here, since it is adding another negative part to the sentence. The store is not open today, nor tomorrow, replacing the period with a comma! Sometimes, you need to rewrite simple sentences when adding coordinating conjunctions. While Koko and Pip make sure they didn't miss any signs, let's review! Remember, a simple sentence can be changed to a compound sentence by adding coordinating conjunctions. Coordinating conjunctions are words such as for, and, nor, but, or, yet, and so! You can remember these using the acronym FANBOYS! "Pip! Please stop!" "Sorry, Koko. I got a little carried away!" "I'm in a sticky situation now!"
